Hi, I feel like i've searched far and wide for every solution so i'm turning here. I've looked through many an article and from what i can understand I believe the issue lies in my VM

(proxmox 8.4.17)
im using an A380 as a secondary gpu that im attempting to passthrough into a debian 13 vm
So lets get through all the settings i think are right
bios resizable bar is on
AMD cpu iommu appears to be on

ive got the 4 modules like here. /etc/modprobe.d/blacklist.conf same. etc/modprobe.d/vfio.conf similar didn't add the audio device there
the gpu seems to be using the right kernel driver1773889225730.png
Im passing both the portions of the A380 that i can see

acpi is off
using q35 and uefi
memory ballooning off

This is where my main issue is i believe the i915 kernel module won't load
