    Default Power management on radeon git

    I'm on RV380 hardware (M22). System environment is Ubuntu Karmic with kernel, libdrm, xf86-video-ati and mesa at git master. The chip is running a lot hotter than normal in 2D desktop. And Xorg.log tells me that the PM options are unused. Are they completely disabled or is it KMS/DRI2 that are not allowing their use?

    xorg.conf:
    Code:
    Section "ServerLayout"
    	Identifier     "aticonfig Layout"
    	Screen      0  "Default Screen" 0 0
    EndSection
    
    Section "Files"
    EndSection
    
    Section "Module"
    	Load  "glx"
    EndSection

    The pm options are not available yet with kms.

    is there some ETA when it will be available with KMS? Or does it require the kernel side architecture for dynamic power management first?

    With kms enabled, the ddx (xf86-video-ati) no longer touches the hardware, so any missing features from the ddx need to be ported to the drm.
