ahci: avoton port-disable reset-quirk

2015-06-06T15:21:01Z

commit dbfe8ef5599a5370abc441fcdbb382b656563eb4 upstream. Avoton AHCI occasionally sees drive probe timeouts at driver load time. When this happens SCR_STATUS indicates device detected, but no D2H FIS reception. Reset the internal link state machines by bouncing port-enable in the PCS register when this occurs.

ahci: disable MSI on SAMSUNG 0xa800 SSD

2014-12-04T18:18:55Z

Just like 0x1600 which got blacklisted by 66a7cbc303f4 ("ahci: disable MSI instead of NCQ on Samsung pci-e SSDs on macbooks"), 0xa800 chokes on NCQ commands if MSI is enabled. Disable MSI.

ahci: fix AHCI parameters not taken into account

2014-11-04T17:56:25Z

Changes into the AHCI subsystem have introduced a bug by not taking into account the force_port_map and mask_port_map parameters when using the ahci_pci_save_initial_config function. This commit fixes it by setting the internal parameters of the ahci_port_priv structure. Fixes: 725c7b570fda Reported-and-tested-by: Zlatko Calusic Signed-off-by: Antoine Tenart

ahci: disable MSI instead of NCQ on Samsung pci-e SSDs on macbooks

2014-10-27T16:02:11Z

Samsung pci-e SSDs on macbooks failed miserably on NCQ commands, so 67809f85d31e ("ahci: disable NCQ on Samsung pci-e SSDs on macbooks") disabled NCQ on them. It turns out that NCQ is fine as long as MSI is not used, so let's turn off MSI and leave NCQ on.

Merge branch 'for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

2014-10-10T11:23:11Z

Pull libata update from Tejun Heo: "AHCI is getting per-port irq handling and locks for better scalability. The gain is not huge but measureable with multiple high iops devices connected to the same host; however, the value of threaded IRQ handling seems negligible for AHCI and it likely will revert to non-threaded handling soon. Another noteworthy change is George Spelvin's "libata: Un-break ATA blacklist". During 3.17 devel cycle, the libata blacklist glob matching got generalized and rewritten; unfortunately, the patch forgot to swap arguments to match the new match function and ended up breaking blacklist matching completely. It got noticed only a couple days ago so it couldn't make for-3.17-fixes either. :( Other than the above two, nothing too interesting - the usual cleanup churns and device-specific changes" * 'for-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata: (22 commits) pata_serverworks: disable 64-KB DMA transfers on Broadcom OSB4 IDE Controller libata: Un-break ATA blacklist AHCI: Do not acquire ata_host::lock from single IRQ handler AHCI: Optimize single IRQ interrupt processing AHCI: Do not read HOST_IRQ_STAT reg in multi-MSI mode AHCI: Make few function names more descriptive AHCI: Move host activation code into ahci_host_activate() AHCI: Move ahci_host_activate() function to libahci.c AHCI: Pass SCSI host template as arg to ahci_host_activate() ata: pata_imx: Use the SIMPLE_DEV_PM_OPS() macro AHCI: Cleanup checking of multiple MSIs/SLM modes libata-sff: Fix controllers with no ctl port ahci_xgene: Fix the error print invalid resource for APM X-Gene SoC AHCI SATA Host Controller driver. libata: change ata__printk routines to return void ata: qcom: Add device tree bindings information ahci-platform: Bump max number of clocks to 5 ahci: ahci_p5wdh_workaround - constify DMI table libahci_platform: Staticize ahci_platform_able_phys() pata_platform: Remove useless irq_flags field pata_of_platform: Remove "electra-ide" quirk ...

AHCI: Move host activation code into ahci_host_activate()

2014-10-06T15:43:35Z

Currently host activation done by calling either function ahci_host_activate() or ata_host_activate(). Consolidate the code by only calling ahci_host_activate() for all AHCI devices. Signed-off-by: Alexander Gordeev Signed-off-by: Tejun Heo Cc: linux-ide@vger.kernel.org

AHCI: Move ahci_host_activate() function to libahci.c
