Intel B580 GPU PassThrough

[jpcapone]

Passing through the Intel B580 is becoming an unhealthy obsession for me. I have tried to pass it through to an lxc to no avail. Now i am trying to pass it through to a VM following every guide I could find and still no dice. For the record, I have installed and reinstalled proxmox so many times over the past week that I can flash my system and have it up and running in 10 minutes. I have a few questions for the people that seem to have done this successfully. Focusing on VM GPU passthrough:

1. Is it necessary to upgrade my proxmox kernel? Currently at 6.8.12-9-pve I have tried 6.11 up to 6.14 to no avail.
2. Do I need to install the drivers on the host? I am just checking as it doesnt seem like it.
3. Do I need anything in my grub.cfg other than this "GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"?
4. Also, when passing through do you use Raw Device?

Currently i am not even seeing it on the host.

******EDIT
Made some progress

root@proxmox:~# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Arrow Lake-S [Intel Graphics] (rev 06)
03:00.0 VGA compatible controller: Intel Corporation Battlemage G21 [Arc B580]

root@proxmox:~# uname -r

I updated the the kernel and I swear it took several reboots for the change to take effect but there it is.
Moving forward with the actual passthrough.
