2009-12-04[SCSI] modify change_queue_depth to take in reason why it is being calledMike Christie
This patch modifies scsi_host_template->change_queue_depth so that it takes an argument indicating why it is being called. This will be used so that if a LLD needs to do some extra processing when handling queue fulls or later ramp ups, it can do so. This is a simple port of the drivers setting a change_queue_depth callback. In the patch I just have these LLDs adjust the queue depth if the user was requesting it. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> [Vasu.Dev: v2 Also converted pmcraid_change_queue_depth and then verified all modules compile using "make allmodconfig" for any new build warnings on X86_64.

2009-10-29[SCSI] mptspi: Fix for incorrect data underrun errataKashyap, Desai
Errata: Certain conditions on the scsi bus may casue the 53C1030 to incorrectly signal a SCSI_DATA_UNDERRUN to the host. Workaround 1: For an Errata on LSI53C1030 When the length of request data and transfer data are different with result of command (READ or VERIFY), DID_SOFT_ERROR is set. Workaround 2: For potential trouble on LSI53C1030. It is checked whether the length of request data is equal to the length of transfer and residual. MEDIUM_ERROR is set by incorrect data.

2009-06-09[SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory regionKashyap, Desai
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.

2008-12-16[SCSI] mpt fusion: clear list of outstanding commands on host resetJames Bottomley
A bug in the fusion driver was exposed by the switch to block timeout. Basically, drivers are supposed to terminate commands once error handling begins on them. The fusion apparently wasn't doing this. Under the old timeout regime, completions on terminated commands would by and large get ignored because of the way command timeouts used to work. The new block timers are very intolerant to this, though, becuase the request gets cleaned and freed.

2008-05-27[SCSI] fusion mpt: fix target missing after resetting external raidMichael Reed
Following a hard reset of a SAS raid, one of the raid targets is occasionally missing. I tracked this down to a pretty obscure little bug. The LSI fusion drivers for SAS and Fibre Channel both use their respective transport layers. Those transport layers increment the target number assigned to new targets. The routine __scsi_scan_target uses the "this_id" element of the Scsi_Host structure to avoid scanning the scsi host adapter. Both fusion drivers set "this_id" from a value returned in a firmware PortFacts response. For my particular test case (SAS) the firmware id assigned to the initiator was 173. After enough raid resets to cause the raid targets to go and come a sufficient number of times, the id assigned by the transport to a raid target would match the id assigned by the host adapter to the "this_id" field, resulting in that target not being scanned. Fix by not assigning this_id and not checking it in slave_configure.

2007-06-17[SCSI] mpt fusion: fix for mounted raid volume filesytem that goes read-onlyEric Moore
If there is IO going to the volume while a hidden disk is being torn down, there is a case where we would return a DID_NO_CONNECT for IO sent to the volume. The end result is the volume goes read-only. This problem is due to the fact the firmware mapped target ids saved in per device object is phys_disk_num for hidden raid components, and target_id for the volume. There is a single case when both phys_disk_num and target_id are equal, so enters this issue. We fix this issue by checking the tflags when the device is torned down, insuring the IO being completed is meant for hidden raid component, not the volume. In addition to this fix, there are a couple other cases to address hidden raid components. For instance task_abort and device reset are not supported by mpt fw for hidden raid components, a bus reset would be required or target reset to volume.
