CentOS - CPUfreq governors

  • List available governors:
    # cpupower frequency-info --governors
    analyzing CPU 0:
    conservative userspace powersave ondemand performance
  • 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]
