This patch moves the bsg registration into SCSI so that bsg no longer has a dependency on the scsi_interface_register API. This can be viewed as a temporary expedient until we can get universal bsg binding sorted out properly. Also use the sdev bus_id as the generic bsg name (to avoid clashes with the queue name).

Fix drivers misusing dev_to_shost Some drivers were using dev_to_shost to go from a struct device to the corresponding shost. Unfortunately, dev_to_shost only looks up the tree to find an shost (it's designed to go from a scsi_device or a scsi_target to the parent scsi_host), and these drivers were calling it with the parent of the scsi_host. I've fixed this by saving a pointer to the Scsi_Host in the drvdata, which matches what most scsi drivers do. Signed-off-by:

Report VPD inquiry page 0x80 with an unique array creation serial number (CUID). When an array is created, the metadata stored on the physical drives gets an unique serial number. This serial number remains constant through array morphing or migration to other controllers. This patch is a forward port and modification to survive morphing and migration operations, of a similar piece of (un-attributed author) code added to the SLES10 SP1 aacraid driver. To test the results of the patch, observe that /dev/disk/by-id/ entries will show up for the arrays resulting from the udev rules. Also, as per the udev rules, 'scsi_id -g -x -a -s /block/sd? -d /dev/sd?' will report the ID_SERIAL as constructed from the inquiry data. It was reported to me that the 'ADPT' leading the serial number was bad form, that the inquiry vendor field was enough to differentiate the storage uniquely. Subsequent search found that another Adaptec AAC based driver reported the 8 hex serial number only without such adornments, so dropped ADPT to match. Resubmitting the patch with this alteration.

Incorrect dma mask was used for blinkled (firmware assert) recovery or user initiated reset during initialization portion. Ensure that all callers of aac_fib_map_free null out the fib allocation references to prevent multiple free. Although serious sounding, no reports of these problems have surfaced... Signed-off-by:

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: -

ATA devices need special handling for sas_task_abort. If the ATA command came from SCSI, then we merely need to tell SCSI to abort the scsi_cmnd. However, internal commands require a bit more work--we need to fill the qc with the appropriate error status and complete the command, and eventually post_internal will issue the actual ABORT TASK. Signed-off-by: -

The SATL should connect the scsi_cmnd to the sas_task (despite the presence of libata) so that requests to abort scsi_cmnds headed to the ATA device can be processed by the EH and aborted correctly. The abort status should still be propagated from sas -> ata -> scsi. Signed-off-by:

Since the aic94xx sequencer assigns its own NCQ tags to ATA commands, it no longer makes any sense to copy the sactive field in the STP response to ata_port->sactive, as that will confuse libata. Also, libata seems to be capable of managing sactive on its own. The attached patch gets rid of one of the causes of the BUG messages in ata_qc_new, and seems to work without problems on an IBM x206m. Signed-off-by:

This patch adds a new field, lldd_task, to ata_queued_cmd so that libata users such as libsas can associate some data with a qc. The particular ambition with this patch is to associate a sas_task with a qc; that way, if libata decides to timeout a command, we can come back (in sas_ata_post_internal) and abort the sas task. One question remains: Is it necessary to reset the phy on error, or will the libata error handler take care of it? (Assuming that one is written, of course.) This patch, as it is today, works well enough to clean things up when an ATA device probe attempt fails halfway through the probe, though I'm not sure this is always the right thing to do.

The sas_ata_qc_issue function was incorrectly written to return error codes such as -ENOMEM. Since libata OR's qc->err_mask with the return value, It is necessary to make my code return one of the AC_ERR_ codes instead. For now, use AC_ERR_SYSTEM because an error here means that the OS couldn't send the command to the controller. If anybody has a suggestion for a better AC_ERR_ code to use, please suggest it.

ata_qc_complete and ata_sas_queuecmd require that the port lock be held when they are called. sas_ata doesn't do this, leading to BUG messages about qc tags newly allocated qc tags already being in use. This patch fixes the locking, which should clean up the rest of those messages. So far I've tested this against an IBM x206m with two SATA disks with no BUG messages and no other signs of things going wrong, and the machine finally passed the pounder stress test. Signed-off-by:

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: -

This is a respin of my earlier patch that migrates the ATA support code into a separate file. For now, the controversial linking bits have been removed per James Bottomley's request for a patch that contains only the migration diffs, which means that libsas continues to require libata. I intend to address that problem in a separate patch. This patch is against the aic94xx-sas-2.6 git tree, and it has been sanity tested on my x206m with Seagate SATA and SAS disks without uncovering any new problems. Signed-off-by:

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:
