Add support for the Qlogic ISP SCSI && FC/AL Adapters
1998-04-22 17:54:58 +00:00
/*
* Platform (FreeBSD) dependent common attachment code for Qlogic 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.

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right. But you have to start somewhere, and this will begin to teach us how to DTRT for HBAs, etc. -- Start putting in prototype 2300 support.

Add in the enabling of interrupts (to isp_attach). Clean up a busted comment. Check against firmware state- not loop state when enabling target mode. Other changes have to do with no longer enabling/disabling interrupts at will. Rearchitect command watchdog timeouts- First of all, set the timeout period for a command that has a timeout (in isp_action) to the period of time requested *plus* two seconds. We don't want the Qlogic firmware and the host system to race each other to report a dead command (the watchdog is there to catch dead and/or broken firmware). Next, make sure that the command being watched isn't done yet. If it's not done yet, check for INT_PENDING and call isp_intr- if that said it serviced an interrupt, check to see whether the command is now done (this is what the "IN WATCHDOG" private flag is for- if isp_intr completes the command, it won't call xpt_done on it because isp_watchdog is still looking at the command). If no interrupt was pending, or the command wasn't completed, check to see if we've set the private 'grace period' flag. If so, the command really *is* dead, so report it as dead and complete it with a CAM_CMD_TIMEOUT value. If the grace period flag wasn't set, set it and issue a SYNCHRONIZE_ALL Marker Request Queue entry and re-set the timeout for one second from now (see Revision 1.45 isp.c notes for more on this) to give the firmware a final chance to complete this command.

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

Make a static chain of isp softcs- gdb usage becomes a lot easier. Add in a very large amount of target mode support code- this is just a first pass at this. It's a difficult thing because some of the code can be in platform independent areas (see isp_target.?) but a lot has to be in platform dependent areas because of not only the tight coupling of received commands/events and the specific OS subsystem but because the platform independent code has (deliberately) no event/wait mechanisms.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

Begin to implement target mode that for Fibre Channel has a private per-command component that we *don't* try and pass thru CAM. CAM just is too risky and too much of a pain- structures get copied, but not all info of interest can be considered safely transported thru all consumers (including user space) from the incoming ATIO to the outgoing CTIO- it's just much safer to have a buddy structure, identified by the command's tag which *does* make it thru safely.

Add a isp_target_putback_atio- we aren't using CCINCR at this time, so we need a function that tells the Qlogic f/w that a target mode command is done, so increase the resource count for that lun. Add in a timeout function to kick the putback again if we fail to do it the first time (we may not have the request queue space for ATIO push). Split the function isp_handle_platform_ctio into two parts so that the timeout function for the ATIO push or isp_handle_platform_ctio can inform CAM that the requested CTIO(s) are now done. Clean up (cough) residual handling. What we need for Fibre Channel is to preserve the at_datalen field from the original incoming ATIO so we can calculate a 'true' residual. Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in. Make sure we propage 'suggested' sense data from the incoming ATIO into the created system ATIO- and set sense_len appropriately. Correctly propagate tag values. Fall back to the model of generating (well, the functions in isp_pci.c do the work) multiple CTIOs based upon what we get from XPT. Instead of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed to us from XPT, and if it implies that we have to generate extra Qlogic CTIOs, so be it. This means that we have to wait until the last CTIO in a sequence we generated completes before calling xpt_done. Executive summary- target mode actually now pretty much works well enough to tell folks about.

A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable.

Make a static chain of isp softcs- gdb usage becomes a lot easier. Add in a very large amount of target mode support code- this is just a first pass at this. It's a difficult thing because some of the code can be in platform independent areas (see isp_target.?) but a lot has to be in platform dependent areas because of not only the tight coupling of received commands/events and the specific OS subsystem but because the platform independent code has (deliberately) no event/wait mechanisms.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable.

Begin to implement target mode that for Fibre Channel has a private per-command component that we *don't* try and pass thru CAM. CAM just is too risky and too much of a pain- structures get copied, but not all info of interest can be considered safely transported thru all consumers (including user space) from the incoming ATIO to the outgoing CTIO- it's just much safer to have a buddy structure, identified by the command's tag which *does* make it thru safely. Pay attention to link speed and report 200MB/s xfer speed for a 23XX card in 2GPs mode. MFC after: 1 week

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right. But you have to start somewhere, and this will begin to teach us how to DTRT for HBAs, etc. -- Start putting in prototype 2300 support. Add back in LIP and Loop Reset as async events that each platform will handle. Add in another int_bogus instrumentation point. Do some more substantial target mode cleanups. MFC after: 8 weeks

Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable.

Make a static chain of isp softcs- gdb usage becomes a lot easier. Add in a very large amount of target mode support code- this is just a first pass at this. It's a difficult thing because some of the code can be in platform independent areas (see isp_target.?) but a lot has to be in platform dependent areas because of not only the tight coupling of received commands/events and the specific OS subsystem but because the platform independent code has (deliberately) no event/wait mechanisms.

out:
I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

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 restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Add a isp_target_putback_atio- we aren't using CCINCR at this time, so we need a function that tells the Qlogic f/w that a target mode command is done, so increase the resource count for that lun. Add in a timeout function to kick the putback again if we fail to do it the first time (we may not have the request queue space for ATIO push). Split the function isp_handle_platform_ctio into two parts so that the timeout function for the ATIO push or isp_handle_platform_ctio can inform CAM that the requested CTIO(s) are now done. Clean up (cough) residual handling. What we need for Fibre Channel is to preserve the at_datalen field from the original incoming ATIO so we can calculate a 'true' residual. Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in. Make sure we propage 'suggested' sense data from the incoming ATIO into the created system ATIO- and set sense_len appropriately. Correctly propagate tag values. Fall back to the model of generating (well, the functions in isp_pci.c do the work) multiple CTIOs based upon what we get from XPT. Instead of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed to us from XPT, and if it implies that we have to generate extra Qlogic CTIOs, so be it. This means that we have to wait until the last CTIO in a sequence we generated completes before calling xpt_done. Executive summary- target mode actually now pretty much works well enough to tell folks about.

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 restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in. Make sure we propage 'suggested' sense data from the incoming ATIO into the created system ATIO- and set sense_len appropriately. Correctly propagate tag values. Fall back to the model of generating (well, the functions in isp_pci.c do the work) multiple CTIOs based upon what we get from XPT. Instead of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed to us from XPT, and if it implies that we have to generate extra Qlogic CTIOs, so be it. This means that we have to wait until the last CTIO in a sequence we generated completes before calling xpt_done. Executive summary- target mode actually now pretty much works well enough to tell folks about.

Begin to implement target mode that for Fibre Channel has a private per-command component that we *don't* try and pass thru CAM. CAM just is too risky and too much of a pain- structures get copied, but not all info of interest can be considered safely transported thru all consumers (including user space) from the incoming ATIO to the outgoing CTIO- it's just much safer to have a buddy structure, identified by the command's tag which *does* make it thru safely.

A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will).

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 restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating.

Add in the enabling of interrupts (to isp_attach). Clean up a busted comment. Check against firmware state- not loop state when enabling target mode. Other changes have to do with no longer enabling/disabling interrupts at will. Rearchitect command watchdog timeouts- First of all, set the timeout period for a command that has a timeout (in isp_action) to the period of time requested *plus* two seconds. We don't want the Qlogic firmware and the host system to race each other to report a dead command (the watchdog is there to catch dead and/or broken firmware). Next, make sure that the command being watched isn't done yet. If it's not done yet, check for INT_PENDING and call isp_intr- if that said it serviced an interrupt, check to see whether the command is now done (this is what the "IN WATCHDOG" private flag is for- if isp_intr completes the command, it won't call xpt_done on it because isp_watchdog is still looking at the command). If no interrupt was pending, or the command wasn't completed, check to see if we've set the private 'grace period' flag. If so, the command really *is* dead, so report it as dead and complete it with a CAM_CMD_TIMEOUT value. If the grace period flag wasn't set, set it and issue a SYNCHRONIZE_ALL Marker Request Queue entry and re-set the timeout for one second from now (see Revision 1.45 isp.c notes for more on this) to give the firmware a final chance to complete this command.

This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in.

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Add a isp_target_putback_atio- we aren't using CCINCR at this time, so we need a function that tells the Qlogic f/w that a target mode command is done, so increase the resource count for that lun. Add in a timeout function to kick the putback again if we fail to do it the first time (we may not have the request queue space for ATIO push). Split the function isp_handle_platform_ctio into two parts so that the timeout function for the ATIO push or isp_handle_platform_ctio can inform CAM that the requested CTIO(s) are now done. Clean up (cough) residual handling. What we need for Fibre Channel is to preserve the at_datalen field from the original incoming ATIO so we can calculate a 'true' residual. Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in. Make sure we propage 'suggested' sense data from the incoming ATIO into the created system ATIO- and set sense_len appropriately. Correctly propagate tag values. Fall back to the model of generating (well, the functions in isp_pci.c do the work) multiple CTIOs based upon what we get from XPT. Instead of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed to us from XPT, and if it implies that we have to generate extra Qlogic CTIOs, so be it.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode.

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.

Make a static chain of isp softcs- gdb usage becomes a lot easier. Add in a very large amount of target mode support code- this is just a first pass at this. It's a difficult thing because some of the code can be in platform independent areas (see isp_target.?) but a lot has to be in platform dependent areas because of not only the tight coupling of received commands/events and the specific OS subsystem but because the platform independent code has (deliberately) no event/wait mechanisms.

Add a isp_target_putback_atio- we aren't using CCINCR at this time, so we need a function that tells the Qlogic f/w that a target mode command is done, so increase the resource count for that lun. Add in a timeout function to kick the putback again if we fail to do it the first time (we may not have the request queue space for ATIO push). Split the function isp_handle_platform_ctio into two parts so that the timeout function for the ATIO push or isp_handle_platform_ctio can inform CAM that the requested CTIO(s) are now done. Clean up (cough) residual handling. What we need for Fibre Channel is to preserve the at_datalen field from the original incoming ATIO so we can calculate a 'true' residual. Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in. Make sure we propage 'suggested' sense data from the incoming ATIO into the created system ATIO- and set sense_len appropriately. Correctly propagate tag values. Fall back to the model of generating (well, the functions in isp_pci.c do the work) multiple CTIOs based upon what we get from XPT. Instead of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed to us from XPT, and if it implies that we have to generate extra Qlogic CTIOs, so be it. This means that we have to wait until the last CTIO in a sequence we generated completes before calling xpt_done. Executive summary- target mode actually now pretty much works well enough to tell folks about.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode.

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.

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.

Add a isp_target_putback_atio- we aren't using CCINCR at this time, so we need a function that tells the Qlogic f/w that a target mode command is done, so increase the resource count for that lun. Add in a timeout function to kick the putback again if we fail to do it the first time (we may not have the request queue space for ATIO push). Split the function isp_handle_platform_ctio into two parts so that the timeout function for the ATIO push or isp_handle_platform_ctio can inform CAM that the requested CTIO(s) are now done. Clean up (cough) residual handling. What we need for Fibre Channel is to preserve the at_datalen field from the original incoming ATIO so we can calculate a 'true' residual. Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in. Make sure we propage 'suggested' sense data from the incoming ATIO into the created system ATIO- and set sense_len appropriately. Correctly propagate tag values. Fall back to the model of generating (well, the functions in isp_pci.c do the work) multiple CTIOs based upon what we get from XPT. Instead of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed to us from XPT, and if it implies that we have to generate extra Qlogic CTIOs, so be it. This means that we have to wait until the last CTIO in a sequence we generated completes before calling xpt_done. Executive summary- target mode actually now pretty much works well enough to tell folks about.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode.

Begin to implement target mode that for Fibre Channel has a private per-command component that we *don't* try and pass thru CAM. CAM just is too risky and too much of a pain- structures get copied, but not all info of interest can be considered safely transported thru all consumers (including user space) from the incoming ATIO to the outgoing CTIO- it's just much safer to have a buddy structure, identified by the command's tag which *does* make it thru safely.

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right. But you have to start somewhere, and this will begin to teach us how to DTRT for HBAs, etc. -- Start putting in prototype 2300 support. Add back in LIP and Loop Reset as async events that each platform will handle. Add in another int_bogus instrumentation point. Do some more substantial target mode cleanups. MFC after: 8 weeks

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right. But you have to start somewhere, and this will begin to teach us how to DTRT for HBAs, etc. -- Start putting in prototype 2300 support. Add back in LIP and Loop Reset as async events that each platform will handle. Add in another int_bogus instrumentation point. Do some more substantial target mode cleanups. MFC after: 8 weeks

If no interrupt was pending, or the command wasn't completed, check to see if we've set the private 'grace period' flag. If so, the command really *is* dead, so report it as dead and complete it with a CAM_CMD_TIMEOUT value. If the grace period flag wasn't set, set it and issue a SYNCHRONIZE_ALL Marker Request Queue entry and re-set the timeout for one second from now (see Revision 1.45 isp.c notes for more on this) to give the firmware a final chance to complete this command.

Major restructuring for swizzling to the request queue and unswizzling from the response queue. Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

Instead of the ad hoc ISP_SWIZZLE_REQUEST, we now have a complete set of inline functions in isp_inline.h. Each platform is responsible for providing just one of a set of ISP_IOX_{GET,PUT}{8,16,32} macros. The reason this needs to be done is that we need to have a single set of functions that will work correctly on multiple architectures for both little and big endian machines. It also needs to work correctly in the case that we have the request or response queues in memory that has to be treated specially (e.g., have ddi_dma_sync called on it for Solaris after we update it or before we read from it). It also has to handle the SBus cards (for platforms that have them) which, while on a Big Endian machine, do *not* require *most* of the request/response queue entry fields to be swizzled or unswizzled. One thing that falls out of this is that we no longer build requests in the request queue itself. Instead, we build the request locally (e.g., on the stack) and then as part of the swizzling operation, copy it to the request queue entry we've allocated. I thought long and hard about whether this was too expensive a change to make as it in a lot of cases requires an extra copy. On balance, the flexbility is worth it. With any luck, the entry that we build locally stays in a processor writeback cache (after all, it's only 64 bytes) so that the cost of actually flushing it to the memory area that is the shared queue with the PCI device is not all that expensive. We may examine this again and try to get clever in the future to try and avoid copies. Another change that falls out of this is that MEMORYBARRIER should be taken a lot more seriously. The macro ISP_ADD_REQUEST does a MEMORYBARRIER on the entry being added. But there had been many other places this had been missing. It's now very important that it be done. Additional changes: Fix a longstanding buglet of sorts. When we get an entry via isp_getrqentry, the iptr value that gets returned is the value we intend to eventually plug into the ISP registers as the entry *one past* the last one we've written- *not* the current entry we're updating. All along we've been calling sync functions on the wrong index value. Argh. The 'fix' here is to rename all 'iptr' variables as 'nxti' to remember that this is the 'next' pointer- not the current pointer. Devote a single bit to mboxbsy- and set aside bits for output mbox registers that we need to pick up- we can have at least one command which does not have any defined output registers (MBOX_EXECUTE_FIRMWARE).

We don't want the Qlogic firmware and the host system to race each other to report a dead command (the watchdog is there to catch dead and/or broken firmware). Next, make sure that the command being watched isn't done yet. If it's not done yet, check for INT_PENDING and call isp_intr- if that said it serviced an interrupt, check to see whether the command is now done (this is what the "IN WATCHDOG" private flag is for- if isp_intr completes the command, it won't call xpt_done on it because isp_watchdog is still looking at the command). If no interrupt was pending, or the command wasn't completed, check to see if we've set the private 'grace period' flag. If so, the command really *is* dead, so report it as dead and complete it with a CAM_CMD_TIMEOUT value. If the grace period flag wasn't set, set it and issue a SYNCHRONIZE_ALL Marker Request Queue entry and re-set the timeout for one second from now (see Revision 1.45 isp.c notes for more on this) to give the firmware a final chance to complete this command.

Add in the enabling of interrupts (to isp_attach). Clean up a busted comment. Check against firmware state- not loop state when enabling target mode. Other changes have to do with no longer enabling/disabling interrupts at will. Rearchitect command watchdog timeouts- First of all, set the timeout period for a command that has a timeout (in isp_action) to the period of time requested *plus* two seconds. We don't want the Qlogic firmware and the host system to race each other to report a dead command (the watchdog is there to catch dead and/or broken firmware). Next, make sure that the command being watched isn't done yet. If it's not done yet, check for INT_PENDING and call isp_intr- if that said it serviced an interrupt, check to see whether the command is now done (this is what the "IN WATCHDOG" private flag is for- if isp_intr completes the command, it won't call xpt_done on it because isp_watchdog is still looking at the command). If no interrupt was pending, or the command wasn't completed, check to see if we've set the private 'grace period' flag. If so, the command really *is* dead, so report it as dead and complete it with a CAM_CMD_TIMEOUT value. If the grace period flag wasn't set, set it and issue a SYNCHRONIZE_ALL Marker Request Queue entry and re-set the timeout for one second from now (see Revision 1.45 isp.c notes for more on this) to give the firmware a final chance to complete this command.

Add a isp_target_putback_atio- we aren't using CCINCR at this time, so we need a function that tells the Qlogic f/w that a target mode command is done, so increase the resource count for that lun. Add in a timeout function to kick the putback again if we fail to do it the first time (we may not have the request queue space for ATIO push). Split the function isp_handle_platform_ctio into two parts so that the timeout function for the ATIO push or isp_handle_platform_ctio can inform CAM that the requested CTIO(s) are now done. Clean up (cough) residual handling. What we need for Fibre Channel is to preserve the at_datalen field from the original incoming ATIO so we can calculate a 'true' residual. Unfortunately, we're not guaranteed to get that back from CAM. We'll *try* to find it hiding in the periph_priv field (layering violation)- but if an ATIO was passed in from user land- forget it. This means that we'll probably get residuals wrong for Fibre Channel commands we're completing with an error. It's too late to 4.1 release to fix this- too bad. Luckily the only device we'd really care about this occurring on is a tape device and they're still so rare as FC attached devices that this can be considered an untested combination anyway. Remove all CCINCR usage (resource autoreplenish). When we've proved to ourself that things are working properly, we can add it back in. Make sure we propage 'suggested' sense data from the incoming ATIO into the created system ATIO- and set sense_len appropriately. Correctly propagate tag values. Fall back to the model of generating (well, the functions in isp_pci.c do the work) multiple CTIOs based upon what we get from XPT. Instead of being able to pair Qlogic generated ATIOs with CAM ATIOs, and then to pair CAM CTIOs with Qlogic CTIOs, we have to take the CTIO passed to us from XPT, and if it implies that we have to generate extra Qlogic CTIOs, so be it. This means that we have to wait until the last CTIO in a sequence we generated completes before calling xpt_done. Executive summary- target mode actually now pretty much works well enough to tell folks about.

Clean up some target mode debug messages. Fix (finally, I believe) Andrew's problems with SCSI on some alphas- do not call isp_update directly to update parameters- just mark them as being ready to update for the next command- the system would just hang on a READ CAPACITY for a drive. Really annoying because it wouldn't even timeout (and it has a timeout) so either the SET PARAMETERS call was nuking things or the f/w was really dropping the ball. approved: jkh Reviewed by: gallatin@freebsd.org

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right. But you have to start somewhere, and this will begin to teach us how to DTRT for HBAs, etc. -- Start putting in prototype 2300 support. Add back in LIP and Loop Reset as async events that each platform will handle. Add in another int_bogus instrumentation point. Do some more substantial target mode cleanups. MFC after: 8 weeks

Begin to implement target mode that for Fibre Channel has a private per-command component that we *don't* try and pass thru CAM.

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system.

Add a number of interrelated CAM feature enhancements and bug fixes. NOTE: These changes will require recompilation of any userland applications, like cdrecord, xmcd, etc., that use the CAM passthrough interface. A make world is recommended. camcontrol.[c8]: - We now support two new commands, "tags" and "negotiate". - The tags commands allows users to view the number of tagged openings for a device as well as a number of other related parameters, and it allows users to set tagged openings for a device. - The negotiate command allows users to enable and disable disconnection and tagged queueing, set sync rates, offsets and bus width. Note that not all of those features are available for all controllers. Only the adv, ahc, and ncr drivers fully support all of the features at this point. Some cards do not allow the setting of sync rates, offsets and the like, and some of the drivers don't have any facilities to do so. Some drivers, like the adw driver, only support enabling or disabling sync negotiation, but do not support setting sync rates. - new description in the camcontrol man page of how to format a disk - cleanup of the camcontrol inquiry command - add support in the 'devlist' command for skipping unconfigured devices if -v was not specified on the command line. - make use of the new base_transfer_speed in the path inquiry CCB. - fix CCB bzero cases cam_xpt.c, cam_sim.[ch], cam_ccb.h: - new flags on many CCB function codes to designate whether they're non-immediate, use a user-supplied CCB, and can only be passed from userland programs via the xpt device. Use these flags in the transport layer and pass driver to categorize CCBs. - new flag in the transport layer device matching code for device nodes that indicates whether a device is unconfigured - bump the CAM version from 0x10 to 0x11 - Change the CAM ioctls to use the version as their group code, so we can force users to recompile code even when the CCB size doesn't change. - add + fill in a new value in the path inquiry CCB, base_transfer_speed. Remove a corresponding field from the cam_sim structure, and add code to every SIM to set this field to the proper value. - Fix the set transfer settings code in the transport layer. scsi_cd.c: - make some variables volatile instead of just casting them in various places - fix a race condition in the changer code - attach unless we get a "logical unit not supported" error. This should fix all of the cases where people have devices that return weird errors when they don't have media in the drive. scsi_da.c: - attach unless we get a "logical unit not supported" error scsi_pass.c: - for immediate CCBs, just malloc a CCB to send the user request in.

Begin to implement target mode that for Fibre Channel has a private per-command component that we *don't* try and pass thru CAM. CAM just is too risky and too much of a pain- structures get copied, but not all info of interest can be considered safely transported thru all consumers (including user space) from the incoming ATIO to the outgoing CTIO- it's just much safer to have a buddy structure, identified by the command's tag which *does* make it thru safely. Pay attention to link speed and report 200MB/s xfer speed for a 23XX card in 2GPs mode. MFC after: 1 week

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).

Rearchitect command watchdog timeouts- First of all, set the timeout period for a command that has a timeout (in isp_action) to the period of time requested *plus* two seconds. We don't want the Qlogic firmware and the host system to race each other to report a dead command (the watchdog is there to catch dead and/or broken firmware). Next, make sure that the command being watched isn't done yet. If it's not done yet, check for INT_PENDING and call isp_intr- if that said it serviced an interrupt, check to see whether the command is now done (this is what the "IN WATCHDOG" private flag is for- if isp_intr completes the command, it won't call xpt_done on it because isp_watchdog is still looking at the command). If no interrupt was pending, or the command wasn't completed, check to see if we've set the private 'grace period' flag. If so, the command really *is* dead, so report it as dead and complete it with a CAM_CMD_TIMEOUT value. If the grace period flag wasn't set, set it and issue a SYNCHRONIZE_ALL Marker Request Queue entry and re-set the timeout for one second from now (see Revision 1.45 isp.c notes for more on this) to give the firmware a final chance to complete this command.

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right. But you have to start somewhere, and this will begin to teach us how to DTRT for HBAs, etc. -- Start putting in prototype 2300 support. Add back in LIP and Loop Reset as async events that each platform will handle. Add in another int_bogus instrumentation point. Do some more substantial target mode cleanups. MFC after: 8 weeks

Spring MegaChange #1. ---- Make a device for each ISP- really usable only with devfs and add an ioctl entry point (this can be used to (re)set debug levels, reset the HBA, rescan the fabric, issue lips, etc). ---- Add in a kernel thread for Fibre Channel cards. The purpose of this thread is to be woken up to clean up after Fibre Channel events block things. Basically, any FC event that casts doubt on the location or identify of FC devices blocks the queues. When, and if, we get the PORT DATABASE CHANGED or NAME SERVER DATABASE CHANGED async event, we activate the kthread which will then, in full thread context, re-evaluate the local loop and/or the fabric. When it's satisfied that things are stable, it can then release the blocked queues and let commands flow again. The prior mechanism was a lazy evaluation. That is, the next command to come down the pipe after change events would pay the full price for re-evaluation. And if this was done off of a softcall, it really could hang up the system. These changes brings the FreeBSD port more in line with the Solaris, Linux and NetBSD ports. It also, more importantly, gets us being more proactive about topology changes which could then be reflected upwards to CAM so that the periph driver can be informed sooner rather than later when things arrive or depart. --- Add in the (correct) usage of locking macros- we now have lock transition macros which allow us to transition from holding the CAM lock (Giant) and grabbing the softc lock and vice versa. Switch over to having this HBA do real locking. Some folks claim this won't be a win. They're right. But you have to start somewhere, and this will begin to teach us how to DTRT for HBAs, etc. -- Start putting in prototype 2300 support. Add back in LIP and Loop Reset as async events that each platform will handle. Add in another int_bogus instrumentation point. Do some more substantial target mode cleanups. MFC after: 8 weeks

Make a static chain of isp softcs- gdb usage becomes a lot easier. Add in a very large amount of target mode support code- this is just a first pass at this. It's a difficult thing because some of the code can be in platform independent areas (see isp_target.?) but a lot has to be in platform dependent areas because of not only the tight coupling of received commands/events and the specific OS subsystem but because the platform independent code has (deliberately) no event/wait mechanisms.

I don't know what I was thinking- if I have two separate busses on on SIM (as is true for the 1280 and the 12160), then I have to have separate flags && status for *both* busses. *Whap*. Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

Implement condition variables for coordination with some target mode events. It's nice to use these and not panic in obscure little places in the kernel like 'propagate_priority' just because we went to sleep holding a mutex, or some other absurd thing. Remove some bogus ISP_UNLOCK calls. *Whap*. No longer require that somebody do a lun enable on the wildcard device to enable target mode. They are, in fact, orthogonal. A wildcard open is a statement that somebody upstream is willing to accept commands which are otherwise unrouteable. Now, for QLogic regular SCSI target mode, this won't matter for a damn because we'll never see ATIOs for luns we haven't enabled (are listening for, if you will). But for SCCLUN fibre channel SCSI, we get all kinds of ATIOs. We can either reflect them back here with minimal info (which is isp_target.c:isp_endcmd() is for), or the wildcard device (nominally targbh) can handle them. Do further checking against firmware attributes to see whether we can, in fact, support target mode in Fibre Channel. For now, require SCCLUN f/w to supoprt FC target mode. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

Make a static chain of isp softcs- gdb usage becomes a lot easier. Add in a very large amount of target mode support code- this is just a first pass at this. It's a difficult thing because some of the code can be in platform independent areas (see isp_target.?) but a lot has to be in platform dependent areas because of not only the tight coupling of received commands/events and the specific OS subsystem but because the platform independent code has (deliberately) no event/wait mechanisms.

Add CAM_NEW_TRAN_CODE support. Use correct CAMLOCK_2_ISPLOCK macros.
