[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

[PATCH 0/6] drm/nouveau: Support sync FDs and sync objects
From: Thierry Reding <treding at nvidia.com>
Hi,
This series implements a new IOCTL to submit push buffers that can
optionally return a sync FD or sync object to userspace. This is useful
in cases where userspace wants to synchronize operations between the GPU
and another driver (such as KMS for display). Among other things this
allows extensions such as eglDupNativeFenceFDANDROID to be
