Merge branch 'pm-cpuidle'
* pm-cpuidle: cpuidle: sysfs: Export target residency information intel_idle: fine-tune IVT residency targets tools/power turbostat: Run on Broadwell tools/power turbostat: simplify output, add Avg_MHz intel_idle: Add CPU model 54 (Atom N2000 series) intel_idle: support Bay Trail intel_idle: allow sparse sub-state numbering, for Bay Trail ACPI idle: permit sparse C-state sub-state numbers

the arithmetic average of the GHz column above is lower.

This is a weighted average, where the weight is %c0. ie. it is the total number of

Note that the Avg_MHz column reflects the total number of cycles executed
|
||||
divided by the measurement interval. If the %Busy column is 100%,
|
||||
then the processor was running at that speed the entire interval.
|
||||
The Avg_MHz multiplied by the %Busy results in the Bzy_MHz --
|

which is the average frequency while the processor was executing --

not including any non-busy idle time.
