Como definir limites de escalonamento de CPU em todo o sistema

Question

Estou tentando fazer com que minha cpu fique em 2.0GHz (para manter a CPU legal XD) ou acima com um regulador conservador, para isso tentei configurar freqüências mínimas para minha CPU usando cpufreq-set

Eu preciso obter a frequência correta para limitar todos os cpu's a no mínimo 2,00 GHz ao usar o regulador On-Demand

Aqui estão algumas informações coletadas:

cpufreq-info -g
conservative ondemand userspace powersave performance

E todos os processadores retornam as mesmas informações do coufreq-info

  current policy: frequency should be within 1.20 GHz and 2.67 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.

Answer 1

Use os valores fornecidos com cpufreq-set

cpufreq-set -d 2.00 GHz
