[SOLVED] how to enable HuC on 6.11.0-1-pve kernel?

stuck · Dec 14, 2024

hello community,
I've been trying to enable HuC but judging by the fact that encoding using low power encoding inside my lxc is showing 80+% cpu utilization, leads me to believe it isn't working. Hw encoding (not using low power encoding) appears to be working fine.
All of the threads on this topic reference pinning to older kernel. But I need to be on 6.11 for my r8126 NICs to work. And most of the threads on this topic usually are passing into VMs which I don't really need.

Hoping someone can point me in the right direction to enable HuC. Please let me know if I can provide any more information to help answer this question...

my cpu is Ultra 5 125H on proxmox 8.3.1
grub isn't modified: GRUB_CMDLINE_LINUX_DEFAULT="quiet"

both the host and inside container show:

On the proxmox host this is what leads me to believe huc isn't loaded:

replacing the existing /lib/firmware/i915 with the ones from here:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
and adding 'options i915 enable_guc=3' to /etc/modprobe.d/i915.conf
Seem to have solved it.
