analyzing CPU 0:
  driver: powernow-k8
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 14.0 us.
  hardware limits: 800 MHz - 2.90 GHz
  available frequency steps: 2.90 GHz, 2.20 GHz, 1.70 GHz, 800 MHz
  available cpufreq governors: conservative, ondemand, userspace, powersave, performance
  current policy: frequency should be within 2.90 GHz and 2.90 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 2.90 GHz.
