First of several commits as this driver is dusted off and maybe brought up to date. Principle changes for this reelase is to support 2K Port Login firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only come with the 2K Port Login firmware. The 2322 should now work- but we don't have firmware sets for it in ispfw (as the change to load 2K Port Login f/w hasn't been made- that f/w is so big it has to be loaded in more than one chunk). Other changes are the beginnings of cleaning up some long standing target mode issues. The next changes here will incorporate a lot of bug fixes from others. Finally, some copyright cleanup and attempts to make the parts of the driver that are FreeBSD specific start conforming more to FreeBSD style. MFC after: 1 month

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.

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.

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.

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.

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

Add get/set param ioctl support. Remove sim queue freezes for resource shortages. I've had too many strange race conditions where I freeze on a resource shortage but never get unfrozen. Consolidate the remaining sim queue freeze condition (for loopdown) into an inline with debug messages that allows us to track problems at ISP_LOGDEBUG0 level easier.

Distinguish between 2300 and 2312 chipsets- if only because the revisions on the chips have different meanings. Add more instrumentation plus ISP_GET_STATS and ISP_CLR_STATS ioctls.

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.

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

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. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

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.

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.

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

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.

Checkpoint of work in progress in cleaning up target mode. It actually seems to work well in RELENG_4. However, 5.X locking foo means that I'll have to do some quick redesign. Add ioctl handlers for ISP_GETROLE and ISP_SETROLE ioctls.

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.

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.

uint32_t dmaresult, handle;
a) clean up some declaration stuff (i.e., make more modern with respect to getting rid u_int for uint and so on). b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64. MFC after: 1 month

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.

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).

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

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.

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.

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).

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.

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).

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.

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

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.

if (IS_FC(isp)) {
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).

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).

isp_put_atio(isp, at, qe);
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. This is an awful lot of change, but target mode *still* isn't quite right. MFC after: 4 weeks

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.

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

isp_handle_platform_atio2(ispsoftc_t *isp, at2_entry_t *aep)
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 8Gb support (isp_2500). Fix a fair number of configuration and firmware loading bugs. Target mode support has received some serious attention to make it more usable and stable. Some backward compatible additions to CAM have been made that make target mode async events easier to deal with have also been put into place. Further refinement and better support for NP-IV (N-port Virtualization) is now in place. Code for release prior to RELENG_7 has been stripped away for code clarity.

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.

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.
2000-07-18 06:58:28 +00:00
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

In implementation of isp_handle_platform_notify_fc, for IN_ABORT_TASK, peel off a pending XPT_IMMED_NOTIFY and call xpt_done on it and hope that somebody upstream is listening. Make sure on final CTIO2s that we set residual correctly. These are absolutely crucial. Make sure we set relative offset for each CTIO2 based upon bytes we've already xferred. This is what the private adjunct datat to the original ATIO is. Note state of command so we can figure out where to find it if we get an ABORT from the firmware. Make sure we *always* set CAM_TAG_ACTION_VALID for ATIO2s. Make sure we keep track of the original lun.

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.

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 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.

isp_target_putback_atio(ccb);
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.

Accomodate old style XPT_IMMED_NOTIFY and XPT_NOTIFY_ACK so that we at least don't panic. We don't really support dual role mode (INITIATOR/TARGET) any more. We should but it's broken and will take a fair amount of effort to fix and correctly manage both initiator and target roles sharing the port database. So, for now, disallow it.

Add 8Gb support (isp_2500). Fix a fair number of configuration and firmware loading bugs. Target mode support has received some serious attention to make it more usable and stable. Some backward compatible additions to CAM have been made that make target mode async events easier to deal with have also been put into place. Further refinement and better support for NP-IV (N-port Virtualization) is now in place. Code for release prior to RELENG_7 has been stripped away for code clarity.

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 8Gb support (isp_2500). Fix a fair number of configuration and firmware loading bugs. Target mode support has received some serious attention to make it more usable and stable. Some backward compatible additions to CAM have been made that make target mode async events easier to deal with have also been put into place. Further refinement and better support for NP-IV (N-port Virtualization) is now in place. Code for release prior to RELENG_7 has been stripped away for code clarity.

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.

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.

Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

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 in a watchdog routine to catch cases where we've dropped the command. Apparently the f/w has finished the command, but somehow an interrupt is being lost. So, we just plain wedge when booting alphas. This is a general routine we've needed for a while.

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.

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

Change a bunch of debug messages about loop down/up conditions to ISP_LOGDEBUG0 level. Remove dead isp_relsim code. Change some internal flag stuff for efficiency. Complain vociferously if we try and use our FC scratch area while it's busy being used already (I mean, if we don't have solaris' ability to sleep as an interrupt thread which would allow us to just use a p/v semaphore, at least *say* when you've just borked yourself).

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.

Add get/set param ioctl support. Remove sim queue freezes for resource shortages. I've had too many strange race conditions where I freeze on a resource shortage but never get unfrozen. Consolidate the remaining sim queue freeze condition (for loopdown) into an inline with debug messages that allows us to track problems at ISP_LOGDEBUG0 level easier. Change a bunch of debug messages about loop down/up conditions to ISP_LOGDEBUG0 level. Remove dead isp_relsim code. Change some internal flag stuff for efficiency. Complain vociferously if we try and use our FC scratch area while it's busy being used already (I mean, if we don't have solaris' ability to sleep as an interrupt thread which would allow us to just use a p/v semaphore, at least *say* when you've just borked yourself). Add infrastructure to allow overrides of hard loopid && initiator id from boot variables. Fix the usual quota of silly bugs: + 'ktmature' needs to be per-instance. Argh. + When entering isp_watchdog, set intsok to zero, preserving old value to restore later. It's not nice to try and sleep from splsoftclock. + Fix tick overflow buglet in checking timeout value.

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 in a watchdog routine to catch cases where we've dropped the command. Apparently the f/w has finished the command, but somehow an interrupt is being lost. So, we just plain wedge when booting alphas. This is a general routine we've needed for a while.

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.

Make sure on final CTIO2s that we set residual correctly. These are absolutely crucial. Make sure we set relative offset for each CTIO2 based upon bytes we've already xferred. This is what the private adjunct datat to the original ATIO is. Note state of command so we can figure out where to find it if we get an ABORT from the firmware. Make sure we *always* set CAM_TAG_ACTION_VALID for ATIO2s. Make sure we keep track of the original lun. If se sent status (or we're otherwise done with the command), don't forget to free the adjunct structure.

In implementation of isp_handle_platform_notify_fc, for IN_ABORT_TASK, peel off a pending XPT_IMMED_NOTIFY and call xpt_done on it and hope that somebody upstream is listening. Make sure on final CTIO2s that we set residual correctly. These are absolutely crucial. Make sure we set relative offset for each CTIO2 based upon bytes we've already xferred. This is what the private adjunct datat to the original ATIO is. Note state of command so we can figure out where to find it if we get an ABORT from the firmware. Make sure we *always* set CAM_TAG_ACTION_VALID for ATIO2s. Make sure we keep track of the original lun. If se sent status (or we're otherwise done with the command), don't forget to free the adjunct structure.

Checkpoint of work in progress in cleaning up target mode. It actually seems to work well in RELENG_4. However, 5.X locking foo means that I'll have to do some quick redesign. Add ioctl handlers for ISP_GETROLE and ISP_SETROLE ioctls.

a) clean up some declaration stuff (i.e., make more modern with respect to getting rid u_int for uint and so on). b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64. MFC after: 1 month

a) clean up some declaration stuff (i.e., make more modern with respect to getting rid u_int for uint and so on). b) Turn back on 64 bit DAC support. Cheeze it a bit in that we have two DMA callback functions- one when we have bus_addr_t > 4 bits in width and the other which should be normal. Even Cheezier in that we turn off setting up DMA maps to be BUS_SPACE_MAXADDR if we're in ISP_TARGET_MODE. More work on this in a week or so. c) Tested under amd64 and 1MB DFLTPHYS, sparc64, i386 (PAE, but insufficient memory to really test > 4GB). LINT check under amd64. MFC after: 1 month

Then we rename cur_XXXX to actv_XXXX (these are the currently active settings) and the dev_XXX settings to goal_XXXX (these are the settings which we want cur_XXXX to converge to). This probably isn't entirely final as yet- but it's a lot closer to now being what it should be, including allowing camcontrol to actually set specific settings.

Allow fibre channel 'bus resets' to go through. Handle Loop Down/Loop Up events by freezing/unfreezing the simq- nice to have such control at this level! Do bus resets in attach layer (non-CAM defined code).

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 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.

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

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 8Gb support (isp_2500). Fix a fair number of configuration and firmware loading bugs. Target mode support has received some serious attention to make it more usable and stable. Some backward compatible additions to CAM have been made that make target mode async events easier to deal with have also been put into place. Further refinement and better support for NP-IV (N-port Virtualization) is now in place. Code for release prior to RELENG_7 has been stripped away for code clarity.

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

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.

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

Push things closer to path failover by implementing loop down and gone device timers and zombie state entries. There are tunables that can be used to select a number of parameters. loop_down_limit - how long to wait for loop to come back up before declaring all devices dead (default 300 seconds) gone_device_time- how long to wait for a device that has appeared to leave the loop or fabric to reappear (default 30 seconds) Internal tunables include (which should be externalized): quick_boot_time- how long to wait when booting for loop to come up change_is_bad- whether or not to accept devices with the same WWNN/WWPN that reappear at a different PortID as being the 'same' device. Keen students of some of the subtle issues here will ask how one can keep devices from being re-accepted at all (the answer is to set a gone_device_time to zero- that effectively would be the same thing).

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.

#ifdef ISP_TARGET_MODE
First of several commits as this driver is dusted off and maybe brought up to date. Principle changes for this reelase is to support 2K Port Login firmware. This allows us to support the 2322 (and 2422 4Gb) cards which only come with the 2K Port Login firmware. The 2322 should now work- but we don't have firmware sets for it in ispfw (as the change to load 2K Port Login f/w hasn't been made- that f/w is so big it has to be loaded in more than one chunk). Other changes are the beginnings of cleaning up some long standing target mode issues. The next changes here will incorporate a lot of bug fixes from others. Finally, some copyright cleanup and attempts to make the parts of the driver that are FreeBSD specific start conforming more to FreeBSD style. MFC after: 1 month

Add 8Gb support (isp_2500). Fix a fair number of configuration and firmware loading bugs. Target mode support has received some serious attention to make it more usable and stable. Some backward compatible additions to CAM have been made that make target mode async events easier to deal with have also been put into place. Further refinement and better support for NP-IV (N-port Virtualization) is now in place. Code for release prior to RELENG_7 has been stripped away for code clarity.

Make this an MP safe driver but also still be multi-release. Seems to work on RELENG_4 through -current and also on sparc64 now. There may still be some issues with the auto attach/detach code to sort out. MFC after: 3 days

Add 8Gb support (isp_2500). Fix a fair number of configuration and firmware loading bugs. Target mode support has received some serious attention to make it more usable and stable. Some backward compatible additions to CAM have been made that make target mode async events easier to deal with have also been put into place. Further refinement and better support for NP-IV (N-port Virtualization) is now in place. Code for release prior to RELENG_7 has been stripped away for code clarity.
