qemu simulate xlnx-zcu102 report No 'PCI' bus found

Question

qemu version is 7.1.0
I use qemu to simulate xlnx-zcu102. my qemu command is below, it can run OK:
./qemu-system-aarch64 -M xlnx-zcu102 -smp 4 -m 4G ......

but, when I add -device virtio-gpu or -device virtio-gpu-device,
(I added only one device: virtio-gpu)
qemu tell me ERROR like this:
qemu-system-aarch64: -device virtio-gpu: No 'PCI' bus found for device 'virtio-gpu-pci'

I don't know how to add a virtio-gpu device to xlnx-zcu102 in qemu command.

Answer 1

You can't add that device to that machine type. The xlnx-zcu102 machine type simulates a piece of real hardware that does not have a PCI bus, and so you cannot plug PCI devices into it. You need to either use a different machine type, or else not use virtio devices.
