--- Comment #34 from Wei Hu <weh@microsoft.com> ---
(In reply to Dexuan Cui from comment #33)
It might be hard to tell which mmio space is bad for other PCI devices and =
how
big the size it could be after user changes it according to the link. It co=
uld
be always fixed at 0xf8000000 or starting from the beginning of the mmio sp=
ace
under 4GB. Unfortunately we don't have a good test environment to verify.=20

For the time being I think we can temporarily accept this fixed address and
size after it has been verified in Dmitry's env. We can change it later if =
new
cases emerge on which we can verify. What do you think?
