[PFC PATCH 0/3] drm/virtio: synchronous guest framebuffer update

[Dongwon Kim]

"Resubmission"

This series is for fixing issues regarding scanout synchronization with
host (e.g. QEMU/KVM) that uses virtio-gpu. This was submitted a while ago
but didn't get enough feedback/reviews so I am trying it again. This is a
rebased version. And the previous version is at
https://lists.freedesktop.org/archives/dri-devel/2022-September/373782.html

And very first version that has some feedbacks can be found here:
https://www.spinics.net/lists/dri-devel/msg349641.html
