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

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
