Which is small for a drm driver.

Seems vkms only supports prime import, not prime export.

The idea here is: if we run the vm headless, we don't really need to
communicate with VMM, and we even don't need any VMM support
for virtio-gpu. Of course, only 2d works. But it's enough for some
use case. And this looks simpler than vkms.

Hi,
I'd like to get comments on this before I polish it. This is a
simple way to get something similar with vkms but it heavily reuse
the code provided by virtio-gpu. Please feel free to give me any
feedbacks or comments.
Thanks!
