Yeah, /proc/config.gz is a config option that you have to turn on. Also, my bad, that was the old command. Keep reusing that one by accident in my history lol. zgrep is a a better way of searching that .gz file (if it existed) instead of gzip piped to grep

Anyways, you can use the following:

$ grep -i 'cpufreq' /boot/config-$(uname -r)

That one worked! In the output I see:

CONFIG_X86_PCC_CPUFREQ=y
CONFIG_X86_ACPI_CPUFREQ=y
CONFIG_X86_ACPI_CPUFREQ_CPB=y

[perpetually high]

That one worked! In the output I see:

CONFIG_X86_PCC_CPUFREQ=y
CONFIG_X86_ACPI_CPUFREQ=y
CONFIG_X86_ACPI_CPUFREQ_CPB=y

What happens when you type:

$ modprobe acpi-cpufreq

Does it say any driver is loaded when you do "./phoronix-test-suite system-info" ?

Also, try a different kernel. Either the distro default, xanmod, etc and see if you get different behavior. 100% tied to your kernel most likely.

edit: also after you update-grub on intel_pstate=disable

Try the following RedHat suggestion:

Verify the presence of intel_pstate=disable parameter within the /proc/cmdline file:

# grep intel_pstate /proc/cmdline

There's no output. I'm using Xanmod and it oughtta work, but I will keep using Xanmod no matter what, so it I can't get schedutil to work on Xanmod, then so be it. Thanks for your help so far.
