libata: make gtf_filter per-dev

2009-10-06T04:26:27+00:00

Add ->gtf_filter to ata_device and set it to ata_acpi_gtf_filter when
initializing ata_link.  This is to allow quirks which apply different
gtf filters.

libata: implement more acpi filtering options

2009-10-06T04:26:26+00:00

Currently libata-acpi can only filter DIPM among SATA feature enables
via _GTF.  This patch adds the capability to filter out FPDMA non-zero
offset, in-order guarantee and auto-activation.

libata: cosmetic updates

Reformat them in preparation.

libata: remove spindown skipping and warning

2009-09-01T23:47:20+00:00

This was a hack to give userland shutdown tools time to drop manual
spindown.  All popular distros updated quite some time ago and the due
is well passed.  Drop it.

[libata] add DMA setup FIS auto-activate feature

2009-09-01T23:47:19+00:00

Hopefully results in fewer on-the-wire FIS's and no breakage.  We'll see!

libata: accept late unlocking of HPA

2009-07-29T01:07:09+00:00

On certain configurations, HPA isn't or can't be unlocked during
probing but it somehow ends up unlocked afterwards.  In the following
thread, the problem can be reliably reproduced after resuming from
STR.  The BIOS turns on HPA during boot but forgets to do it during
resume.

  http://thread.gmane.org/gmane.linux.kernel/858310

This patch updates libata revalidation such that it considers native
n_sectors.  If the device size has increased to match native
n_sectors, it's assumed that HPA has been unlocked involuntarily and
the device is recognized as the same one.  This should be fairly safe
while nicely working around the problem.

libata: implement and use HORKAGE_NOSETXFER, take#2

2009-07-15T02:41:46+00:00

PIONEER DVD-RW DVRTD08 times out SETXFER if no media is present.  The
device is SATA and simply skipping SETXFER works around the problem.
Implement ATA_HORKAGE_NOSETXFER and apply it to the device.

Reported by Moritz Rigler in the following thread.

  http://thread.gmane.org/gmane.linux.ide/36790

and by Lars in bko#9540.

Updated to whine and ignore NOSETXFER if PATA component is detected as
suggested by Alan Cox.

ata: Report 16/32bit PIO as best we can

2009-04-16T19:28:23+00:00

The legacy old IDE ioctl API for this is a bit primitive so we try
and map stuff sensibly onto it.

- Set PIO over DMA devices to report 32bit
- Add ability to change the PIO32 settings if the controller permits it
- Add that functionality into the sff drivers
- Add that functionality into the VLB legacy driver
- Turn on the 32bit PIO on the ninja32 and add support there

[libata] Improve timeout handling

2009-03-25T02:52:39+00:00

On a timeout call a device specific handler early in the recovery so that
we can complete and process successful commands which timed out due to IRQ
loss or the like rather more elegantly.

[Revised to exclude the timeout handling on a few devices that inherit from
 SFF but are not SFF enough to use the default timeout handler]
