+          This adds AMD-specific powersave bias function to the ondemand
+          governor, which allows it to make more power-conscious frequency
+          change decisions based on feedback from hardware (availble on AMD
+          Family 16h and above).
+
+          Hardware feedback tells software how "sensitive" to frequency changes
+          the CPUs' workloads are. CPU-bound workloads will be more sensitive
+          -- they will perform better as frequency increases. Memory/IO-bound
+          workloads will be less sensitive -- they will not necessarily perform
+          better as frequency increases.
