Maybe it'd make sense to finish up the various userspace parts first, so that we can test an accelerated DDX on top of the kernel patches before merging the host1x and gr2d patches. I'm not quite sure if I remember correctly, but I think David mentioned something along the lines of requiring a working userspace that can be used to test the DRM interfaces as a prerequisite to getting this kind of code merged.
