Hi, I have an HP Prodesk 405 G4 which has an AMD Ryzen 5 PRO 2400GE CPU with a Vega RX 11 iGPU. Before trying it, I'd like to know if setting up Proxmox on this machine for the purpose of having a VM that gets the iGPU passed through (amongst some more LXCs) is even valid as I don't think the IOMMU groups are in my favor. Please have a look:
As you can see, there are only 4 IOMMU groups. For the iGPU I'd have to pass the entire group 1. I wouldn't mind passing all the USB ports or the audio devices. But I am worried about the SATA controller or the PCI bridges. Would it still work? I don't think so. Or is there a method to pass only the iGPU?
