nv vpe video decoder
Hello,
I have my work on the nv vpe video decoder in a functional
state. In case you didn't know this decoder accelerates mpeg2
video at the idct/mc level. I have verified that it works on
nv40 hardware. I believe it works on nv30 hardware (and
maybe some earlier hardware), but I cannot verify since I have
none.
I will reply with patches against the kernel, drm, ddx
and mesa for
