sata_svw: check DMA start bit before reset

2012-12-03T20:59:15+00:00

commit b03e66a6be91f8389fcd902ab6c1563db1c9c06b upstream.

If kdump is triggered with pending IO, controller may not respond causing
kdump to fail.

http://marc.info/?l=linux-ide&m=133032255424658&w=2

During error recovery ata_do_dev_read_id never completes due hang
in mmio_insw.

ata_do_dev_read_id
 ata_sff_data_xfer
  ioread16_rep
   mmio_insw

if DMA start bit is cleared before reset, PIO command is successful
and kdump succeeds.

libata: Prevent interface errors with Seagate FreeAgent GoFlex

2012-10-02T16:47:41+00:00

commit c531077f40abc9f2129c4c83a30b3f8d6ce1c0e7 upstream.

When using my Seagate FreeAgent GoFlex eSATAp external disk enclosure,
interface errors are always seen until 1.5Gbps is negotiated [1]. This
occurs using any disk in the enclosure, and when the disk is connected
directly with a generic passive eSATAp cable, we see stable 3Gbps
operation as expected.

Blacklist 3Gbps mode to avoid dataloss and the ~30s delay bus reset
and renegotiation incurs.

ahci: Add alternate identifier for the 88SE9172

2012-10-02T16:47:25+00:00

commit 17c60c6b763cb5b83b0185e7d38d01d18e55a05a upstream.

This can also appear as 0x9192. Reported in bugzilla and confirmed with the
board documentation for these boards.

ahci: Detect Marvell 88SE9172 SATA controller

2012-06-01T07:12:55+00:00

commit 642d89252201c4155fc3946bf9cdea409e5d263e upstream.

The Marvell 88SE9172 SATA controller (PCI ID 1b4b 917a) already worked
once it was detected, but was missing an ahci_pci_tbl entry.

Boot tested on a Gigabyte Z68X-UD3H-B3 motherboard.

libata: skip old error history when counting probe trials

2012-05-07T15:56:39+00:00

commit 6868225e3e92399068be9a5f1635752d91012ad5 upstream.

Commit d902747("[libata] Add ATA transport class") introduced
ATA_EFLAG_OLD_ER to mark entries in the error ring as cleared.

But ata_count_probe_trials_cb() didn't check this flag and it still
counts the old error history. So wrong probe trials count is returned
and it causes problem, for example, SATA link speed is slowed down from
3.0Gbps to 1.5Gbps.

Fix it by checking ATA_EFLAG_OLD_ER in ata_count_probe_trials_cb().

pata_legacy: correctly mask recovery field for HT6560B

2012-04-02T16:27:13+00:00

commit 9716387311c790de381214c03e7f1b72b91a8189 upstream.

According to the HT6560H datasheet, the recovery timing field is 4-bit wide,
with a value of 0 meaning 16 cycles. Correct obvious thinko in the recovery
field mask.

ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge chipsets(v2)

2011-11-11T17:35:50+00:00

commit 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d upstream.

This quirk patch fixes one kind of bug inside some Intel Sandybridge
chipsets, see reports from

       https://bugzilla.kernel.org/show_bug.cgi?id=40592.

Many guys also have reported the problem before:

	https://bugs.launchpad.net/bugs/737388
	https://bugs.launchpad.net/bugs/794642
	https://bugs.launchpad.net/bugs/782389
	......

With help from Tejun, the problem is found to be caused by 32bit PIO
mode, so introduce the quirk patch to disable 32bit PIO on SATA piix
for some Sandybridge CPT chipsets.

Seth also tested the patch on all five affected chipsets
(pci device ID: 0x1c00, 0x1c01, 0x1d00, 0x1e00, 0x1e01), and found
the patch does fix the problem.

ahci: Enable SB600 64bit DMA on Asus M3A

2011-10-16T21:14:54+00:00

commit 3c4aa91f21f65b7b40bdfb015eacbcb8453ccae2 upstream.

Like e65cc194f7628ecaa02462f22f42fb09b50dcd49 this patch enables 64bit DMA
for the AHCI SATA controller of a board that has the SB600 southbridge. In
this case though we're enabling 64bit DMA for the Asus M3A motherboard. It
is a new enough board that all of the BIOS releases since the initial
release (0301 from 2007-10-22) work correctly with 64bit DMA enabled.

pata_via: disable ATAPI DMA on AVERATEC 3200

2011-10-03T18:39:57+00:00

commit 6d0e194d2eefcaab6dbdca1f639748660144acb5 upstream.

On AVERATEC 3200, pata_via causes memory corruption with ATAPI DMA,
which often leads to random kernel oops.  The cause of the problem is
not well understood yet and only small subset of machines using the
controller seem affected.  Blacklist ATAPI DMA on the machine.
