[RFC 1/5] drm/virtio: add virtio_gpu_alloc_fence()
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.

[PATCH v2 5/6] drm/virtio: drop fencing in virtio_gpu_resource_create_ioctl

No.
But you pass in a list of objects (drm_virtgpu_execbuffer->bo_handles)
used. They will all get reserved, so you can use DRM_IOCTL_VIRTGPU_WAIT
on any of these objects to wait for completion.
Recently the driver got support for returning a fence fd for the
execbuffer, which you can also use to wait for completion in case your
kernel is new enough.
