Status:

# cpupower frequency-info
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
  hardware limits: 800 MHz - 1000 MHz
  available frequency steps: 1000 MHz, 800 MHz
  available cpufreq governors: conservative, userspace, powersave, ondemand, performance
  current policy: frequency should be within 800 MHz and 1000 MHz.
                  The governor "conservative" may decide which speed to use
                  within this range.
  current CPU frequency is 1000 MHz (asserted by call to hardware).
  boost state support:
    Supported: no
    Active: no

Set governor:

# cpupower frequency-set --governor [governor]
