2008-02-24[SCSI] aic94xx: fix TMF ascb handling to prevent sequencer panicJames Bottomley
This is a particularly nasty bug. The problem is that if any internal ascb times out, currently we free it even though it's pending at the sequencer. This results in the sequencer getting terminally confused and the error message: BUG:sequencer:dl:no ascb Being returned when it comes back. The way to fix this is to manage freeing the ascb from the tasklet completion routine, so that we only free it when the sequencer actually returns it. The code is also altered to use on stack completions and transfer variables. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2008-02-23[SCSI] aic94xx: plumb in I_T_nexus_reset task management functionJames Bottomley
Currently aic94xx has no exported I_T_nexus_reset function. This is a bit of a huge problem, since sas_ata relies on this function to perform an ATA phy reset and also it means that if abort fails, we really have no bigger hammer to hit everything with. Plumb in the I_T_nexus_reset by quiescing the sequencer, sending the correct phy reset (link for ATA and hard for SAS) and then carefully resuming the sequencer again.

2008-02-22[SCSI] aic94xx: fix sequencer hang on error recoveryJames Bottomley
The clear nexus I_T and clear nexus I_T_L functions in the aic94xx specify the SUSPEND_TX flag which causes the sequencer to be suspended until it receives a RESUME_TX. Unfortunately, nothing ever sends the resume, so the sequencer on the link is stopped forever, leading to eventual timeouts and I/O errors. Since clear nexus commands are only executed as part of error recovery, it's perfectly fine to keep the sequencer running on the link ... as soon as the recovery function is completed, we'll send it the commands to retry.

2008-02-18[SCSI] aic94xx: fix REQ_TASK_ABORT and REQ_DEVICE_RESETJames Bottomley
This driver has been failing under heavy load with aic94xx: escb_tasklet_complete: REQ_TASK_ABORT, reason=0x6 aic94xx: escb_tasklet_complete: Can't find task (tc=4) to abort! The second message is because the driver fails to identify the task it's being asked to abort. On closer inpection, there's a thinko in the for each task loop over pending tasks in both the REQ_TASK_ABORT and REQ_DEVICE_RESET cases where it doesn't look at the task on the pending list but at the one on the ESCB (which is always NULL). Fix by looking at the right task. Also add a print for the case where the pending SCB doesn't have a task attached. Not sure if this will fix all the problems, but it's a definite first step.

2007-07-18[SCSI] libsas, aic94xx: fix dma mapping cockups with ATAJames Bottomley
This one was noticed by Gilbert Wu of Adaptec: The libata core actually does the DMA mapping for you, so there has to be an exception in the device drivers that *don't* do dma mapping for ATA commands. However, since we've already done this, libsas must now dma map any ATA commands that it wishes to issue ... and yes, this is a horrible mess. Additionally, the test in aic94xx for ATA protocols isn't quite right. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-07-18[SCSI] aic94xx: Don't call pci_map_sg for already-mapped scatterlistsDarrick J. Wong
It turns out that libata has already dma_map_sg'd the scatterlist entries that go with an ata_queued_cmd by the time it calls sas_ata_qc_issue. sas_ata_qc_issue passes this scatterlist to aic94xx. Unfortunately, aic94xx assumes that any scatterlist passed to it needs to be pci_map_sg'd... which blows away the mapping that libata created! This causes (on a x260) Calgary IOMMU table leaks and duplicate frees when aic94xx and libata try to {pci,dma}_unmap_sg the scatterlist. Signed-off-by: Darrick J.

2007-07-18[SCSI] libsas: fixup NCQ for SATA disksJames Bottomley
We actually had two problems: the one with the tag (which is fixed by zeroing the tag before sending the taskfile to the sequencer) but the other with the fact that we sent our first NCQ command to the device before the sequencer had been informed of the NCQ tagging capabilities. I fixed the latter by moving the rphy_add() to the correct point in the code after the NCQ capabilities are set up. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-07-18[SCSI] aic94xx: SATA tag mask not set correctlyDarrick J. Wong

2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance. Compile tested with make all{yes,mod}config on x86_64 and i386.

2007-05-22[SCSI] aic94xx: asd_clear_nexus should fail if the cleared task does not ↵Darrick J. Wong
complete Every so often, the driver will call asd_clear_nexus to clean out a task. It is supposed to be the case that the CLEAR NEXUS does not go on the done list until after the task itself has been put on the done list, but for some reason this doesn't always happen. Thus, the wait_for_completion_timeout call times out, and we return success. This makes libsas free the task even though the task hasn't completed, leading to a BUG_ON message from aic94xx_hwi.c around line 341. We should return failure from asd_clear_nexus so that libsas tries again; at a bare minimum it shouldn't be freeing active tasks. I _think_ this will fix one of the SCB timeout crash problems (though I've not been able to reproduce it lately...) Signed-off-by: Darrick J.

I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually.

The sequencer firmware file has both a string (currently showing V17/10c6) and a number (currently set to 1.1). It has become apparent that Adaptec may issue sequencer firmware in the future which could be incompatible with the current driver. Therefore, the driver will be tied to the particular major number of the firmware (i.e. the current driver will load any 1.x firmware).

2007-02-03[SCSI] aic94xx: Remove TMF result code mungingDarrick J. Wong
In asd_initiate_ssp_tmf, the TMF result code is replaced with TMF_RESP_FUNC_FAILED except when the TMF returns a result code immediately. However, TMFs can return result codes via an ESCB... yet these codes are also replaced with "FAILED". The only values that can fall into that case are TMF_* codes anyway, so get rid of this code where COMPLETE and SUCCESS are turned into FAILED. This also lets us propagate those TMF_* codes up to the caller. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2007-01-13[SCSI] aic94xx: Lock DDB read/write accessesDarrick J. Wong
Extend the use of the DDB lock to include all DDB accesses, because DDB updates now occur from multiple threads. This fixes the SMP timeout problems that we were occasionally seeing with a x260, because the controller got confused when the DDBs got corrupted. Signed-off-by: Darrick J.

2007-01-13[SCSI] aic94xx: Fix DDB and SCB initializationDarrick J. Wong
Ed Chim of Adaptec informs us that the DDB registers need to be zeroed at initialization time and that some SCB initializations need to happen even if we don't use the SCB. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

The vmalloc() blob holding the sequencer firmware wasn't being released at module unload time, which resulted in a memory leak. Signed-off-by: Alexis Bruemmer <alexisb@us.ibm.com> Acked-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-01-13[SCSI] aic94xx: Remove workqueue code from REQ_TASK_ABORT/REQ_DEVICE_RESET codeDarrick J. Wong
Now that task aborts and device port resets are done by the EH, we can remove all the code that set up workqueues and such and simply call sas_task_abort and let libsas figure things out. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-01-13[SCSI] aic94xx: Don't eat TMF_QUERY_TASK resultsDarrick J. Wong
In this driver, TMF_QUERY_TASK translates to QUERY_SSP_TASK. The sequencer, it seems, is perfectly happy sending us a SSP response, which this function promptly "converts" into TMF_RESP_FUNC_FAILED. This leads to the SAS EH making bad decisions based on bad data, so we should not perform the conversion in this case. Signed-off-by: Darrick J.

2007-01-13[SCSI] aic94xx: Set lldd_max_execute_num in sas_haDarrick J. Wong
The aic94xx module has a parameter that looks like it should set lldd_max_execute_num in the sas_ha, but it never sets this value. Either we should set it or remove the parameter. This allows us to enable task collector mode for this driver, though it is still off by default. Signed-off-by: Darrick J.
