Subject: [scsi] fusion: update mpt driver to 3.4.13rh
Message-id: <20091120163043.3150.37185.sendpatchset@localhost.localdomain>
Patchwork-id: 21456
O-Subject: [RHEL5.5 PATCH] bz
Bugzilla: 516710
RH-Acked-by: Pete Zaitcev <zaitcev@redhat.com>
This is for bz#516710
This patch comes from LSI - Kashyap Desai
It updates our driver to 3.4.13rh.
Version 3.4.13 is in upstream scsi-misc tree.
Commenst from LSI:
1. Previously we had mutliple #defines to use same values.
Now those #defines are optimized.
MPT_IOCTL_STATUS_* is removed and MPT_MGMT_STATUS_* are new
#defines.
2. config path is optimized. Instead of wait Queue and timer, using
completion Q.
3. mpt_timer_expired is not used.
4. Rewrite of all internal generated functions that issue commands to
firmware,porting them to be single threaded using the generic MPT_MGMT
struct. Implemented using completion Queue.
5. rewrite taskmanagement request and completion routines, making them
single threaded and using the generic MPT_MGMT struct, deleting
mptscsih_TMHandler, replacing with single request TM handler
mptscsih_IssueTaskMgmt, and killing the watchdog timer functions.
6. cleanup ioc_reset callback handlers, introducing wrappers for
synchronizing error recovery (mpt_set_taskmgmt_in_progress_flag,
mpt_clear_taskmgmt_in_progress_flag), as the fusion firmware only
handles one task management request at a time.
7. Added taskmgmt_quiesce_io flag in IOC and removed resetPending from
_MPT_SCSI_HOST struct.
8. Reset from Scsi mid layer and internal Reset are seperate context.
Adding DeviceResetCtx for internal Device reset frame.
mptsas_taskmgmt_complete is optimized as part of implementation.
9. rewrite of ioctl_cmds internal generated function that issue
commands to firmware, porting them to be single threaded using the
generic MPT_MGMT struct. All wait Queues are replace by completion
Queue.
10. added seperate callback handler for ioctl task managment
(mptctl_taskmgmt_reply), to handle command that timeout
11.rewrite mptctl_bus_reset.
12. Now Firmware events are handled by firmware event queue.
Previously it was handled in interrupt context/WorkQueue of Linux.
Firmware Event handling is restructured and optimized.
13. SAS topology scan is restructured. HBA firmware is generating more
events. Expander Events are added, Link status events are also added
with respect to SAS topology scan optimization.
14. Put IOC into ready state if it not already in ready state.
15. FW will report Queue full event to Driver and driver will handle
this queue full event to SCSI Mid layer.
16. Firmware is able to handle Broadcast primitives, but upstream
driver does not have support for broadcast primitive handling. Now
this patch is mainly to support broadcast primitives.
17. Handle integrated Raid device(Add/Delete) and error condition and
check related to Raid device. is_logical_volume will represent logical
volume device.
18. Raid device dual port support is added. Main functions to support
this feature are mpt_raid_phys_disk_get_num_paths and
mpt_raid_phys_disk_pg1
19.The driver is modified to return DID_NO_CONNECT for all pending I/O
requests for a particular target, if it founds the target is removed
at the firmware level.
20. New sysfs attributes are added to assist the MPT firmware
debugging added support for fetching information for the sysfs
attributes provided by transport layer in the sas_expander class.
21. Big endian systems causing Expanders not to tear off
22.Fix for Different SAS address received for some SATA devices
23. Fix for SAS cable pulls and reinsertions causing problems
intermittently
24. Mptctl incorrectly checks the function type on a bus reset call.
25. Code cleanup to match driver with our latest upstream.
26. Target remains in blocking state fix.
27. Fix for Diag buffer registration fails after HBA reset.
I've verified basic functionality(it boots + some i/o test)
on PAE and x86-64 system.
