sys/dev: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

/*
* Driver for the Adaptec 'FSA' family of PCI/SCSI RAID adapters.
*/
Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver. Be the first on your block to low-level format unsuspecting drives that are part of an array! To enable this, add the 'aacp' device to your kernel config. MFC after: 3 days

o Move the cleanup of the fib maps into aac_free_commands() so as to retain symetry with aac_alloc_commans(). Since aac_alloc_commands() allocates fib maps and places them onto the fib lists, aac_free_commands() should reverse those operations. o Combine two ifs with the same body with an ||. o Switch from uintptr_t to uint32_t for fib map load operations. The target is a uint32_t so using this type for the map load call avoids an extra cast. uintptr_t should only be used when you need an "int sized the same as the machine's poitner size" which is not the case here. o Removed the commented out M_WAITOK flag in the allocation in aac_alloc_commands(). The kernel will only block in the allocator if it can grow the size of the kernel. This usually results in a page-out which could involve this aac device. Thus, sleeping here could deadlock the machine. Assuming this operation is occurring outside of attach time, we have enough fibs to operate anyway, so waiting for fibs to free up is okay if not optimal. o In aac_alloc_commands(), if we cannot dmamem_alloc additional fib space, free the fib map. o In aac_alloc_commands(), if we cannot create per-command dmamaps, don't lose track of the fib map that is mapping all of the commands that we have already released into the free pool. Instead, just cut out of the loop and modify aac_free_commands to not attempt to free maps that have not been allocated. o Don't use a magic number when pre-allocating fibs. o Use PAGE_SIZE to allocate in page sized chunks instead of an architecture specific constant.

Mega update to the aac driver. 1. Correctly handle commands initiated by the adapter. These commands are defered to a kthread responsible for their processing, then are properly returned to the controller. 2. Add/remove disk devices when notified by the card that a container was created/deleted/offline. 3. Implement crashdump functionality. 4. Support all ioctls needed for the management CLI to work.

While at it, make aac_if a pointer to the now const interface tables instead of copying them over to the softc (this alone already reduces the size of aac.ko on amd64 by ~1 KiB). - Remove redundant softc members. - Use DEVMETHOD_END. - Use NULL instead of 0 for pointers. - Remove redundant bzero(9)'ing of the softc. - Use pci_enable_busmaster(9) instead of duplicating it. - Remove redundant checking for PCIM_CMD_MEMEN (resource allocation will just fail). - Canonicalize the error messages in case of resource allocation failures. - Add support for using MSI instead of INTx, controllable via the tunable hw.aac.enable_msi (defaulting to on).

Mega busdma API commit. Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg. Lockfunc allows a driver to provide a function for managing its locking semantics while using busdma. At the moment, this is used for the asynchronous busdma_swi and callback mechanism. Two lockfunc implementations are provided: busdma_lock_mutex() performs standard mutex operations on the mutex that is specified from lockfuncarg. dftl_lock() is a panic implementation and is defaulted to when NULL, NULL are passed to bus_dma_tag_create(). The only time that NULL, NULL should ever be used is when the driver ensures that bus_dmamap_load() will not be deferred. Drivers that do not provide their own locking can pass busdma_lock_mutex,&Giant args in order to preserve the former behaviour. sparc64 and powerpc do not provide real busdma_swi functions, so this is largely a noop on those platforms. The busdma_swi on is64 is not properly locked yet, so warnings will be emitted on this platform when busdma callback deferrals happen.

Various cleanups: - Move the command timeout check from a separate repeating timeout to the kthread since the kthread is already running periodically. - Move printing the hardware print buffer to the kthread. - Properly shut down the kernel thread on detach. - Detach the child array devices on detach. - Don't issue a controller halt command on detach. Doing so requires a PCI reset to wake the controller back up. The driver can now be unloaded as long as CAM support is not enabled.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver. Be the first on your block to low-level format unsuspecting drives that are part of an array! To enable this, add the 'aacp' device to your kernel config. MFC after: 3 days

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it.

o Move the cleanup of the fib maps into aac_free_commands() so as to retain symetry with aac_alloc_commans(). Since aac_alloc_commands() allocates fib maps and places them onto the fib lists, aac_free_commands() should reverse those operations. o Combine two ifs with the same body with an ||. o Switch from uintptr_t to uint32_t for fib map load operations. The target is a uint32_t so using this type for the map load call avoids an extra cast. uintptr_t should only be used when you need an "int sized the same as the machine's poitner size" which is not the case here. o Removed the commented out M_WAITOK flag in the allocation in aac_alloc_commands(). The kernel will only block in the allocator if it can grow the size of the kernel. This usually results in a page-out which could involve this aac device. Thus, sleeping here could deadlock the machine. Assuming this operation is occurring outside of attach time, we have enough fibs to operate anyway, so waiting for fibs to free up is okay if not optimal. o In aac_alloc_commands(), if we cannot dmamem_alloc additional fib space, free the fib map. o In aac_alloc_commands(), if we cannot create per-command dmamaps, don't lose track of the fib map that is mapping all of the commands that we have already released into the free pool. Instead, just cut out of the loop and modify aac_free_commands to not attempt to free maps that have not been allocated. o Don't use a magic number when pre-allocating fibs. o Use PAGE_SIZE to allocate in page sized chunks instead of an architecture specific constant.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

Mega update to the aac driver. 1. Correctly handle commands initiated by the adapter. These commands are defered to a kthread responsible for their processing, then are properly returned to the controller. 2. Add/remove disk devices when notified by the card that a container was created/deleted/offline. 3. Implement crashdump functionality. 4. Support all ioctls needed for the management CLI to work.

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's.

Collapse sync fib locking into normal i/o locking. The former didn't protect the registers so it was trivially possible for a sync command and i/o command to fight each other and confuse the controller. Make the sync fib alloc/release functions inline and remove the somewhat worthless AAC_SYNC_LOCK_FORCE flag. Thanks to Adil Katchi for helping me to track this down in RELENG_4.

Major bugfixes for large memory and fast systems. aac.c: Re-arrange the interrupt handler to optimize the common case of the adapter interrupting us because one or more commands are complete, and do a read across the pci bus to ensure that all posted status writes are flushed. This should close a race that could cause command completion interrupts to be lost. Follow the spec a bit closer when filling out command structures. Enable the Fast Response feature to eliminate the need for the card to DMA successfull command completions back into host memory. Tell the controller how much physical memory we have. Without this there was a chance that our DMA regions would collide with the memory window used by the cache on the controller. The result would be massive data corruption. This seemed to mainly affect systems with >2GB of memory. Fix a few whitespace problems. aac_debug.c: Add an extra diagnostic when printing out commands. aac_disk.c: Add extra sanity checks. aacreg.h: Prepare for making this 64-bit clean by reducing the use of enumeration types in structures. Many thanks to Justin Gibbs for helping track these down.

Take the plunge and make this driver be INTR_FAST. This re-arranges the interrupt handler so that no locks are needed, and schedules the command completion routine with a taskqueue_fast. This also corrects the locking in the command thread and removes the need for operation flags. Simple load tests show that this is now considerably faster than FreeBSD 4.x in the SMP case when multiple i/o tasks are running.

Major bugfixes for large memory and fast systems. aac.c: Re-arrange the interrupt handler to optimize the common case of the adapter interrupting us because one or more commands are complete, and do a read across the pci bus to ensure that all posted status writes are flushed. This should close a race that could cause command completion interrupts to be lost. Follow the spec a bit closer when filling out command structures. Enable the Fast Response feature to eliminate the need for the card to DMA successfull command completions back into host memory. Tell the controller how much physical memory we have. Without this there was a chance that our DMA regions would collide with the memory window used by the cache on the controller. The result would be massive data corruption. This seemed to mainly affect systems with >2GB of memory. Fix a few whitespace problems. aac_debug.c: Add an extra diagnostic when printing out commands. aac_disk.c: Add extra sanity checks. aacreg.h: Prepare for making this 64-bit clean by reducing the use of enumeration types in structures.

This also corrects the locking in the command thread and removes the need for operation flags.

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver. Be the first on your block to low-level format unsuspecting drives that are part of an array! To enable this, add the 'aacp' device to your kernel config. MFC after: 3 days

This also corrects the locking in the command thread and removes the need for operation flags. Simple load tests show that this is now considerably faster than FreeBSD 4.x in the SMP case when multiple i/o tasks are running.

Bring aac out from under Giant: - the mutex aac_io_lock protects the main codepaths which handle queues and hardware registers. Only one acquire/release is done in the top-half and the taskqueue. This mutex also applies to the userland command path and CAM data path. - Move the taskqueue to the new Giant-free version. - Register the disk device with DISKFLAG_NOGIANT so the top-half processing runs without Giant. - Move the dynamic command allocator to the worker thread to avoid locking issues with bus_dmamem_alloc().

If a command has to be deferred because there are no more resources for it on the card, unmap it first. This allows it to be picked up properly when the queue gets kicked again. This was the root problem for the lost command (i.e. stuck in getblk/vinvalb) problem. While here, panic if commands don't map correctly instead of just silently ignoring the problem and dropping command. Also slow down the dynamic allocation of new commands. It should be safe to go back into the aac waters. Thanks to everyone who suffered through this and provided good feedback.

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface.

This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's.

Various cleanups: - Move the command timeout check from a separate repeating timeout to the kthread since the kthread is already running periodically. - Move printing the hardware print buffer to the kthread. - Properly shut down the kernel thread on detach. - Detach the child array devices on detach. - Don't issue a controller halt command on detach. Doing so requires a PCI reset to wake the controller back up. The driver can now be unloaded as long as CAM support is not enabled.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver. Be the first on your block to low-level format unsuspecting drives that are part of an array! To enable this, add the 'aacp' device to your kernel config. MFC after: 3 days

Rename the kthread_xxx (e.g. kthread_create()) calls to kproc_xxx as they actually make whole processes. Thos makes way for us to add REAL kthread_create() and friends that actually make theads. it turns out that most of these calls actually end up being moved back to the thread version when it's added. but we need to make this cosmetic change first.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

Bring aac out from under Giant: - the mutex aac_io_lock protects the main codepaths which handle queues and hardware registers. Only one acquire/release is done in the top-half and the taskqueue. This mutex also applies to the userland command path and CAM data path. - Move the taskqueue to the new Giant-free version. - Register the disk device with DISKFLAG_NOGIANT so the top-half processing runs without Giant. - Move the dynamic command allocator to the worker thread to avoid locking issues with bus_dmamem_alloc(). This gives about 20% improvement in most of my benchmarks.

Use time_uptime for timing commands instead of time_second. This is a bit risky because the "current time" is supposed to be fed to the card during initialization, and the current time is supposed to be put into each command that is sent to the card. Hopefully either the card doesn't actually care about the timestamps, or it doesn't care about the absolute values so long and the relative values are consistent. Not an MFC candidate until more thorough testing can be done.

Major bugfixes for large memory and fast systems. aac.c: Re-arrange the interrupt handler to optimize the common case of the adapter interrupting us because one or more commands are complete, and do a read across the pci bus to ensure that all posted status writes are flushed. This should close a race that could cause command completion interrupts to be lost. Follow the spec a bit closer when filling out command structures. Enable the Fast Response feature to eliminate the need for the card to DMA successfull command completions back into host memory. Tell the controller how much physical memory we have. Without this there was a chance that our DMA regions would collide with the memory window used by the cache on the controller. The result would be massive data corruption. This seemed to mainly affect systems with >2GB of memory. Fix a few whitespace problems. aac_debug.c: Add an extra diagnostic when printing out commands. aac_disk.c: Add extra sanity checks. aacreg.h: Prepare for making this 64-bit clean by reducing the use of enumeration types in structures. Many thanks to Justin Gibbs for helping track these down.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver.

Major bugfixes for large memory and fast systems. aac.c: Re-arrange the interrupt handler to optimize the common case of the adapter interrupting us because one or more commands are complete, and do a read across the pci bus to ensure that all posted status writes are flushed. This should close a race that could cause command completion interrupts to be lost. Follow the spec a bit closer when filling out command structures. Enable the Fast Response feature to eliminate the need for the card to DMA successfull command completions back into host memory. Tell the controller how much physical memory we have. Without this there was a chance that our DMA regions would collide with the memory window used by the cache on the controller. The result would be massive data corruption. This seemed to mainly affect systems with >2GB of memory. Fix a few whitespace problems. aac_debug.c: Add an extra diagnostic when printing out commands. aac_disk.c: Add extra sanity checks. aacreg.h: Prepare for making this 64-bit clean by reducing the use of enumeration types in structures. Many thanks to Justin Gibbs for helping track these down.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

Begin support for 64-bit address support and workarounds for newer cards: - Add data structuress for doing 64-bit scatter/gather - Move busdma tag creations around so that only the parent is created in aac_pci.c. - Retrieve the capabilities word from the firmware before setting up command structures and tags. This allows the driver to decide whether to do 64-bit commands, and if work-arounds are needed for systems with >2GB of RAM. - Only enable the SCSI passthrough if it's enabled in the capabilities word in the firmware. This should fix problems with the 2120S and 2200S cards in systems with more than 2GB of RAM. Full 64-bit support is forthcoming. MFC-After: 1 week

/*
Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

If a command has to be deferred because there are no more resources for it on the card, unmap it first. This allows it to be picked up properly when the queue gets kicked again. This was the root problem for the lost command (i.e. stuck in getblk/vinvalb) problem. While here, panic if commands don't map correctly instead of just silently ignoring the problem and dropping command. Also slow down the dynamic allocation of new commands. It should be safe to go back into the aac waters. Thanks to everyone who suffered through this and provided good feedback.

Major bugfixes for large memory and fast systems. aac.c: Re-arrange the interrupt handler to optimize the common case of the adapter interrupting us because one or more commands are complete, and do a read across the pci bus to ensure that all posted status writes are flushed. This should close a race that could cause command completion interrupts to be lost. Follow the spec a bit closer when filling out command structures. Enable the Fast Response feature to eliminate the need for the card to DMA successfull command completions back into host memory. Tell the controller how much physical memory we have. Without this there was a chance that our DMA regions would collide with the memory window used by the cache on the controller. The result would be massive data corruption.

Use time_uptime for timing commands instead of time_second. This is a bit risky because the "current time" is supposed to be fed to the card during initialization, and the current time is supposed to be put into each command that is sent to the card. Hopefully either the card doesn't actually care about the timestamps, or it doesn't care about the absolute values so long and the relative values are consistent. Not an MFC candidate until more thorough testing can be done.

* Send a synchronous command to the controller and wait for a result.
Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

Use time_uptime for timing commands instead of time_second. This is a bit risky because the "current time" is supposed to be fed to the card during initialization, and the current time is supposed to be put into each command that is sent to the card. Hopefully either the card doesn't actually care about the timestamps, or it doesn't care about the absolute values so long and the relative values are consistent. Not an MFC candidate until more thorough testing can be done.

Begin support for 64-bit address support and workarounds for newer cards: - Add data structuress for doing 64-bit scatter/gather - Move busdma tag creations around so that only the parent is created in aac_pci.c. - Retrieve the capabilities word from the firmware before setting up command structures and tags. This allows the driver to decide whether to do 64-bit commands, and if work-arounds are needed for systems with >2GB of RAM. - Only enable the SCSI passthrough if it's enabled in the capabilities word in the firmware. This should fix problems with the 2120S and 2200S cards in systems with more than 2GB of RAM. Full 64-bit support is forthcoming. MFC-After: 1 week

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface.

This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

Correctly wrap the producer queue index when dequeuing commands. This wasn't a problem for command responses since we rarely ever filled the queue. However, adapter-initiated commands have a much smaller queue and could tickle this bug. It's possible that this might fix the recently reported problems with the aac-2120s, though I haven't been able to reproduce the problem locally. MFC-After: 1 day

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Major bugfixes for large memory and fast systems. aac.c: Re-arrange the interrupt handler to optimize the common case of the adapter interrupting us because one or more commands are complete, and do a read across the pci bus to ensure that all posted status writes are flushed. This should close a race that could cause command completion interrupts to be lost. Follow the spec a bit closer when filling out command structures. Enable the Fast Response feature to eliminate the need for the card to DMA successfull command completions back into host memory. Tell the controller how much physical memory we have. Without this there was a chance that our DMA regions would collide with the memory window used by the cache on the controller. The result would be massive data corruption. This seemed to mainly affect systems with >2GB of memory. Fix a few whitespace problems. aac_debug.c: Add an extra diagnostic when printing out commands. aac_disk.c: Add extra sanity checks. aacreg.h: Prepare for making this 64-bit clean by reducing the use of enumeration types in structures. Many thanks to Justin Gibbs for helping track these down.

Use time_uptime for timing commands instead of time_second. This is a bit risky because the "current time" is supposed to be fed to the card during initialization, and the current time is supposed to be put into each command that is sent to the card. Hopefully either the card doesn't actually care about the timestamps, or it doesn't care about the absolute values so long and the relative values are consistent. Not an MFC candidate until more thorough testing can be done.

If the timeout handler runs and notices that commands are timed out, check the firmware status register on the card to see if the firmware is still running. There is no way to recover from this, but at least it can give a hint as whether the car has crashed (which happens all too often). MFC after: 3 days

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

SVN rev 188743 modified aac_rx_get_fwstatus to use the AAC_RX_OMR0 register instead of AAC_RX_FWSTATUS, as that is the way it's done in Adaptec's vendor driver and in the Linux drivers. (The same applies to aac_rkt_get_fwstatus as well.) However, a concern has been raised about the compatibility of this change and old hardware / firmware versions. In the absense of specific information, revert to the original behaviour if the firmware does not support the "New comm." interface. Users of old cards or firmware haven't reported the problems that are potentially solved by switching to OMR0.

Begin support for 64-bit address support and workarounds for newer cards: - Add data structuress for doing 64-bit scatter/gather - Move busdma tag creations around so that only the parent is created in aac_pci.c. - Retrieve the capabilities word from the firmware before setting up command structures and tags. This allows the driver to decide whether to do 64-bit commands, and if work-arounds are needed for systems with >2GB of RAM. - Only enable the SCSI passthrough if it's enabled in the capabilities word in the firmware.

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface.

This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's.

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver. Be the first on your block to low-level format unsuspecting drives that are part of an array! To enable this, add the 'aacp' device to your kernel config. MFC after: 3 days

Calling RequestSupplementAdapterInfo before RequestAdapterInfo appears to trip a bug causing the latter to return a zeroed struct aac_adapter_info. This causes two issues. One is cosmetic only -- a verbose boot prints information about the controller, and shows all zero: aac0: Unknown processor 0MHz, 0MB memory (0MB cache, 0MB execution), unknown battery platform The second problem is that the firmware version information is stored away for aac_rev_check, for userland tools (like aaccli) to query via the FSACTL_MINIPORT_REV_CHECK and FSACTL_LNX_MINIPORT_REV_CHECK ioctls. When aaccli encounters this issue it prints Command Error: <The current AFAAPI.DLL is too old to work with the current controller software.> Move the RequestSupplementAdapterInfo call after RequestAdapterInfo, which seems to fix both problems.

- Make tables, device ID strings etc const. This includes #ifdef'ing 0 aac_command_status_table, which is actually unused since r111532. While at it, make aac_if a pointer to the now const interface tables instead of copying them over to the softc (this alone already reduces the size of aac.ko on amd64 by ~1 KiB). - Remove redundant softc members. - Use DEVMETHOD_END. - Use NULL instead of 0 for pointers. - Remove redundant bzero(9)'ing of the softc. - Use pci_enable_busmaster(9) instead of duplicating it. - Remove redundant checking for PCIM_CMD_MEMEN (resource allocation will just fail). - Canonicalize the error messages in case of resource allocation failures. - Add support for using MSI instead of INTx, controllable via the tunable hw.aac.enable_msi (defaulting to on).

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Add functionality and fix bugs so the driver will work with soon-to-be released management apps. 1. Implement poll(). This will check for queued aif's so that a subsequent ioctl call to retrieve the next aif will not block. 2. Don't catch signals when sleeping on a fib sent from userland. This causes a race and panic due to the pthread context switcher waking up the tsleep at inopportune times. 3. Fix some whitespace nits. MFC after: 3 days

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Use time_uptime for timing commands instead of time_second. This is a bit risky because the "current time" is supposed to be fed to the card during initialization, and the current time is supposed to be put into each command that is sent to the card. Hopefully either the card doesn't actually care about the timestamps, or it doesn't care about the absolute values so long and the relative values are consistent. Not an MFC candidate until more thorough testing can be done.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command. This could cause us to lose the deferred command. - Use diskerr() to report I/O errors. - Don't bail if the AdapterInfo structure is the wrong size. Some variation seems to be normal. We need to improve our handing of 2.x firmware sets. - Improve some comments in an attempt to try to make things clearer. - Restructure to avoid some warnings.

Put the linux compat ioctl interface on death row. Add FreeBSD definitions of all of the ioctls, plus round out all ioctl definitions to match what exists for linux. Allow ioctls to be called through either the native or linux interface, though no apps exist (yet) that can take advantage of native calling.

Major bugfix and minor update. This should resolve the current issues with the driver locking up under load. - Restructure so that we use a static pool of commands/FIBs, rather than allocating them in clusters. The cluster allocation just made things more complicated, and allowed us to waste more memory in peak load situations. - Make queueing macros more like my other drivers. This adds queue stats for free. Add some debugging to take advantage of this. - Reimplement the periodic timeout scan. Kick the interrupt handler and the start routine every scan as well, just to be safe. Track busy commands properly. - Bring resource cleanup into line with resource allocation. We should now clean up correctly after a failed probe/unload/etc. - Try to start new commands when old ones are completed. We weren't doing this before, which could lead to deadlock when the controller was full. - Don't try to build a new command if we have found a deferred command.

Mega update to the aac driver. 1. Correctly handle commands initiated by the adapter.

Add/remove disk devices when notified by the card that a container was created/deleted/offline. 3. Implement crashdump functionality. 4. Support all ioctls needed for the management CLI to work.

Mega Update to the aac driver to support a whole new family of cards and the modified interface that they use. Changes include: - Register a different interrupt handler for the new interface. This one is INTR_MPSAFE, not INTR_FAST, and directly processes completions and AIFs. - Add an event registration and callback mechanism for the ioctl and CAM modules can know when a resource shortage clears. This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

This condition was previously fatal in CAM due to programming oversights. - Fix locking to play better with newbus. - Provide access methods for talking to cards with the NEWCOMM interface. - Fix up the CAM module to be better suited for dealing with newer firmware on the PERC Si/Di series that requires talking to plain SCSI via aac. - Add a whole slew of new PCI Id's. Thanks to Adaptec for providing an initial version of this work and for answering countless questions about it. There are still some rough edges in this, but it works well enough to commit and test for now. Obtained from: Adaptec, Inc.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver. Be the first on your block to low-level format unsuspecting drives that are part of an array! To enable this, add the 'aacp' device to your kernel config. MFC after: 3 days

Various cleanups: - Move the command timeout check from a separate repeating timeout to the kthread since the kthread is already running periodically. - Move printing the hardware print buffer to the kthread. - Properly shut down the kernel thread on detach. - Detach the child array devices on detach. - Don't issue a controller halt command on detach. Doing so requires a PCI reset to wake the controller back up. The driver can now be unloaded as long as CAM support is not enabled.

Collapse sync fib locking into normal i/o locking. The former didn't protect the registers so it was trivially possible for a sync command and i/o command to fight each other and confuse the controller. Make the sync fib alloc/release functions inline and remove the somewhat worthless AAC_SYNC_LOCK_FORCE flag. Thanks to Adil Katchi for helping me to track this down in RELENG_4.

Add a CAM interface to the aac driver. This is useful in case you should ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper to your high-end RAID controller. The interface to the arrays is still via the block interface; this merely provides a way to circumvent the RAID functionality and access the SCSI buses directly. Note that for somewhat obvious reasons, hard drives are not exposed to the da driver through this interface, though you can still talk to them via the pass driver. Be the first on your block to low-level format unsuspecting drives that are part of an array! To enable this, add the 'aacp' device to your kernel config. MFC after: 3 days

Various cleanups: - Move the command timeout check from a separate repeating timeout to the kthread since the kthread is already running periodically. - Move printing the hardware print buffer to the kthread. - Properly shut down the kernel thread on detach. - Detach the child array devices on detach. - Don't issue a controller halt command on detach. Doing so requires a PCI reset to wake the controller back up. The driver can now be unloaded as long as CAM support is not enabled.
