Strange I even don't have the /etc/default/cpufrequtils.
analyzing CPU 7:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1 2 3 4 5 6 7
CPUs which need to have their frequency coordinated by software: 7
maximum transition latency: 10.0 us.
hardware limits: 800 MHz - 2.20 GHz
available frequency steps: 2.20 GHz, 2.20 GHz, 2.10 GHz, 2.00 GHz,
1.90 GHz, 1.80 GHz, 1.70 GHz, 1.60 GHz, 1.50 GHz, 1.40 GHz, 1.30 GHz,
1.20 GHz, 1.10 GHz, 1000 MHz, 900 MHz, 800 MHz
available cpufreq governors: conservative, userspace, powersave,
ondemand, performance
current policy: frequency should be within 800 MHz and 2.20 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).
cpufreq stats: 2.20 GHz:7.51%, 2.20 GHz:0.01%, 2.10 GHz:0.01%, 2.00
GHz:0.01%, 1.90 GHz:0.00%, 1.80 GHz:0.00%, 1.70 GHz:0.01%, 1.60
GHz:0.00%, 1.50 GHz:0.01%, 1.40 GHz:0.00%, 1.30 GHz:0.02%, 1.20
GHz:0.03%, 1.10 GHz:0.01%, 1000 MHz:0.00%, 900 MHz:0.03%, 800 MHz:92.35%
