I was try passthrough intel gpu in pve, following by a blog:https://www.derekseaman.com/2023/11/proxmox-ve-8-1-windows-11-vgpu-vt-d-passthrough-with-intel-alder-lake.html

my environment：
CPU： N100
PVE： 8.2.2
Kernel： 6.5.13-3-pve

I have a same typeof cpu with this blog (N100-N305, 12 gen alder lake)，same kernel，but i have this error, I not really good at linux, chatgpt give me nothing but crap, can anybody give me a hand.
by the way, if you need more info, I will reply very soon, I been doing this for weeks and I’d to die.
