[PATCH 0/3] drm/tegra: Add support for fence FDs
From: Thierry Reding <treding at nvidia.com>
This set of patches adds support for fences to Tegra DRM and complements
the fence FD support for Nouveau. Technically this isn't necessary for a
fence-based synchronization loop with Nouveau because the KMS core takes
care of all that, but engines behind host1x can use the IOCTL extensions
provided here to emit fence FDs that in turn can be
