      libata: Fix ATA request sense · 2dae9955
      由 Damien Le Moal 提交于 
      For an ATA device supporting the sense data reporting feature set, a
failed command will trigger the execution of ata_eh_request_sense if
the result task file of the failed command has the ATA_SENSE bit set
(sense data available bit). ata_eh_request_sense executes the REQUEST
SENSE DATA EXT command to retrieve the sense data of the failed
command. On success of REQUEST SENSE DATA EXT, the ATA_SENSE bit will
NOT be set (the command succeeded) but ata_eh_request_sense
nevertheless tests the availability of sense data by testing that bit
presence in the result tf of the REQUEST SENSE DATA EXT command.  This
leads us to falsely assume that request sense data failed and to the
warning message:

atax.xx: request sense failed stat 50 emask 0

Upon success of REQUEST SENSE DATA EXT, set the ATA_SENSE bit in the
result task file command so that sense data can be returned by
ata_eh_request_sense.

      libata: apply MAX_SEC_1024 to all CX1-JB*-HP devices · e0edc8c5
      由 Tejun Heo 提交于 
      Marko reports that CX1-JB512-HP shows the same timeout issues as
CX1-JB256-HP.  Let's apply MAX_SEC_128 to all devices in the series.

      ata: avoid probing NCQ Prio Support if not explicitly requested · 9f56eca3
      由 Adam Manzanares 提交于 
      Previously, when the ata device was being initialized we were
probing for NCQ prio support by checking the identify information
and also checking the log page that holds information about ncq prio
support.

This caused an error on an Intel HBA so the code is now updated to
only probe for NCQ prio support when the sysfs variable controlling
NCQ prio support is enabled.

tj: Update formatting, switch to spin_[un]lock_irq() and update
    locking a bit, use REVALIDATE instead of RESET, and return -EIO
    instead of -EINVAL on config failure.

      leds: convert IDE trigger to common disk trigger · eb25cb99
      由 Stephan Linz 提交于 
      This patch converts the IDE specific LED trigger to a generic disk
activity LED trigger. The libata core is now a trigger source just
like before the IDE disk driver. It's merely a replacement of the
string ide by disk.

The patch is taken from http://dev.gentoo.org/~josejx/ata.patch and is
widely used by any ibook/powerbook owners with great satisfaction.
Likewise, it is very often used successfully on different ARM platforms.

Unlike the original patch, the existing 'ide-disk' trigger is still
available for backward compatibility. That reduce the amount of patches
in affected device trees out of the mainline kernel. For further
development, the new name 'disk-activity' should be used.

      ata: core: fix irq description on AHCI single irq systems · 7e22c002
      由 Heiner Kallweit 提交于 
      On my machine with single irq AHCI just the PCI id is printed as
description in /proc/interrupts.
I found a related discussion from beginning of this year:
http://www.gossamer-threads.com/lists/linux/kernel/2117335

Seems like 4f37b504 ("libata: Use dev_name() for request_irq() to
distinguish devices") tried to fix displaying a proper interrupt
description for one scenario but broke it for another one.

The mentioned discussion ended in the current situation being
considered as broken but w/o a patch to fix it.

The following patch is based on a proposal in this mail thread.
Now the interrupt is properly described as:
PCI-MSI 512000-edge      ahci[0000:00:1f.2]

By combining both values also the scenario that commit 4f37b504
("libata: Use dev_name() for request_irq() to distinguish devices")
refers to should still be fine. There it should look like this now:
ahci[20100000.ide]

Using managed memory allocation ensures that the irq description
lives at least as long as the interrupt.

      由 Tejun Heo 提交于 
      This reverts commit fe7173c2.

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.
