Revert "libata: Implement NCQ autosense"

2015-08-03T16:01:54Z

This reverts commit 42b966fbf35da9c87f08d98f9b8978edf9e717cf. As implemented, ACS-4 sense reporting for ATA devices bypasses error diagnosis and handling in libata degrading EH behavior significantly. Revert the related changes for now.

This reverts commit fe7173c206de63fc28475ee6ae42ff95c05692de. As implemented, ACS-4 sense reporting for ATA devices bypasses error diagnosis and handling in libata degrading EH behavior significantly. Revert the related changes for now. ATA_ID_COMMAND_SET_3/4 constants are not reverted as they're used by later changes. Signed-off-by: Tejun Heo Cc: Hannes Reinecke Cc: stable@vger.kernel.org #v4.1+

libata: add ATA_HORKAGE_MAX_SEC_1024 to revert back to previous max_sectors limit

2015-07-15T15:47:24Z

Since no longer limiting max_sectors to BLK_DEF_MAX_SECTORS (commit 34b48db66e08), data corruption may occur on ST380013AS drive configured on 82801JI (ICH10 Family) SATA controller. This patch will allow the driver to limit max_sectors as before # cat /sys/block/sdb/queue/max_sectors_kb 512 I was able to double the max_sectors_kb value up to 16384 on linux-4.2.0-rc2 before seeing corruption, but seems safer to use previous limit. Without this patch max_sectors_kb will be 32767. tj: Minor comment update.

libata: READ LOG DMA EXT support can be in either page 119 or 120

2015-05-05T13:30:19Z

Support for the READ/WRITE LOG DMA EXT commands can be signaled either in page 119 or page 120. We should check both pages. Signed-off-by: Martin K. Petersen Reviewed-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: Implement support for sense data reporting

ACS-4 defines a sense data reporting feature set. This patch implements support for it. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: Implement NCQ autosense

2015-03-27T15:59:22Z

Some newer devices support NCQ autosense (cf ACS-4), so we should be using it to retrieve the sense code and speed up recovery. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo

libata: use READ_LOG_DMA_EXT

2015-03-27T15:59:21Z

If READ_LOG_DMA_EXT is supported we should try to use it for reading the log pages. Signed-off-by: Hannes Reinecke Signed-off-by: Tejun Heo
