Drop the virtio_gpu_{disable,enable}_notify(). Add a new virtio_gpu_notify() call instead, which must be called whenever the driver wants make sure the host is notified needed. Drop notification from command submission. Add virtio_gpu_notify() calls everywhere instead. This results in more batching because we now notify only once for a series of commands. We already had that for page flips,

No need to do the reservation dance, we can just wait on the fence directly.

From: Gustavo Padovan <gustavo.padovan at collabora.co.uk> Refactor fence creation to remove the potential allocation failure from the cmd_submit and atomic_commit paths. Now the fence should be allocated first and just after we should proceed with the rest of the execution.

Move virtio_gpu_notify() to higher-level functions for virtio_gpu_cmd_resource_flush(), virtio_gpu_cmd_set_scanout() and virtio_gpu_cmd_transfer_to_host_{2d,3d}(). virtio_gpu_primary_plane_update() will notify only once for a series of commands (restores plane update command batching).
