Author: ken Date: Sun Jul 1 05:22:45 2012 New Revision: 237876 URL: http://svn.freebsd.org/changeset/base/237876 Log: MFC 237683: r237683 | ken | 2012-06-27 21:48:54 -0600 (Wed, 27 Jun 2012) | 129 lines 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.
