analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 10.0 us
  hardware limits: 2.00 GHz - 3.00 GHz
  available frequency steps:  3.00 GHz, 2.67 GHz, 2.34 GHz, 2.00 GHz
  available cpufreq governors: conservative userspace powersave schedutil ondemand performance
  current policy: frequency should be within 2.00 GHz and 3.00 GHz.
                  The governor "performance" may decide which speed to use
                  within this range.
