Description Hans de Goede 2025-01-14 20:35:05 UTC

As far as I know the intel-lpmd daemon needs to be installed and running and meteorlake laptops to ensure that "Low Power Mode" is entered when the system is idle. This switches off the main CPU/compute chiplet to save power and leaves the system running on the 2 special LPE cores in the IO chiplet.

But after installing F41 workstation on a Lenovo ThinkPad X1 Carbon gen 12 which has a Meteor Lake CPU intel-lpmd was not installed and after installing it, it was not enabled by default.

I believe that intel-lpmd should be added as a default package to the hardware-support group in comps, see:

https://www.pagure.io/fedora-comps/c/d650f69cf9b7959a7ad2287bbf8f4d03bcebf3c1?branch=main

for an example comps commit doing something similar.

Likewise I believe that at least in Fedora workstation a systemd-preset should be added which enables the intel-lpmd service by default, see:

https://docs.fedoraproject.org/en-US/packaging-guidelines/DefaultServices/


Reproducible: Always

You can request that packages be added to the default install here: https://pagure.io/fedora-workstation/issues

That said, I wonder why is this a new daemon and not just added to tuned and power-profiles-daemon?

I see it's too big and probably really does need to be its own daemon. Sigh.

Next question: why can't this go into the kernel directly?

This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.

Comment 4 Adam Williamson 2025-12-02 02:09:41 UTC

This message is a reminder that Fedora Linux 41 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 41 on 2025-12-15.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '41'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 41 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 5 Hans de Goede 2025-12-02 08:57:29 UTC

This is still relevant, changing release to rawhide

It looks unlikely that Ali is going to fix this though.

I've filed a fedora-workstation issue for this as suggested in comment 2 :
