Last change on this file since 7802 was 7752, checked in by vboxsync, 17 years ago

Dropped the pszDesc argument to *MMIORegisterGC/R0. It only persists in the PDMDEVHLP interface now because of binary compatability.

19/** @page pg_iom IOM - The Input/Output Monitor
20 *
21 * The input/output monitor will handle I/O exceptions routing them to the
22 * appropriate device. It implements an API to register and deregister
23 * virtual port I/O handler and memory mapped I/O handlers. A handler is
24 * PDM devices and a set of callback functions.
25 *
26 * Port I/O (PIO) is easily trapped by ensuring IOPL is 0, thus causing \#GP(0) on
27 * any access to I/O ports. Using the dissassembler (DIS) the faulting
28 * instruction will be interpreted determing the port and if there is a handler
29 * for it. If a handler exists it will be called, else default action will be
30 * performed.
31 *
32 * Memory Mapped I/O (MMIO) is gonna be worse since there are numerous instructions
33 * which can access memory. I'm afraid we might have to emulate each
34 * instruction which faults. The Execution Monitor (EM) will provide facilities
35 * for doing this using DIS.
36 *
37 * Emulating I/O port access is less complex and sligtly faster than emulating MMIO,
38 * so in most cases we should encourage the OS to use PIO. Devices which are freqently
39 * accessed should register GC handlers to speed up execution.
