|
---|
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.
