I was able to reproduce the problem from the shell

-bash: echo: write error: Device or resource busy

# echo performance > /sys/devices/system/cpu/cpu15/cpufreq/energy_performance_preference

@Angel-Karasu this looks like a problem introduced in #736 as I remember changes to print(f"ERROR: failed to read battery thresholds: {e}

arcenik · 2024-07-17T10:21:32Z

After disabled amd_pstate the log spam problem is fixed.

Another way to fix this could be to use performance instead of balance_performance

Or validate the values found in energy_performance_available_preferences

Angel-Karasu · 2024-07-17T10:31:32Z

@Angel-Karasu this looks like a problem introduced in #736 as I remember changes to print(f"ERROR: failed to read battery thresholds: {e}

There is an error because the version of auto-cpufreq in the AUR isn't up to date, we can see it uses the method to read battery threshold before #716

In that case tagging AUR package maintainers ... @MusicalArtist12, @liljaylj, @parmjotsinghrobot

I'll update it tonight

kralle333 · 2024-08-23T08:29:13Z

seeing similar issue, installed using latest version from master

armenr · 2024-09-05T21:43:48Z

I've installed from the master git branch - getting this same issue on my machine.

But, when I run auto-cpufreq --stats I do see what appears to be the correct output:

PC    ➜  LENOVO Yoga Pro 7 14IMH9 Type 83E2

AdnanHodzic · 2024-09-06T05:42:06Z

This seems like an identical issue as in #765 and issue was solved in #750 however PR with fix was never submitted ... hence if anyone would like to give it a try and contribute to the project and you will be credited for your work as part of future release.

Xenapte · 2024-09-13T21:42:57Z

Same issue for me except that it's on line 99. With the latest AUR release (2.4.0-1) on a ThinkBook laptop.

Hi, same issue :(
someone can help us ?
(I don't know if it's related, but I enabled secure boot recently, and updated the kernel, is it related?)
