Hi everyone,
That some time I'm trying to change the scaling governor from performance to on demand. Every time I change it the server crash.
I have been searching some information about this and found that the amd pstate for zen2 and zen3 it's not manage correctly by the kernel.
by running dmesg | grep CPC I get the following result:
I have already check the bios and everything is activated. I have also tried to add amd_pstate.shared_mem=1 to grub but without result.
On this web site a patch is proposed to fix the amd pstate: https://bugzilla.kernel.org/show_bug.cgi?id=218171
So I tried to build a kernel using this repository https://github.com/proxmox/pve-kernel and adding the patch inside the folder patches/kernel. But I don't arrive to initialize submodules as they are not found.
That's my first time working and trying to build/patch a kernel, I'm a little bit lost and don't find a way to do it.
If someone have some advise or a tutorial to do it and be able to try this patch?
material and proxmox version:
amd thread ripper 3960x
proxmox 8.1.4
kernel 6.5.13-1-pve
