* code for the Qlogic ISP SCSI adapters.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

A wad of changes- prepping for 1080/1240 support (which caused a massive thwank in register layout goop). A different mboxcmd approach. Some PDB change infrastructure. Some better management of loopdown/loopup events (keep them distinct from resource starvation for simq freeze/unfreeze actions).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Add in Bill Sommerfelds -Wformat changes. Set up default node && port WWNs correctly (Again!) - this time for the case that we're not going to fully init the adapter if isp_init is called (with ISP_CFG_NOINIT set in options). The pupose for this is to bring the adapter up to almost ready to go, get info out of NVRAM, but to not start it up- leaving it until later to actually start things up if wanted (and possibly with different roles selected).

Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

The pupose for this is to bring the adapter up to almost ready to go, get info out of NVRAM, but to not start it up- leaving it until later to actually start things up if wanted (and possibly with different roles selected).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some).

This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'.

This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet.

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Minor stuff: Remove ISP2100_FABRIC defines- we always handle fabric now. Insert isp_getmap helper function (for getting Loop Position map). Make sure we (for our own benefit) mark req_state_flags with RQSF_GOT_SENSE for Fibre Channel if we got sense data- the !*$)!*$)~*$)*$ Qlogic f/w doesn't do so. Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP, and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications upstream for changes in the name server, changes in the port database, and f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event. Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt. Following the manuals, allow for both Mailbox as well as Queue Reponse type interrupts for regular SCSI.

* After we've fired this chip up, zero out the conf1 register
Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt. Following the manuals, allow for both Mailbox as well as Queue Reponse type interrupts for regular SCSI.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Change the modification of what could be a const string. Apparently the construct: char *foo; ... foo = "XXX"; ... foo[1] = 'Y'; is wrong. IT blew up on NetBSD-sparc64 because that platform write-protects constant strings.

revname = "2200";
Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'.

This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt.

A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang.

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt. Following the manuals, allow for both Mailbox as well as Queue Reponse type interrupts for regular SCSI.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up.

Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt. Following the manuals, allow for both Mailbox as well as Queue Reponse type interrupts for regular SCSI.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while.

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Fix a longstanding bug- we had the sense of what bit 14 for the ICB firmware options meant- *I* had taken it to mean that if you set it, Node Name would be ignored and derived from Port Name. Actually, it meant the opposite. As a consequence- change ICBOPT_USE_PORTNAME to the define ICBOPT_BOTH_WWNS- makes more sense. Fix wrong input bitmap for MBOX_DUMP_RAM command. Call ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD control command (so outer layers can run a mailbox command directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so outer layers can understand response queue entries we might not know about.

Remove the Target mode functions until they're in better shape. Implement some suggested compilation cleanups from Eklund. Wire down a hard loop id if we are not on a platform that has the ability to get to a PCI BIOS (it still will float to the ID it gets after a LIP but at least we can try). Clarify that the expanded lun is based upon SCCLUN defines (in f/w).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu).

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

A wad of changes- prepping for 1080/1240 support (which caused a massive thwank in register layout goop). A different mboxcmd approach. Some PDB change infrastructure. Some better management of loopdown/loopup events (keep them distinct from resource starvation for simq freeze/unfreeze actions).

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt.

Fix some breakage about how we build WWNs. Do some other fabric related changes: consider a new PDB entry different if Class 3 service parameter roles change (!!!). Do some checking as we're getting a port database that traps whether things change while we're doing so. Handle N-port and F-ports correctly. Fix the fabric login loop to retain a login/binding if things haven't changed (I mean, why logout a device only to log it back in). No longer accept, after fabric logins, garbage if we can't get a PDB entry that matches the device we've just logged into- if it doesn't, log it out as it is very unlikely to still be what we thought it was. Get rid of some of the debounce loops because we could get stuck there.

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

A wad of changes- prepping for 1080/1240 support (which caused a massive thwank in register layout goop). A different mboxcmd approach. Some PDB change infrastructure. Some better management of loopdown/loopup events (keep them distinct from resource starvation for simq freeze/unfreeze actions).

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Fix some breakage about how we build WWNs. Do some other fabric related changes: consider a new PDB entry different if Class 3 service parameter roles change (!!!). Do some checking as we're getting a port database that traps whether things change while we're doing so. Handle N-port and F-ports correctly. Fix the fabric login loop to retain a login/binding if things haven't changed (I mean, why logout a device only to log it back in). No longer accept, after fabric logins, garbage if we can't get a PDB entry that matches the device we've just logged into- if it doesn't, log it out as it is very unlikely to still be what we thought it was. Get rid of some of the debounce loops because we could get stuck there.

Do some checking as we're getting a port database that traps whether things change while we're doing so. Handle N-port and F-ports correctly. Fix the fabric login loop to retain a login/binding if things haven't changed (I mean, why logout a device only to log it back in). No longer accept, after fabric logins, garbage if we can't get a PDB entry that matches the device we've just logged into- if it doesn't, log it out as it is very unlikely to still be what we thought it was.

Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so.

Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values.

Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning.

Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

In order to save ourselves grief with the SUNPRO compiler under Solaris (which, for reasons unknown to me, chokes on u_int16_t as a typedef of unsigned short if used in a transitional (mixed K&R and ANSI) way), we'll go the extra mile and fully ANSIfy things.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning.

Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

In order to save ourselves grief with the SUNPRO compiler under Solaris (which, for reasons unknown to me, chokes on u_int16_t as a typedef of unsigned short if used in a transitional (mixed K&R and ANSI) way), we'll go the extra mile and fully ANSIfy things.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0.

Roll revision levels. Add support for the Qlogic 2200 (warn about not having SCSI_ISP_SCCLUN config defined if we don't have f/w for the 2200- it's resident firmware uses SCCLUN (65535 luns)). Change the way the default LoopID is gathered (it's now a platform specific define so that some attempt at a synthetic WWN can be made in case NVRAM isn't readable). Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning.

RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt.

There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

if (IS_FC(isp)) {
Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Minor stuff: Remove ISP2100_FABRIC defines- we always handle fabric now. Insert isp_getmap helper function (for getting Loop Position map). Make sure we (for our own benefit) mark req_state_flags with RQSF_GOT_SENSE for Fibre Channel if we got sense data- the !*$)!*$)~*$)*$ Qlogic f/w doesn't do so. Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP, and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications upstream for changes in the name server, changes in the port database, and f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event. Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Fix a longstanding bug- we had the sense of what bit 14 for the ICB firmware options meant- *I* had taken it to mean that if you set it, Node Name would be ignored and derived from Port Name. Actually, it meant the opposite. As a consequence- change ICBOPT_USE_PORTNAME to the define ICBOPT_BOTH_WWNS- makes more sense. Fix wrong input bitmap for MBOX_DUMP_RAM command. Call ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD control command (so outer layers can run a mailbox command directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so outer layers can understand response queue entries we might not know about.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Update QLogic ISP support for CAM. Add preliminary target mode support. Submitted by: Matthew Jacob <mjacob@feral.com>

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt. Following the manuals, allow for both Mailbox as well as Queue Reponse type interrupts for regular SCSI.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this.

However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt. Following the manuals, allow for both Mailbox as well as Queue Reponse type interrupts for regular SCSI.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Once we have firmware running (if isp_reset) and this is the first time through, establish what our LUN width is. Unfortunately, we can't ask the f/w. If we loaded the f/w, we'll now assume we have expanded LUNs (SCCLUN for fibre channel, just plain 32 LUN for SCSI). If we didn't load firmware, assume 8 LUNs for SCSI and 1 LUN for Fibre Channel. We have to assume only one LUN for Fibre Channel because the LUN setting in Request Queue entries is in different places whether we have SCCLUN firmware or not, so the only LUN guaranteed to work for both is LUN 0. Clean up the rest of isp.c so that ISP2100_SCCLUN defines aren't used- instead use run time determinants based upon isp->isp_maxluns. After starting firmware, delay 500us to give it a chance to get rolling. Fix the interrupt service routine to check for both isr && sema being zero before thinking this was a spurious interrupt.

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

* per-platform thing. Also includes any memory barriers.
Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack.

RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now.

Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now.

Fix a longstanding bug- we had the sense of what bit 14 for the ICB firmware options meant- *I* had taken it to mean that if you set it, Node Name would be ignored and derived from Port Name. Actually, it meant the opposite. As a consequence- change ICBOPT_USE_PORTNAME to the define ICBOPT_BOTH_WWNS- makes more sense. Fix wrong input bitmap for MBOX_DUMP_RAM command. Call ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD control command (so outer layers can run a mailbox command directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so outer layers can understand response queue entries we might not know about.

Minor stuff: Remove ISP2100_FABRIC defines- we always handle fabric now. Insert isp_getmap helper function (for getting Loop Position map). Make sure we (for our own benefit) mark req_state_flags with RQSF_GOT_SENSE for Fibre Channel if we got sense data- the !*$)!*$)~*$)*$ Qlogic f/w doesn't do so. Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP, and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications upstream for changes in the name server, changes in the port database, and f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event. Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Fix a longstanding bug- we had the sense of what bit 14 for the ICB firmware options meant- *I* had taken it to mean that if you set it, Node Name would be ignored and derived from Port Name. Actually, it meant the opposite. As a consequence- change ICBOPT_USE_PORTNAME to the define ICBOPT_BOTH_WWNS- makes more sense. Fix wrong input bitmap for MBOX_DUMP_RAM command. Call ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD control command (so outer layers can run a mailbox command directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so outer layers can understand response queue entries we might not know about.

Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

Correctly send async notifications upstream for changes in the name server, changes in the port database, and f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event. Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Minor stuff: Remove ISP2100_FABRIC defines- we always handle fabric now. Insert isp_getmap helper function (for getting Loop Position map). Make sure we (for our own benefit) mark req_state_flags with RQSF_GOT_SENSE for Fibre Channel if we got sense data- the !*$)!*$)~*$)*$ Qlogic f/w doesn't do so. Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP, and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications upstream for changes in the name server, changes in the port database, and f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event. Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Fix a longstanding bug- we had the sense of what bit 14 for the ICB firmware options meant- *I* had taken it to mean that if you set it, Node Name would be ignored and derived from Port Name. Actually, it meant the opposite. As a consequence- change ICBOPT_USE_PORTNAME to the define ICBOPT_BOTH_WWNS- makes more sense. Fix wrong input bitmap for MBOX_DUMP_RAM command. Call ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD control command (so outer layers can run a mailbox command directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so outer layers can understand response queue entries we might not know about.

Minor stuff: Remove ISP2100_FABRIC defines- we always handle fabric now. Insert isp_getmap helper function (for getting Loop Position map).

Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP, and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications upstream for changes in the name server, changes in the port database, and f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event. Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

case ASYNC_DEVICE_RESET:
Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet.

Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries.

Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Fix a longstanding bug- we had the sense of what bit 14 for the ICB firmware options meant- *I* had taken it to mean that if you set it, Node Name would be ignored and derived from Port Name. Actually, it meant the opposite. As a consequence- change ICBOPT_USE_PORTNAME to the define ICBOPT_BOTH_WWNS- makes more sense. Fix wrong input bitmap for MBOX_DUMP_RAM command. Call ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD control command (so outer layers can run a mailbox command directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so outer layers can understand response queue entries we might not know about.

Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass.

This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures).

RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now.

Some massive thwunking in initialization to handle dual bus adapters. More massive thwunking to include an XS_CHANNEL value. Some changes of how parameters are reported to outer layers (including bus, e.g.). Yet more stirring around in isp_mboxcmd to try and get it right. Decode of 1080/1240 NVRAM.

Slightly cleaner fabric support (whiter whites! redder reds!).. No, seriously- only attempt to logout a previously logged in fabric device. Fix a longstanding bug for aborting overtime commands- handle halves have always been reversed. Clean up some error messages to indicate channel number. Approved:jkh

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures).

Switch to using 16 bit handles instead of 32 bit handles. This is a pretty invasive change, but there are three good reasons to do this: 1. We'll never have > 16 bits of handle. 2. We can (eventually) enable the RIO (Reduced Interrupt Operation) bits which return multiple completing 16 bit handles in mailbox registers. 3. The !)$*)$*~)@$*~)$* Qlogic target mode for parallel SCSI spec changed such that at_reserved (which was 32 bits) was split into two pieces- and one of which was a 16 bit handle id that functions like the at_rxid for Fibre Channel (a tag for the f/w to correlate CTIOs with a particular command). Since we had to muck with that and this changed the whole handler architecture, we might as well... Propagate new at_handle on through int ct_fwhandle. Follow implications of changing to 16 bit handles. These above changes at least get Qlogic 1040 cards working in target mode again. 1080/12160 cards don't work yet. In isp.c: Prepare for doing all loop management in outer layers.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this.

Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards.

I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands..

In order to save ourselves grief with the SUNPRO compiler under Solaris (which, for reasons unknown to me, chokes on u_int16_t as a typedef of unsigned short if used in a transitional (mixed K&R and ANSI) way), we'll go the extra mile and fully ANSIfy things.

#ifndef ISP_STRIPPED
Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

After loading f/w, for FC cards print out Firmware Attributes. Redo establishment of default SCSI parameters whether or not we've been compiled for target mode. Unfortunately, the Qlogic f/w is confused so that if we set all targets to be 'safe' (i.e., narrow/async), it will also then report narrow, async if we're contacted in target mode from that target (acting in initiator role). D'oh! Fix ISPCTL_TOGGLE_TMODE to correctly enable the right channel for dual channel cards. Add some more opcodes. Fix a stupid NULL pointer bug.

"GET TARGET MODE STATE",
Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Fix a longstanding bug- we had the sense of what bit 14 for the ICB firmware options meant- *I* had taken it to mean that if you set it, Node Name would be ignored and derived from Port Name. Actually, it meant the opposite. As a consequence- change ICBOPT_USE_PORTNAME to the define ICBOPT_BOTH_WWNS- makes more sense. Fix wrong input bitmap for MBOX_DUMP_RAM command. Call ISP_DUMPREGS if we get a f/w crash. Add ISPCTL_RUN_MBOXCMD control command (so outer layers can run a mailbox command directly) and add a ISPASYNC_UNHANDLED_RESPONSE hook so outer layers can understand response queue entries we might not know about.

Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

In order to save ourselves grief with the SUNPRO compiler under Solaris (which, for reasons unknown to me, chokes on u_int16_t as a typedef of unsigned short if used in a transitional (mixed K&R and ANSI) way), we'll go the extra mile and fully ANSIfy things.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass.

Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

MBOX_ACQUIRE(isp);
Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6. Occasional Constipation Of Commands.. In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

When resetting the Qlogic 2X00 units, reset the FPM (Fibre Protocol Module) and FBM (Fibre Buffer Modules). Also remember to clear the semaphore registers. Tell the RISC processor to not halt on FPM parity errors. Throw out the ISP_CFG_NOINIT silliness and instead go to the use of adapter 'roles' to see whether one completes initialization or not (mostly for Fibre Channel). The ultimate intent, btw, of all of this is to have a warm standby adapter for failover reasons. Because we do roles now, setting of Target Capable Class 3 service parameters in the ICB for the 2x00 cards reflects from role. Also, in isp_start, if we're not supporting an initiator role, we bounce outgoing commands with a Selection Timeout error. Also clean out the TOGGLE_TMODE goop for FC- there is no toggling of target mode like there is for parallel SCSI cards. Do more cleanup with respect to using target ids 0..125 in F-port topologies. Also keep track of things which *were* fabric devices so that when you rescan the fabric you can notify the outer layers when fabric devices go away. Only force a LOGOUT for fabric devices if they're still logged in (i.e., you cat their Port Database entry. Clean up the Get All Next scanning. Finally, use a new tag in the softc to store the opcode for the last mailbox command used so we can report which opcode timed out.

In running some very strenous high IOPs tests (generating about 11000 interrupts/second across one Qlogic 1040, one Qlogic 1080 and one Qlogic 2200 on an Alpha PC164), I found that I would get occasional but regular 'watchdog timeouts' on both the 1080 and the 2100 cards. This is under FreeBSD, and the watchdog timeout routine just marks the command in error and retries it. Invariably, right after this 'watchdog timeout' error, I'd get a command completion for the command that I had thought timed out. That is, I'd get a command completion, but the handle returned by the firmware mapped to no current command. The frequency of this problem is low under such a load- it would usually take an 30 minutes per 'lost' interrupt. I doubled the timeout for commands to see if it just was an edge case of waiting too short a period. This has no effect. I gathered and printed out microtimes for the watchdog completed command and the completion that couldn't find a command- it was always the case that the order of occurrence was "timeout, completion" separated by a time on the order of 100 to 150 ms. This caused me to consider 'firmware constipation' as to be a possible culprit. That is, resubmission of a command to the device that had suffered a watchdog timeout seemed to cause the presumed dead command to show back up. I added code in the watchdog routine that, when first entered for the command, marks the command with a flag, reissues a local timeout call for one second later, but also then issues a MARKER Request Queue entry to the Qlogic f/w. A MARKER entry is used typically after a Bus Reset to cause the f/w to get synchronized with respect to either a Bus, a Nexus or a Target. Since I've added this code, I always now see the occasional watchdog timeout, but the command that was about to be terminated always now seems to be completed after the MARKER entry is issued (and before the timeout extension fires, which would come back and *really* terminate the command).

/*
Fix usage of DELAY (SYS_DELAY is the platform independent local define). Fix stupidity wrt checking whether we've gone to LOOP_PDB_RCVD loopstate- it's okay to be greater than this state. D'oh! Protect calls to isp_pdb_sync and isp_fclink_state with IS_FC macros. Completely redo mailbox command routine (in preparation to make this possibly wait rather than poll for completion). Make a major attempt to solve the 'lost interrupt' problem 1. Problem The Qlogic cards would appear to 'lose' interrupts, i.e., a legitimate regular SCSI command placed on the request queue would never complete and the watchdog routine in the driver would eventually wakeup and catch it. This would typically only happen on Alphas, although a couple folks with 700MHz Intel platforms have also seen this. For a long time I thought it was a foulup with f/w negotiations of SYNC and/or WIDE as it always seemed to happen right after the platform it was running on had done a SET TARGET PARAMETERS mailbox command to (re)enable sync && wide (after initially forcing ASYNC/NARROW at startup). However, occasionally, the same thing would also occur for the Fibre Channel cards as well (which, ahem, have no SET TARGET PARAMETERS for transfer mode). After finally putting in a better set of watchdog routines for the platforms for this driver, it seemed to be the case that the command in question (usually a READ CAPACITY) just had up and died- the watchdog routine would catch it after ~10 seconds. For some platforms (NetBSD/OpenBSD)- an ABORT COMMAND mailbox command was sent (which would always fail- indicating that the f/w denied knowledge of this command, i.e., the f/w thought it was a done command). In any case, retrying the command worked. But this whole problem needed to be really fixed. 2. A False Step That Went in The Right Direction The mailbox code was completely rewritten to no longer try and grab the mailbox semaphore register and to try and 'by hand' complete async fast posting completions. It was also rewritten to now have separate in && out bitpatterns for registers to load to start and retrieve to complete. This means that isp_intr now handles mailbox completions. This substantially simplifies the mailbox handling code, and carries things 90% toward getting this to be a non-polled routine for this driver. This did not solve the problem, though. 3. Register Debouncing I saw some comments in some errata sheets and some notes in a Qlogic produced Linux driver (for the Qlogic 2100) that seemed to indicate that debouncing of reads of the mailbox registers might be needed, so I added this. This did not affect the problem. In fact, it made the problem worse for non-2100 cards. 5. Interrupt masking/unmasking The driver *used* to do a substantial amount of masking/unmasking of the interrupt control register. This was done to make sure that the core common code could just assume it would never get pre-empted. This apparently substantially contributed to the lost interrupt problem. The rewrite of the ICR (Interrupt Control Register), which is a separate register from the ISR (Interrupt Status Register) should not have caused any change to interrupt assertions pending. The manual does not state that it will, and the register layout seems to imply that the ICR is just an active route gate. We only enable PCI Interrupts and RISC Interrupts- this should mean that when the f/w asserts a RISC interrupt and (and the ICR allows RISC Interrupts) and we have PCI Interrupts enabled, we should get a PCI interrupt. Apparently this is a latch- not a signal route. Removing this got rid of *most* but not all, lost interrupts. 5. Watchdog Smartening I made sure that the watchdog routine would catch cases where the Qlogic's ISR showed an interrupt assertion. The watchdog routine now calls the interrupt service routine if it sees this. Some additional internal state flags were added so that the watchdog routine could then know whether the command it was in the middle of burying (because we had time it out) was in fact completed by the interrupt service routine. 6.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

isp_prt(isp, ISP_LOGDEBUG0,
Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Change initialization of options a bit- don't use ADISC. Set FullDuplex mode if config options tells us to do so. Do not use FULL_LOGIN after LIP- it's the right thing to do but it causes too much loop disruption (Loop Resets). Sanity check some default values. Redo construction of port and node WWNs based upon what we have- if we have 2 in the top nibble, we can have distinct port and node WWNs. Clean up some SCCLUN related code that we obviously had never compiled (:-(). Audit commands coming int ispscsicmd and don't throw commands at Fibre devices that do not have Class 3 service parameters TARGET ROLE defined. Clean up f/w initialization a bit. Add Fabric support (or at least the first blush of it). Whew - way too much to describe here. Basically, after a LIP, hang out until we see a Loop Up or a Port DataBase Change async event, then see if we're on a Fabric (GET_PORT_NAME of FL_PORT_ID). If we are, try and scan the fabric controller for fabric devices using the GetAllNext SNS subcommand. As we find devices, announce them to the outer layer. Try and do some guard code for broken (Brocade) SNS servers (that get stuck in loops- gotta maybe do this a different way using the GP_ID3 cmd instead). Then do a scan of the lower (local loop) ids using a GET_PORT_NAME to see if the f/w has logged into anything at that loop id. If so, then do a GET_PORT_DATABASE command. Do this scan into a local database. At this point we can say the loop is 'Ready'. After this, we merge our local loop port database with our stored port database- in a as yet to be really fully exercised fashion we try and follow the logic of something having moved around. The first time we see something at a Loop ID, we fix it, for the purpose of this system instance, at that Loop ID. If things shift around so it ends up somewhere else, we still keep it at this Loop ID (our 'Target') but use the new (moved) Loop ID when we actually throw commands at it. Check for insane cases of different Loop IDs both claiming to have the same WWN- if that happens, invalidate both. Notify the outer layer of devices that have arrived and devices that have gone away. *Finally*, when this is done, search the softc's database of Fabric devices and perform logout/login actions. The Qlogic f/w maintains logout/login for all local loop devices. We have to maintain logout/login for fabric devices- total PITA. Expect to see this area undergo more change over time.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Do some checking as we're getting a port database that traps whether things change while we're doing so. Handle N-port and F-ports correctly. Fix the fabric login loop to retain a login/binding if things haven't changed (I mean, why logout a device only to log it back in). No longer accept, after fabric logins, garbage if we can't get a PDB entry that matches the device we've just logged into- if it doesn't, log it out as it is very unlikely to still be what we thought it was.

This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'.

* Re-initialize the ISP and complete all orphaned commands
Remove some target mode stuff. It will get re-introduced in a different file later. Do some pencil-sharpening types of minor changes. Change how active commands are remembered (using new inline functions to get handles, etc..). Now do a GET FIRMWARE STATUS after firing up the f/w as outgoing mailbox 2 will tell you the f/w's notion of the max commands that can be supported. Attempt to retrieve loop topology. Add in the appropriate SWIZZLE/UNSWIZZLE macros calls (this is a no-op on Little Endian machines but is needed for sparc (on other platforms)). Move the temp port database we use to find out where things have moved to after a LIP to the softc and off the kernel stack. Follow Qlogic's hint and don't bother setting a tag for commands that don't have this enabled (presumably the f/w will do it's own selection then). Use an INT_PENDING macro to check for an interrupt. The call to ISP_DMAFREE now just takes the handle- not the 'handle-1' which was a layering violation. Use CFGPRINTF in a couple of places to make things less chatty if not booting verbose, or CAMDEBUG compiles, etc..

In order to save ourselves grief with the SUNPRO compiler under Solaris (which, for reasons unknown to me, chokes on u_int16_t as a typedef of unsigned short if used in a transitional (mixed K&R and ANSI) way), we'll go the extra mile and fully ANSIfy things.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into.

This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt. There are seperate print levels that can be independently set (see ispvar.h), which include debugging, etc. All SYS_DELAY macros are now USEC_DELAY macros. RQUEST_QUEUE_LEN and RESULT_QUEUE_LEN now take ispsoftc as a parameter- the Fibre Channel cards and the Ultra2/Ultra3 cards can have 16 bit request queue entry indices, so we can make a 1024 entry index for them instead of the 256 entries we've had until now. A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

A major change it to fix isp_fclink_test to actually only wait the delay of time specified in the microsecond argument being passed. The problem has always been that a call to isp_mboxcmd to get he current firmware state takes an unknown (sometimes long) amount of time- this is if the firmware is busy doing PLOGIs while we ask it what's up. So, up until now, the usdelay argument has been a joke. The net effect has been that if you boot without being plugged into a good loop or into a switch, you hang. Massively annonying, and hard to fix because the actual time delta was impossible to know from just guessing. Now, using the new GET_NANOTIME macros, a precise and measured amount of USEC_DELAY calls are done so that only the specified usecdelay is allowed to pass. This means that if the initial startup of the firmware if followed by a call from isp_freebsd.c:isp_attach to isp_control(isp, ISP_FCLINK_TEST, &tdelay) where tdelay is 2 * 1000000, no more than two seconds will actually elapse before we leave concluding that the cable is unhooked. Jeez. About time.... Change the ispscsicmd entry point to isp_start, and the XS_CMD_DONE macro to a call to the platform supplied isp_done (sane naming). Limit our size of request queue completions we'll look at at interrupt time. Since we've increased the size of the Request Queue (and the size of the Response Queue proportionally), let's not create an interrupt stack overflow by having to keep a max completion list (forw links are not an option because this is common code with some platforms that don't have link space in their XS_T structures). A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries.

Major whacking for core version 2.0. A major motivator for 2.0 and these changes is that there's now a Solaris port of this driver, so some things in the core version had to change (not much, but some). In order, from the top.....: A lot of error strings are gathered in one place at the head of the file. This caused me to rewrite them to look consistent (with respect to things like 'Port 0x%' and 'Target %d' and 'Loop ID 0x%x'. The major mailbox function, isp_mboxcmd, now takes a third argument, which is a mask that selectively says whether mailbox command failures will be logged. This will substantially reduce a lot of spurious noise from the driver. At the first run through isp_reset we used to try and get the current running firmware's revision by issuing a mailbox command. This would invariably fail on alpha's with anything but a Qlogic 1040 since SRM doesn't *start* the f/w on these cards. Instead, we now see whether we're sitting ROM state before trying to get a running BIOS loaded f/w version. All CFGPRINTF/PRINTF/IDPRINTF macros have been replaced with calls to isp_prt.

A limit of 32 is not unreasonable- I doubt there'd be even this many request queue completions at a time- remember, most boards now use fast posting for normal command completion instead of filling out response queue entries. In the isp_mboxcmd cleanup, also create an array of command names so that "ABOUT FIRMWARE" can be printed instead of "CMD #8". Remove the isp_lostcmd function- it's been deprecated for a while. Remove isp_dumpregs- the ISP_DUMPREGS goes to the specific bus register dump fucntion. Various other cleanups.

Redo how default Node and Port WWNs are determined (again!). This is so we don't stomp on the differences between ports for a Qlogic 2202.

Fix some breakage about how we build WWNs. Do some other fabric related changes: consider a new PDB entry different if Class 3 service parameter roles change (!!!). Do some checking as we're getting a port database that traps whether things change while we're doing so. Handle N-port and F-ports correctly. Fix the fabric login loop to retain a login/binding if things haven't changed (I mean, why logout a device only to log it back in). No longer accept, after fabric logins, garbage if we can't get a PDB entry that matches the device we've just logged into- if it doesn't, log it out as it is very unlikely to still be what we thought it was. Get rid of some of the debounce loops because we could get stuck there.

Restructure nvram reading routine to split out to separate functions for 1020/1X80/12160/2X00- for readability. Add in 12160 (Ultra3) support- but not with PPR just yet. Fix and clarify fetching of return parameter for getting firmware rev which for the 2200 contains the connection topology (Private Loop (NL-port), N-port, FL-port, F-port). Synthesize the connection topology for the 2100 which can only be Private Loop or FL-port. Handle a couple of new async mailbox commands which signify connection in Point-to-Point mode (N-port or F-port) or indicate various toe stubbing getting to same. Approved: jkh@freebsd.org
