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

As it turns out, with the proprietary firmware, the VP3 and VP4 interfaces are identical. Furthermore, this is all already implemented for nvc0. So these patches (a) move the easily sharable bits of the nvc0 implementation into the nouveau directory, and then (b) implement the other parts in nv50. The non-shared parts are still largely copies, but there are some differences, not the least of which
