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
maximum transition latency: 4.0 us.
hardware limits: 800 MHz - 2.80 GHz
available frequency steps: 2.80 GHz, 2.20 GHz, 1.50 GHz, 800 MHz
available cpufreq governors: conservative, powersave, userspace, ondemand, performance
current policy: frequency should be within 800 MHz and 2.80 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
