analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 0 1
  hardware limits: 800 MHz - 1.73 GHz
  available frequency steps: 1.73 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
  available cpufreq governors: ondemand, userspace, powersave, performance
  current policy: frequency should be within 800 MHz and 1.73 GHz.
                  The governor "userspace" may decide which speed to use
                  within this range.
  current CPU frequency is 1.73 GHz.
