Some things you should consider adding to this:
  - multi-plane support for multi-buffer formats (multiple fds,
multiple pitches, per-plane offset parameter)
  - an out parameter for format, using the DRM FourCC format codes
  - out parameters for a DRM modifier per-plane, to account for tiling
etc (and no longer calling anv_gem_set_tiling)
