[Libva] G45 h264 decoding

[Andreas Gustafsson]

Hello!

I'm hitting a similar problem when trying out the g45-h264 branch.
Running at abysmal speeds and getting kernel errors.

What concerns me is that when I'm checking the Debian kernel source the
drm/i915 BSD ring patch is already applied.

Are you having any ideas?

Thanks,
Andreas
