2013-04-10cpufreq: AMD "frequency sensitivity feedback" powersave bias for ondemand ↵Jacob Shin
governor Future AMD processors, starting with Family 16h, can provide software with feedback on how the workload may respond to frequency change -- memory-bound workloads will not benefit from higher frequency, where as compute-bound workloads will. This patch enables this "frequency sensitivity feedback" to aid the ondemand governor to make better frequency change decisions by hooking into the powersave bias.
