Zunächst müssen Sie mit dem Befehl apt-get install cpufrequutils eine Reihe notwendiger Dienstprogramme auf dem System installieren. Eines davon, nämlich cpufreq-info, ermöglicht es Ihnen, herauszufinden, welche Richtlinie zur Frequenzdrosselung derzeit verwendet wird:
analyzing CPU 0:
driver: acpi-cpufreq
CPUs that run at the same hardware frequency: 0 1 2 3 4 5 6 7
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0us.
hardware limits: 800 MHz - 3.30 GHz
available frequency steps: 3.30 GHz, 3.30 GHz, 3.10 GHz, 2.90 GHz, 2.80 GHz, 2.60 GHz, 2.40 GHz, 2.20 GHz, 2.00 GHz, 1.90 GHz, 1.70 GHz, 1.50 GHz, 1.30 GHz, 1.20 GHz, 1000 MHz, 80 MHz
available cpufreq governors: userspace, power save, conservative, on-demand, performance
current policy: frequency should be between 800 MHz and 3.30 GHz.
The governor's "on-demand" may decide which speed to use
within this range.
the current CPU frequency is 800 MHz (asserted by call to hardware).
cpufreq stats: 3.30 GHz:0.04%, 3.30 GHz:0.00%, 3.10 GHz:0.00%, 2.90 GHz:0.00%, 2.80 GHz:0.00%, 2.60 GHz:0.00%, 2.40 GHz:0.00%, 2.20 GHz:0.00% , 2.00 GHz:0.00%, 1.90 GHz:0.00%, 1.70 GHz:0.00%, 1.50 GHz:0.00%, 1.30 GHz:0.00%, 1.20 GHz:0.00%, 1000 MHz:0.00%, 800 MHz:99.96% (5 )
