If the emulated MMCONFIG approach will be modified to become
fully compatible with multiple ioreq servers (whatever they used for), I
assume there will be no objections that emulated MMCONFIG can't be
used?
I just want to clarify this moment -- why people think that
a completely emulated MMIO range, not related in any
way to host's MMCONFIG may compromise something.
