No, it's just something based on what you linked. Here's what I have: qemu-system-aarch64 -machine virt -cpu cortex-a72 -machine type=virt -nographic -smp 1 -m 2048 -kernel ../linux.git/arch/arm64/boot/Image --append console=ttyAMA0 -device pcie-root-port,port=0x10,chassis=9,id=pci.9,bus=pcie.0,multifunction=on,addr=0x3 -device pcie-root-port,port=0x11,chassis=10,id=pci.10,bus=pcie.0,addr=0x3.0x1 -device x3130-upstream,id=pci.11,bus=pci.9,addr=0x0 -device xio3130-downstream,port=0x0,chassis=11,id=pci.12,bus=pci.11,multifunction=on,addr=0x0 -device i82801b11-bridge,id=pci.13,bus=pcie.0,addr=0x4 -device pci-bridge,chassis_nr=14,id=pci.14,bus=pci.13,addr=0x0 -device pci-testdev,bus=pci.12,addr=0x0 Of course, you'll need a few changes to use ACPI.
