governor não pode ser definido

Question

RHEL 7.

Estou tentando definir o cpufreq_performance governor, mas, por algum motivo, ele não funciona:

[root@localhost]# cpupower frequency-set -g cpufreq_performance
invalid or unknown argument
[root@localhost]# cpupower frequency-info --governors
analyzing CPU 0:

Por que não consigo definir cpufreq_performance governor? Por que não consigo imprimir lista de governadores disponíveis?

É interessante, mas parece que meus processadores já estão operando com a frequência máxima do Turbo mesmo em sistemas inativos. CPUs abaixo são Xeon E5-2640 v1. se "Freq" é "atual", "vivo" valor então meu CPU é "turboboosted"

upd

[root@localhost]# cpupower frequency-set -g performance
Setting cpu: 0
Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
   for example because of hardware which cannot be set to a specific frequency
   or because the userspace governor isn't loaded?
