Questions related to AMD Reset Bug, GMKTEC M5 PRO, iommu groups #45

Hi first of all great turotial and great job. I finally manage to shared the igpu to my vm, but I got some questions to ge cleared out. Before that here is my setup details

Host

Hardware: GMKTEC M5 PRO
CPU: AMD Ryzen 7 5700U with Radeon Graphics
GPU: Radeon Graphics iGPU
RAM: 64GB DDR4 3200Mhz
OS: Proxmox VE

Guest

Processors: 4 (1 sockets, 4 cores) [host]
Machine: q35
BIOS: OVMF (UEFI)
DISPLAY: Default
PCI Device (hostpci0): 0000:05:00.1,pcie=1,romfile=vbios_5700U.bin
PCI Device (hostpci1): 0000:05:00.0,pcie=1,romfile=AMDGopDriver_5700U.rom
OS: Debian 12

From the VM i can see that the iGPU is passed and Debian got it with the drivers (sudo apt install firmware-amd-graphics). Now I got some questions to be clarified.

Questions

  1. Do i need to install AMD Reset Bug Fix for Linux too? I think not
  2. If i am not wrong the iGPU is a full passthrough which means the host will have no display output after boot right? I think yes
  3. For the Guest VM getting the iGPU should i keep the DISPLAY: Default as it is or something else? This i have no idea
  4. Is it necessary to to passthrough the Audio device too? I see that the iGPU and Audio are two different iommu groups.
