in same iommu group. In below example config, guest virtio-iommu driver
can successfully probe first device but fail on others. Only one device
under the bridge can work normally.
-device virtio-iommu \
-device pcie-pci-bridge,
This adds PCI device's real bus and devfn to API get_address_space(),
for vIOMMU which also wants real BDF, i.e., virtio-iommu.

Have a look at decode_opc() in target/riscv/translate.c.

Do you mind including a pointer to the exact spec (a Github link with
the SHA or tag is great) that you are targeting? We are having issues
with a different spec, so it will be helpful in future to know exactly

The current article is not extremely easy to follow, and may contain too
much information for someone looking for solutions on VMSD compatibility
