Assigning priorities to Cx processor states

[Alexandre "Sunny" Kovalenko]

Good people,

is there way to assign priorities to Cx states, so, for instance 
C3 would be used more often at the price of performance degradation?

I would assume that cooking up _CST entry and lying about latency 
could possibly do the trick, but before I go that route, I'd rather
ask whether there is a better way.

Any feedback will be appreciated.
