Merge branch 'for-4.7-zac' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2016-05-24T00:53:39Z

Pull libata ZAC support from Tejun Heo: "This contains Zone ATA Command support for Shingled Magnetic Recording devices. In addition to sending the new commands down to the device, as ZAC commands depend on getting a lot of responses from the device, piping up responses is beefed up too. However, it doesn't involve changes to libata core mechanism or its interaction with upper layers, so I'm not expecting too many fallouts. Kudos to Hannes for driving SMR support" * 'for-4.7-zac' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (28 commits) libata: support host-aware and host-managed ZAC devices libata: support device-managed ZAC devices libata: NCQ encapsulation for ZAC MANAGEMENT OUT libata: Implement ZBC OUT translation libata: implement ZBC IN translation libata: fixup ZAC device disabling libata-scsi: Generate sense code for disabled devices libata-trace: decode subcommands libata: Check log page directory before accessing pages libata: Add command definitions for NCQ Encapsulation for READ LOG DMA EXT libata: Separate out ata_dev_config_ncq_send_recv() libata/libsas: Define ATA_CMD_NCQ_NON_DATA libsas: enable FPDMA SEND/RECEIVE libata: do not attempt to retrieve sense code twice libata-scsi: Set information sense field for invalid parameter libata-scsi: set bit pointer for sense code information libata-scsi: Set field pointer in sense code scsi: add scsi_set_sense_field_pointer() libata: Implement control mode page to select sense format libata-scsi: generate correct ATA pass-through sense ...

libata: support host-aware and host-managed ZAC devices

2016-05-09T16:36:46Z

Byte 69 bits 0:1 in the IDENTIFY DEVICE data indicate a host-aware ZAC device. Host-managed ZAC devices have their own individual signature, and to not set the bits in the IDENTIFY DEVICE data. And whenever we detect a ZAC-compatible device we should be displaying the zoned block characteristics VPD page. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: support device-managed ZAC devices

2016-05-09T16:36:46Z

Device-managed ZAC devices just set the zoned capabilities field in INQUIRY byte 69 (cf ACS-4). This corresponds to the 'zoned' field in the block device characteristics VPD page. As this is only defined in SPC-5/SBC-4 we also need to update the supported SCSI version descriptor.

libata: NCQ encapsulation for ZAC MANAGEMENT OUT

2016-05-09T16:36:46Z

Add NCQ encapsulation for ZAC MANAGEMENT OUT and evaluate NCQ Non-Data log pages to figure out if NCQ encapsulation is supported. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: Implement ZBC OUT translation

2016-05-09T16:36:46Z

ZAC drives implement a 'ZAC Management Out' command template, which maps onto the ZBC OUT command. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: implement ZBC IN translation

2016-05-09T16:36:46Z

ZAC drives implement a 'ZAC Management In' command template, which maps onto the ZBC IN command. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata-trace: decode subcommands

2016-05-09T16:36:45Z

Some commands like FPDMA RECEIVE or NCQ NON DATA can encapsulate other commands to NCQ transport. So decode the subcmds, too. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: Check log page directory before accessing pages

2016-05-09T16:36:45Z

When reading the NCQ Send/Recv log it might actually not supported, thereby causing irritating messages 'READ LOG DMA EXT failed'. Instead we should be reading the log directory first to figure out if the log is actually supported before trying to access it. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: Add command definitions for NCQ Encapsulation for READ LOG DMA EXT

2016-05-09T16:36:45Z

ACS-4 defines an NCQ encapsulation for READ LOG DMA EXT. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo
