   Had a question about "BIOS GT RC6 option". If I disabled the BIOS GT 
RC6 option, does that mean RC6 will be disabled no matter how driver 
configure RC_CONTROL registers on core platform?

Looks currently on some SoC platform e.g. BXT, the status of "BIOS GT 
RC6 option" will be reflected in the default value of RC_CONTROL or 

How about the core platform? As I didn't see the similar logic, I guess 
there should be some other kinds of approach here? :)
