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

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.

Change the event log dump on initial boot to use get_event versus AEN. This makes the boot messages cleaner. I now know how this structure works so I can implement it versus guessing. Remove the not ready type code since it is ready now. I added the time stamp/locale/class so people can parse messages better. Create a sysctl so that we can set the locale/class level.

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.

Fix panics triggered by older mfiutil binaries run on the new mfi(4) driver. The new driver changed the size of the mfi_dcmd_frame structure in such a way that a MFI_IOC_PASSTHRU ioctl from an old amd64 binary is treated as an MFI_IOC_PASSTHRU32 ioctl in the new driver. As a result, the user pointer is treated as the buffer length. mfi_user_command() doesn't have a bounds check on the buffer length, so it passes a really big value to malloc() which panics when it tries to exhaust the kmem_map. Fix this two ways: - Only honor MFI_IOC_PASSTHRU32 if the binary has the SV_ILP32 flag set, otherwise treat it as an unknown ioctl. - Add a bounds check on the buffer length passed by the user. For now it fails any user attempts to use a buffer larger than 1MB. While here, fix a few other nits: - Remove an unnecessary check for a NULL return from malloc(M_WAITOK). - Use the ENOTTY errno for invalid ioctl commands instead of ENOENT. 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

Adjust the handling of pending log events during boot: - Fetch events from the controller in batches of 15 rather than a single event at a time. - When fetching events from the controller, honor the event class and locale settings (via hw.mfi tunables). This also allows the firmware to skip over unwanted log entries resulting in fewer requests to the controller if there many unwanted log entries since the last clean shutdown. - Don't drop the driver mutex while decoding an event. - If we get an error other than MFI_STAT_NOT_FOUND (basically EOF for hitting the end of the event log) then emit a warning and bail on processing further log entries.

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.

- 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. 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

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.

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.

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

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.

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.

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.

MFhead_mfi r227905 Improved timeout support from Scott. MFhead_mfi r228108 Make file. MFhead_mfi r228208 Fixed botched merge of Skinny support and enhanced handling in call back routine. MFhead_mfi r228279 Remove superfluous !TAILQ_EMPTY() checks before TAILQ_FOREACH(). MFhead_mfi r228310 Move mfi_decode_evt() to taskqueue. MFhead_mfi r228320 Implement MFI_DEBUG for 64bit S/G lists. MFhead_mfi r231988 Restore structure layout by reverting the array header to use [0] instead of [1]. MFhead_mfi r232412 Put wildcard pattern later in the match table. MFhead_mfi r232413 Use lower case for hexadecimal numbers to match surrounding style. MFhead_mfi r232414 Add more Thunderbolt variants. MFhead_mfi r232888 Don't act on events prior to boot or when shutting down. Add hw.mfi.detect_jbod_change to enable or disable acting on JBOD type of disks being added on insert and removed on removing. Switch hw.mfi.msi to 1 by default since it works better on newer cards. MFhead_mfi r233016 Release driver lock before taking Giant when deleting children. Use TAILQ_FOREACH_SAFE when items can be deleted. Make code a little simplier to follow. Fix a couple more style issues. MFhead_mfi r233620 Update mfi_spare/mfi_array with the actual number of elements for array_ref and pd. Change these max. #define names to avoid name space collisions. This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive.

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.

Switch from make_dev_alias to make_dev_alias_p since make_dev_alias_p can gracefully fail if the /dev/megaraid_sas_ioctl_node symlink already exists. This can happen if mfi(4) and mrsas(4) are both attached to cards and providing Linux emulation support. Let the first one win. An equivalent change needs to be done to mrsas(4). Extra credit would be to pass the Linux emulation call to the other driver when appropriate. This will probably be a rare case and the user can manually change where the symlink points to.

TAILQ_INIT(&sc->mfi_ld_tqh);
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 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.

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

Make MAXPHYS tunable. Bump MAXPHYS to 1M. Replace MAXPHYS by runtime variable maxphys. It is initialized from MAXPHYS by default, but can be also adjusted with the tunable kern.maxphys. Make b_pages[] array in struct buf flexible. Size b_pages[] for buffer cache buffers exactly to atop(maxbcachebuf) (currently it is sized to atop(MAXPHYS)), and b_pages[] for pbufs is sized to atop(maxphys) + 1. The +1 for pbufs allow several pbuf consumers, among them vmapbuf(), to use unaligned buffers still sized to maxphys, esp. when such buffers come from userspace (*). Overall, we save significant amount of otherwise wasted memory in b_pages[] for buffer cache buffers, while bumping MAXPHYS to desired high value. Eliminate all direct uses of the MAXPHYS constant in kernel and driver sources, except a place which initialize maxphys. Some random (and arguably weird) uses of MAXPHYS, e.g. in linuxolator, are converted straight. Some drivers, which use MAXPHYS to size embeded structures, get private MAXPHYS-like constant; their convertion is out of scope for this work. Changes to cam/, dev/ahci, dev/ata, dev/mpr, dev/mpt, dev/mvs, dev/siis, where either submitted by, or based on changes by mav.

status = sc->mfi_read_fw_status(sc);
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.

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

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

&sc->mfi_tb_init_dmat)) {
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.

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

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

sc->mfi_disable_intr(sc);
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.

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.

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.

This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive. Thanks to the many that helped, LSI for the initial code drop, mav, delphij, jhb, sbruno that all helped with code and testing.

- 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 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.

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.

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.

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.

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.

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

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.

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

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.

mtx_lock(&sc->mfi_io_lock);
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.

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.

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

MFhead_mfi r227574 Style MFhead_mfi r227579 Use bus_addr_t instead of uintXX_t. MFhead_mfi r227580 MSI support MFhead_mfi r227612 More bus_addr_t and remove "#ifdef __amd64__". MFhead_mfi r227905 Improved timeout support from Scott. MFhead_mfi r228108 Make file. MFhead_mfi r228208 Fixed botched merge of Skinny support and enhanced handling in call back routine. MFhead_mfi r228279 Remove superfluous !TAILQ_EMPTY() checks before TAILQ_FOREACH(). MFhead_mfi r228310 Move mfi_decode_evt() to taskqueue. MFhead_mfi r228320 Implement MFI_DEBUG for 64bit S/G lists. MFhead_mfi r231988 Restore structure layout by reverting the array header to use [0] instead of [1]. MFhead_mfi r232412 Put wildcard pattern later in the match table. MFhead_mfi r232413 Use lower case for hexadecimal numbers to match surrounding style. MFhead_mfi r232414 Add more Thunderbolt variants. MFhead_mfi r232888 Don't act on events prior to boot or when shutting down. Add hw.mfi.detect_jbod_change to enable or disable acting on JBOD type of disks being added on insert and removed on removing. Switch hw.mfi.msi to 1 by default since it works better on newer cards. MFhead_mfi r233016 Release driver lock before taking Giant when deleting children. Use TAILQ_FOREACH_SAFE when items can be deleted. Make code a little simplier to follow. Fix a couple more style issues. MFhead_mfi r233620 Update mfi_spare/mfi_array with the actual number of elements for array_ref and pd. Change these max. #define names to avoid name space collisions. This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive. Thanks to the many that helped, LSI for the initial code drop, mav, delphij, jhb, sbruno that all helped with code and testing.

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

MFhead_mfi r227068 First cut of new HW support from LSI and merge into FreeBSD. Supports Drake Skinny and ThunderBolt cards. MFhead_mfi r227574 Style MFhead_mfi r227579 Use bus_addr_t instead of uintXX_t. MFhead_mfi r227580 MSI support MFhead_mfi r227612 More bus_addr_t and remove "#ifdef __amd64__". MFhead_mfi r227905 Improved timeout support from Scott. MFhead_mfi r228108 Make file. MFhead_mfi r228208 Fixed botched merge of Skinny support and enhanced handling in call back routine. MFhead_mfi r228279 Remove superfluous !TAILQ_EMPTY() checks before TAILQ_FOREACH(). MFhead_mfi r228310 Move mfi_decode_evt() to taskqueue. MFhead_mfi r228320 Implement MFI_DEBUG for 64bit S/G lists. MFhead_mfi r231988 Restore structure layout by reverting the array header to use [0] instead of [1]. MFhead_mfi r232412 Put wildcard pattern later in the match table. MFhead_mfi r232413 Use lower case for hexadecimal numbers to match surrounding style. MFhead_mfi r232414 Add more Thunderbolt variants. MFhead_mfi r232888 Don't act on events prior to boot or when shutting down. Add hw.mfi.detect_jbod_change to enable or disable acting on JBOD type of disks being added on insert and removed on removing. Switch hw.mfi.msi to 1 by default since it works better on newer cards. MFhead_mfi r233016 Release driver lock before taking Giant when deleting children. Use TAILQ_FOREACH_SAFE when items can be deleted. Make code a little simplier to follow. Fix a couple more style issues. MFhead_mfi r233620 Update mfi_spare/mfi_array with the actual number of elements for array_ref and pd. Change these max. #define names to avoid name space collisions. This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive. Thanks to the many that helped, LSI for the initial code drop, mav, delphij, jhb, sbruno that all helped with code and testing.

int error;
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.

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.

Change the event log dump on initial boot to use get_event versus AEN. This makes the boot messages cleaner. I now know how this structure works so I can implement it versus guessing. Remove the not ready type code since it is ready now. I added the time stamp/locale/class so people can parse messages better. Create a sysctl so that we can set the locale/class level.

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 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.

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.

This also allows the firmware to skip over unwanted log entries resulting in fewer requests to the controller if there many unwanted log entries since the last clean shutdown. - Don't drop the driver mutex while decoding an event. - If we get an error other than MFI_STAT_NOT_FOUND (basically EOF for hitting the end of the event log) then emit a warning and bail on processing further log entries.

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.

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 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

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.

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.

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

if (sc->mfi_tb_init_busaddr != 0)
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.

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

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.

/* Give defered I/O a chance to run */
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.

MFhead_mfi r227068 First cut of new HW support from LSI and merge into FreeBSD. Supports Drake Skinny and ThunderBolt cards. MFhead_mfi r227574 Style MFhead_mfi r227579 Use bus_addr_t instead of uintXX_t. MFhead_mfi r227580 MSI support MFhead_mfi r227612 More bus_addr_t and remove "#ifdef __amd64__". MFhead_mfi r227905 Improved timeout support from Scott. MFhead_mfi r228108 Make file. MFhead_mfi r228208 Fixed botched merge of Skinny support and enhanced handling in call back routine. MFhead_mfi r228279 Remove superfluous !TAILQ_EMPTY() checks before TAILQ_FOREACH(). MFhead_mfi r228310 Move mfi_decode_evt() to taskqueue. MFhead_mfi r228320 Implement MFI_DEBUG for 64bit S/G lists. MFhead_mfi r231988 Restore structure layout by reverting the array header to use [0] instead of [1]. MFhead_mfi r232412 Put wildcard pattern later in the match table. MFhead_mfi r232413 Use lower case for hexadecimal numbers to match surrounding style. MFhead_mfi r232414 Add more Thunderbolt variants. MFhead_mfi r232888 Don't act on events prior to boot or when shutting down. Add hw.mfi.detect_jbod_change to enable or disable acting on JBOD type of disks being added on insert and removed on removing. Switch hw.mfi.msi to 1 by default since it works better on newer cards. MFhead_mfi r233016 Release driver lock before taking Giant when deleting children. Use TAILQ_FOREACH_SAFE when items can be deleted. Make code a little simplier to follow. Fix a couple more style issues. MFhead_mfi r233620 Update mfi_spare/mfi_array with the actual number of elements for array_ref and pd. Change these max. #define names to avoid name space collisions. This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive. Thanks to the many that helped, LSI for the initial code drop, mav, delphij, jhb, sbruno that all helped with code and testing.

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.

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.

- 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.

Change the internal API for polled commands. Calling mfi_polled_command after calling mfi_mapcmd is no longer needed, so long as the MFI_CMD_POLLED flag is set.

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.

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.

found = 0;
for (i = 0; i < pdlist->count; i++) {
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.

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.

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.

Instead of using scsi probes to do device discovery, use the firmware commands to grab the device listing. This resolves issues using multiple volumes, where each volume was actually internally pointing to target 0.

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

Tweak the output of event log messages from the controller: - Each log entry contains a text description in the "description" field of the entry. The existing decode logic always ended up duplicating information that was already in the description string. This made the logs overly verbose. Now we just print out the description string. - Add some simple parsing of the timestamp and event classes. Reviewed by: ambrisko, scottl MFC after: 2 weeks

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

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.

- 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.

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

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.

In order to maximize the re-usability of kernel code in user space this patch modifies makesyscalls.sh to prefix all of the non-compatibility calls (e.g. not linux_, freebsd32_) with sys_ and updates the kernel entry points and all places in the code that use them. It also fixes an additional name space collision between the kernel function psignal and the libc function of the same name by renaming the kernel psignal kern_psignal(). By introducing this change now we will ease future MFCs that change syscalls. Reviewed by: rwatson Approved by: re (bz)

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.

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.

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.

Adjust the handling of pending log events during boot: - Fetch events from the controller in batches of 15 rather than a single event at a time. - When fetching events from the controller, honor the event class and locale settings (via hw.mfi tunables). This also allows the firmware to skip over unwanted log entries resulting in fewer requests to the controller if there many unwanted log entries since the last clean shutdown. - Don't drop the driver mutex while decoding an event. - If we get an error other than MFI_STAT_NOT_FOUND (basically EOF for hitting the end of the event log) then emit a warning and bail on processing further log entries.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

mfi_build_ldio(struct mfi_softc *sc, struct bio *bio)
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

Without this change, mfi(4) always sends 10 byte READ and WRITE commands, which will cause data corruption when device is larger than 2^32 sectors.

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.

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.

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

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.

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

Reform the busdma API so that new types may be added without modifying every architecture's busdma_machdep.c. It is done by unifying the bus_dmamap_load_buffer() routines so that they may be called from MI code. The MD busdma is then given a chance to do any final processing in the complete() callback. The cam changes unify the bus_dmamap_load* handling in cam drivers. The arm and mips implementations are updated to track virtual addresses for sync(). Previously this was done in a type specific way. Now it is done in a generic way by recording the list of virtuals in the map.

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.

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.

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.

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.

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.

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.

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.

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.

Change the internal API for polled commands. Calling mfi_polled_command after calling mfi_mapcmd is no longer needed, so long as the MFI_CMD_POLLED flag is set. This change eliminates the possibility of a polled command getting posted twice to the driver. This is turn fixes panics on shutdown when INVARIANTS is set. Sponsored by: Ironport

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.

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

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.

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).

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.

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.

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.

Some relatively minor changes and bug fixes: 1) s/mi/mfi/ in FreeBSD ioctl path 2) add in "\n" on various failure messages 3) cap the length of time to abort an AEN command 4) fix passing sense data back to user to make Dell's Linux firmware upgrade tool happy. 5) bump the MFI_POLL_TIMEOUT_SECS from 10s to 50s since the firmware flash command can take ~40s to return. This is some clean-up and enables RAID firmware to updated via Dell's tool. Note Dell's tool requires the updates to the Linux emulator that has been done in -current with TLS etc. I need to discuss with scottl how to better submit mfi commands to the firmware via the ioctl path so we don't do it in polled mode.

- 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 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.

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.

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.

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.

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.

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.

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.

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.

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.

Fix a couple more style issues. MFhead_mfi r233620 Update mfi_spare/mfi_array with the actual number of elements for array_ref and pd. Change these max. #define names to avoid name space collisions. This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive.

if (syspd)
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

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

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.

Fix panics triggered by older mfiutil binaries run on the new mfi(4) driver. The new driver changed the size of the mfi_dcmd_frame structure in such a way that a MFI_IOC_PASSTHRU ioctl from an old amd64 binary is treated as an MFI_IOC_PASSTHRU32 ioctl in the new driver. As a result, the user pointer is treated as the buffer length. mfi_user_command() doesn't have a bounds check on the buffer length, so it passes a really big value to malloc() which panics when it tries to exhaust the kmem_map. Fix this two ways: - Only honor MFI_IOC_PASSTHRU32 if the binary has the SV_ILP32 flag set, otherwise treat it as an unknown ioctl. - Add a bounds check on the buffer length passed by the user. For now it fails any user attempts to use a buffer larger than 1MB.

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.

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.

- Add in FreeBSD native ioctl that models the Linux version. - Add a translation so the Linux ioctl's don't conflict with the FreeBSD definition. - Assume Linux 32bit emulation on amd64. This was tested on i386 and amd64 with the 32bit Linux MegaCli. Eventually we should do a 32bit native FreeBSD translation app.

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 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

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.

case MFIIO_PASSTHRU32:
Fix panics triggered by older mfiutil binaries run on the new mfi(4) driver. The new driver changed the size of the mfi_dcmd_frame structure in such a way that a MFI_IOC_PASSTHRU ioctl from an old amd64 binary is treated as an MFI_IOC_PASSTHRU32 ioctl in the new driver. As a result, the user pointer is treated as the buffer length. mfi_user_command() doesn't have a bounds check on the buffer length, so it passes a really big value to malloc() which panics when it tries to exhaust the kmem_map. Fix this two ways: - Only honor MFI_IOC_PASSTHRU32 if the binary has the SV_ILP32 flag set, otherwise treat it as an unknown ioctl. - Add a bounds check on the buffer length passed by the user. For now it fails any user attempts to use a buffer larger than 1MB. While here, fix a few other nits: - Remove an unnecessary check for a NULL return from malloc(M_WAITOK). - Use the ENOTTY errno for invalid ioctl commands instead of ENOENT. 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

MFhead_mfi r231988 Restore structure layout by reverting the array header to use [0] instead of [1]. MFhead_mfi r232412 Put wildcard pattern later in the match table. MFhead_mfi r232413 Use lower case for hexadecimal numbers to match surrounding style. MFhead_mfi r232414 Add more Thunderbolt variants. MFhead_mfi r232888 Don't act on events prior to boot or when shutting down. Add hw.mfi.detect_jbod_change to enable or disable acting on JBOD type of disks being added on insert and removed on removing. Switch hw.mfi.msi to 1 by default since it works better on newer cards. MFhead_mfi r233016 Release driver lock before taking Giant when deleting children. Use TAILQ_FOREACH_SAFE when items can be deleted. Make code a little simplier to follow. Fix a couple more style issues. MFhead_mfi r233620 Update mfi_spare/mfi_array with the actual number of elements for array_ref and pd. Change these max. #define names to avoid name space collisions. This will require an update to mfiutil It avoids mfiutil having to do a magic calculation. Add a note and #define to state that a "SYSTEM" disk is really what the firmware calls a "JBOD" drive. Thanks to the many that helped, LSI for the initial code drop, mav, delphij, jhb, sbruno that all helped with code and testing.

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

Some relatively minor changes and bug fixes: 1) s/mi/mfi/ in FreeBSD ioctl path 2) add in "\n" on various failure messages 3) cap the length of time to abort an AEN command 4) fix passing sense data back to user to make Dell's Linux firmware upgrade tool happy. 5) bump the MFI_POLL_TIMEOUT_SECS from 10s to 50s since the firmware flash command can take ~40s to return. This is some clean-up and enables RAID firmware to updated via Dell's tool. Note Dell's tool requires the updates to the Linux emulator that has been done in -current with TLS etc. I need to discuss with scottl how to better submit mfi commands to the firmware via the ioctl path so we don't do it in polled mode.

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.

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

This also fixed MFI_LINUX_SET_AEN_2 which was already acquiring the lock, so would have paniced for recursive lock.

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.

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.

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.

Remove forced timeout of in-flight commands from mfi_timeout. While this prevents commands getting stuck forever there is no way to guarantee that data from the command hasn't been committed to the device. In addition older mfi firmware has a bug that would cause the controller to frequently stall IO for over our timeout value, which when combined with a forced timeout often resulted in panics in UFS; which would otherwise be avoided when the command eventually completed if left alone. For reference this timeout issue is resolved in Dell FW package 21.2.1-0000. Fixed FW package version for none Dell controller will likely vary. MFC after: 2 days

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.

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.
