Re: [Bug 1298966] [NEW] cpufreq and cpuidle output is confusing
This one is a tough one. I agree that to begin with the simplest approach
is to keep cpufreq and cpuidle stats completely separate. But I'd like to
see this report evolve to where we can have different outputs - idle stats
only, freq stats only and an intersection of idle and freq stats which
tells us what OPP we were running at when we went to some idle state. That
would allow easier correlation of policy tuning to observed behaviour.
