I've provided a patch for the modesetting driver and the preliminary
bits are merged, leaving only a fairly straightforward addition of the
new ioctls to that code. I'm not sure how to make more progress there at
this point; that code would need testing, and it requires a hand-patched
kernel to test.
I also posted IGT tests for the new functionality, again, getting those
reviewed and tested depends on someone willing to build a patched
kernel. Dave Airlie has started trying to get that done.

Michel Dänzer says that the timestamp provided is computed to be
first_pixel_out for all hardware. Given that, I suggest we specify that
in the documentation and remove this bit from the API.
Seem reasonable?
