It looks like zcore didn't map the BAR space for device(used to config device under pci)
If you look up query_or_map trait, you can see it's only implemented by arch riscv64.
So you will have a page fault in any other arch. Maybe you can write config to BAR space use physical address directly. Or implement query_or_map for x86 arch.
