    Performance seems to be much worse with r7xx class hardware:

    The movie playback tests aren't running on my setup for some reason, so I can't compare if Xv playback is any different between KMS and UMS; but I somehow doubt that it's any different though, at least not in a noticeable way.

      The point was not to make Xv be faster with KMS than UMS, but to rather improve the current KMS situation. UMS is still the only practical choice right now.

        The patch says the reason it is needed is because uploading the screen into video memory isn't accelerated yet. It sounds like there's a lot of stuff that still needs to be done before KMS can be considered "done".
