Corectrl will not allow overlock/undervolt after updating kernel

Issues & Assistance
1

This started today when i attempted to install the most recent updates to the kernel.

current stable: 6.4.4-AMD-znver2

when i attempted to update to kernel 6.4.v.6-1, it breaks corectrl, and then will not allow corectrl to adjust the timings. once i restored (thanks again snapper) i'm back to where i started.

i do not see any updates to corectrl.

New to garuda, just come from pop_os! 22.04 with Xanmod or Liquorix kernels'.

what do?

Try other kernel

sudo pacman -S linux-zen linux-zen-headers

and boot it via grub - advanced.

well, i did, i tried several others, none worked. neglected to mention that in my original post. i did however forget to RTFM, and according to Setup · Wiki · CoreCtrl / CoreCtrl · GitLab you must append the following to your /etc/default/grub file specifically the GRUB_CMDLINE_LINUX_DEFAULT= Section;

If your system uses Grub, edit the file (as root) /etc/default/grub and append the parameter to GRUB_CMDLINE_LINUX_DEFAULT:

GRUB_CMDLINE_LINUX_DEFAULT="<other_params>... amdgpu.ppfeaturemask=0xffffffff"

Then regenerate (as root) the bootloader configuration file with the command:

grub-mkconfig -o /boot/grub/grub.cfg

Reboot your system.

so to review;

old config of /etc/default/grub

....
GRUB_CMDLINE_LINUX_DEFAULT='quiet quiet rd.udev.log_priority=3 vt.global_cursor_default=0 loglevel=3' # Modified by garuda-migrations: splash

new config of /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT='quiet quiet rd.udev.log_priority=3 vt.global_cursor_default=0 loglevel=3 amdgpu.ppfeaturemask=0xffffffff' # Modified by garuda-migrations: splash

what was confusing to me, was that i didn't have amdgpu.ppfeaturemask=0xffffffff in my grub file in the previous kernel version. so it wasnt something i thought of right away. is there something missing? either way, its working now for those that google this later!!

Corectrl came with this disro, so i didn't have to pull it from somewhere, and it was able to load/control my timings without the edited grub, but dropped once the kernel was updated. curious as to what that could be and was that by design?
