New kernel patches by AMD for the Linux kernel provide "frequency sensitivity feedback" for the powersave bias in cpufreq. This hardware feedback feature is to be introduced on future AMD processors. This patch-set allows the system to make more power conscious frequency changing decisions based upon hardware feedback. The hardware bits are to be found on "AMD Family 16h" processors and above, which is the forthcoming AMD "Jaguar" product. AMD provided the original Linux kernel support for "Family 16h" at the end of 2012.
