Do you have some numbers comparable to
https://bugs.freedesktop.org/show_bug.cgi?id=31588 ?
I'm interested to know if, first, we are able to reproduce those numbers
and, secondly, if we've started to narrow the 3W gap for enabling a pipe
between the Windows driver and ourselves.

The patches themselves look good. A minor bit of code duplication that we
could possibly eliminate in the first...
