[RFC PATCH 0/8] *** Per context fencing ***

[Gurchetan Singh]

We don't want fences from different 3D contexts/processes (GL, VK) to
be on the same timeline. Sending this out as a RFC to solicit feedback
on the general approach.

Gurchetan Singh (8):
  drm/virtio: use fence_id when processing fences
  drm/virtio: allocate a fence context for every 3D context
  drm/virtio: plumb virtio_gpu_fpriv to virtio_gpu_fence_alloc
  drm/virtio: rename sync_seq and last_seq
  drm/virtio: track fence_id in virtio_gpu_fence
  virtio/drm: rework virtio_fence_signaled
  drm/virtio: check context when signaling
  drm/virtio: enable per context fencing
