IIRC you can't do exactly what you'd like to do (i.e. impose a min freq). What should work is to force max performance mode and at the same time underclock. Then it should stay at the frequency you underclock it to and you might get reasonable heat/power consumption and reasonable performance. Of course it won't be adaptive any more..
Thanks for your reply~
I think this feature is not difficult to implement, and it is really very useful.
Maybe I don't know the way to configure the driver. I have read this
, and do some changes in device section in /etc/X11/xorg.conf
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2233; PowerMizerDefault=0x3; powerMizerDefaultAC=0x2"
0x33 in PerfLevelSrc means adaptive in AC mode.
But in this mode, poserMizerDefaultAC=0x2 will be ignored... So what I have done is useless.
