EDIT: my sincere apologies, this issue appears completely unrelated to Proxmox
EDIT 2: there were further changes I made (I went back and scoured through "the ultimate beginner's guide to pcie passthrough" found on reddit, following line-by-line) to the vm config before updating to the most recent driver and although it still didn't work until updating the driver this might help someone troubleshooting a similar setup. I had done everything else in that reddit thread previously and got passthrough working on Linux VM, so this might only be relevant to Windows or just a coincidence. Regardless, I added this line to the vm's conf file: args: -cpu 'host,+kvm_pv_unhalt,+kvm_pv_eoi,hv_vendor_id=NV43FIX,kvm=off'
I have read just about every post and tutorial on this issue. I know it's not proxmox as I've been able to pass this device through to a Linux guest, the only reason I switched to Windows guest was because of Steam limitations.
Card is the AMD RX6600.
Here is my config file:
I have configured IOMMU on the host, it is all working. I can see groups. Set acs override. The amdgpu drivers and blacklisted, along with all known drivers in fact. Interrupt remapping is enabled. The works.
I have even enabled hardware encoding and RemoteFX for rdp. Even though the VM boots with the PCI device attached, I cannot get the guest itself to view and use this card as default for love nor money.
At the point where I install the Radeon Adrenalin software, it says that it's incompatible with the graphics. I also cannot see the PCI device in device manager.
The error is as follows:
