It implements an API to register and deregister virtual * I/0 port handlers and memory mapped I/O handlers. A handler is PDM devices * and a set of callback functions. * * @see grp_iom * * * @section sec_iom_rawmode Raw-Mode * * In raw-mode I/O port access is trapped (\#GP(0)) by ensuring that the actual * IOPL is 0 regardless of what the guest IOPL is. The \#GP handler use the * disassembler (DIS) to figure which instruction caused it (there are a number * of instructions in addition to the I/O ones) and if it's an I/O port access * it will hand it to IOMRCIOPortHandler (via EMInterpretPortIO). * IOMRCIOPortHandler will lookup the port in the AVL tree of registered * handlers. If found, the handler will be called otherwise default action is * taken. (Default action is to write into the void and read all set bits.) * * Memory Mapped I/O (MMIO) is implemented as a slightly special case of PGM * access handlers. An MMIO range is registered with IOM which then registers it * with the PGM access handler sub-system. The access handler catches all * access and will be called in the context of a \#PF handler. In RC and R0 this * handler is iomMmioPfHandler while in ring-3 it's iomR3MmioHandler (although * in ring-3 there can be alternative ways). iomMmioPfHandler will attempt to * emulate the instruction that is doing the access and pass the corresponding * reads / writes to the device. * * Emulating I/O port access is less complex and should be slightly faster than * emulating MMIO, so in most cases we should encourage the OS to use port I/O. * Devices which are frequently accessed should register GC handlers to speed up * execution. * * * @section sec_iom_hm Hardware Assisted Virtualization Mode * * When running in hardware assisted virtualization mode we'll be doing much the * same things as in raw-mode. The main difference is that we're running in the * host ring-0 context and that we don't get faults (\#GP(0) and \#PG) but * exits. * * * @section sec_iom_rem Recompiled Execution Mode * * When running in the recompiler things are different. I/O port access is * handled by calling IOMIOPortRead and IOMIOPortWrite directly. While MMIO can * be handled in one of two ways. The normal way is that we have a registered a * special RAM range with the recompiler and in the three callbacks (for byte, * word and dword access) we call IOMMMIORead and IOMMMIOWrite directly. The * alternative ways that the physical memory access which goes via PGM will take * care of it by calling iomR3MmioHandler via the PGM access handler machinery * - this shouldn't happen but it is an alternative... * * * @section sec_iom_other Other Accesses * * I/O ports aren't really exposed in any other way, unless you count the * instruction interpreter in EM, but that's just what we're doing in the * raw-mode \#GP(0) case really. Now, it's possible to call IOMIOPortRead and * IOMIOPortWrite directly to talk to a device, but this is really bad behavior * and should only be done as temporary hacks (the PC BIOS device used to setup * the CMOS this way back in the dark ages). * * MMIO has similar direct routes as the I/O ports and these shouldn't be used * for the same reasons and with the same restrictions. OTOH since MMIO is * mapped into the physical memory address space, it can be accessed in a number * of ways thru PGM. * * * @section sec_iom_logging Logging Levels * * Following assignments: * - Level 5 is used for defering I/O port and MMIO writes to ring-3. * */ /** @todo MMIO - simplifying the device end. * - Add a return status for doing DBGFSTOP on access where there are no known * registers. * - * * */ /********************************************************************************************************************************* * Header Files * *********************************************************************************************************************************/ #define LOG_GROUP LOG_GROUP_IOM #include #include #include #include #include #include #include #include #include #include #include "IOMInternal.h" #include #include #include #include #include #include #include #include "IOMInline.h" /********************************************************************************************************************************* * Internal Functions * *********************************************************************************************************************************/ static void iomR3FlushCache(PVM pVM); static DECLCALLBACK(int) iomR3RelocateIOPortCallback(PAVLROIOPORTNODECORE pNode, void *pvUser); static DECLCALLBACK(int) iomR3RelocateMMIOCallback(PAVLROGCPHYSNODECORE pNode, void *pvUser); static DECLCALLBACK(void) iomR3IOPortInfo(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) iomR3MMIOInfo(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static FNIOMIOPORTIN iomR3IOPortDummyIn; static FNIOMIOPORTOUT iomR3IOPortDummyOut; static FNIOMIOPORTINSTRING iomR3IOPortDummyInStr; static FNIOMIOPORTOUTSTRING iomR3IOPortDummyOutStr; #ifdef VBOX_WITH_STATISTICS static const char *iomR3IOPortGetStandardName(RTIOPORT Port); #endif /** * Initializes the IOM. * * @returns VBox status code. * @param pVM The cross context VM structure. */ VMMR3_INT_DECL(int) IOMR3Init(PVM pVM) { LogFlow(("IOMR3Init:\n")); /* * Assert alignment and sizes. */ AssertCompileMemberAlignment(VM, iom.s, 32); AssertCompile(sizeof(pVM->iom.s) <= sizeof(pVM->iom.padding)); AssertCompileMemberAlignment(IOM, CritSect, sizeof(uintptr_t)); /* * Setup any fixed pointers and offsets. */ pVM->iom.s.offVM = RT_OFFSETOF(VM, iom); /* * Initialize the REM critical section. */ #ifdef IOM_WITH_CRIT_SECT_RW int rc = PDMR3CritSectRwInit(pVM, &pVM->iom.s.CritSect, RT_SRC_POS, "IOM Lock"); #else int rc = PDMR3CritSectInit(pVM, &pVM->iom.s.CritSect, RT_SRC_POS, "IOM Lock"); #endif AssertRCReturn(rc, rc); /* * Allocate the trees structure. */ rc = MMHyperAlloc(pVM, sizeof(*pVM->iom.s.pTreesR3), 0, MM_TAG_IOM, (void **)&pVM->iom.s.pTreesR3); if (RT_SUCCESS(rc)) { pVM->iom.s.pTreesRC = MMHyperR3ToRC(pVM, pVM->iom.s.pTreesR3); pVM->iom.s.pTreesR0 = MMHyperR3ToR0(pVM, pVM->iom.s.pTreesR3); /* * Register the MMIO access handler type. */ rc = PGMR3HandlerPhysicalTypeRegister(pVM, PGMPHYSHANDLERKIND_MMIO, iomMmioHandler, NULL, "iomMmioHandler", "iomMmioPfHandler", NULL, "iomMmioHandler", "iomMmioPfHandler", "MMIO", &pVM->iom.s.hMmioHandlerType); AssertRC(rc); if (RT_SUCCESS(rc)) { /* * Info. */ DBGFR3InfoRegisterInternal(pVM, "ioport", "Dumps all IOPort ranges.
