But Kash is right. I have a AMD Radeon RX 480 and it works flawlessly with the Q35 chipset. My PCIe hierarchy: qemu-kvm ... \ -M q35 ... -device ioh3420,bus=pcie.0,multifunction=on,port=1,chassis=1,id=root. ... -device vfio-pci,host=01:00.0,id=hostdev0,bus=root.0,multifunction=on -device vfio-pci,host=01:00.1,id=hostdev1,bus=pcie.0
Sorry, I don't remember why the HDMI soundcard (01:00.1) is connected directly to pcie.0, but it works.
