I'm running a drm-next kernel with DDX/drm/mesa from git on my r600-based laptop. KMS works well, it gives me nice shineh effects in KDE4 and I'm very happy with it.
I have noticed though that since moving to the 3D-accelerated versions that playing videos in a window takes way more CPU than it used to when I was just on the released versions of all the driver code. It happens with both gl and xv backends to mplayer, and only when in a window not fullscreen.
Is this due to things that are still being worked on in the driver, interrupts springing to mind here, or is it just a consequence of the extra work involved in doing all the fancy compositing effects? The extra usage is coming from X, so I'm hoping it is a driver-incompleteness issue.
