[Qemu-devel] [PATCH 00/11] qemu: MSI-X support

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

Here is the port of MSI-X support patches to upstream qemu.
Anthony, you said you are willing to borrow a few cycles to help MSI-X
go in through QEMU - could you 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 is on top of 'PATCHv2 make default_write_config use mask table'
that I posted previously. I have included that patch here
for completeness.
