@rustybud

driver: intel_pstate governor: powersave

as expected ! powersave ! switch to ondemand or performance to solve your issue!
https://wiki.archlinux.org/title/Scaling_governor
and a way better: switch from intel_pstate to acpi-cpufreq handler that gives you more and better options for optimizing the system.

[rustybud]

@Olli

intel_pstate to acpi-cpufreq handler

Thank you for your fast reply. How do I switch from intel_pstate to acpi-cpufreq handler?

[Olli]

edit /etc/default/grub and insert

GRUB_CMDLINE_LINUX_DEFAULT="......intel_pstate=disable...."

to the existing ones. run

sudo mkinitcpio -P
sudo update-grub

reboot and check with inxi that acpi is the default handler afterwards. everything else can be found using a web-search of your choice and the arch-wiki-link i posted.

[rustybud]

Okay. I have done it and nothing has changed.

it has changed ! you’ll have to read it and it shows up that you have some really silly things in your pc. please check your bios settings for the cpu. a 12700 that detects only 0,4 GHz ? that’s pretty weird.

Maybe you skipped the forum tutorial? Please when you post Terminal code, mark this stuff with your mouse and press crtl+e or click on this </> ICON.

Our eyes are bleeding

@rustybud

Should I remove them?

Yeah remove them, they are outdated. At least this was my Info that i had found after i was looking for more informations about this 2 commands.

I removed them long time ago.

And merge your other .pacnew files.

Problem is still not solved.

[MrLavender]

You need to narrow down the issue. It’s not happening for anyone else so is it;

1. An issue specific to your system?
2. An issue specific to Manjaro?
3. An issue with linux 6.6?

I suggest download another distro live ISO that has the 6.6 LTS kernel, boot from that, and see if the problem is still there. E.g. MX Linux 23.2 “ahs”

If yes then it’s not a Manjaro issue and you need to look upstream for solutions. Try Slimbook technical support or their forum.

If no then it’s either Manjaro or something about your system configuration. Easiest way to test that is to boot from a Manjaro live ISO and see if it happens there. I think all of the current official ISOs (KDE, Xfce, GNOME) have 6.6 LTS.

[rustybud]

On Manjaro Live ISO Gnome with 6.6 LTS kernel this problem exists.
openSUSE Tumbleweed with 6.7 kernel this problem exists.

Ubuntu 23.10 with 6.5 kernel does not have this problem.
Fedora 39 with 6.5 kernel does not have this problem.

[MrLavender]

Ok, so it’s not a Manjaro or configuration issue.

For some reason linux 6.6 (and 6.7) seem to think that the max cpu speed is 2600 Mhz for every core and I have no idea where it is getting that from. It should be 4600/4700 for p-cores and 3500 for e-cores as it is in your inxi output for 6.1

I’m not sure how to debug this further because I don’t have an Intel cpu. One thing is for sure though, there is no way this is happening on every i7-12700H system or it would definitely have been noticed long ago.

Is this your laptop - Slimbook FEDORA 16 Intel i7 12700H? I’d try Slimbook support, possibly it’s a firmware bug?

[linux-aarhus]

The modern intel cpu with different core types may report very low numbers in inxi.

I bought last year Slimbook Executive 16 with Intel i7 12700H (predecessor of https://slimbook.com/en/executive)

[rustybud]

You have also an Intel hybrid CPU. Do you also have this issue?
What does your Geekbench scores look like on 6.1 LTS kernel and 6.6 LTS kernel on Manjaro?

[linux-aarhus]

@rustybud

What does your Geekbench scores look like on 6.1 LTS kernel and 6.6 LTS kernel on Manjaro?

I don’t know - this specific system is a specially handcrafted installation - using 6.6 - it would require too much work to install 6.1.

[stephane]

there is many troubles not solved with intel & P-core & E-core ( see change below in kernel 6.5 and more )
see theses
in linux 6.6 LTS there is this upgrade about workqueue, it prefers local cache ,

A pair of workqueue improvements [LWN.net]

or in case of rstybud , from lscpu -ae , you see for each cpu/smt the cache being used

question is , which ones are P-core or E-core , and which shares cache ,
for each cpu question is :

• is a P-core or a E-core
• what limit for each core
• what thermal limit for each core
