[PATCH v2 0/2] cpufreq: CPPC: idle cpu perf handling

Posted by Prashant Malani 3 months, 3 weeks ago

This is a short series to address the unreliable feedback performance
counter values that are returned by the CPPC driver when the CPU is
idle.

The first patch exposes idle_cpu() to be accessible to modules, and the
second patch does the actual change of not reading the feedback counters
when we know that the CPU is idle.
