[PATCH 0/3] drm/nouveau: Add support for fence FDs
From: Thierry Reding <treding at nvidia.com>
This small series of patches implements support for waiting on and
emitting fence FDs on kickoff. This enables explicit fencing and can be
used for example to synchronize buffer accesses between the display
engine and the GPU on Tegra.
The first patch lays the groundwork by splitting up nouveau_fence_sync()
to allow reuse. Patch 2 is where the

Even nicer would be to add the fence using
drm_atomic_set_fence_for_plane() in the prepare_fb hook. Assuming this
isn't necessary for correctness (but then I kinda have questions...
