- The User-Mode Linux port can provide support for IO Memory
- emulation with this option. This allows a host file to be
- specified as an I/O region on the kernel command line. That file
- will be mapped into UML's kernel address space where a driver can
- locate it and do whatever it wants with the memory, including
- providing an interface to it for UML processes to use.

- If you'd like to be able to provide a simulated IO port space for
- User-Mode Linux processes, say Y. If unsure, say N.
