frequency-info
--------------
analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 0.97 ms.
  hardware limits: 800 MHz - 3.10 GHz
  available cpufreq governors: performance, powersave
  current policy: frequency should be within 800 MHz and 3.10 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency is 1.68 GHz (asserted by call to hardware).
  boost state support:
    Supported: yes
    Active: yes
    2800 MHz max turbo 4 active cores
    2800 MHz max turbo 3 active cores
    3000 MHz max turbo 2 active cores
    3100 MHz max turbo 1 active cores
