ahci: Add Device ID for HighPoint RocketRaid 642L

2014-06-16T20:45:46Z

commit d251836508fb26cd1a22b41381739835ee23728d upstream. This device normally comes with a proprietary driver, using a web GUI to configure RAID: http://www.highpoint-tech.com/USA_new/series_rr600-download.htm But thankfully it also works out of the box with the AHCI driver, being just a Marvell 88SE9235. Devices 640L, 644L, 644LS should also be supported but not tested here. Signed-off-by: Jérôme Carretero Signed-off-by: Tejun Heo Signed-off-by: Greg Kroah-Hartman

pata_at91: fix ata_host_activate() failure handling

2014-06-07T23:02:00Z

commit 27aa64b9d1bd0d23fd692c91763a48309b694311 upstream. Add missing clk_put() call to ata_host_activate() failure path. Sergei says, "Hm, I have once fixed that (see that *if* (!ret)) but looks like a later commit 477c87e90853d136b188c50c0e4a93d01cad872e (ARM: at91/pata: use gpio_is_valid to check the gpio) broke it again. :-( Would be good if the changelog did mention that..."

libata/ahci: accommodate tag ordered controllers

2014-05-13T12:11:31Z

commit 8a4aeec8d2d6a3edeffbdfae451cdf05cbf0fefd upstream. The AHCI spec allows implementations to issue commands in tag order rather than FIFO order: 5.3.2.12 P:SelectCmd HBA sets pSlotLoc = (pSlotLoc + 1) mod (CAP.NCS + 1) or HBA selects the command to issue that has had the PxCI bit set to '1' longer than any other command pending to be issued. The result is that commands posted sequentially (time-wise) may play out of sequence when issued by hardware. This behavior has likely been hidden by drives that arrange for commands to complete in issue order. However, it appears recent drives (two from different vendors that we have found so far) inflict out-of-order completions as a matter of course. So, we need to take care to maintain ordered submission, otherwise we risk triggering a drive to fall out of sequential-io automation and back to random-io processing, which incurs large latency and degrades throughput. This issue was found in simple benchmarks where QD=2 seq-write performance was 30-50% *greater* than QD=32 seq-write performance. Tagging for -stable and making the change globally since it has a low risk-to-reward ratio. Also, word is that recent versions of an unnamed OS also does it this way now. So, drives in the field are already experienced with this tag ordering scheme.

libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8 (2BA30001)

2014-03-24T04:37:06Z

commit b28a613e9138e4b3a64649bd60b13436f4b4b49b upstream. Via commit 87809942d3fa "libata: add ATA_HORKAGE_BROKEN_FPDMA_AA quirk for Seagate Momentus SpinPoint M8" we added a quirk for disks named "ST1000LM024 HN-M101MBB" with firmware revision "2AR10001". As reported on https://bugzilla.redhat.com/show_bug.cgi?id=1073901, we need to also add firmware revision 2BA30001 as it is broken as well.

sata_sil: apply MOD15WRITE quirk to TOSHIBA MK2561GSYN

2014-03-11T23:10:00Z

commit 9f9c47f00ce99329b1a82e2ac4f70f0fe3db549c upstream. It's a bit odd to see a newer device showing mod15write; however, the reported behavior is highly consistent and other factors which could contribute seem to have been verified well enough. Also, both sata_sil itself and the drive are fairly outdated at this point making the risk of this change fairly low. It is possible, probably likely, that other drive models in the same family have the same problem; however, for now, let's just add the specific model which was tested.
