libata: Implement NCQ autosense

2015-03-27T15:59:22+00:00

Some newer devices support NCQ autosense (cf ACS-4), so we should
be using it to retrieve the sense code and speed up recovery.

libata: use READ_LOG_DMA_EXT

If READ_LOG_DMA_EXT is supported we should try to use it for
reading the log pages.

libata: move 'struct ata_taskfile' and friends from ata.h to libata.h

2013-07-16T11:46:56+00:00

Move 'struct ata_taskfile', ata_prot_flags() and their friends from
 to . They were misplaced from the beginning,  as
 should cover ATA/ATAPI and related standards only -- to which the
aforementioned structure and function have only remote relation.

I would have moved 'enum ata_tf_protocols' closely related to 'struct
ata_taskfile' but it unfortunately gets used by 'drivers/ide/ide-ioctls.c'...

libata: Use integer return value for atapi_command_packet_set

2013-04-03T23:33:40+00:00

The function returns type of ATAPI drives so it should return integer value.
The commit 4dce8ba94c7 (libata: Use 'bool' return value for ata_id_XXX) since
v2.6.39 changed the type of return value from int to bool, the change would
cause all of the ATAPI class drives to be treated as TYPE_TAPE and the
max_sectors of the drives to be set to 65535 because of the commit
f8d8e5799b7(libata: increase 128 KB / cmd limit for ATAPI tape drives), for the
function would return true for all ATAPI class drives and the TYPE_TAPE is
defined as 0x01.

[libata] replace sata_settings with devslp_timing

2013-01-14T18:29:15+00:00

NCQ capability was used to check availability of SATA Settings page
from Identify Device Data Log, which contains DevSlp timing variables.
It does not work on some HDDs and leads to error messages.

IDENTIFY word 78 bit 5(Hardware Feature Control) can't work either
because it is only the sufficient condition of Identify Device data
log, not the necessary condition.

This patch replaced ata_device->sata_settings with ->devslp_timing
to only save DevSlp timing variables(8 bytes), instead of the whole
SATA Settings page(512 bytes).
