Merge branch 'for-4.2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2015-07-24T23:54:59+00:00

Pull libata fixes from Tejun Heo:
 "A couple important fixes.

   - A block layer change which removed restriction on max transfer size
     led to silent data corruption on some devices.  A new quirk is
     added to restore the old size limit for the reported device.  If it
     gets reported on more devices, we might have to consider restoring
     the restriction for ATA devices by default.

   - There finally is a SSD which is confirmed to cause data corruption
     on TRIM regardless of which flavor is used.  A new quirk is added
     and the device is blacklisted

   - Other device-specific workarounds"

libata: Do not blacklist M510DC

2015-07-16T16:15:45+00:00

A new Micron drive was just announced, once again recycling the first
part of the model string. Add an underscore to the M510/M550 pattern to
avoid picking up the new DC drive.

libata: increase the timeout when setting transfer mode

2015-07-15T15:56:40+00:00

I have a ST4000DM000 disk. If Linux is booted while the disk is spun down,
the command that sets transfer mode causes the disk to spin up. The
spin-up takes longer than the default 5s timeout, so the command fails and
timeout is reported.

Fix this by increasing the timeout to 15s, which is enough for the disk to
spin up.

libata: add ATA_HORKAGE_MAX_SEC_1024 to revert back to previous max_sectors limit

2015-07-15T15:47:24+00:00

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: force disable trim for SuperSSpeed S238

ata: pmp: add quirk for Marvell 4140 SATA PMP

2015-07-14T21:46:38+00:00

This commit adds the necessary quirk to make the Marvell 4140 SATA PMP
work properly. This PMP doesn't like SRST on port number 4 (the host
port) so this commit marks this port as not supporting SRST.

ata: ahci_platform: Add ACPI _CLS matching

2015-07-06T23:55:21+00:00

This patch adds ACPI supports for AHCI platform driver, which uses _CLS
method to match the device.

The following is an example of ASL structure in DSDT for a SATA controller,
which contains _CLS package to be matched by the ahci_platform driver:

  Device (AHC0) // AHCI Controller
  {
    Name(_HID, "AMDI0600")
    Name (_CCA, 1)
    Name (_CLS, Package (3)
    {
      0x01, // Base Class: Mass Storage
      0x06, // Sub-Class: serial ATA
      0x01, // Interface: AHCI
    })
    Name (_CRS, ResourceTemplate ()
    {
      Memory32Fixed (ReadWrite, 0xE0300000, 0x00010000)
      Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive,,,) { 387 }
    })
  }

Also, since ATA driver should not require PCI support for ATA_ACPI,
this patch removes dependency in the driver/ata/Kconfig.
