analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 800 MHz - 2.50 GHz
available frequency steps: 2.50 GHz, 2.50 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz, 800 MHz
available cpufreq governors: powersave, conservative, userspace, ondemand, performance
current policy: frequency should be within 800 MHz and 2.50 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
current CPU frequency is 800 MHz.
