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: 10.0 us.
hardware limits: 2.00 GHz - 3.00 GHz
available frequency steps: 3.00 GHz, 2.67 GHz, 2.34 GHz, 2.00 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 2.00 GHz and 3.00 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 2.00 GHz.
