If all domains share the same I/O space, you should only map it once of course. > I was getting a warning from resource.c > > Btw, when I tested the io ranges before, kernel didn't accept anything > below 1k like 0. That is why my range starts at 1k. This is PCIBIOS_MIN_IO, it defines what I/O port numbers can be dynamically assigned to PCI devices, but you should still map the entire 64K area per domain, including the first 4K that can be used for legacy ISA compatibility.
