23/** @page pg_iom IOM - The Input/Output Monitor
24 *
25 * The input/output monitor will handle I/O exceptions routing them to the
26 * appropriate device. It implements an API to register and deregister
27 * virtual port I/O handler and memory mapped I/O handlers. A handler is
28 * PDM devices and a set of callback functions.
29 *
30 * Port I/O (PIO) is easily trapped by ensuring IOPL is 0, thus causing \#GP(0) on
31 * any access to I/O ports. Using the dissassembler (DIS) the faulting
32 * instruction will be interpreted determing the port and if there is a handler
33 * for it. If a handler exists it will be called, else default action will be
34 * performed.
35 *
36 * Memory Mapped I/O (MMIO) is gonna be worse since there are numerous instructions
37 * which can access memory. I'm afraid we might have to emulate each
38 * instruction which faults. The Execution Monitor (EM) will provide facilities
39 * for doing this using DIS.
40 *
41 * Emulating I/O port access is less complex and sligtly faster than emulating MMIO,
42 * so in most cases we should encourage the OS to use PIO. Devices which are freqently
43 * accessed should register GC handlers to speed up execution.
