[PATCH v1 0/3] drm/virtio: Add a default synchronization mechanism for blobs

[Vivek Kasireddy]

This 3 patch series is the counterpart for this other series:
https://lists.nongnu.org/archive/html/qemu-devel/2021-06/msg02906.html

It makes it possible for the Guest to wait until the Host has 
completely consumed its FB before reusing it again thereby ensuring
that both the parties don't access it at the same time.
