[Qemu-devel] [PATCHv2 00/13] qemu: MSI-X support

["Michael S. Tsirkin" <mst@redhat.com>]

Resending. Incorporated a minor fix pointed out by Isaku Yamahata.

Here is the port of MSI-X support patches to upstream qemu.
Please comment or commit.

This patchset adds generic support for MSI-X, adds implementation in
APIC, and uses MSI-X in virtio-net. At Paul's suggestion, I use stl_phy
to decouple APIC and MSI-X implementation.

This uses the mask table patch that I posted previously, and which is
now included in the series.
