ata: pmp: add quirk for Marvell 4140 SATA PMP

2015-08-10T19:21:05Z

commit 945b47441d83d2392ac9f984e0267ad521f24268 upstream. 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.

libata: force disable trim for SuperSSpeed S238

2015-08-03T16:29:56Z

commit cda57b1b05cf7b8b99ab4b732bea0b05b6c015cc upstream. This device loses blocks, often the partition table area, on trim. Disable TRIM. http://pcengines.ch/msata16a.htm Signed-off-by: Arne Fitzenreiter Signed-off-by: Tejun Heo Signed-off-by: Greg Kroah-Hartman

libata: add ATA_HORKAGE_NOTRIM

2015-08-03T16:29:56Z

commit 71d126fd28de2d4d9b7b2088dbccd7ca62fad6e0 upstream. Some devices lose data on TRIM whether queued or not. This patch adds a horkage to disable TRIM. tj: Collapsed unnecessary if() nesting. Signed-off-by: Arne Fitzenreiter Signed-off-by: Tejun Heo Signed-off-by: Greg Kroah-Hartman

libata: increase the timeout when setting transfer mode

2015-08-03T16:29:54Z

commit d531be2ca2f27cca5f041b6a140504999144a617 upstream. 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: Ignore spurious PHY event on LPM policy change

2015-06-06T15:19:36Z

commit 09c5b4803a80a5451d950d6a539d2eb311dc0fb1 upstream. When the LPM policy is set to ATA_LPM_MAX_POWER, the device might generate a spurious PHY event that cuases errors on the link. Ignore this event if it occured within 10s after the policy change. The timeout was chosen observing that on a Dell XPS13 9333 these spurious events can occur up to roughly 6s after the policy change.

libata: prevent HSM state change race between ISR and PIO

2015-01-30T01:40:48Z

commit ce7514526742c0898b837d4395f515b79dfb5a12 upstream. It is possible for ata_sff_flush_pio_task() to set ap->hsm_task_state to HSM_ST_IDLE in between the time __ata_sff_port_intr() checks for HSM_ST_IDLE and before it calls ata_sff_hsm_move() causing ata_sff_hsm_move() to BUG(). This problem is hard to reproduce making this patch hard to verify, but this fix will prevent the race. I have not been able to reproduce the problem, but here is a crash dump from a 2.6.32 kernel. On examining the ata port's state, its hsm_task_state field has a value of HSM_ST_IDLE: crash> struct ata_port.hsm_task_state ffff881c1121c000 hsm_task_state = 0 Normally, this should not be possible as ata_sff_hsm_move() was called from ata_sff_host_intr(), which checks hsm_task_state and won't call ata_sff_hsm_move() if it has a HSM_ST_IDLE value.
