Was kann ich tun?
/etc/sysfs.conf funktiniert leider nicht...

mode class/powercap/intel-rapl:0/energy_uj = 0440
owner class/powercap/intel-rapl:0/energy_uj = root:power

Re: ERROR: Failed to open file for read

Und wir bist Du auf den Ansatz gekommen?
https://wiki.archlinux.org/index.php?search=sysfs.conf
https://michael.stapelberg.ch/posts/201 … _obsolete/
https://wiki.archlinux.org/title/Udev#udev_rule_example

Und nur zur Sicherheit:

stat /sys/class/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:0/energy_uj
id

Re: ERROR: Failed to open file for read

Ich hab die sysfs.conf mit diesem Inhalt angelegt und der Fehler besteht immer noch, also scheint die sysfs.conf Wirkungslos zu sein!?

Re: ERROR: Failed to open file for read

Ich habe die udev Regel von hier genommen https://serverfault.com/questions/11239 … g-owner-ha
99-gamemode.rules

ENV{SUBSYSTEM}=="powercap", ACTION=="add|change", OWNER="root", PROGRAM+="/usr/bin/find /sys$env{DEVPATH} -name energy_uj -exec chmod g+r -R {} + -exec chown root:powercap {} +"

Es scheint zu funktionieren...
Ich habe zu wenig Wissen über udev, so dass ich nicht sagen kann, ob das, eine saubere Lösung ist.
Für Vorschläge bin ich jeder Zeit offen

udev hat eine eingebaute Möglichkeit, Besitzer und Berechtigungen zu setzen: https://wiki.archlinux.org/title/Udev#A … se_devices
