Dynamic Clocks For Radeon R500+

X

That branch is basically a proof of concept. It only implements sclk, mclk, and pcie lane adjustments statically based on the mode you select in your xorg.conf. There's a lot more involved. There is currently no interface in X to do this dynamically, so I've been looking at implementing it the radeon kms drm. Then userspace utilities like gnome-power-manager can adjust power policy on the fly.

You won't be able to change the power profile live, you will have to restart the server
Thank you for the reply

I'm actually using the latest git revision of xf86-video-radeon. The driver works beautifully. 2D performance are awesome and 3D is improving. Concerning powerplay options I'm unable to set any mode in my xorg config file. It seems thatCode:Option "PowerPlayMode" "1,2 or 3"
Thanks in advance

Option "DynamicClocks" "TRUE"
to the device section of your config.
my powerplay stuff is available here:
however, you can't dynamically change the power state at the moment as X does not provide a means to do so.
