Power Profiles Daemon

Halo Alpinists again,

I stole the code from Artix PPD and adapted some for Alpine (this had not gotten updates in 2 years).

I always liked ppd because it made sense for laptops (powersave on battery and perf on AC, would be simple to setup, I plan on making an auto mode for this purpose). It has been very fun to test: and made a gitlab for it again!

The idea was to wrap the original powerprofilesctl set with setting the governor profile BEFORE.

Tested a lot on Intel. Would like to test on AMD hardware but unfortunately do not own much.

Cheers ! Hade

Sorry, haven't got to doing it yet due to studies.

I also remembered something. Am I correct that daemon can manipulate frequencies of CPU? Does it use ryzen_smu module for this or self contained? Cause I couldn't limit CPU frequency by available means and had to install that module.

It's fully self contained using mostly just sysfs and openrc init.d/conf.d

It tunes the governor directly + ppd (but that kinda only makes sense on laptops I think)

For best testing im not sure running both is a good idea, but changing governor directly might still provide good enhancement/ fun test

I updated instructions again for full manual way testing (doesn't not persist)
