Last week I did a fresh proxmox install with uefi. Later I built a windows vm with uefi. I am now attempting gpu passthrough.
- I have disabled the gpu on boot via vfio.
- Patched grub with iommu for intel
- I have disabled drivers, per the gpu passthrough wiki article via modprobe.d
- I have enabled the current and most accurate msi rom for my driver (which seemed to help it bios post)
- I have installed rx 480 drivers on the windows vm
- Yet the device is code 46 in windows, crashed, and doesn't post windows screens
