Tuning cpufreq governors does not work like described in
https://wiki.archlinux.org/index.php/CPU_Frequency_Scaling#Tuning_governors_.28with_cpupower.29

Because the governor is set after the commands in /etc/defaults/cpupower are executed the sysfs files do not exist at this point. # systemctl status cpupower cpupower.service - Apply cpupower configuration Loaded: loaded (/usr/lib/systemd/system/cpupower.service; enabled) Active: active (exited) since Sat 2013-06-01 17:36:35 CEST; 2min 5s ago Process: 275 ExecStart=/usr/lib/systemd/scripts/cpupower (code=exited, status=0/SUCCESS) Jun 01 17:36:35 spellcaster cpupower[275]: /etc/default/cpupower: line 34: /sys/devices/system/cpu/cpufreq/conservative/up_threshold: No such file or directory Jun 01 17:36:35 spellcaster cpupower[275]: /etc/default/cpupower: line 35: /sys/devices/system/cpu/cpufreq/conservative/down_threshold: No such file or directory Jun 01 17:36:35 spellcaster cpupower[275]: /etc/default/cpupower: line 36: /sys/devices/system/cpu/cpufreq/conservative/sampling_down_factor: No such file or directory Jun 01 17:36:35 spellcaster cpupower[275]: /etc/default/cpupower: line 37: /sys/devices/system/cpu/cpufreq/conservative/freq_step: No such file or directory Jun 01 17:36:35 spellcaster systemd[1]: Started Apply cpupower configuration. |
This task depends upon
I deleted it. Next time, you could fix the wiki by yourself, no need to open a bug report.
