|
|---|
| 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 virtual
|
|---|
| 23 | * I/0 port handlers and memory mapped I/O handlers. A handler is PDM devices
|
|---|
| 24 | * and a set of callback functions.
|
|---|
| 25 | *
|
|---|
| 26 | * @see grp_iom
|
|---|
| 27 | *
|
|---|
| 28 | *
|
|---|
| 29 | * @section sec_iom_rawmode Raw-Mode
|
|---|
| 30 | *
|
|---|
| 31 | * In raw-mode I/O port access is trapped (\#GP(0)) by ensuring that the actual
|
|---|
| 32 | * IOPL is 0 regardless of what the guest IOPL is. The \#GP handler use the
|
|---|
| 33 | * dissassembler (DIS) to figure which instruction caused it (there are a number
|
|---|
| 34 | * of instructions in addition to the I/O ones) and if it's an I/O port access
|
|---|
| 35 | * it will hand it to IOMGCIOPortHandler (via EMInterpretPortIO).
|
|---|
| 36 | * IOMGCIOPortHandler will lookup the port in the AVL tree of registered
|
|---|
| 37 | * handlers. If found, the handler will be called otherwise default action is
|
|---|
| 38 | * taken. (Default action is to write into the void and read all set bits.)
|
|---|
| 39 | *
|
|---|
| 40 | * Memory Mapped I/O (MMIO) is implemented as a sligtly special case of PGM
|
|---|
| 41 | * access handlers. An MMIO range is registered with IOM which then registers it
|
|---|
| 42 | * with the PGM access handler sub-system. The access handler catches all
|
|---|
| 43 | * access and will be called in the context of a \#PF handler. In RC and R0 this
|
|---|
| 44 | * handler is IOMMMIOHandler while in ring-3 it's IOMR3MMIOHandler (althought in
|
|---|
| 45 | * ring-3 there can be alternative ways). IOMMMIOHandler will attempt to emulate
|
|---|
| 46 | * the instruction that is doing the access and pass the corresponding reads /
|
|---|
| 47 | * writes to the device.
|
|---|
| 48 | *
|
|---|
| 49 | * Emulating I/O port access is less complex and should be sligtly faster than
|
|---|
| 50 | * emulating MMIO, so in most cases we should encourage the OS to use port I/O.
|
|---|
| 51 | * Devices which are freqently accessed should register GC handlers to speed up
|
|---|
| 52 | * execution.
|
|---|

|
|---|
| 55 | * @section sec_iom_hwaccm Hardware Assisted Virtualization Mode
|
|---|
| 56 | *
|
|---|
| 57 | * When running in hardware assisted virtualization mode we'll be doing much the
|
|---|
| 58 | * same things as in raw-mode. The main difference is that we're running in the
|
|---|
| 59 | * host ring-0 context and that we don't get faults (\#GP(0) and \#PG) but
|
|---|
| 60 | * exits.
|
|---|
| 61 | *
|
|---|
| 62 | *
|
|---|
| 63 | * @section sec_iom_rem Recompiled Execution Mode
|
|---|
| 64 | *
|
|---|
| 65 | * When running in the recompiler things are different. I/O port access is
|
|---|
| 66 | * handled by calling IOMIOPortRead and IOMIOPortWrite directly. While MMIO can
|
|---|
| 67 | * be handled in one of two ways. The normal way is that we have a registered a
|
|---|
| 68 | * special RAM range with the recompiler and in the three callbacks (for byte,
|
|---|
| 69 | * word and dword access) we call IOMMMIORead and IOMMMIOWrite directly. The
|
|---|
| 70 | * alternative ways that the physical memory access which goes via PGM will take
|
|---|
| 71 | * care of it by calling IOMR3MMIOHandler via the PGM access handler machinery
|
|---|
| 72 | * - this shouldn't happen but it is an alternative...
|
|---|
| 73 | *
|
|---|
| 74 | *
|
|---|
| 75 | * @section sec_iom_other Other Accesses
|
|---|
| 76 | *
|
|---|
| 77 | * I/O ports aren't really exposed in any other way, unless you count the
|
|---|
| 78 | * instruction interpreter in EM, but that's just what we're doing in the
|
|---|
| 79 | * raw-mode \#GP(0) case really. Now it's possible to call IOMIOPortRead and
|
|---|
| 80 | * IOMIOPortWrite directly to talk to a device, but this is really bad behavior
|
|---|
| 81 | * and should only be done as temporary hacks (the PC BIOS device used to
|
|---|
| 82 | * setup the CMOS this way back in the dark ages).
|
|---|
| 83 | *
|
|---|
| 84 | * MMIO has similar direct routes as the I/O ports and these shouldn't be used
|
|---|
| 85 | * for the same reasons and with the same restrictions. OTOH since MMIO is
|
|---|
| 86 | * mapped into the physical memory address space, it can be accessed in a number
|
|---|
| 87 | * of ways thru PGM.
