Prevent interface errors with Seagate FreeAgent GoFlex

2012-10-10T02:31:10+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: Detect Marvell 88SE9172 SATA controller

2012-05-30T23:43:48+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

2012-05-11T12:14:52+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

2012-04-02T16:52:49+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.

[libata] ahci_platform: fix DT probing

2011-11-17T07:10:49+00:00

The change in commit 904c04feaf13ed "ahci_platform: Add the board_ids..."
doesn't work for the DT probing case as platform_get_device_id returns
NULL. Pick the default ahci_port_info in this case.

pata_of_platform: Don't use NO_IRQ

2011-11-10T20:57:59+00:00

Drivers should not use NO_IRQ; moreover, some architectures don't
have it nowadays. '0' is the 'no irq' case.
