Ravi-Kishor commented 1 year ago

please add "schedutil" cpu governer too...its too useful in saving batter on laptops, I use auto-cpufreq tool from github to auto switch scheduler, so having schedutil will be a great thing. please consider this in nect update.

schedutil was removed from Liquorix due to massive performance issues that were discovered during Phoronix testing. Not only does it have a bad interaction with PDS/MuQSS, but its focus on efficiency defeats the purpose of Liquorix.

Now you may be asking, why not leave it as an option? The answer is it was an option and the default is performance. The problem is most distributions configure their cpufreq daemons to force schedutil if they see it, degrading the experience running Liquorix. The fix is to obviously just remove it since not only is it a bad fit for Liquorix, but when a distribution overrides the governor to schedutil, the kernel performs worse than stock.

I recommend using ondemand, you'll get the battery life you're looking for and performance at the same time.

Try intel_pstate (I assume your laptop uses an Intel CPU) if you do need something "works like" schedutil. Note that Liquorix has it disabled by default.
