[Qemu-devel] [RfC PATCH 00/15] virtio-gpu:

  Hi,

After a loooong break, here is the next version of virtio-gpu patches.
It is the first batch, with the 2d bits, virgl (3d/opengl) support will
follow later on.

The dust of the virtio-1.0 merge has mostly settled, even though not
all virtio-1.0 bits are upstream yet (main reason why this is RfC).  My
plan is to get virtio-gpu merged upstream as soon as all dependencies
are in.

This series applies on top of mst's virtio-1.0 branch.

Patches 1-4 are virtio-pci patches which have been posted separately
already, included here because the virtio-gpu patches depend on them.

Patches 5-14 are virtio-gpu and virtio-vga patches.  Patches 8+10 with
the virtio-1.0 changes depend on patches 1-4.  I've kept them separate
for now, to simplify review and also to make adaptions easier in case
patches 1-4 are changed during review.  Patch series is not fully
bisectable because of this.  For the non-RfC patch series they will of
course be squashed in.

Patch 15 is a dirty hack to simplify testing with libvirt, this will
be dropped for the merge, we'll need proper libvirt support instead.

If you wanna play with this, here are host + guest git trees for your
convinience:
