IMNSHO I think you can default to 8 digits for I/O for PCI, since at least last I looked there was no 64-bit address space possible for I/O.
Resources are representing different things on different platforms.
On sparc64 it's actually the full 64-bit physical I/O address on the
system bus being stored in there. So even IORESOURCE_IO objects have
64-bits of relevancy.
And then it should be printed as such on that platform.
Like I said, printing out the entire thing has helped me find real
bugs, so printing the whole thing is not without merit.
No argument there. I was referring only to platforms where the resource
contains a PCI I/O address, which is 32 bits long unless limited by
additional constraints (like x86's 16-bit limit.)
