Some minor comments below. I had to fix dri-devel mailing list

Use gem reservation helpers and direct reservation_object_* calls instead of ttm. v5: fix fencing (Chia-I Wu). v3: Also attach the array of gem objects to the virtio command buffer, so we can drop the object references in the completion callback. Needed because ttm fence helpers grab a reference for us, but gem helpers don't. Signed-off-by: Gerd Hoffmann <kraxel at redhat.com>

Rework fencing workflow, starting with virtio_gpu_execbuffer_ioctl. Stop using ttm helpers, use the virtio_gpu_array_* helpers (which work on the reservation objects directly) instead. New workflow: (1) All gem objects needed by a command are added to a virtio_gpu_object_array. (2) All reservation objects will be locked (virtio_gpu_array_lock_resv). (3) virtio_gpu_fence_emit() completes

This is to allow clients running within VMs to be able to communicate with a compositor in the host. Clients will use the communication protocol that the compositor supports, and virtio-gpu will assist with making buffers available in both sides, and copying content as needed. It is expected that a service in the guest will act as a proxy, interacting with virtio-gpu to support unmodified
