* Merge r268024, 268025:scottl2014-07-011-0/+1
| | | | | | | | | | | | | | | | | | Fix a case in ndling ATA_PASSTHROUGH commands that have an unaligned buffer. This impacts some home-rolled SMART tools. In rare cases, a SATA drive can stop responding to commands and trigger a reset device task request from the driver. If the drive fails to respond with a signature FIS, the driver would previously get into an endless retry loop, stalling all I/O to the drive and keeping user processes stranded. Instead, fail the i/o and invalidate the device if the task management command times out. This is controllable with the sysctl and tunable hw.isci.fail_on_task_timeout dev.isci.0.fail_on_task_timeout The default for these is 1. Obtained from: Netflix, Inc.

* For ATA_PASSTHROUGH commands, pretend isci(4) supports multiword DMAjimharris2013-06-261-4/+45
| | | | | | | | | | | | | | | | | | | | | | | by treating it as UDMA. This fixes a problem introduced in r249933/r249939, where CAM sends ATA_DSM_TRIM to SATA devices using ATA_PASSTHROUGH_16. scsi_ata_trim() sets protocol as DMA (not UDMA) which is for multi-word DMA, even though no such mode is selected for the device. isci(4) would fail these commands which is the correct behavior but not consistent with other HBAs, namely LSI's. smh@ did some further testing on an LSI controller, which rejected ATA_PASSTHROUGH_16 commands with mode=UDMA_OUT, even though only a UDMA mode was selected on the device. So this precludes adding any kind of mode detection in CAM to determine which mode to use on a per-device basis.

* isci(4): Fix SCSI/ATA translation for SCSI_WRITE_BUFFER w/ mode==0x7jimharris2012-09-142-7/+14
| | | | | | | | | | | | | | (download microcode with offsets, save, and activate). SATI translation layer was incorrectly using allocation length instead of blocks, and was constructing the ATA command incorrectly. Also change #define to specify that the 512 block size here is specific for DOWNLOAD_MICROCODE, and does not relate to the device's logical block size.

* Do not call sati_check_data_io() for SATI_UNMAP sequences.jimharris2012-08-301-4/+0
| | | | | | | | | | | | This routine is intended only for commands such as INQUIRY where the controller may fill out a smaller amount of data than allocated by the host. The end result of this bug was that isci(4) would report non-zero resid for successful SCSI_UNMAP commands. Sponsored by: Intel MFC after: 3 days
* Fix/add support for SCSI UNMAP to ATA DSM translation.jimharris2012-08-213-11/+6
| | | | | | | | | | | | | | | | | | This addresses kernel panic observed when sending SCSI UNMAP commands to SATA disks attached to isci(4). 1) Flesh out callback routines to allocate/free buffers needed for translating SCSI UNMAP data to ATA DSM data. 2) Add controller-level pool for storing buffers previously allocated for UNMAP translation, to lessen chance of no buffer available under memory pressure. 3) Ensure driver properly handles case where buffer pool is empty and contigmalloc returns NULL.
