    If you want to use the kernel policies, look at the files
    in /sys/devices/system/cpu/cpu0/cpufreq.

    You can see which governors are available:

      $ cat scaling_available_governors
      ondemand userspace performance

    Also which governor is currently active:

      $ cat scaling_governor
      performance

    And of course you can change the active govenor:

      $ echo -n ondemand > scaling_governor
      $ cat scaling_governor
      ondemand

    Alternatively, you can use a userspace program like cpufreqd or
    powernowd to control the frequency. This allows much finer
    control, based on user-definable rules, battery status, a/c
    status, time, ...
