It's correct that xen VMM doesn't fully understand io area.
However the VMM know all about RAM.
Thanks for your explanation, see my comment.
So far !mfn_valid() has sufficed for the current implementation

In x86 side, only it is identity mapping, guest can access the port
directly.
If it is not identity mapping, guest can not access the port
directly, at this situation, xen will intercept io port access
first, and xen access the corresponding physical port.
In ia64
use VTD to assing device, guest port may not be equal to host port.

Hi isaku,
If I remembered correctly, last time I encountered issue at line page =
mfn_to_page(mfn);
Page returns 0.
I suspect if page_info for IOPORTs is initialized.
Any idea?
Thanks,
Anthony

Which line do you have trouble?
Do you mean that mfn_to_page(mfn) returned NULL?
