- Updated all files with 2015 Avago copyright, and updated LSI's copyright dates. - Changed all of the PCI device strings from LSI to Avago Technologies (LSI). - Added a sysctl variable to control how StartStopUnit behavior works. User can select to spin down disks based on if disk is SSD or HDD. - Inquiry data is required to tell if a disk will support SSU at shutdown or not. Due to the addition of mpssas_async, which gets Advanced Info but not Inquiry data, the setting of supports_SSU was moved to the mpssas_scsiio_complete function, which snoops for any Inquiry commands. And, since disks are shutdown as a target and not a LUN, this process was simplified by basing it on targets and not LUNs. - Added a sysctl variable that sets the amount of time to retry after sending a failed SATA ID command. This helps with some bad disks and large disks that require a lot of time to spin up. Part of this change was to add a callout to handle timeouts with the SATA ID command. The callout function is called mpssas_ata_id_timeout(). (Fixes PR 191348) - Changed the way resets work by allowing I/O to continue to devices that are not currently under a reset condition. This uses devq's instead of simq's and makes use of the MPSSAS_TARGET_INRESET flag. This change also adds a function called mpssas_prepare_tm(). - Some changes were made to reduce code duplication when getting a SAS address for a SATA disk. - Fixed some formatting and whitespace. - Bump version of mps driver to 20.00.00.00-fbsd PR: 191348 Reviewed by: ken, scottl Approved by: ken, scottl MFC after: 2 weeks

Bring in a number of mps(4) driver fixes from LSI: 1. Fixed timeout specification for the msleep in mps_wait_command(). Added 30 second timeout for mps_wait_command() calls in mps_user.c. 2. Make sure we call mps_detach_user() from the kldunload path. 3. Raid Hotplug behavior change. The driver now removes a volume when it goes to a failed state, so we also need to add volume back to the OS when it goes to opitimal/degraded/online from failed/missing. Handle raid volume add and remove from the IR_Volume event. 4. Added some more debugging information. 5. Replace xpt_async(AC_LOST_DEVICE, path, NULL) with mpssas_rescan_target(). This is to work around a panic in CAM that shows up when adding a drive with a rescan and removing another device from the driver thread with an AC_LOST_DEVICE async notification. This problem was encountered in testing with the LSI sas2ircu utility, which was used to create a RAID volume from physical disks. The driver has to create the RAID volume target and remove the physical disk targets, and triggered a panic in the process. The CAM issue needs to be fully diagnosed and fixed, but this works around the issue for now. 6. Fix some memory initialization issues in mps_free_command(). 7. Resolve the "devq freeze forever" issue. This was caused by the internal read capacity command issued in the non-head version of the driver. When the command completed with an error, the driver wasn't unfreezing thd device queue. The version in head uses the CAM infrastructure for getting the read capacity information, and therefore doesn't have the same issue. 8. Bump the version to 13.00.00.00-fbsd.

Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10. Check the actual status of Message unit reset (mps_message_unit_reset).Previously FreeBSD Driver just writes MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack (it just wait for 50 millisecond). So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS. FreeBSD does bus rescan as older Parallel scsi style. So Driver needs to handle which Drive is visible to OS. That is a reason we have to clear off targ information for PDs.

case MPI2_EVENT_SAS_TOPO_RC_TARG_NOT_RESPONDING:
Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10. Check the actual status of Message unit reset (mps_message_unit_reset).Previously FreeBSD Driver just writes MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack (it just wait for 50 millisecond). So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS. FreeBSD does bus rescan as older Parallel scsi style. So Driver needs to handle which Drive is visible to OS. That is a reason we have to clear off targ information for PDs. Again, above logic was implemented long time ago. Similar concept we have for non-wd also. For that, LSI have introduced different logic to hide PDs. Eventually, because of above gap, when Phy goes offline, we observe below failure. That is what Driver is not doing complete removal of device with FW.

Bring in a number of mps(4) driver fixes from LSI: 1. Fixed timeout specification for the msleep in mps_wait_command(). Added 30 second timeout for mps_wait_command() calls in mps_user.c. 2. Make sure we call mps_detach_user() from the kldunload path. 3. Raid Hotplug behavior change. The driver now removes a volume when it goes to a failed state, so we also need to add volume back to the OS when it goes to opitimal/degraded/online from failed/missing. Handle raid volume add and remove from the IR_Volume event. 4. Added some more debugging information. 5. Replace xpt_async(AC_LOST_DEVICE, path, NULL) with mpssas_rescan_target(). This is to work around a panic in CAM that shows up when adding a drive with a rescan and removing another device from the driver thread with an AC_LOST_DEVICE async notification. This problem was encountered in testing with the LSI sas2ircu utility, which was used to create a RAID volume from physical disks. The driver has to create the RAID volume target and remove the physical disk targets, and triggered a panic in the process. The CAM issue needs to be fully diagnosed and fixed, but this works around the issue for now. 6. Fix some memory initialization issues in mps_free_command(). 7. Resolve the "devq freeze forever" issue. This was caused by the internal read capacity command issued in the non-head version of the driver. When the command completed with an error, the driver wasn't unfreezing thd device queue. The version in head uses the CAM infrastructure for getting the read capacity information, and therefore doesn't have the same issue. 8. Bump the version to 13.00.00.00-fbsd.

Bring in a number of mps(4) driver fixes from LSI: 1. Fixed timeout specification for the msleep in mps_wait_command(). Added 30 second timeout for mps_wait_command() calls in mps_user.c. 2. Make sure we call mps_detach_user() from the kldunload path. 3. Raid Hotplug behavior change. The driver now removes a volume when it goes to a failed state, so we also need to add volume back to the OS when it goes to opitimal/degraded/online from failed/missing. Handle raid volume add and remove from the IR_Volume event. 4. Added some more debugging information. 5. Replace xpt_async(AC_LOST_DEVICE, path, NULL) with mpssas_rescan_target(). This is to work around a panic in CAM that shows up when adding a drive with a rescan and removing another device from the driver thread with an AC_LOST_DEVICE async notification. This problem was encountered in testing with the LSI sas2ircu utility, which was used to create a RAID volume from physical disks. The driver has to create the RAID volume target and remove the physical disk targets, and triggered a panic in the process. The CAM issue needs to be fully diagnosed and fixed, but this works around the issue for now. 6. Fix some memory initialization issues in mps_free_command(). 7. Resolve the "devq freeze forever" issue. This was caused by the internal read capacity command issued in the non-head version of the driver. When the command completed with an error, the driver wasn't unfreezing thd device queue. The version in head uses the CAM infrastructure for getting the read capacity information, and therefore doesn't have the same issue. 8. Bump the version to 13.00.00.00-fbsd. (this is very close to LSI's internal stable driver 13.00.00.00) Submitted by: Kashyap Desai <Kashyap.Desai@lsi.com> MFC after: 3 days

Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10. Check the actual status of Message unit reset (mps_message_unit_reset).Previously FreeBSD Driver just writes MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack (it just wait for 50 millisecond). So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS. FreeBSD does bus rescan as older Parallel scsi style. So Driver needs to handle which Drive is visible to OS. That is a reason we have to clear off targ information for PDs. Again, above logic was implemented long time ago. Similar concept we have for non-wd also. For that, LSI have introduced different logic to hide PDs. Eventually, because of above gap, when Phy goes offline, we observe below failure. That is what Driver is not doing complete removal of device with FW.

Bring in a number of mps(4) driver fixes from LSI: 1. Fixed timeout specification for the msleep in mps_wait_command(). Added 30 second timeout for mps_wait_command() calls in mps_user.c. 2. Make sure we call mps_detach_user() from the kldunload path. 3. Raid Hotplug behavior change. The driver now removes a volume when it goes to a failed state, so we also need to add volume back to the OS when it goes to opitimal/degraded/online from failed/missing. Handle raid volume add and remove from the IR_Volume event. 4. Added some more debugging information. 5. Replace xpt_async(AC_LOST_DEVICE, path, NULL) with mpssas_rescan_target(). This is to work around a panic in CAM that shows up when adding a drive with a rescan and removing another device from the driver thread with an AC_LOST_DEVICE async notification.

Resolve the "devq freeze forever" issue. This was caused by the internal read capacity command issued in the non-head version of the driver. When the command completed with an error, the driver wasn't unfreezing thd device queue.

Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10. Check the actual status of Message unit reset (mps_message_unit_reset).Previously FreeBSD Driver just writes MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack (it just wait for 50 millisecond). So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS.

So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS. FreeBSD does bus rescan as older Parallel scsi style. So Driver needs to handle which Drive is visible to OS. That is a reason we have to clear off targ information for PDs. Again, above logic was implemented long time ago. Similar concept we have for non-wd also. For that, LSI have introduced different logic to hide PDs. Eventually, because of above gap, when Phy goes offline, we observe below failure. That is what Driver is not doing complete removal of device with FW.

Returning "CAM_SEL_TIMEOUT" instead of "CAM_TID_INVALID" error code on request to the Target IDs that have no devices conected at that moment. As if "CAM_TID_INVALID" error code is returned to the CAM Layaer then it results in a huge chain of errors in verbose kernel messages on boot and every hot-plug event.

Bring in a number of mps(4) driver fixes from LSI: 1. Fixed timeout specification for the msleep in mps_wait_command(). Added 30 second timeout for mps_wait_command() calls in mps_user.c. 2. Make sure we call mps_detach_user() from the kldunload path. 3. Raid Hotplug behavior change. The driver now removes a volume when it goes to a failed state, so we also need to add volume back to the OS when it goes to opitimal/degraded/online from failed/missing. Handle raid volume add and remove from the IR_Volume event. 4. Added some more debugging information. 5. Replace xpt_async(AC_LOST_DEVICE, path, NULL) with mpssas_rescan_target(). This is to work around a panic in CAM that shows up when adding a drive with a rescan and removing another device from the driver thread with an AC_LOST_DEVICE async notification. This problem was encountered in testing with the LSI sas2ircu utility, which was used to create a RAID volume from physical disks. The driver has to create the RAID volume target and remove the physical disk targets, and triggered a panic in the process. The CAM issue needs to be fully diagnosed and fixed, but this works around the issue for now. 6. Fix some memory initialization issues in mps_free_command(). 7. Resolve the "devq freeze forever" issue. This was caused by the internal read capacity command issued in the non-head version of the driver. When the command completed with an error, the driver wasn't unfreezing thd device queue. The version in head uses the CAM infrastructure for getting the read capacity information, and therefore doesn't have the same issue. 8. Bump the version to 13.00.00.00-fbsd. (this is very close to LSI's internal stable driver 13.00.00.00) Submitted by: Kashyap Desai <Kashyap.Desai@lsi.com> MFC after: 3 days

Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10.

Eventually, because of above gap, when Phy goes offline, we observe below failure. That is what Driver is not doing complete removal of device with FW.

Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10. Check the actual status of Message unit reset (mps_message_unit_reset).Previously FreeBSD Driver just writes MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack (it just wait for 50 millisecond). So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS.

CAM and mps(4) driver scanning changes. Add a PIM_NOSCAN flag to the CAM path inquiry CCB. This tells CAM not to perform a rescan on a bus when it is registered.

Changes to make mps(4) and mpr(4) handle reinit with reallocation. When the mps(4) and mpr(4) drivers need to reinitialize the firmware, they sometimes need to reallocate all of the memory allocated by the driver. The reallocation happens whenever the IOC Facts change. That should only happen after a firmware upgrade. If the reinitialization happens as a result of a timed out command sent to the card, the command that timed out and triggered the reinit may have been freed if iocfacts_allocate() reallocated all memory. If the caller attempts to access the command after that, the kernel will panic because the caller will be dereferencing freed memory. The solution is to set a flag in the softc when we reallocate, and avoid dereferencing the command strucure if we've reallocated. The changes are largely the same in both drivers, since mpr(4) is a derivative of mps(4). o In iocfacts_allocate(), if the IOC Facts have changed and we need to reallocate, set the REALLOCATED flag in the softc. o Change wait_command() to take a struct mps_command ** instead of a struct mps_command *. This allows us to NULL out the caller's command pointer if we have to reinit the controller and the data structures get reallocated. (The REALLOCATED flag will be set in the softc if that has happened.) o In every place that calls wait_command(), make sure we handle the case where the command is NULL after the call. o The mpr(4) driver has mpr_request_polled() which can also reinitialize the card. Also check for reallocation there. Reviewed by: scottl, slm MFC after: 1 week Sponsored by: Spectra Logic

When the mps(4) and mpr(4) drivers need to reinitialize the firmware, they sometimes need to reallocate all of the memory allocated by the driver. The reallocation happens whenever the IOC Facts change. That should only happen after a firmware upgrade. If the reinitialization happens as a result of a timed out command sent to the card, the command that timed out and triggered the reinit may have been freed if iocfacts_allocate() reallocated all memory.

The solution is to set a flag in the softc when we reallocate, and avoid dereferencing the command strucure if we've reallocated. The changes are largely the same in both drivers, since mpr(4) is a derivative of mps(4). o In iocfacts_allocate(), if the IOC Facts have changed and we need to reallocate, set the REALLOCATED flag in the softc. o Change wait_command() to take a struct mps_command ** instead of a struct mps_command *. This allows us to NULL out the caller's command pointer if we have to reinit the controller and the data structures get reallocated.

/* XXX KDM need to fix the case where this command is destroyed */
- Updated all files with 2015 Avago copyright, and updated LSI's copyright dates. - Changed all of the PCI device strings from LSI to Avago Technologies (LSI). - Added a sysctl variable to control how StartStopUnit behavior works. User can select to spin down disks based on if disk is SSD or HDD. - Inquiry data is required to tell if a disk will support SSU at shutdown or not. Due to the addition of mpssas_async, which gets Advanced Info but not Inquiry data, the setting of supports_SSU was moved to the mpssas_scsiio_complete function, which snoops for any Inquiry commands. And, since disks are shutdown as a target and not a LUN, this process was simplified by basing it on targets and not LUNs. - Added a sysctl variable that sets the amount of time to retry after sending a failed SATA ID command. This helps with some bad disks and large disks that require a lot of time to spin up. Part of this change was to add a callout to handle timeouts with the SATA ID command. The callout function is called mpssas_ata_id_timeout(). (Fixes PR 191348) - Changed the way resets work by allowing I/O to continue to devices that are not currently under a reset condition. This uses devq's instead of simq's and makes use of the MPSSAS_TARGET_INRESET flag. This change also adds a function called mpssas_prepare_tm(). - Some changes were made to reduce code duplication when getting a SAS address for a SATA disk. - Fixed some formatting and whitespace. - Bump version of mps driver to 20.00.00.00-fbsd PR: 191348 Reviewed by: ken, scottl Approved by: ken, scottl MFC after: 2 weeks

/* FIXME */
Merge in phase 14+ -> 16 mps driver fixes from LSI: --------------------------------------------------------------- System panics during a Port reset with ouststanding I/O --------------------------------------------------------------- It is possible to call mps_mapping_free_memory after this memory is already freed, causing a panic. Removed this extra call to mps_mappiing_free_memory and call mps_mapping_exit in place of the mps_mapping_free_memory call so that any outstanding mapping items can be flushed before memory is freed. --------------------------------------------------------------- Correct memory leak during a Port reset with ouststanding I/O --------------------------------------------------------------- In mps_reinit function, the mapping memory was not being freed before being re-allocated. Added line to call the memory free function for mapping memory. --------------------------------------------------------------- Use CAM_SIM_QUEUED flag in Driver IO path. --------------------------------------------------------------- This flag informs the XPT that successful abort of a CCB requires an abort ccb to be issued to the SIM. While processing SCSI IO's, set the CAM_SIM_QUEUED flag in the status for the IO. When the command completes, clear this flag. --------------------------------------------------------------- Check for CAM_REQ_INPROG in I/O path. --------------------------------------------------------------- Added a check in mpssas_action_scsiio for the In Progress status for the IO. If this flag is set, the IO has already been aborted by the upper layer (before CAM_SIM_QUEUED was set) and there is no need to send the IO. The request will be completed without error. --------------------------------------------------------------- Improve "doorbell handshake method" for mps_get_iocfacts --------------------------------------------------------------- Removed call to get Port Facts since this information is not used currently. Added mps_iocfacts_allocate function to allocate memory that is based on IOC Facts data. Added mps_iocfacts_free function to free memory that is based on IOC Facts data. Both of the functions are used when a Diag Reset is performed or when the driver is attached/detached. This is needed in case IOC Facts changes after a Diag Reset, which could happen if FW is upgraded. Moved call of mps_bases_static_config_pages from the attach routine to after the IOC is ready to process accesses based on the new memory allocations (instead of polling through the Doorbell). --------------------------------------------------------------- Set TimeStamp in INIT message in millisecond format Set the IOC --------------------------------------------------------------- --------------------------------------------------------------- Prefer mps_wait_command to mps_request_polled --------------------------------------------------------------- Instead of using mps_request_polled, call mps_wait_command whenever possible. Change the mps_wait_command function to check the current context and either use interrupt context or poll if required by using the pause or DELAY function. Added a check after waiting 50mSecs to see if the command has timed out. This is only done if polliing, the msleep command will automatically timeout if the command has taken too long to complete. --------------------------------------------------------------- Integrated RAID: Volume Activation Failed error message is displayed though the volume has been activated. --------------------------------------------------------------- Instead of failing an IOCTL request that does not have a large enough buffer to hold the complete reply, copy as much data from the reply as possible into the user's buffer and log a message saying that the user's buffer was smaller than the returned data. --------------------------------------------------------------- mapping_add_new_device failure due to persistent table FULL --------------------------------------------------------------- When a new device is added, if it is determined that the device persistent table is being used and is full, instead of displaying a message for this condition every time, only log a message if the MPS_INFO bit is set in the debug_flags.

Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10. Check the actual status of Message unit reset (mps_message_unit_reset).Previously FreeBSD Driver just writes MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack (it just wait for 50 millisecond). So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS. FreeBSD does bus rescan as older Parallel scsi style. So Driver needs to handle which Drive is visible to OS. That is a reason we have to clear off targ information for PDs. Again, above logic was implemented long time ago. Similar concept we have for non-wd also. For that, LSI have introduced different logic to hide PDs. Eventually, because of above gap, when Phy goes offline, we observe below failure. That is what Driver is not doing complete removal of device with FW. (which was pointed by Scott) Apr 5 02:39:24 Freebsd7 kernel: mpslsi0: mpssas_prepare_remove Apr 5 02:39:24 Freebsd7 kernel: mpssas_prepare_remove 497 : invalid handle 0xe Now Driver will not reset target info after port enable complete and also will do Device removal when Device remove from FW. 13. Returning "CAM_SEL_TIMEOUT" instead of "CAM_TID_INVALID" error code on request to the Target IDs that have no devices conected at that moment. As if "CAM_TID_INVALID" error code is returned to the CAM Layaer then it results in a huge chain of errors in verbose kernel messages on boot and every hot-plug event.

Bring in a number of mps(4) driver fixes from LSI: 1. Fixed timeout specification for the msleep in mps_wait_command(). Added 30 second timeout for mps_wait_command() calls in mps_user.c. 2. Make sure we call mps_detach_user() from the kldunload path. 3. Raid Hotplug behavior change. The driver now removes a volume when it goes to a failed state, so we also need to add volume back to the OS when it goes to opitimal/degraded/online from failed/missing. Handle raid volume add and remove from the IR_Volume event. 4. Added some more debugging information. 5. Replace xpt_async(AC_LOST_DEVICE, path, NULL) with mpssas_rescan_target(). This is to work around a panic in CAM that shows up when adding a drive with a rescan and removing another device from the driver thread with an AC_LOST_DEVICE async notification. This problem was encountered in testing with the LSI sas2ircu utility, which was used to create a RAID volume from physical disks. The driver has to create the RAID volume target and remove the physical disk targets, and triggered a panic in the process. The CAM issue needs to be fully diagnosed and fixed, but this works around the issue for now. 6. Fix some memory initialization issues in mps_free_command(). 7. Resolve the "devq freeze forever" issue. This was caused by the internal read capacity command issued in the non-head version of the driver. When the command completed with an error, the driver wasn't unfreezing thd device queue. The version in head uses the CAM infrastructure for getting the read capacity information, and therefore doesn't have the same issue. 8. Bump the version to 13.00.00.00-fbsd.

Bring in LSI's latest mps(4) 6Gb SAS and WarpDrive driver, version 14.00.00.01-fbsd. Their description of the changes is as follows: 1. Copyright contents has been changed in all respective .c and .h files 2. Support for WRITE12 and READ12 for direct-io (warpdrive only) has been added. 3. Driver has added checks to see if Drive has READ_CAP_16 support before sending it down to the device. If SPC3_SID_PROTECT flag is set in the inquiry data, the device supports protection information, and must support the 16 byte read capacity command, otherwise continue without sending read cap 16. This will optimize driver performance, since it will not send READ_CAP_16 to the drive which does not have support of READ_CAP_16. 4. With new approach, "MPTIOCTL_RESET_ADAPTER" IOCTL will not use DELAY() which is busy loop implementation. It will use <msleep> (Better way to sleep without busy loop). Also from the HBA reset code path and some other places, DELAY() is replaced with msleep() or "pause()", which is based on sleep/wakeup style calls. Driver use msleep()/pause() instead of DELAY based on CAN_SLEEP/NO_SLEEP flags to avoid busy loop which is not required all the time.e.a a. While driver is getting loaded, driver calls most of the commands with NO_SLEEP. b. When Driver is functional and it needs Reinit of HBA, CAN_SLEEP flag is used. 5. <mpslsi> driver is not Endian safe. It will not work on Big Endian machines like Sparc and PowerPC platforms because it assumes it is running on a Little Endian machine. Driver code is modified such way that it does not assume CPU arch is Little Endian. a. All places where Driver interacts from HBA to Host, it converts Little Endian format to CPU format. b. All places where Driver interacts from Host to HBA, it converts CPU format to Little Endian. 6. Findout memory leaks in FreeBSD Driver and resolve those, such as memory leak in targ's luns creation/deletion. Also added additional checks to see memory allocation success/fail. 7. Add loginfo prints as debug message, i.e. When FW sends any loginfo, Driver should print those as debug message. This will help for debugging purpose. 8. There is possibility to get config request timeout. Current driver is able to detect config request timetout, but it does not do anything on config_request timeout. Driver should call mps_reinit() if any request_poll (which is called as part of config_request) is time out. 9. cdb length check is required for 32 byte CDB. Add correct mpi control value for 32 bit CDB as below while submitting SCSI IO Request to controller. mpi_control |= 4 << MPI2_SCSIIO_CONTROL_ADDCDBLEN_SHIFT; 10. Check the actual status of Message unit reset (mps_message_unit_reset).Previously FreeBSD Driver just writes MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET and never check the ack (it just wait for 50 millisecond). So, Driver now check the status of "MPI2_FUNCTION_IOC_MESSAGE_UNIT_RESET" after writing it to the FW. Now it also checking for whether doorbell ack uses msleep with proper sleep flags, instead of <DELAY>. 11. Previously CAM does not detect Multi-Lun Devices. In order to detect Multi-Lun Devices by CAM the driver needs following change set: a. There is "max_lun" field which Driver need to set based on hw/fw support. Currently LSI released driver does not set this field. b. Default of "max_lun" should not be 0 in OS, but it is currently set to 0 in CAM layer. c. Export max_lun capacity to 255 12. Driver will not reset target info after port enable complete and also do Device removal when Device remove from FW. The detail description is as follows a. When Driver receive WD PD add events, it will add all information in driver local data structure. b. Only for WD, we have below checks after port enable completes, where driver clear off all information retrieved at #1. if ((sc->WD_available && (sc->WD_hide_expose == MPS_WD_HIDE_ALWAYS)) || (sc->WD_valid_config && (sc->WD_hide_expose == MPS_WD_HIDE_IF_VOLUME)) { // clear off target data structure. } It is mainly not to attach PDs to OS. FreeBSD does bus rescan as older Parallel scsi style. So Driver needs to handle which Drive is visible to OS. That is a reason we have to clear off targ information for PDs. Again, above logic was implemented long time ago. Similar concept we have for non-wd also. For that, LSI have introduced different logic to hide PDs. Eventually, because of above gap, when Phy goes offline, we observe below failure. That is what Driver is not doing complete removal of device with FW.

Bring in a number of mps(4) driver fixes from LSI: 1. Fixed timeout specification for the msleep in mps_wait_command(). Added 30 second timeout for mps_wait_command() calls in mps_user.c. 2. Make sure we call mps_detach_user() from the kldunload path. 3. Raid Hotplug behavior change. The driver now removes a volume when it goes to a failed state, so we also need to add volume back to the OS when it goes to opitimal/degraded/online from failed/missing. Handle raid volume add and remove from the IR_Volume event. 4. Added some more debugging information. 5. Replace xpt_async(AC_LOST_DEVICE, path, NULL) with mpssas_rescan_target(). This is to work around a panic in CAM that shows up when adding a drive with a rescan and removing another device from the driver thread with an AC_LOST_DEVICE async notification. This problem was encountered in testing with the LSI sas2ircu utility, which was used to create a RAID volume from physical disks. The driver has to create the RAID volume target and remove the physical disk targets, and triggered a panic in the process. The CAM issue needs to be fully diagnosed and fixed, but this works around the issue for now. 6. Fix some memory initialization issues in mps_free_command(). 7. Resolve the "devq freeze forever" issue. This was caused by the internal read capacity command issued in the non-head version of the driver. When the command completed with an error, the driver wasn't unfreezing thd device queue. The version in head uses the CAM infrastructure for getting the read capacity information, and therefore doesn't have the same issue. 8. Bump the version to 13.00.00.00-fbsd. (this is very close to LSI's internal stable driver 13.00.00.00) Submitted by: Kashyap Desai <Kashyap.Desai@lsi.com> MFC after: 3 days

Changes to make mps(4) and mpr(4) handle reinit with reallocation. When the mps(4) and mpr(4) drivers need to reinitialize the firmware, they sometimes need to reallocate all of the memory allocated by the driver. The reallocation happens whenever the IOC Facts change. That should only happen after a firmware upgrade. If the reinitialization happens as a result of a timed out command sent to the card, the command that timed out and triggered the reinit may have been freed if iocfacts_allocate() reallocated all memory. If the caller attempts to access the command after that, the kernel will panic because the caller will be dereferencing freed memory. The solution is to set a flag in the softc when we reallocate, and avoid dereferencing the command strucure if we've reallocated. The changes are largely the same in both drivers, since mpr(4) is a derivative of mps(4). o In iocfacts_allocate(), if the IOC Facts have changed and we need to reallocate, set the REALLOCATED flag in the softc. o Change wait_command() to take a struct mps_command ** instead of a struct mps_command *. This allows us to NULL out the caller's command pointer if we have to reinit the controller and the data structures get reallocated. (The REALLOCATED flag will be set in the softc if that has happened.) o In every place that calls wait_command(), make sure we handle the case where the command is NULL after the call. o The mpr(4) driver has mpr_request_polled() which can also reinitialize the card. Also check for reallocation there. Reviewed by: scottl, slm MFC after: 1 week Sponsored by: Spectra Logic
