CPU not scaling up in battery mode & incorrect Max frequency is displayed #436
Description
While using the laptop on battery , autocpu-freq doesn't scale the CPU's for some reason . It seems always stuck at the minimum frequency . My laptop is a low end dual core system so it causes pretty high performance drop , 1080p 60fps Youtube videos for example start having major framedrops . The CPU's don't scale up beyond the minimum frequency even when their usage reach 99%
Secondly i also noticed that the CPU max frequency info is incorrect . As you can see in the debug info below , it lists the max CPU frequency as 1.10GHz which is definitely incorrect , its 2.4Ghz as mentioned in the official page here , also while charging when performance mode is used it reaches upto that frequency frequently as clear from this stats here
I have disabled the intel_pstate & using the acpi-cpufreq driver as recommended in the troubleshooting guide . Just to cover the possibility that both of these issues could be related in any way , i have included them together here itself . Also i have installed auto-cpufreq using the official installer script just to rule out any rare possible issue exclusive to the arch package

Do the frequencies scale to their max potential if you install auto-cpufreq daemon using
--install_performance? Further reference.Although if it has the frequency wrong on both drivers then something else is at hand here ...

Just tested it after installing with
--install_performancebut it didn't seem to scale the CPU just like with the default installxd003 commentedon Sep 16, 2022
I think if proper logging is implemented then we can see what really is happening in real time so it could be easier to debug this issue seemingly faced by quite some people

I do agree that proper logging would be a great help (and a feature). But unfortunately I don't have time to look into this myself at this point, hence why if you (or anyone else) wants to give it a try, please do so and I'll gladly review your changes.
