Hi Sean,

Yes these are patches to extend existing vaapi backend provided by mesa.
Maybe at some point the efforts should be joined with
http://cgit.freedesktop.org/vaapi/intel-driver/. I mean, it would be great
if vaapi-intel-driver maintainers could start improving mesa-vaapi instead.
To gradually move from this specific backend to the generic one in mesa. It
is generic in a sense it does not use libdrm directly but a common wrapper
in between. So the same vaapi backend in mesa is working for all gallium
drivers.

If this was your question behind :)

Cheers
Julien
