[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.

[RFC] Explicit synchronization for Nouveau
Hi guys,
I'd like to start a new thread about explicit fence synchronization. This time
with a Nouveau twist. :-)
First, let me define what I understand by implicit/explicit sync:
Implicit synchronization
* Fences are attached to buffers
* Kernel manages fences automatically based on buffer read/write access
Explicit synchronization
* Fences are passed around independently
* Kernel takes
