AHCI: Remove obsolete Intel Lewisburg SATA RAID device IDs

2016-03-11T17:31:49Z

These PCI device IDs have been removed from the Intel Lewisburg design specification. They are no longer needed. Signed-off-by: Scott Lawson Signed-off-by: Tejun Heo

ahci: Workaround for ThunderX Errata#22536

2016-02-29T21:16:26Z

Due to Errata in ThunderX, HOST_IRQ_STAT should be cleared before leaving the interrupt handler. The patch attempts to satisfy the need. Changes from V2: - removed newfile - code is now under CONFIG_ARM64 Changes from V1: - Rebased on top of libata/for-4.6 - Moved ThunderX intr handler to new file tj: Minor adjustments to comments.

ahci: Add runtime PM support for the host controller

2016-02-19T15:52:46Z

This patch adds runtime PM support for the AHCI host controller driver so that the host controller is powered down when all SATA ports are runtime suspended. Powering down the AHCI host controller can reduce power consumption and possibly allow the CPU to enter lower power idle states (S0ix) during runtime. Runtime PM is blocked by default and needs to be unblocked from userspace as needed (via power/* sysfs nodes). Signed-off-by: Mika Westerberg Signed-off-by: Tejun Heo

ahci: Convert driver to use modern PM hooks

2016-02-19T15:52:46Z

In order to add support for runtime PM to the ahci driver we first need to convert the driver to use modern non-legacy system suspend hooks. There should be no functional changes. tj: Updated .driver.pm init for older compilers as suggested by Andy and Chrsitoph.

ahci: per-port msix support

2015-11-16T16:29:10Z

Some AHCI controllers support per-port MSI-X vectors. At the same time the Linux AHCI driver needs to support one-off architectures that implement a single MSI-X vector for all ports. The heuristic for enabling AHCI ports becomes, in order of preference: 1/ per-port multi-MSI-X 2/ per-port multi-MSI 3/ single MSI 4/ single MSI-X 5/ legacy INTX This all depends on AHCI implementations with potentially broken MSI-X requesting less vectors than the number of ports. If this assumption is violated we will need to start explicitly white-listing AHCI-MSIX implementations.

ahci: Order SATA device IDs for codename Lewisburg

2015-11-16T16:22:16Z

This change was to preserve the ascending order of device IDs. There was an exception with the first two Lewisburg device IDs to keep all device IDs of the same kind grouped by code name. Signed-off-by: Alexandra Yates signed-off-by: Tejun Heo
