I just did some more testing with the oldish GPU I have for that
purpose. Seems to work, at least I get video output that keeps
on working - did not try advanced things yet.
I use
-device vfio-pci,host=05:00.0,x-vga=on
-device vfio-pci,host=05:00.1
when adding "-device intel-iommu", I got
"qemu-system-x86_64: -device vfio-pci,host=05:00.1: vfio 0000:05:00.1: group 23 used in multiple address spaces"
... so I poked around the internet a bit and got it running with
-device intel-iommu,caching-mode=on \
-device pcie-pci-bridge,addr=1e.0,id=pci.1 \
-device vfio-pci,host=05:00.0,xvga=on,bus=pci.1,addr=1.0,multifunction=on \
-device vfio-pci,host=05:00.1,bus=pci.1,addr=1.1 \
Things still seem to be working, so I assume it works
(I guess ?!).
