Add a driver for the new LSI MegaRAID SAS controller family. The 'MFI' name is derived from the phrase 'MegaRAID Firmware Interface' used by LSI. This driver provides a block interface to logical disks on the card and a minimal management device. It is MPSAFE, INTR_FAST, and 64-bit capable. Thanks to Dell for providing hardware to test with and IronPort for sponsoring the work. Sponsored by: Dell, Ironport MFC After: 3 days

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

Fixes queuing issues where mfi_release_command blindly sets the cm_flags = 0 without first removing the command from the relavent queue. This was causing panics in the queue functions which check to ensure a command is not on another queue. Fixed some cases where the error from mfi_mapcmd was lost and where the command was never released / dequeued in error cases. Ensure that all failures to mfi_mapcmd are logged. Fixed possible null pointer exception in mfi_aen_setup if mfi_get_log_state failed. Fixed mfi_parse_entries & mfi_aen_setup not returning possible errors. Corrected MFI_DUMP_CMDS calls with invalid vars SC vs sc. Commands which have timed out now set cm_error to ETIMEDOUT and call mfi_complete which prevents them getting stuck in the busy queue forever. Fixed possible use of NULL pointer in mfi_tbolt_get_cmd. Changed output formats to be more easily recognisable when debugging. Optimised mfi_cmd_pool_tbolt cleanup. Made information about driver limiting commands always display as for modern cards this can be severe. Fixed mfi_tbolt_alloc_cmd out of memory case which previously didnt return an error. Added malloc checks for request_desc_pool including free when subsiquent errors are detected. Fixed overflow error in SIMD reply descriptor check. Fixed tbolt_cmd leak in mfi_build_and_issue_cmd if there's an error during IO build. Elimintated double checks on sc->mfi_aen_cm & sc->mfi_map_sync_cm in mfi_shutdown. Move local hdr calculation after error check in mfi_aen_complete. Fixed wakeup on NULL in mfi_aen_complete. Fixed mfi_aen_cm cleanup in mfi_process_fw_state_chg_isr not checking if it was NULL. Changed mfi_alloc_commands to error if bus_dmamap_create fails. Previously we would try to continue with the number of allocated commands but lots of places in the driver assume sc->mfi_max_fw_cmds is whats available so its unsafe to do this without lots of changes. Removed mfi_total_cmds as its no longer used due the above change. Corrected mfi_tbolt_alloc_cmd to return ENOMEM where appropriate. Fixed timeouts actually firing at double what they should. Setting hw.mfi.max_cmds=-1 now configures to use the controller max. A few style (9) fixes e.g. braced single line conditions and double blank lines Cleaned up queuing macros Removed invalid queuing tests for multiple queues Trap and deal with errors when doing sends in mfi_data_cb Refactored frame sending into one method with error checking of the return code so we can ensure commands aren't left on the queue after error. This ensures that mfi_mapcmd & mfi_data_cb leave the queue in a valid state. Refactored how commands are cleaned up, mfi_release_command now ensures that all queues and command state is maintained in a consistent state. Prevent NULL pointer use in mfi_tbolt_complete_cmd Fixed use of NULL sc->mfi_map_sync_cm in wakeup Added defines to help with output of mfi_cmd and header flags. Fixed mfi_tbolt_init_MFI_queue invalidating cm_index of the acquired mfi_cmd. Reset now reinitialises sync map as well as AEN. Fixed possible use of NULL pointer in mfi_build_and_issue_cmd Fixed mfi_tbolt_init_MFI_queue call to mfi_process_fw_state_chg_isr causing panic on failure. Ensure that tbolt cards always initialise next_host_reply_index and free_host_reply_index (based off mfi_max_fw_cmds) on both startup and reset as per the linux driver. Fixed mfi_tbolt_complete_cmd not acknowledging unknown commands so it didn't clear the controller. Prevent locks from being dropped and re-acquired in the following functions which was allowing multiple threads to enter critical methods such as mfi_tbolt_complete_cmd & mfi_process_fw_state_chg_isr:- * mfi_tbolt_init_MFI_queue * mfi_aen_complete / mfi_aen_register * mfi_tbolt_sync_map_info * mfi_get_log_state * mfi_parse_entries The locking for these functions was promoting to higher level methods. This also fixed MFI_LINUX_SET_AEN_2 which was already acquiring the lock, so would have paniced for recursive lock. This also required changing malloc of ld_sync in mfi_tbolt_sync_map_info to M_NOWAIT which can hence now fail but this was already expected as its return was being tested. Removed the assignment of cm_index in mfi_tbolt_init_MFI_queue which breaks the world if the cmd returned by mfi_dequeue_free isn't the first cmd. Fixed locking in mfi_data_cb, this is an async callback from bus_dmamap_load which could hence be called after the caller has dropped the lock. If we don't have the lock we aquire it and ensure we unlock before returning. Fixed locking mfi_comms_init when mfi_dequeue_free fails. Fixed mfi_build_and_issue_cmd not returning tbolt cmds aquired to the pool on error. Fixed mfi_abort not dropping the io lock when mfi_dequeue_free fails. Added hw.mfi.polled_cmd_timeout sysctl that enables tuning of polled timeouts. This shouldn't be reduced below 50 seconds as its used for firmware patching which can take quite some time. Added hw.mfi.fw_reset_test sysctl which is avaliable when compiled with MFI_DEBUG and allows the testing of controller reset that was provoking a large number of the issues encountered here.

Ensure that tbolt cards always initialise next_host_reply_index and free_host_reply_index (based off mfi_max_fw_cmds) on both startup and reset as per the linux driver. Fixed mfi_tbolt_complete_cmd not acknowledging unknown commands so it didn't clear the controller. Prevent locks from being dropped and re-acquired in the following functions which was allowing multiple threads to enter critical methods such as mfi_tbolt_complete_cmd & mfi_process_fw_state_chg_isr:- * mfi_tbolt_init_MFI_queue * mfi_aen_complete / mfi_aen_register * mfi_tbolt_sync_map_info * mfi_get_log_state * mfi_parse_entries The locking for these functions was promoting to higher level methods. This also fixed MFI_LINUX_SET_AEN_2 which was already acquiring the lock, so would have paniced for recursive lock. This also required changing malloc of ld_sync in mfi_tbolt_sync_map_info to M_NOWAIT which can hence now fail but this was already expected as its return was being tested. Removed the assignment of cm_index in mfi_tbolt_init_MFI_queue which breaks the world if the cmd returned by mfi_dequeue_free isn't the first cmd. Fixed locking in mfi_data_cb, this is an async callback from bus_dmamap_load which could hence be called after the caller has dropped the lock. If we don't have the lock we aquire it and ensure we unlock before returning. Fixed locking mfi_comms_init when mfi_dequeue_free fails. Fixed mfi_build_and_issue_cmd not returning tbolt cmds aquired to the pool on error. Fixed mfi_abort not dropping the io lock when mfi_dequeue_free fails. Added hw.mfi.polled_cmd_timeout sysctl that enables tuning of polled timeouts. This shouldn't be reduced below 50 seconds as its used for firmware patching which can take quite some time. Added hw.mfi.fw_reset_test sysctl which is avaliable when compiled with MFI_DEBUG and allows the testing of controller reset that was provoking a large number of the issues encountered here.

Add in a couple of things: - In the ioctl path let command get queued up and return when complete _without_ blocking the driving waiting for the response. This way the driver doesn't "lock up" for ~30s during a flash command. Submitted by scottl. - Add a guard so that if a DCMD of 0 is sent down the ioctl path don't send it to the controller. Return with a status of OK. This is a little strange since MegaCli doesn't seem to like something and will issue some DCMD of 0. This doesn't happen under Linux. So the emulation needs to be improved but I'm not sure what. Another strange thing is that when a DCMD of 0 gets issued under i386 the controller returns OK but in amd64 the context is messed up. - Add a guard so the context has to be with-in the legal limit so we get a reasonable error assertion versus random panic. It's going to be a challenge to figure out why MegaCli is not totally happy and then sends some bogus commands. This means that flashing firmware via the Linux tool won't work since it generates a DCMD of 0 when it should be opening the firmware for a flash update. Without this problem flashing works fine. This means there is no publicly available tool to upgrade the RAID firmware under FreeBSD right now. I plan to MFC all of the mfi changes to 6.X shortly. This might not include the SCSI pass-through changes. Submitted by: scottl Reviewed by: scottl MFC after: 3 days

- Extend the prior commit to use the generic SCSI command building function use that for JBOD and Thunderbolt disk write command. Now we only have one implementation in mfi. - Fix dumping on Thunderbolt cards. Polled IO commands do not seem to be normally acknowledged by changing cmd_status to MFI_STAT_OK. In order to get acknowledgement of the IO is complete, the Thunderbolt command queue needs to be run through. I added a flag MFI_CMD_SCSI to indicate this command is being polled and to complete the Thunderbolt wrapper and indicate the result. This flag needs to be set in the JBOD case in case if that us using Thunderbolt card. When in the polling loop check for completed commands. - Remove mfi_tbolt_is_ldio and just do the check when needed. - Fix an issue when attaching of disk device happens when a device is already scheduled to be attached but hasn't attached. - add a tunable to allow raw disk attachment to CAM via: hw.mfi.allow_cam_disk_passthrough=1 - fixup aborting of commands (AEN and LD state change). Use a generic abort function and only wait the command being aborted not both. Thunderbolt cards don't seem to abort commands so the abort times out.

Add in a bunch of things to the mfi driver: - Linux ioctl support, with the other Linux changes MegaCli will run if you mount linprocfs & linsysfs then set sysctl compat.linux.osrelease=2.6.12 or similar. This works on i386. It should work on amd64 but not well tested yet. StoreLib may or may not work. Remember to kldload mfi_linux. - Add in AEN (Async Event Notification) support so we can get messages from the firmware when something happens. Not all messages are in defined in event detail. Use event_log to try to figure out what happened. - Try to implement something like SIGIO for StoreLib. Since mrmonitor doesn't work right I can't fully test it. StoreLib works best with the rh9 base. In theory mrmonitor isn't needed due to native driver support of AEN :-) Now we can configure and monitor the RAID better. Submitted by: IronPort Systems.

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

Add a driver for the new LSI MegaRAID SAS controller family. The 'MFI' name is derived from the phrase 'MegaRAID Firmware Interface' used by LSI. This driver provides a block interface to logical disks on the card and a minimal management device. It is MPSAFE, INTR_FAST, and 64-bit capable.

#define MFI_FLAGS_SKINNY (1<<7)
#define MFI_FLAGS_TBOLT (1<<8)
Add a tunable "hw.mfi.mrsas_enable" to allow mfi(4) to drop priority and allow mrsas(4) from LSI to attach to newer LSI cards that are support by mrsas(4). If mrsas(4) is not loaded into the system at boot then mfi(4) will always attach. If a modified mrsas(4) is loaded in the system. That modification is return "-30" in it's probe since that is between BUS_PROBE_DEFAULT and BUS_PROBE_LOW_PRIORITY. This option is controller by a new probe flag "MFI_FLAGS_MRSAS" in mfi_ident that denotes cards that should work with mrsas(4). New entries that should have this option. This is the first step to get mrsas(4) checked into FreeBSD and to avoid collision with people that use mrsas(4) from LSI. Since mfi(4) takes priority, then mrsas(4) users need to rebuild GENERIC. Using the .disabled="1" method doesn't work since that blocks attaching and the probe gave it to mfi(4). Discussed with: LSI (Kashyap Desai)

#define MFI_FLAGS_MRSAS (1<<9)
Add support for MegaRAID Fury cards. The main change needed to boot from a 9341-4i controller was to ensure that scatter/gather lists are ended with an end-of-list marker. Both the mrsas and Linux megaraid_sas drivers use this marker with Invader cards as well, so we do the same thing, though it is apparently not strictly necessary.

First fix pr 167226: ThunderBolt cannot read sector >= 2^32 or 2^21 with supplied patch. Second the bigger change, fix RAID operation on ThunderBolt base card such as physically removing a disk from a RAID and replacing it. The current situation is the RAID firmware effectively hangs waiting for an acknowledgement from the driver. This is due to the firmware support of the driver actually accessing the RAID from under the firmware. This is an interesting feature that the FreeBSD driver does not use. However, when the firmare detects the driver has attached it then expects the driver will synchronize LD's with the firmware. If the driver does not sync. then the management part of the firmware will hang waiting for it so a pulled driver will listed as still there. The fix for this problem isn't extremely difficult. However, figuring out why some of the code was the way it was and then redoing it was involved. Not have a spec. made it harder to try to figure out. The existing driver would send a MFI_DCMD_LD_MAP_GET_INFO command in write mode to acknowledge a LD state change. In read mode it gets the RAID map from the firmware. The FreeBSD driver doesn't do that currently. It could be added in the future with the appropriate structures. To simplify things, get the current LD state and then build the MFI_DCMD_LD_MAP_GET_INFO/write command so that it sends an acknowledgement for each LD. The map would probably state which LD's changed so then the driver could probably just acknowledge the LD's that changed versus all. This doesn't seem to be a problem. When a MFI_DCMD_LD_MAP_GET_INFO/write command is sent to the firmware, it will complete later when a change to the LD's happen. So it is very much like an AEN command returning when something happened. When the MFI_DCMD_LD_MAP_GET_INFO/write command completes, we refire the sync'ing of the LD state. This needs to be done in as an event so that MFI_DCMD_LD_GET_LIST can wait for that command to complete before issuing the MFI_DCMD_LD_MAP_GET_INFO/write. The prior code didn't use the call-back function and tried to intercept the MFI_DCMD_LD_MAP_GET_INFO/write command when processing an interrupt. This added a bunch of code complexity to the interrupt handler. Using the call-back that is done for other commands got rid of this need. So the interrupt handler is greatly simplified. It seems that even commands that shouldn't be acknowledged end up in the interrupt handler. To deal with this, code was added to check to see if a command is in the busy queue or not. This might have contributed to the interrupt storm happening without MSI enabled on these cards. Note that MFI_DCMD_LD_MAP_GET_INFO/read returns right away. It would be interesting to see what other complexity could be removed from the ThunderBolt driver that really isn't needed in our mode of operation. Letting the RAID firmware do all of the I/O to disks is a lot faster since it can use its caches. It greatly simplifies what the driver has to do and potential bugs if the driver and firmware are not in sync. Simplify the aen_abort/cm_map_abort and put it in the softc versus in the command structure. This should get merged to 9 before the driver is merged to 8.

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

- Extend the prior commit to use the generic SCSI command building function use that for JBOD and Thunderbolt disk write command. Now we only have one implementation in mfi. - Fix dumping on Thunderbolt cards. Polled IO commands do not seem to be normally acknowledged by changing cmd_status to MFI_STAT_OK. In order to get acknowledgement of the IO is complete, the Thunderbolt command queue needs to be run through. I added a flag MFI_CMD_SCSI to indicate this command is being polled and to complete the Thunderbolt wrapper and indicate the result. This flag needs to be set in the JBOD case in case if that us using Thunderbolt card. When in the polling loop check for completed commands. - Remove mfi_tbolt_is_ldio and just do the check when needed. - Fix an issue when attaching of disk device happens when a device is already scheduled to be attached but hasn't attached. - add a tunable to allow raw disk attachment to CAM via: hw.mfi.allow_cam_disk_passthrough=1 - fixup aborting of commands (AEN and LD state change). Use a generic abort function and only wait the command being aborted not both. Thunderbolt cards don't seem to abort commands so the abort times out.

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported.

/* Virtual address of reply Frame Pool */
struct mfi_mpi2_reply_header* reply_frame_pool;
First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

Second the bigger change, fix RAID operation on ThunderBolt base card such as physically removing a disk from a RAID and replacing it. The current situation is the RAID firmware effectively hangs waiting for an acknowledgement from the driver. This is due to the firmware support of the driver actually accessing the RAID from under the firmware. This is an interesting feature that the FreeBSD driver does not use. However, when the firmare detects the driver has attached it then expects the driver will synchronize LD's with the firmware. If the driver does not sync. then the management part of the firmware will hang waiting for it so a pulled driver will listed as still there. The fix for this problem isn't extremely difficult. However, figuring out why some of the code was the way it was and then redoing it was involved. Not have a spec. made it harder to try to figure out. The existing driver would send a MFI_DCMD_LD_MAP_GET_INFO command in write mode to acknowledge a LD state change. In read mode it gets the RAID map from the firmware. The FreeBSD driver doesn't do that currently. It could be added in the future with the appropriate structures. To simplify things, get the current LD state and then build the MFI_DCMD_LD_MAP_GET_INFO/write command so that it sends an acknowledgement for each LD. The map would probably state which LD's changed so then the driver could probably just acknowledge the LD's that changed versus all. This doesn't seem to be a problem. When a MFI_DCMD_LD_MAP_GET_INFO/write command is sent to the firmware, it will complete later when a change to the LD's happen. So it is very much like an AEN command returning when something happened. When the MFI_DCMD_LD_MAP_GET_INFO/write command completes, we refire the sync'ing of the LD state. This needs to be done in as an event so that MFI_DCMD_LD_GET_LIST can wait for that command to complete before issuing the MFI_DCMD_LD_MAP_GET_INFO/write. The prior code didn't use the call-back function and tried to intercept the MFI_DCMD_LD_MAP_GET_INFO/write command when processing an interrupt. This added a bunch of code complexity to the interrupt handler. Using the call-back that is done for other commands got rid of this need. So the interrupt handler is greatly simplified. It seems that even commands that shouldn't be acknowledged end up in the interrupt handler. To deal with this, code was added to check to see if a command is in the busy queue or not. This might have contributed to the interrupt storm happening without MSI enabled on these cards. Note that MFI_DCMD_LD_MAP_GET_INFO/read returns right away. It would be interesting to see what other complexity could be removed from the ThunderBolt driver that really isn't needed in our mode of operation. Letting the RAID firmware do all of the I/O to disks is a lot faster since it can use its caches. It greatly simplifies what the driver has to do and potential bugs if the driver and firmware are not in sync. Simplify the aen_abort/cm_map_abort and put it in the softc versus in the command structure. This should get merged to 9 before the driver is merged to 8.

- Extend the prior commit to use the generic SCSI command building function use that for JBOD and Thunderbolt disk write command. Now we only have one implementation in mfi. - Fix dumping on Thunderbolt cards. Polled IO commands do not seem to be normally acknowledged by changing cmd_status to MFI_STAT_OK. In order to get acknowledgement of the IO is complete, the Thunderbolt command queue needs to be run through. I added a flag MFI_CMD_SCSI to indicate this command is being polled and to complete the Thunderbolt wrapper and indicate the result. This flag needs to be set in the JBOD case in case if that us using Thunderbolt card. When in the polling loop check for completed commands. - Remove mfi_tbolt_is_ldio and just do the check when needed. - Fix an issue when attaching of disk device happens when a device is already scheduled to be attached but hasn't attached. - add a tunable to allow raw disk attachment to CAM via: hw.mfi.allow_cam_disk_passthrough=1 - fixup aborting of commands (AEN and LD state change). Use a generic abort function and only wait the command being aborted not both. Thunderbolt cards don't seem to abort commands so the abort times out.

Fixes queuing issues where mfi_release_command blindly sets the cm_flags = 0 without first removing the command from the relavent queue. This was causing panics in the queue functions which check to ensure a command is not on another queue. Fixed some cases where the error from mfi_mapcmd was lost and where the command was never released / dequeued in error cases. Ensure that all failures to mfi_mapcmd are logged. Fixed possible null pointer exception in mfi_aen_setup if mfi_get_log_state failed. Fixed mfi_parse_entries & mfi_aen_setup not returning possible errors. Corrected MFI_DUMP_CMDS calls with invalid vars SC vs sc. Commands which have timed out now set cm_error to ETIMEDOUT and call mfi_complete which prevents them getting stuck in the busy queue forever. Fixed possible use of NULL pointer in mfi_tbolt_get_cmd. Changed output formats to be more easily recognisable when debugging. Optimised mfi_cmd_pool_tbolt cleanup. Made information about driver limiting commands always display as for modern cards this can be severe. Fixed mfi_tbolt_alloc_cmd out of memory case which previously didnt return an error. Added malloc checks for request_desc_pool including free when subsiquent errors are detected. Fixed overflow error in SIMD reply descriptor check. Fixed tbolt_cmd leak in mfi_build_and_issue_cmd if there's an error during IO build. Elimintated double checks on sc->mfi_aen_cm & sc->mfi_map_sync_cm in mfi_shutdown. Move local hdr calculation after error check in mfi_aen_complete. Fixed wakeup on NULL in mfi_aen_complete. Fixed mfi_aen_cm cleanup in mfi_process_fw_state_chg_isr not checking if it was NULL. Changed mfi_alloc_commands to error if bus_dmamap_create fails. Previously we would try to continue with the number of allocated commands but lots of places in the driver assume sc->mfi_max_fw_cmds is whats available so its unsafe to do this without lots of changes. Removed mfi_total_cmds as its no longer used due the above change. Corrected mfi_tbolt_alloc_cmd to return ENOMEM where appropriate. Fixed timeouts actually firing at double what they should. Setting hw.mfi.max_cmds=-1 now configures to use the controller max. A few style (9) fixes e.g. braced single line conditions and double blank lines Cleaned up queuing macros Removed invalid queuing tests for multiple queues Trap and deal with errors when doing sends in mfi_data_cb Refactored frame sending into one method with error checking of the return code so we can ensure commands aren't left on the queue after error. This ensures that mfi_mapcmd & mfi_data_cb leave the queue in a valid state. Refactored how commands are cleaned up, mfi_release_command now ensures that all queues and command state is maintained in a consistent state. Prevent NULL pointer use in mfi_tbolt_complete_cmd Fixed use of NULL sc->mfi_map_sync_cm in wakeup Added defines to help with output of mfi_cmd and header flags. Fixed mfi_tbolt_init_MFI_queue invalidating cm_index of the acquired mfi_cmd. Reset now reinitialises sync map as well as AEN. Fixed possible use of NULL pointer in mfi_build_and_issue_cmd Fixed mfi_tbolt_init_MFI_queue call to mfi_process_fw_state_chg_isr causing panic on failure. Ensure that tbolt cards always initialise next_host_reply_index and free_host_reply_index (based off mfi_max_fw_cmds) on both startup and reset as per the linux driver. Fixed mfi_tbolt_complete_cmd not acknowledging unknown commands so it didn't clear the controller. Prevent locks from being dropped and re-acquired in the following functions which was allowing multiple threads to enter critical methods such as mfi_tbolt_complete_cmd & mfi_process_fw_state_chg_isr:- * mfi_tbolt_init_MFI_queue * mfi_aen_complete / mfi_aen_register * mfi_tbolt_sync_map_info * mfi_get_log_state * mfi_parse_entries The locking for these functions was promoting to higher level methods. This also fixed MFI_LINUX_SET_AEN_2 which was already acquiring the lock, so would have paniced for recursive lock. This also required changing malloc of ld_sync in mfi_tbolt_sync_map_info to M_NOWAIT which can hence now fail but this was already expected as its return was being tested. Removed the assignment of cm_index in mfi_tbolt_init_MFI_queue which breaks the world if the cmd returned by mfi_dequeue_free isn't the first cmd. Fixed locking in mfi_data_cb, this is an async callback from bus_dmamap_load which could hence be called after the caller has dropped the lock. If we don't have the lock we aquire it and ensure we unlock before returning. Fixed locking mfi_comms_init when mfi_dequeue_free fails. Fixed mfi_build_and_issue_cmd not returning tbolt cmds aquired to the pool on error. Fixed mfi_abort not dropping the io lock when mfi_dequeue_free fails. Added hw.mfi.polled_cmd_timeout sysctl that enables tuning of polled timeouts. This shouldn't be reduced below 50 seconds as its used for firmware patching which can take quite some time. Added hw.mfi.fw_reset_test sysctl which is avaliable when compiled with MFI_DEBUG and allows the testing of controller reset that was provoking a large number of the issues encountered here.

If we don't have the lock we aquire it and ensure we unlock before returning. Fixed locking mfi_comms_init when mfi_dequeue_free fails. Fixed mfi_build_and_issue_cmd not returning tbolt cmds aquired to the pool on error. Fixed mfi_abort not dropping the io lock when mfi_dequeue_free fails. Added hw.mfi.polled_cmd_timeout sysctl that enables tuning of polled timeouts. This shouldn't be reduced below 50 seconds as its used for firmware patching which can take quite some time. Added hw.mfi.fw_reset_test sysctl which is avaliable when compiled with MFI_DEBUG and allows the testing of controller reset that was provoking a large number of the issues encountered here.

First cut at updating mfi(4) to support newer LSI MegaRAID SAS cards. Specifically, add support for "Drake Skinny" and "ThunderBolt" LSI cards. Initial code was supplied by LSI under BSD license. Several improvements were done by myself. Such things like making it work in a static kernel, be able to boot of the RAID, performance improvements. I removed some fairly complicated code that seemed to directly access the disks under the firmware. It doesn't seem to be needed and significantly slowed down the performance of the driver and caused tons of sense errors to be reported. This code is being checked in this area so others can help me get it into shape to commit into the FreeBSD tree. Assistance has been volunteered by iXsystems. We might want to re-work the JBOD attachment that creates /dev/mfisyspd? node for each disk. Performance is faster then prior cards. It works okay with WITNESS and INVARIANTS on amd64 and i386. I recall seeing a use after free time bug with FreeBSD 8 and a Drake Skinny card with WITNESS and INVARIANTS on. First task is get all of the new structures to be named in FreeBSD style format. Next is probably to deal with the 64bit addressing changes that are mostly around the #ifdef __amd64__ checks. Thanks to LSI for providing the initial code. Obtained from: LSI

Separate the parallel scsi knowledge out of the core of the XPT, and modularize it so that new transports can be created. Add a transport for SATA Add a periph+protocol layer for ATA Add a driver for AHCI-compliant hardware. Add a maxio field to CAM so that drivers can advertise their max I/O capability. Modify various drivers so that they are insulated from the value of MAXPHYS. The new ATA/SATA code supports AHCI-compliant hardware, and will override the classic ATA driver if it is loaded as a module at boot time or compiled into the kernel. The stack now support NCQ (tagged queueing) for increased performance on modern SATA drives. It also supports port multipliers. ATA drives are accessed via 'ada' device nodes. ATAPI drives are accessed via 'cd' device nodes. They can all be enumerated and manipulated via camcontrol, just like SCSI drives. SCSI commands are not translated to their ATA equivalents; ATA native commands are used throughout the entire stack, including camcontrol. See the camcontrol manpage for further details. Testing this code may require that you update your fstab, and possibly modify your BIOS to enable AHCI functionality, if available. This code is very experimental at the moment. The userland ABI/API has changed, so applications will need to be recompiled. It may change further in the near future. The 'ada' device name may also change as more infrastructure is completed in this project. The goal is to eventually put all CAM busses and devices until newbus, allowing for interesting topology and management options. Few functional changes will be seen with existing SCSI/SAS/FC drivers, though the userland ABI has still changed. In the future, transports specific modules for SAS and FC may appear in order to better support the topologies and capabilities of these technologies. The modularization of CAM and the addition of the ATA/SATA modules is meant to break CAM out of the mold of being specific to SCSI, letting it grow to be a framework for arbitrary transports and protocols. It also allows drivers to be written to support discrete hardware without jeopardizing the stability of non-related hardware. While only an AHCI driver is provided now, a Silicon Image driver is also in the works. Drivers for ICH1-4, ICH5-6, PIIX, classic IDE, and any other hardware is possible and encouraged. Help with new transports is also encouraged. Submitted by: scottl, mav Approved by: re

Fixes queuing issues where mfi_release_command blindly sets the cm_flags = 0 without first removing the command from the relavent queue. This was causing panics in the queue functions which check to ensure a command is not on another queue. Fixed some cases where the error from mfi_mapcmd was lost and where the command was never released / dequeued in error cases. Ensure that all failures to mfi_mapcmd are logged. Fixed possible null pointer exception in mfi_aen_setup if mfi_get_log_state failed. Fixed mfi_parse_entries & mfi_aen_setup not returning possible errors. Corrected MFI_DUMP_CMDS calls with invalid vars SC vs sc. Commands which have timed out now set cm_error to ETIMEDOUT and call mfi_complete which prevents them getting stuck in the busy queue forever. Fixed possible use of NULL pointer in mfi_tbolt_get_cmd. Changed output formats to be more easily recognisable when debugging. Optimised mfi_cmd_pool_tbolt cleanup. Made information about driver limiting commands always display as for modern cards this can be severe. Fixed mfi_tbolt_alloc_cmd out of memory case which previously didnt return an error. Added malloc checks for request_desc_pool including free when subsiquent errors are detected. Fixed overflow error in SIMD reply descriptor check. Fixed tbolt_cmd leak in mfi_build_and_issue_cmd if there's an error during IO build. Elimintated double checks on sc->mfi_aen_cm & sc->mfi_map_sync_cm in mfi_shutdown. Move local hdr calculation after error check in mfi_aen_complete. Fixed wakeup on NULL in mfi_aen_complete. Fixed mfi_aen_cm cleanup in mfi_process_fw_state_chg_isr not checking if it was NULL. Changed mfi_alloc_commands to error if bus_dmamap_create fails. Previously we would try to continue with the number of allocated commands but lots of places in the driver assume sc->mfi_max_fw_cmds is whats available so its unsafe to do this without lots of changes. Removed mfi_total_cmds as its no longer used due the above change. Corrected mfi_tbolt_alloc_cmd to return ENOMEM where appropriate. Fixed timeouts actually firing at double what they should. Setting hw.mfi.max_cmds=-1 now configures to use the controller max. A few style (9) fixes e.g. braced single line conditions and double blank lines Cleaned up queuing macros Removed invalid queuing tests for multiple queues Trap and deal with errors when doing sends in mfi_data_cb Refactored frame sending into one method with error checking of the return code so we can ensure commands aren't left on the queue after error. This ensures that mfi_mapcmd & mfi_data_cb leave the queue in a valid state. Refactored how commands are cleaned up, mfi_release_command now ensures that all queues and command state is maintained in a consistent state. Prevent NULL pointer use in mfi_tbolt_complete_cmd Fixed use of NULL sc->mfi_map_sync_cm in wakeup Added defines to help with output of mfi_cmd and header flags. Fixed mfi_tbolt_init_MFI_queue invalidating cm_index of the acquired mfi_cmd. Reset now reinitialises sync map as well as AEN. Fixed possible use of NULL pointer in mfi_build_and_issue_cmd Fixed mfi_tbolt_init_MFI_queue call to mfi_process_fw_state_chg_isr causing panic on failure. Ensure that tbolt cards always initialise next_host_reply_index and free_host_reply_index (based off mfi_max_fw_cmds) on both startup and reset as per the linux driver. Fixed mfi_tbolt_complete_cmd not acknowledging unknown commands so it didn't clear the controller. Prevent locks from being dropped and re-acquired in the following functions which was allowing multiple threads to enter critical methods such as mfi_tbolt_complete_cmd & mfi_process_fw_state_chg_isr:- * mfi_tbolt_init_MFI_queue * mfi_aen_complete / mfi_aen_register * mfi_tbolt_sync_map_info * mfi_get_log_state * mfi_parse_entries The locking for these functions was promoting to higher level methods. This also fixed MFI_LINUX_SET_AEN_2 which was already acquiring the lock, so would have paniced for recursive lock. This also required changing malloc of ld_sync in mfi_tbolt_sync_map_info to M_NOWAIT which can hence now fail but this was already expected as its return was being tested. Removed the assignment of cm_index in mfi_tbolt_init_MFI_queue which breaks the world if the cmd returned by mfi_dequeue_free isn't the first cmd.
