/** @page pg_iom IOM - The Input / Output Monitor
*
* appropriate device. It implements an API to register and deregister
* virtual port I/O handler and memory mapped I/O handlers. A handler is
* PDM devices and a set of callback functions.
*
* Port I/O (PIO) is easily trapped by ensuring IOPL is 0, thus causing \#GP(0) on
* any access to I/O ports. Using the dissassembler (DIS) the faulting
* instruction will be interpreted determing the port and if there is a handler
* for it. If a handler exists it will be called, else default action will be
* performed.
*
* Memory Mapped I/O (MMIO) is gonna be worse since there are numerous instructions
* which can access memory. I'm afraid we might have to emulate each
* instruction which faults. The Execution Monitor (EM) will provide facilities
* for doing this using DIS.
*
* Emulating I/O port access is less complex and sligtly faster than emulating MMIO,
* so in most cases we should encourage the OS to use PIO. Devices which are freqently
* accessed should register GC handlers to speed up execution.
