When talking about paging HC can also be refered to * as "host paging", and GC refered to as "shadow paging". * * We define three basic paging modes: 32-bit, PAE and AMD64. The host paging mode * is defined by the host operating system. The mode used in the shadow paging mode * depends on the host paging mode and what the mode the guest is currently in. The * following relation between the two is defined: * * @verbatim Host > 32-bit | PAE | AMD64 | Guest | | | | ==v================================ 32-bit 32-bit PAE PAE -------|--------|--------|--------| PAE PAE PAE PAE -------|--------|--------|--------| AMD64 AMD64 AMD64 AMD64 -------|--------|--------|--------| @endverbatim * * All configuration except those in the diagonal (upper left) are expected to * require special effort from the switcher (i.e. a bit slower). * * * * * @section sec_pg_shw The Shadow Memory Context * * * [..] * * Because of guest context mappings requires PDPTR and PML4 entries to allow * writing on AMD64, the two upper levels will have fixed flags whatever the * guest is thinking of using there. So, when shadowing the PD level we will * calculate the effective flags of PD and all the higher levels. In legacy * PAE mode this only applies to the PWT and PCD bits (the rest are * ignored/reserved/MBZ). We will ignore those bits for the present. * * * * @section sec_pg_int The Intermediate Memory Context * * The world switch goes thru an intermediate memory context which purpose it is * to provide different mappings of the switcher code. All guest mappings are also * present in this context. * * The switcher code is mapped at the same location as on the host, at an * identity mapped location (physical equals virtual address), and at the * hypervisor location. * * PGM maintain page tables for 32-bit, PAE and AMD64 paging modes. This * simplifies switching guest CPU mode and consistency at the cost of more * code to do the work. All memory use for those page tables is located below * 4GB (this includes page tables for guest context mappings). * * * @subsection subsec_pg_int_gc Guest Context Mappings * * During assignment and relocation of a guest context mapping the intermediate * memory context is used to verify the new location. * * Guest context mappings are currently restricted to below 4GB, for reasons * of simplicity. This may change when we implement AMD64 support. * * * * * @section sec_pg_misc Misc * * @subsection subsec_pg_misc_diff Differences Between Legacy PAE and Long Mode PAE * * The differences between legacy PAE and long mode PAE are: * -# PDPE bits 1, 2, 5 and 6 are defined differently. In leagcy mode they are * all marked down as must-be-zero, while in long mode 1, 2 and 5 have the * usual meanings while 6 is ignored (AMD). This means that upon switching to * legacy PAE mode we'll have to clear these bits and when going to long mode * they must be set. This applies to both intermediate and shadow contexts, * however we don't need to do it for the intermediate one since we're * executing with CR0.WP at that time. * -# CR3 allows a 32-byte aligned address in legacy mode, while in long mode * a page aligned one is required. */ /** Saved state data unit version. */ #define PGM_SAVED_STATE_VERSION 5 /******************************************************************************* * Header Files * *******************************************************************************/ #define LOG_GROUP LOG_GROUP_PGM #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include "PGMInternal.h" #include #include #include #include #include #include #include #include #include #include #include /******************************************************************************* * Internal Functions * *******************************************************************************/ static int pgmR3InitPaging(PVM pVM); static DECLCALLBACK(void) pgmR3PhysInfo(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) pgmR3InfoMode(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) pgmR3InfoCr3(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(int) pgmR3RelocatePhysHandler(PAVLROGCPHYSNODECORE pNode, void *pvUser); static DECLCALLBACK(int) pgmR3RelocateVirtHandler(PAVLROGCPTRNODECORE pNode, void *pvUser); static DECLCALLBACK(int) pgmR3Save(PVM pVM, PSSMHANDLE pSSM); static DECLCALLBACK(int) pgmR3Load(PVM pVM, PSSMHANDLE pSSM, uint32_t u32Version); static int pgmR3ModeDataInit(PVM pVM, bool fResolveGCAndR0); static void pgmR3ModeDataSwitch(PVM pVM, PGMMODE enmShw, PGMMODE enmGst); static PGMMODE pgmR3CalcShadowMode(PGMMODE enmGuestMode, SUPPAGINGMODE enmHostMode, PGMMODE enmShadowMode, VMMSWITCHER *penmSwitcher); #ifdef VBOX_WITH_STATISTICS static void pgmR3InitStats(PVM pVM); #endif #ifdef VBOX_WITH_DEBUGGER /** @todo all but the two last commands must be converted to 'info'. */ static DECLCALLBACK(int) pgmR3CmdRam(PCDBGCCMD pCmd, PDBGCCMDHLP pCmdHlp, PVM pVM, PCDBGCVAR paArgs, unsigned cArgs, PDBGCVAR pResult); static DECLCALLBACK(int) pgmR3CmdMap(PCDBGCCMD pCmd, PDBGCCMDHLP pCmdHlp, PVM pVM, PCDBGCVAR paArgs, unsigned cArgs, PDBGCVAR pResult); static DECLCALLBACK(int) pgmR3CmdSync(PCDBGCCMD pCmd, PDBGCCMDHLP pCmdHlp, PVM pVM, PCDBGCVAR paArgs, unsigned cArgs, PDBGCVAR pResult); static DECLCALLBACK(int) pgmR3CmdSyncAlways(PCDBGCCMD pCmd, PDBGCCMDHLP pCmdHlp, PVM pVM, PCDBGCVAR paArgs, unsigned cArgs, PDBGCVAR pResult); #endif /******************************************************************************* * Global Variables * *******************************************************************************/ #ifdef VBOX_WITH_DEBUGGER /** Command descriptors. */ static const DBGCCMD g_aCmds[] = { /* pszCmd, cArgsMin, cArgsMax, paArgDesc, cArgDescs, pResultDesc, fFlags, pfnHandler pszSyntax, ....pszDescription */ { "pgmram", 0, 0, NULL, 0, NULL, 0, pgmR3CmdRam, "", "Display the ram ranges." }, { "pgmmap", 0, 0, NULL, 0, NULL, 0, pgmR3CmdMap, "", "Display the mapping ranges." }, { "pgmsync", 0, 0, NULL, 0, NULL, 0, pgmR3CmdSync, "", "Sync the CR3 page." }, { "pgmsyncalways", 0, 0, NULL, 0, NULL, 0, pgmR3CmdSyncAlways, "", "Toggle permanent CR3 syncing." }, }; #endif #if 1/// @todo ndef __AMD64__ /* * Shadow -
