I don't think my patch is needed then. SMBIOS ways is fine for static configs where no hot-plug is involved. Also potentially SMBIOS way may be used by arm/virt board, since acpi-index shares a lot with ACPI PCI hotplug infrastructure and we haven't ported that to arm/virt impl. yet. It also won't work for Q35 at the moment, but Julia is working on adding support for ACPI PCI hotplug to it, and once it arrives acpi-index will become available there. Perhaps we should also add support for ACPI PCI hotplug to virt/arm, along with Q35.
