* [SCSI] mptfusion: Block Error handling for deleting devices or Device in DMDKashyap, Desai2010-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue description: In multipath topology, when device deletion is in transient state, multipath driver can call blk_flush_queue() as part of path failure. Before device get deleted from OS, Device may go OFFLINE as part of error handling kicked off triggered from multipathing driver. Above condition hits more frequently if device missing delay timer (which is LSI specific firmware parameter) is non zero value. root cause of this issue is Error handling thread is getting kicked off for device which is not really present(in transient state of deleting). This patch has solution for this issue. driver is now using eh_timed_out callback. See below. mptsas_transport_template->eh_timed_out = mptsas_eh_timed_out Using mptsas_eh_timed_out function, driver can decide weather vdevice is under Device missing delay or deleting state. for either of those cases, there is BLK_EH_RESET_TIMER return to scsi mid and error handling thread will not be kicked off for that particular scsi command.

* [SCSI] mptfusion: schedule_target_reset from all Reset contextKashyap, Desai2010-07-27
| | | | | | | | | | | | | | | | | Issue: target reset will be queued to driver's internal queue to get schedule later. When driver add target into internal target_reset queue we will block IOs on those target using scsi midlayer API. Now due to some cause driver is not executing those target_reset list and it is always in block state. Changes: now we are clearing target_reset queue from all other Callback context instead of only DeviceReset context.Now wherever driver is clearing taskmgmt_in_progress flag it is considering target_reset queue cleanup also.

* [SCSI] mptfusion: Added new less expensive RESET (Message Unit Reset)Kashyap, Desai2010-04-11
| | | | | | | | | | | | | | | | Message Unit Reset - instructs the IOC to reset the Reply Post and Free FIFO's. All the Message Frames on Reply Free FIFO are discarded. All posted buffers are freed, and event notification is turned off. IOC doesnt reply to any outstanding request. This will transfer IOC to READY state. Message unit ready is less expensive operations than Hard Reset. soft reset will not force Firmware to reload again, it only do clean up of Message units. mpt_Soft_Hard_ResetHandler will first try for Soft Reset,if it fails then go for big hammer reset which is Hard Reset.

* [SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory regionKashyap, Desai2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The reason for this change is there is a data corruption when four different physical memory regions in the 36GB to 37GB region are accessed. This is only affecting 1078. The solution is we need to use different addressing when filling in the scatter gather table for the effected memory regions. So instead of snooping on all four different memory holes, we treat any physical addresses in the 36GB address with the same algorithm. The fix is explained below 1) Ensure that the message frames are NOT located in the trouble region. There is no remapping available for message frames, they must be allocated outside the problem region. 2) Ensure that Sense buffers are NOT in the trouble region. There is no remapping available. 3) Walk through the SGE entries and if any are inside the trouble region then they need to be remapped as discussed below. 1) Set the Local Address bit in the SGE Flags field. MPI_SGE_FLAGS_LOCAL_ADDRESS 2) Ensure we are using 64-bit SGEs 3) Set MSb (Bit 63) of the 64-bit address, this will indicate buffer location is Host Memory.

* [SCSI] mptsas: do not use ioc->handle to locate hba portinfo structureMichael Reed2008-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | While performing hardware raid reset testing via the raid's client, I noticed that sometimes, following the reset, that there would be more raid targets in the lsscsi output than there actually were raid targets. I tracked this down to the following issue. Fusion cannot always find the mptsas_portinfo structure for the hba because it uses the handle stored in ioc->handle to locate it. The problem is that the firmware can change the handle associated with the hba when h/w raid is reset (via the raid client). When this happens, the driver will allocate another mptsas_portinfo structure and link it into the chain of said structures. This ultimately causes confusion within the driver resulting in targets not being removed when they should be. Eric Moore pointed out that the hba's portinfo structure is always the first structure on the sas_topology list. This patch modifies mptsas.c to access the hba's portinfo structure by taking the first structure on said list.
