analyzing CPU 0:
  driver: amd-pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 20.0 us.
  hardware limits: 400 MHz - 3.80 GHz
  available cpufreq governors: conservative, ondemand, userspace, powersave, performance, schedutil
  current policy: frequency should be within 400 MHz and 3.80 GHz.
                  The governor "schedutil" may decide which speed to use
                  within this range.
  current CPU frequency is 4.19 GHz.
