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: NJames Bottomley <James.Bottomley@SteelEye.com>

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.

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: NDarrick J. Wong <djwong@us.ibm.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

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: NDarrick J.

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.

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: NDarrick J.

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: NDarrick J.

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: NJames Bottomley <James.Bottomley@SteelEye.com>

This patch adds SATAII NCQ support to libsas. Both the use_ncq and the dma_xfer flags in ata_task must be set for NCQ to work correctly on the Adaptec SAS controller. The rest of the patch adds ATA_FLAG_NCQ to sata_port_info and sets up ap->scsi_host so that ata_setup_ncq doesn't crash. Please note that this patch is against the aic94xx-sas git tree, not scsi-misc. Thanks also to James Bottomley for providing an earlier version of this patch from which to work. I've tested this patch on a x206m with a ST380819AS SATA2 disk plugged into the Adaptec SAS controller. The drive came up with a queue depth of 31, and I successfully ran an I/O flood test to coerce libata into sending multiple commands simultaneously. A kernel probe recorded the maximum tag number that had been seen before and after the flood test; before the test it was 2 and after it was 30, as I expected. Signed-off-by: NDarrick J.

The aic94xx controller has a bitmask establishing which tags are ok to use with a SATA NCQ disk. When the queue depth is 32, however, the expression that is used sets the mask to zero, not 0xFFFFFFFF. This patch widens the width of the integer so that this case is handled properly.

This patch adds support for SATA over SAS expanders to the previous two SATA support in libsas patches. There were a couple of nasty non trivial things to sort out before this one could be made to work. Firstly, I'd like to thank Doug Gilbert for diagnosing a problem with the LSI expanders where the REPORT_SATA_PHY command was returning the D2H FIS in the wrong order (Although, here, I think I have to blame the SAS standards which specifies the FIS "shall be returned in little endian format" and later on "which means resp[24] shall be FIS type" The latter, of course, implying big endian format). Just to make sure, I put a check for the D2H FIS type being in the wrong position and reverse the FIS data if it is. The second is a problem outlined in Annex G of the SAS standard (again, a technical point with D2H FIS ... necessitating a phy reset on certain conditions). With the patch, I can now see my SATA-1 disk in a cascaded expander configuration. Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

This is a reimplementation of the zs driver for the serial subsystem. Any resemblance to the old driver is purely coincidential. ;-) I do hope I got the handling of modem lines right -- better do not tackle me about the issue unless you feel too good... Any users of the old driver: please note the numbers of the serial lines have now been swapped, i.e. ttyS0 <-> ttyS1 and ttyS2 <-> ttyS3. It has to do with the modem lines mentioned above; basically the port A in a given chip has to be initialised before the port B if you want to use the latter as the serial console (which is usually the case), as operations on modem lines of the serial line associated with the port B access both ports (see the comment at the top of the driver for the details of wiring used). Please update your scripts. This is also the reason each SCC now requests an IRQ once only (as seen in "/proc/interrupts") -- the handler takes care of both ports at once as the line associated with the port B has to take status update interrupts from both ports (and yet the line of the port A takes its own for itself too). The old driver never got it right... Signed-off-by: NMaciej W.
