BTW it would be even more useful if it could print some of the
statistics turbostat does (in particular frequency and C0 residency)
Often you only care about cycles not idle, and the frequency
tells you how fast the cycles happen.
I think Cx could be added relatively easily as a software event,
but frequency doesn't fit very well into the perf counting model,
as it's really sampling.
