libata: support concurrent positioning ranges log

2021-10-27T03:01:48Z

Add support to discover if an ATA device supports the Concurrent Positioning Ranges data log (address 0x47), indicating that the device is capable of seeking to multiple different locations in parallel using multiple actuators serving different LBA ranges. Also add support to translate the concurrent positioning ranges log into its equivalent Concurrent Positioning Ranges VPD page B9h in libata-scsi.c. The format of the Concurrent Positioning Ranges Log is defined in ACS-5 r9. Signed-off-by: Damien Le Moal Reviewed-by: Hannes Reinecke Reviewed-by: Christoph Hellwig Reviewed-by: Martin K.

ata: Replace inclusion of kernel.h by bits.h in the header

2021-05-17T15:10:20Z

ata.h uses BIT() macro, hence bits.h must be included. Otherwise there is no need to have kernel.h included, I do not see any direct users of it in ata.h. Hence replace inclusion of kernel.h.

libata: check for trusted computing in IDENTIFY DEVICE data

2017-08-29T15:33:24Z

ATA-8 and later mirrors the TRUSTED COMPUTING SUPPORTED bit in word 48 of the IDENTIFY DEVICE data. Check this before issuing a READ LOG PAGE command to avoid issues with buggy devices. The only downside is that we can't support Security Send / Receive for a device with an older revision due to the conflicting use of this field in earlier specifications. tj: The reason we need this is because some devices which don't support READ LOG PAGE lock up after getting issued that command.

libata: remove SCT WRITE SAME support

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.
