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.

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).

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).

static int isp_handle_other_response
Clean up stupidity in the isp_handle_other_response function- indexes of queue entries have to be at least 16 bits now! If we're running a 2100 less than rev 5, turn off loop fairness (per Qlogic errata). Fix typo in checking against 2200 F/W revision. Slightly fix/reorder fabric login stuff. Change to usage of isp_getrqentry for code clarity. Add some defensive dual bus assumptions. Various cleanups, etc...

static void isp_parse_status
__P((struct ispsoftc *, ispstatusreq_t *, ISP_SCSI_XFER_T *));
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..

Don't use NVRAM if are flagged as not to do so (I had a busted NVRAM setup which I couldn't edit that enabled SYNC mode but disabled disconnect/reconnect and wide!!). Fix delays after resets. BUS resets not done in isp_init anymore- relegated to OS specific outer layers. Fix a buglet where you can get in a loop for a NULL xs in the completion list in isp_intr.

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.

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.

Add in some defines that can disable fast posting. Add in code for Loop Up/Loop Down events that call into the outer layers as to what to do.

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.

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.

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.

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).

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..

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.

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..

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.

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.

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.

Clean up stupidity in the isp_handle_other_response function- indexes of queue entries have to be at least 16 bits now! If we're running a 2100 less than rev 5, turn off loop fairness (per Qlogic errata). Fix typo in checking against 2200 F/W revision. Slightly fix/reorder fabric login stuff. Change to usage of isp_getrqentry for code clarity. Add some defensive dual bus assumptions. Various cleanups, etc...

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.

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..

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.

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.

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.

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).

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.

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..

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.

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.

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.

Clean up stupidity in the isp_handle_other_response function- indexes of queue entries have to be at least 16 bits now! If we're running a 2100 less than rev 5, turn off loop fairness (per Qlogic errata). Fix typo in checking against 2200 F/W revision. Slightly fix/reorder fabric login stuff. Change to usage of isp_getrqentry for code clarity. Add some defensive dual bus assumptions. Various cleanups, etc...

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.

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.

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 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.

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..

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.

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..

Roll internal release tag. Print out if we're in a 64 bit PCI slot. Use fast memory timing NVRAM parameter. Clean up and fix establishment of default target parameters. Don't use NVRAM if are flagged as not to do so (I had a busted NVRAM setup which I couldn't edit that enabled SYNC mode but disabled disconnect/reconnect and wide!!). Fix delays after resets. BUS resets not done in isp_init anymore- relegated to OS specific outer layers. Fix a buglet where you can get in a loop for a NULL xs in the completion list in isp_intr. Add in some defines that can disable fast posting. Add in code for Loop Up/Loop Down events that call into the outer layers as to what to do.

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..

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.
