It is * also responsible for lazy FPU handling and some of the context loading * in raw mode. * * There are three CPU contexts, the most important one is the guest one (GC). * When running in raw-mode (RC) there is a special hyper context for the VMM * part that floats around inside the guest address space. When running in * raw-mode, CPUM also maintains a host context for saving and restoring * registers accross world switches. This latter is done in cooperation with the * world switcher (@see pg_vmm). * * @see grp_cpum */ /******************************************************************************* * Header Files * *******************************************************************************/ #define LOG_GROUP LOG_GROUP_CPUM #include #include #include #include #include #include #include #include #include #include #include "CPUMInternal.h" #include #include #include #include #include #include #include #include #include #include /******************************************************************************* * Defined Constants And Macros * *******************************************************************************/ /** The saved state version. */ #define CPUM_SAVED_STATE_VERSION 10 /** The saved state version for the 2.1 trunk before the MSR changes. */ #define CPUM_SAVED_STATE_VERSION_VER2_1_NOMSR 9 /** The saved state version of 2.0, used for backwards compatibility. */ #define CPUM_SAVED_STATE_VERSION_VER2_0 8 /** The saved state version of 1.6, used for backwards compatability. */ #define CPUM_SAVED_STATE_VERSION_VER1_6 6 /******************************************************************************* * Structures and Typedefs * *******************************************************************************/ /** * What kind of cpu info dump to perform. */ typedef enum CPUMDUMPTYPE { CPUMDUMPTYPE_TERSE, CPUMDUMPTYPE_DEFAULT, CPUMDUMPTYPE_VERBOSE } CPUMDUMPTYPE; /** Pointer to a cpu info dump type. */ typedef CPUMDUMPTYPE *PCPUMDUMPTYPE; /******************************************************************************* * Internal Functions * *******************************************************************************/ static int cpumR3CpuIdInit(PVM pVM); static DECLCALLBACK(int) cpumR3Save(PVM pVM, PSSMHANDLE pSSM); static DECLCALLBACK(int) cpumR3Load(PVM pVM, PSSMHANDLE pSSM, uint32_t u32Version); static DECLCALLBACK(void) cpumR3InfoAll(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) cpumR3InfoGuest(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) cpumR3InfoGuestInstr(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) cpumR3InfoHyper(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) cpumR3InfoHost(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); static DECLCALLBACK(void) cpumR3CpuIdInfo(PVM pVM, PCDBGFINFOHLP pHlp, const char *pszArgs); /** * Initializes the CPUM. * * @returns VBox status code. * @param pVM The VM to operate on. */ VMMR3DECL(int) CPUMR3Init(PVM pVM) { LogFlow(("CPUMR3Init\n")); /* * Assert alignment and sizes. */ AssertRelease(!(RT_OFFSETOF(VM, cpum.s) & 31)); AssertRelease(sizeof(pVM->cpum.s) <= sizeof(pVM->cpum.padding)); /* * Setup any fixed pointers and offsets. */ pVM->cpum.s.pHyperCoreR3 = CPUMCTX2CORE(&pVM->cpum.s.Hyper); pVM->cpum.s.pHyperCoreR0 = VM_R0_ADDR(pVM, CPUMCTX2CORE(&pVM->cpum.s.Hyper)); /* Hidden selector registers are invalid by default. */ pVM->cpum.s.fValidHiddenSelRegs = false; /* Calculate the offset from CPUM to CPUMCPU for the first CPU. */ pVM->cpum.s.ulOffCPUMCPU = RT_OFFSETOF(VM, aCpus[0].cpum) - RT_OFFSETOF(VM, cpum); Assert((uintptr_t)&pVM->cpum + pVM->cpum.s.ulOffCPUMCPU == (uintptr_t)&pVM->aCpus[0].cpum); /* Calculate the offset from CPUMCPU to CPUM. */ for (unsigned i=0;icCPUs;i++) { pVM->aCpus[i].cpum.s.ulOffCPUM = RT_OFFSETOF(VM, aCpus[i].cpum) - RT_OFFSETOF(VM, cpum); Assert((uintptr_t)&pVM->aCpus[i].cpum - pVM->aCpus[i].cpum.s.ulOffCPUM == (uintptr_t)&pVM->cpum); } /* * Check that the CPU supports the minimum features we require. */ if (!ASMHasCpuId()) { Log(("The CPU doesn't support CPUID!\n")); return VERR_UNSUPPORTED_CPU; } ASMCpuId_ECX_EDX(1, &pVM->cpum.s.CPUFeatures.ecx, &pVM->cpum.s.CPUFeatures.edx); ASMCpuId_ECX_EDX(0x80000001, &pVM->cpum.s.CPUFeaturesExt.ecx, &pVM->cpum.s.CPUFeaturesExt.edx); /* Setup the CR4 AND and OR masks used in the switcher */ /* Depends on the presence of FXSAVE(SSE) support on the host CPU */ if (!pVM->cpum.s.CPUFeatures.edx.u1FXSR) { Log(("The CPU doesn't support FXSAVE/FXRSTOR!\n")); /* No FXSAVE implies no SSE */ pVM->cpum.s.CR4.AndMask = X86_CR4_PVI | X86_CR4_VME; pVM->cpum.s.CR4.OrMask = 0; } else { pVM->cpum.s.CR4.AndMask = X86_CR4_OSXMMEEXCPT | X86_CR4_PVI | X86_CR4_VME; pVM->cpum.s.CR4.OrMask = X86_CR4_OSFSXR; } if (!pVM->cpum.s.CPUFeatures.edx.u1MMX) { Log(("The CPU doesn't support MMX!\n")); return VERR_UNSUPPORTED_CPU; } if (!pVM->cpum.s.CPUFeatures.edx.u1TSC) { Log(("The CPU doesn't support TSC!\n")); return VERR_UNSUPPORTED_CPU; } /* Bogus on AMD?
