[Intel-gfx] reducing GM965 power usage when using inteldrmfb

[Ali Gholami Rudi]

Hi,

I have a mobile intel GM965 chip.  Is it possible to activate
FBC or reduce the clock frequency without using xorg (when using
only inteldrmfb)?  As far as I can tell, the xorg driver performs
at least a few ioctl()s to activate FBC.

Thanks,
Ali
