We've generally been assuming (rightly or wrongly) that getting into
deep C states is preferable to being active (even at a lower frequency),
and so the current behaviour of tending to rapidly switch to the maximum
P state isn't inherently a problem. What kind of power savings are you
benchmarking with this, and do you still see a saving if you just
disable turbo mode?
