Okay so I'm new here guys, just made a fresh Gentoo install. Tweaked the kernel and other settings until I finally have a fully working setup with touchpad, sound, etc. working flawlessly. Ran into a lot of issues but slowly fixed them one by one thanks to the valuable resources in this forum and various wiki.

Anyway, first of all I'd like to mention that for some parts of the system like the Signal processing controller or the Encryption controller has no modules loaded. Before Gentoo I was running Arch and it seemed to have modules loaded, although I don't actually remember what they were but it was something along the lines "mei_*".

Here's the output

I'm not that experienced with hardware or with Gentoo for that matter so I'm not sure if this is something that I should be worried about.

Also another thing is power management, on arch the power usage was around 3.6 W and here it's roughly around 4W. I've installed tlp from gentoo overlay, configured it for optimum settings and also applied intel power saving flags as boot parameters. I've seen on Gentoo wiki that cpu-frequtils it recommended over intel_pstate driver but currently I have intel_pstate so should I consider switching to cpu_frequtils?

Also I compiled kernel using gen kernel with menuconfig and instead of fully dynamic ticks (which I ran into with issues), I set it to idle_ticks at the moment.

Please give me some suggestions as to what to do, thanks.

irenicus2015 ... welcome to gentoo. Probably 'mei_txe'. You can have it load via /etc/conf.d/modules, eg (for 4.x series kernels):

/etc/conf.d/modules:
modules_4="${modules_4} mei_txe"
#module_mei_txe_args_4=""

You seem to be confusing kernel drivers with userland, the userland component is sys-power/cpupower, cpufreqd/cpufreq-utils are now depreciated. As for X86_INTEL_PSTATE and CPU_FREQ_GOV I can't say which is better for modern cpu's, I'm still x86 (and so using CPU_FREQ_GOV_ONDEMAND).

HTH & best ... khay
