    You can apply the patches yourself and build a new kernel.

    The article makes it seem like it hasn't even been added to kernel 6.8 how can we enable something that hasn't been added yet?

    I'm currently using v10 and it's enabled by default:
    Code:
    [niko@arch-phoenix ~]$ cat /sys/devices/system/cpu/amd_pstate/prefcore
    enabled​
    How can I tell what version I am running
