[PATCH v2 00/20] Various vhost-user-gpu & UI fixes

[marcandre.lureau@redhat.com]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Hi,

Here is a collection of fixes and improvements mostly around vhost-user-gpu. In
combination with spice, they work best with the previously sent fixes ("[PATCH
0/2] Fix (non-vga) QXL async screendump" & "[PATCH v2] spice: delay starting
until display are initialized"). I also use virgl from git, which seems to work
better. You also need mesa with the recent fix !8663 from last week if you test
this.

The last patch is a simple RFC avocado test to have the basics under some
control and avoid simple regressions.

I have further refactoring work pending to separate the DisplayChangeListener
from the GL context. This should allow to run a GL-less qemu with Spice client &
vhost-user-gpu/virgl for example.

v2:
 - styles fixes
 - drop RFC from avocado test
