So i should leave this commented then because it’s now controlled by the kernel?
Edit: I get this when run.
[ricklinux@eos-plasma ~]$ cpupower frequency-info
analyzing CPU 12:
CPUs which run at the same hardware frequency: 12
CPUs which need to have their frequency coordinated by software: 12
maximum transition latency: Cannot determine or is not supported.
hardware limits: 550 MHz - 4.56 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 550 MHz and 4.56 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 3.46 GHz (asserted by call to kernel)
boost state support:
I’m not using it… I would leave it commented since governor “ondemand” is not available anymore for amd_pstate_epp, Actually, cpupower does not even show the options we are using now as available in that config file…
I suppose that cpupower.service is failing to launch because of that… You probably set a governor that amd_pstate_epp doesn’t support.
Since those options (balance_power balance_performance…) are not available for cpupower, I thought maybe one could switch between them using powerprofilesctl. But it doesn’t seem so …
powerprofilesctl COMMAND [ARGS…]
help Print help
version Print version
get Print the currently active power profile
set Set the currently active power profile
list List available power profiles
list-holds List current power profile holds
launch Launch a command while holding a power profile
hmm, thanks… It seems that for Gnome that option is located in the left upcorner menu.
It is set to balanced here, but if I change it to performance, nothing happens.
I suppose its main purpose is for devices that use a battery…
Changed the option from balanced to performance in Gnome and now I can see this:
$ cat /sys/devices/system/cpu/cpufreq/policy0/energy_performance_preference
$ powerprofilesctl list
But according to cpupower frequency-info and watch -n1 "grep \"^[c]pu MHz\" /proc/cpuinfo" , it seems that nothing changed…
