analyzing CPU 0:
  driver: powernow-k8
  CPUs which need to switch frequency at the same time: 0 1
  hardware limits: 1000 MHz - 2.00 GHz
  available frequency steps: 2.00 GHz, 1.80 GHz, 1000 MHz
  available cpufreq governors: ondemand, userspace, performance
  current policy: frequency should be within 1000 MHz and 2.00 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 2.00 GHz (asserted by call to hardware).

# Busy percentage threshold over which to scale up to max frequency
# default value: empty (use governor default)
UP_THRESHOLD=50
# Busy percentage threshold under which to scale frequency down
# default value: empty (use governor default)
