Subject: [PATCH v4 0/3] AHCI: Add generic MSI-X interrupt support to SATA PCI driver
From: Robert Richter <rrichter@...ium.com>
This patch set adds generic support for MSI-X interrupts to the SATA
PCI driver.
The first 2 patches rework the code, one splits msi and intx code into
separate functions, the other changes interrupt initialization to
store the irq number in the ahci data structure (struct
ahci_host_priv). Both changes are needed to implement MSI-X support in
the last 3rd patch.
v4:
* removed implementation of ahci_init_intx()
* improved patch descriptions
* rebased onto libata/for-4.2
v3:
* store irq number in struct ahci_host_priv
* change initialization order from msix-msi-intx to msi-msix-intx
* improve comments in ahci_init_msix()
* improve error message in ahci_init_msix()
* do not enable MSI-X if MSI is actively disabled for the device
v2:
* determine irq vector from pci_dev->msi_list
Robert Richter (3):
ahci: Move interrupt enablement code to a separate function
ahci: Store irq number in struct ahci_host_priv
AHCI: Add generic MSI-X interrupt support to SATA PCI driver
