[PATCH v5 09/12] drm/virtio: rework virtio_gpu_object_create fencing
Use gem reservation helpers and direct reservation_object_* calls
instead of ttm.
v5: fix fencing (Chia-I Wu).
v3: Due to using the gem reservation object it is initialized and ready
for use before calling ttm_bo_init, so we can also drop the tricky fence
logic which checks whenever the command is in flight still. We can
simply fence our object before submitting the virtio command and be done

[PATCH v7 09/18] drm/virtio: rework virtio_gpu_object_create fencing
Rework fencing workflow. Stop using ttm helpers, use the
virtio_gpu_array_* helpers instead.
Due to using the gem reservation object it is initialized and ready for
use before calling ttm_bo_init. So we can simply use the standard
fencing workflow and drop the tricky logic which checks whenever the
command is in flight still.
v6: rewrite most of the patch.

[PATCH v3 09/12] drm/virtio: rework virtio_gpu_object_create fencing

[PATCH v5 08/12] drm/virtio: rework virtio_gpu_execbuffer_ioctl fencing
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.

[PATCH v6 08/18] drm/virtio: rework virtio_gpu_execbuffer_ioctl fencing
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

[PATCH v3 5/5] drm/virtio: rework resource creation workflow.
This patch moves the virtio_gpu_cmd_create_resource() call (which
notifies the host about the new resource created) into the
virtio_gpu_object_create() function. That way we can call
virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host
already knows about the object when ttm initializes the object and calls
our driver callbacks.
Specifically the object is already created when the
