#493 intel_lpmd.service should be enabled by default in Workstation installs

Reopen Issue

Some newer Intel laptop CPUs like Meteor Lake and Arrow Lake are multi-die / chiplet designs. These have 2 low-power-efficiency (LPE) cores in their IO-die, allowing fully powering down the CPU/compute die and running the system with just these 2 LPE cores.

The powering up/down of the compute die is not done automatically by the CPU or the kernel instead Intel has chosen to leave this up to userspace.

Intel has written a new daemon called LPMD to manage turning the CPU die on/off. This is packaged and installed by default for Fedora workstation installs.

But ATM the intel_lpmd service is not enabled by default, removing the option for some significant power-savings when the system is mostly idle.

Please add intel_lpmd.service to /lib/systemd/system-preset/80-workstation.preset so that users with these CPUs can enjoy these powersavings.

Is there a reason this shouldn't just be enabled globally? That way if the package is installed regardless of variant, it would be used.

We are also not automatically installing intel-lpmd in Fedora on any variant at the moment, at least I don't see it in @hardware-support or @workstation-product.

Right, this shouldn't be Workstation-specific.

Should we use 81-desktop.preset or should it be 90-default.preset?

90-default.preset. And the package needs to be added to @hardware-support.

This issue has been migrated to Fedora Forge:

Please continue any further discussion there.
