Description

Is this a new report?

Yes

System Info

Void 6.5.2_1 x86_64 GenuineIntel notuptodate FFF

Package(s) Affected

thermald-2.5.4_1

Does a report exist for this bug with the project's home (upstream) and/or another distro?

No response

Expected behaviour

thermald is not supposed to affect performance this much.

Actual behaviour

Hello, I've encountered an issue with thermald, I don't know if we could really call this a bug but thermald needs some ACPI info about max temperatures on newer laptops/ultrabooks.

The ACPI info was not read, so on my laptop thermald would throttle heavily (cf. https://www.reddit.com/r/voidlinux/comments/16gtkl5/whole_system_slower_with_dbus_service/?utm_source=share&utm_medium=web2x&context=3)

Upstream people have added the "--adaptive" option to thermald. I simply added this option in the runit run file.

Up to you to decide if this should be distributed on void-packages.

The thermald help does say "adaptive mode: use adaptive performance tables if available", so it shouldn't affect users who miss it.

Should we add this option ?

Steps to reproduce

Hardware specific bug
enable dbus service
enable thermald service
lower performances.

enable dbus service
enable thermald service with --adaptive
no performance issue.

Research direction

Inspect the thermald runit run file and compare the service command with the reported --adaptive invocation. Test thermald with and without that option on the affected setup; done means the service uses adaptive mode and no longer causes the reported performance loss.
