analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1.20 GHz - 2.10 GHz
available frequency steps: 2.10 GHz, 2.10 GHz, 1.60 GHz, 1.20 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1.20 GHz and 2.10 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz.
cpufreq stats: 2.10 GHz:16.53%, 2.10 GHz:2.60%, 1.60 GHz:2.64%, 1.20 GHz:78.23% (415739)
