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 virtual
27 * I/0 port handlers and memory mapped I/O handlers. A handler is PDM devices
28 * and a set of callback functions.
29 *
30 * @see grp_iom
31 *
32 *
33 * @section sec_iom_rawmode Raw-Mode
34 *
35 * In raw-mode I/O port access is trapped (\#GP(0)) by ensuring that the actual
36 * IOPL is 0 regardless of what the guest IOPL is. The \#GP handler use the
37 * dissassembler (DIS) to figure which instruction caused it (there are a number
38 * of instructions in addition to the I/O ones) and if it's an I/O port access
39 * it will hand it to IOMGCIOPortHandler (via EMInterpretPortIO).
40 * IOMGCIOPortHandler will lookup the port in the AVL tree of registered
41 * handlers. If found, the handler will be called otherwise default action is
42 * taken. (Default action is to write into the void and read all set bits.)
43 *
44 * Memory Mapped I/O (MMIO) is implemented as a sligtly special case of PGM
45 * access handlers. An MMIO range is registered with IOM which then registers it
46 * with the PGM access handler sub-system. The access handler catches all
47 * access and will be called in the context of a \#PF handler. In RC and R0 this
48 * handler is IOMMMIOHandler while in ring-3 it's IOMR3MMIOHandler (althought in
49 * ring-3 there can be alternative ways). IOMMMIOHandler will attempt to emulate
50 * the instruction that is doing the access and pass the corresponding reads /
51 * writes to the device.
52 *
53 * Emulating I/O port access is less complex and should be sligtly faster than
54 * emulating MMIO, so in most cases we should encourage the OS to use port I/O.
55 * Devices which are freqently accessed should register GC handlers to speed up
56 * execution.
57 *
58 *
59 * @section sec_iom_hwaccm Hardware Assisted Virtualization Mode
60 *
61 * When running in hardware assisted virtualization mode we'll be doing much the
62 * same things as in raw-mode. The main difference is that we're running in the
63 * host ring-0 context and that we don't get faults (\#GP(0) and \#PG) but
64 * exits.
65 *
66 *
67 * @section sec_iom_rem Recompiled Execution Mode
68 *
69 * When running in the recompiler things are different. I/O port access is
70 * handled by calling IOMIOPortRead and IOMIOPortWrite directly. While MMIO can
71 * be handled in one of two ways. The normal way is that we have a registered a
72 * special RAM range with the recompiler and in the three callbacks (for byte,
73 * word and dword access) we call IOMMMIORead and IOMMMIOWrite directly. The
74 * alternative ways that the physical memory access which goes via PGM will take
75 * care of it by calling IOMR3MMIOHandler via the PGM access handler machinery
76 * - this shouldn't happen but it is an alternative...
77 *
78 *
79 * @section sec_iom_other Other Accesses
80 *
81 * I/O ports aren't really exposed in any other way, unless you count the
82 * instruction interpreter in EM, but that's just what we're doing in the
83 * raw-mode \#GP(0) case really. Now it's possible to call IOMIOPortRead and
84 * IOMIOPortWrite directly to talk to a device, but this is really bad behavior
85 * and should only be done as temporary hacks (the PC BIOS device used to
86 * setup the CMOS this way back in the dark ages).
87 *
88 * MMIO has similar direct routes as the I/O ports and these shouldn't be used
89 * for the same reasons and with the same restrictions. OTOH since MMIO is
90 * mapped into the physical memory address space, it can be accessed in a number
91 * of ways thru PGM.
