cpupower-gui performance profile is not persistent.

[panorain]

Hi, when I set cpupower-gui to use Performance setting at boot and apply. A reboot reverts back to Scedutil governor. I am able to manually set cpupower-gui to use performance settings again. Why is Performance setting or a custom profile not persistent? Is the problem related to a permission issue perhaps?

/home/pj/.config
 drwx------ 1 pj pj   86 Jan 25 10:38 cpupower_gui

~/.config/cpupower_gui> ls -lah total 8.0K drwx------ 1 pj pj 86 Jan 25 10:38 . drwx------ 1 pj pj 3.6K Mar 10 01:44 .. -rw-r--r-- 1 pj pj 140 Mar 10 01:39 00-cpg.conf -rw-r--r-- 1 pj pj 114 Jan 25 10:38 cpg-Lenovo-M57p-Profile1.profile

To Reproduce Steps to reproduce the behaviour:

1. Set cpupower-gui to use performance setting at boot and apply.
2. Powercycle/Restart - Machine
3. Notice cpupower-gui has reverted to using the Schedutil governer option

Expected behaviour I expected cpupower-gui to allow for persistent performance setting once machine is powercycled.

Setup (please complete the following information):

• Distro: openSUSE Tumbleweed
• Package version: 1.0.0+git.24.b44a198-1.1
• Installed via: [package or source]
• Source package : cpupower-gui-1.0.0+git.24.b44a198-1.1.src
• Vendor : obs://build.opensuse.org/multimedia
• Arch : noarch

Additional context Thank you for the nice program.

check that cpupower-gui systemd service is working : systemctl status cpupower-gui

do you have tlp installed ? some programs set intel p-state to passive after cpupower applys the profile. which overwrites governor to scedutil.

Thank you for responding, Between the time I wrote my initial message and hearing from you this > https://github.com/vagnum08/cpupower-gui#system-configuration-and-user-profiles < did not work for me. Please do feel free to discuss this if you have further questions as to why. I can display the current configuration file contents on the machine if desired.

tlp is not installed on this machine. This is a desktop machine. How can I find out more about which program could be setting the intel p-state to passive?

I created a systemd service with a script and able to set persistent ondemand governor mode this way now (I think). I'm using ondemand not performance governor for now.

1. Create service file in directory /etc/systemd/system named > cpupower-ondemand-governor.service
2. File permissions are > -rw-r--r-- 1 root root 316 Apr 20 23:23 cpupower-ondemand-governor.service
3. Service file contents > /etc/systemd/system > cat cpupower-ondemand-governor.service [Unit] Description=Enable cpupower-ondemand-governor on this machine After=multi-user.target

   graphical.target - multi-user.target

[Service] Type=oneshot RemainAfterExit=true StandardOutput=tty ExecStart=/usr/local/sbin/cpupower-ondemand-governor.sh

[Install] WantedBy=multi-user.target WantedBy=graphical.target

4. Create script file in directory /usr/local/sbin named > cpupower-ondemand-governor.sh
5. File permissions are > -rwxr-xr-x 1 root root 206 Apr 20 23:20 cpupower-ondemand-governor.sh
6. Script file contents are > /usr/local/sbin > cat cpupower-ondemand-governor.sh

   !/bin/bash

   cpupower frequency-set --governor ondemand echo "the script works" >> /tmp/cpupower-ondemand-governor.txt logger -t cpupower-ondemand-governor.sh -p local1.info "Enabling ondemand-cpu-governor"

What are your thoughts about this? Why does passing systemctl status cpupower-gui display the schedutil governor still being used? When I open the cpupower-gui application from the KDE6 menu the Ondemand governor is being selected by default now.

Active: inactive (dead) since Mon 2024-05-27 20:38:27 CDT; 8h ago

you have an issue here

the service should be always active.

 set persistent ondemand governor

it should never be persistent, this way there might be two apps opposing each other trying to change governor.

the issue is that on boot an app changes CPU governor from active (performance or power-save) to passive (where the default is Scedutil .

to revert this try : echo "active" | sudo tee /sys/devices/system/cpu/intel_pstate/status confirm to me if this worked with you.

Hi, I believe what you say is to disable/remove the service I created. It is like a bad patch.

There is no intel_pstate directory on this machine : :~> echo "active" | sudo tee /sys/devices/system/cpu/intel_pstate/status [sudo] password for root: tee: /sys/devices/system/cpu/intel_pstate/status: No such file or directory active

This does not appear to work.

my bad too, there must have been some misunderstanding.

what is your cpu?

for me cpupower-gui also isn't persistent, i tried on linux mint 22 xfce and on manjaro linux
