The test looks good to me (I haven't checked in details, the bar for igt
is quite a bit lower). It shows two gaps in the igt kms API:

  - Retrieving the primary plane (there's a series from Matt fixing this
    and exposing the primary plane through igt_output_get_plane())
  - Adding a set_property() convenience function
    (ala igt_plane_set_property("rotation", BIT(DRM_ROTATE_180)))
    (no-one is working on that just yet, can de done later)

A small question before pushing this, have you checked that the test
correctly skips when running with a kernel without rotation support?

Thanks,
