Im using the following command to set my cpu to performance mode, but they reset back to default after a reboot.
echo "performance" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
How can I set it to performance permanently? Was reading the arch wiki (https://wiki.archlinux.org/index.php/CPU_frequency_scaling#Make_changes_permanent) but it seems like systemd related.
Im currently using artix base runit. Appologies if my question is stupid, first time linux user.
If your init system supports rc.local, you can put this command in it
/etc/rc.local ?
I've tried that already, it didnt work.

read it again and thoroughly, please! ;-)
Udev is not systemd, but udev!

Tip:
Since Linux 5.9, it is possible to set the cpufreq.default_governor kernel option.
Sorry, but I don't think I quite understand what Im supposed to do. I tried
/etc/modprobe.d/myfilename.conf
options acpi_cpufreq cpufreq.default_governor=performance
as well as
/etc/udev/rules.d/50-scaling-governor.rules
SUBSYSTEM=="module", ACTION=="add", KERNEL=="acpi_cpufreq", RUN+="/bin/sh -c 'echo performance > /sys/devices/system/cpu/cpufreq/policy*/scaling_governor'"
and none of them seem to work.
What have you for processor?
Put here log from lsmod
since kernel 5.9 you can add to your boot manager parameter
cpufreq.default_governor= performance https://wiki.archlinux.org/index.php/kernel_parameters for more details, depends on your boot manager (grub/syslinux/etc.)

I added
cpufreq.default_governor= performance in /etc/modprobe.d/myconfig.conf but that didn't work either.
Processor is 3700x and Im using grub as bootloader. Here's my lsmod.

EDIT: Followed these instructions (https://wiki.archlinux.org/index.php/kernel_parameters#GRUB) and added
cpufreq.default_governor=performance to /boot/grub/grub.cfg but that didn't work either. Not sure what Im doing wrong.
I added cpufreq.default_governor= performance in /etc/modprobe.d/myconfig.conf but that didn't work either.
Yes, that was wrong idea, when I wrote about boot manager 😂😂
I will try if it works for me.
Do you not use kernel-lts,or?
I installed the "linux" kernel (not the "linux-lts") and "linux-firmware" by following the wiki instructions (https://wiki.artixlinux.org/Main/Installation#Install_a_kernel)
adding "cpufreq.default_governor=performance"
(space was a typo!) in to boot manager as kernel parameter works absolutely perfectly!

Are you really re-generating the grub after editing?
grub-mkconfig -o /boot/grub/grub.cfg
put here your /boot/grub/grub.cfg. the mistake is somewhere on your side (you do things differently than the instructions)
I edited the /boot/grub/grub.cfg directly (without the space, figured it was typo) so I didn't regenerate the grub cfg.
This time I edited the /etc/default/grub instead and regenerated the cfg and my cpu is no longer at 2.2ghz after reboot, so it worked!
Thanks for your time and help. However Im a bit confused now, after regenarating and rebooting I looked at the /boot/grub/grub.cfg and it seems to be exactly how I manually edited it, how come manual edit didn't work? ??? Ahh, theres Artix Linux, Advanced options for Artix Linux and Artix Linux, with Linux linux (fallback initramfs) . I must have edited the wrong line.
