ata: ATA Command Priority Disabled By Default

2016-10-19T18:34:36Z

Add a sysfs entry to turn on priority information being passed to a ATA device. By default this feature is turned off. This patch depends on ata: Enabling ATA Command Priorities tj: Renamed ncq_prio_on to ncq_prio_enable and removed trivial ata_ncq_prio_on() and open-coded the test.

ata: Enabling ATA Command Priorities

2016-10-19T18:34:36Z

This patch checks to see if an ATA device supports NCQ command priorities. If so and the user has specified an iocontext that indicates IO_PRIO_CLASS_RT then we build a tf with a high priority command. This is done to improve the tail latency of commands that are high priority by passing priority to the device. tj: Removed trivial ata_ncq_prio_enabled() and open-coded the test.

libata: remove

asm-generic is only intended for architecture defaults, and we can simply kill it off by moving the two defintions directly to . Signed-off-by: Christoph Hellwig Signed-off-by: Tejun Heo

ata: define ATA_PROT_* in terms of ATA_PROT_FLAG_*

2016-07-19T00:55:38Z

This avoid the need to always translate between the two in ata_prot_flags and generally cleans up the taskfile protocol usage. Signed-off-by: Christoph Hellwig Signed-off-by: Tejun Heo

libata: remove ATA_PROT_FLAG_DATA

2016-07-19T00:55:38Z

Instead we can simply check for PIO or DMA in ata_is_data. Signed-off-by: Christoph Hellwig Signed-off-by: Tejun Heo

libata: remove ata_is_nodata

2016-07-19T00:55:37Z

The only caller can just check for !ata_is_data instead. Signed-off-by: Christoph Hellwig Signed-off-by: Tejun Heo

ata: Handle ATA NCQ NO-DATA commands correctly

2016-07-15T12:08:13Z

Add a new taskfile protocol ATA_PROT_NCQ_NODATA to handle ATA NCQ NO-DATA commands correctly. And fixup ata_scsi_zbc_out_xlat() to use it. Signed-off-by: Hannes Reinecke Signed-off-by: Christoph Hellwig Signed-off-by: Tejun Heo

libata: return boolean values from ata_is_*

2016-07-14T14:44:51Z

This way we don't have to worry about the exact bit postition of the test to leak out and any crazy propagation effects in the callers. Suggested-by: Tejun Heo Signed-off-by: Christoph Hellwig Signed-off-by: Tejun Heo

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: 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
