2009-06-09[SCSI] mpt fusion: Fixing 1078 data corruption issue for 36GB memory regionKashyap, Desai1-10/+8
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.

2009-05-19block: set rq->resid_len to blk_rq_bytes() on issueTejun Heo1-1/+2
In commit c3a4d78c580de4edc9ef0f7c59812fb02ceb037f, while introducing rq->resid_len, the default value of residue count was changed from full count to zero. The conversion was done under the assumption that when a request fails residue count wasn't defined. However, Boaz and James pointed out that this wasn't true and the residue count should be preserved for failed requests too. This patchset restores the original behavior by setting rq->resid_len to blk_rq_bytes(rq) on request start and restoring explicit clearing in affected drivers. While at it, take advantage of the fact that rq->resid_len is set to full count where applicable. * ide-cd: rq->resid_len cleared on pc success * mptsas: req->resid_len cleared on success * sas_expander: rsp/req->resid_len cleared on success * mpt2sas_transport: req->resid_len cleared on success * ide-cd, ide-tape, mptsas, sas_host_smp, mpt2sas_transport, ub: take advantage of initial full count to simplify code Boaz Harrosh spotted bug in resid_len initialization.

2009-05-11block: add rq->resid_lenTejun Heo1-2/+1
rq->data_len served two purposes - the length of data buffer on issue and the residual count on completion. This duality creates some headaches. First of all, block layer and low level drivers can't really determine what rq->data_len contains while a request is executing. It could be the total request length or it coulde be anything else one of the lower layers is using to keep track of residual count. This complicates things because blk_rq_bytes() and thus [__]blk_end_request_all() relies on rq->data_len for PC commands. Drivers which want to report residual count should first cache the total request length, update rq->data_len and then complete the request with the cached data length. Secondly, it makes requests default to reporting full residual count, ie. reporting that no data transfer occurred. The residual count is an exception not the norm; however, the driver should clear rq->data_len to zero to signify the normal cases while leaving it alone means no data transfer occurred at all. This reverse default behavior complicates code unnecessarily and renders block PC on some drivers (ide-tape/floppy) unuseable. This patch adds rq->resid_len which is used only for residual count. While at it, remove now unnecessasry blk_rq_bytes() caching in ide_pc_intr() as rq->data_len is not changed anymore.

2008-05-27[SCSI] fusion mpt: fix target missing after resetting external raidMichael Reed1-2/+0
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.

2008-04-07[SCSI] mptsas: do not use ioc->handle to locate hba portinfo structureMichael Reed1-5/+17
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.

2007-03-11[SCSI] mptsas: Fix oops for insmod during kexecJudith Lebzelter1-2/+5
This fix's an oops during driver load time. mptsas_probe calls mpt_attach(over in mptbase.c). Inside that call, we read some manufacturing config pages to setup some defaults. While reading the config pages, the firmware doesn't complete the reply in time, and we have a timeout. The timeout results in hardreset handler being called. The hardreset handler calls all the fusion upper layer driver reset callback handlers. The mptsas_ioc_reset function is the callback handler in mptsas.c. So where I'm getting to, is mptsas_ioc_reset is getting called before scsi_host_alloc is called, and the pointer ioc->sh is NULL as well as the hostdata.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+1
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

Current implementation does the target resets from delayed work tasks, that in heavy load conditions, take too long to be invoked, resulting in command time outs This patch will issue target reset immediately from ISR context, and will queue remaining target resets to be issued after the previous one completes. The delayed work tasks are spawned during the target reset completion. Signed-off-by: Eric Moore <Eric.Moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
