Hi,

I had to implement IGT test case and xf86-video-intel support for this
new format(in order to check that it works with gstreamer as we have
userspace requirement for this change), so currently I guess all the
requirements are met. I might need to do some
minor changes in those patches though, once I get some feedback.
