CPU Frequency Scaling - only 2 Scaling governors optiones.

Hello. I have asus R500 laptop. I used powersave Scaling on ubuntu, but in arch i have only 2 governors.

cpupower frequency-info
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0 1 2 3
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 10.0 us.
  hardware limits: 1.20 GHz - 2.50 GHz
  available frequency steps: 2.50 GHz, 2.50 GHz, 2.40 GHz, 2.30 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
  available cpufreq governors: ondemand, performance
  current policy: frequency should be within 1.20 GHz and 2.50 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 1.20 GHz.
  boost state support:
    Supported: yes
    Active: yes
    25500 MHz max turbo 4 active cores
    25500 MHz max turbo 3 active cores
    25500 MHz max turbo 2 active cores
    25500 MHz max turbo 1 active cores

cpupower missing cpufreq_powersave and cpufreq_conservative. For scaling cpu i use CPU Freq gnome-shell.
Do u know how to enable cpufreq_powersave?

Re: CPU Frequency Scaling - only 2 Scaling governors optiones.

You need to load cpufreq_powersave kernel module first.

Re: CPU Frequency Scaling - only 2 Scaling governors optiones.

you can load modules manually (as root) with : modprobe somemodule .

If you want to have them loaded always at boot, see the systemd wiki page.

Booting with apg Openrc, NOT systemd.
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them
