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.

sata_fsl: fix error handling of irq_of_parse_and_map

2014-12-02T17:52:17Z

irq_of_parse_and_map() returns 0 on error (the result is unsigned int), so testing for negative result never works. Signed-off-by: Dmitry Torokhov Signed-off-by: Tejun Heo Cc: stable@vger.kernel.org

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.

Revert "AHCI: Optimize single IRQ interrupt processing"

2014-10-27T16:02:05Z

This reverts commit 18dcf433f3ded61eb140a55e7048ec2fef79e723. IRQF_ONESHOT was missing from the conversion causing screaming interrupts problems on some setups and LKP detected measureable drop in IO performance. It looks like we'll first need to drop the threaded IRQ handling first before splitting locking.
