[PATCH V5 2/2] cpufreq: intel_pstate: Implement QoS supported freq constraints

2019-08-08 Thread Viresh Kumar
Intel pstate driver exposes min_perf_pct and max_perf_pct sysfs files, which can be used to force a limit on the min/max P state of the driver. Though these files eventually control the min/max frequencies that the CPUs will run at, they don't make a change to policy->min/max values. When the
