Incorrect Platform Profile List: low-power vs quiet

[ikus060]

The list of available platform profiles on my system is incorrect. It should include "quiet", but instead, it displays "low-power", which is not available on my system.

Expected Behavior

The system should list only the profiles that are actually available, as defined in /sys/firmware/acpi/platform_profile_choices.

Actual Behavior

The system incorrectly shows "low-power" as an option, even though it is not listed in /sys/firmware/acpi/platform_profile_choices.

+++ Platform Profile
/sys/firmware/acpi/platform_profile                    = balanced
/sys/firmware/acpi/platform_profile_choices            = quiet balanced performance

Suggested Fix

From a quick review of the code, it seems that the list of available profiles should be retrieved dynamically from /sys/firmware/acpi/platform_profile_choices, rather than using a predefined list of values. This would ensure that only valid options are presented to the user.

Hi,
yes that should be considered. The only issue I see is that some systems might have a different way to switch power profiles.
I have a Dell system here that supports power profiles via smbios-thermal-ctl but not via /sys/firmware/acpi/platform_profile. There it is supported only after updating to kernels >6.11.

But you are right, I will set the selected option in the UI if available in tlp-stat -p. Try to fix this soon.
