Report errors and bugs to cpufreq@email-addr-hidden, please.
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: 800 MHz - 2.00 GHz
available frequency steps: 2.00 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz,
800 MHz
available cpufreq governors: userspace, powersave, conservative,
ondemand, performance
current policy: frequency should be within 800 MHz and 1.20 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
cpufreq stats: 2.00 GHz:0.00%, 2.00 GHz:0.00%, 1.60 GHz:0.00%, 1.20
