Thank you for your reply.
I'm sorry, I don't know much about Solaris device path.
My device path doesn't use bus# but ACPI's _HID, _UID, device# and
function#. Therefore, even if a new device is added, device path
remains unchanged. For your reference, I attached our example figure.
My device path is similar to EFI's one. So my RFC suits fine on x86 and
IA64 architecture.
My RFC keeps current Xen's SBDF assignment. So you can add Solaris
device path if you need to do.
Thanks,
