Maybe I lost something. But why here is 0xC0000-0xDFFFF? I think
your patch marks 0xC0000000 ~ 0xDFFFFFFF as system memory is pretty right for
MMIO space.
With your patch, I didn't see any graphic issue, it works fine
on my box. Now I can successful install sample driver of WDK in my windows
guest(pls see attachment). Unfortunately, after send some packets out, dom0
crash and output below info(sometimes it lead to a windows blue screen). I am
still
on the way :(
