Last change on this file since 73711 was 73606, checked in by vboxsync, 6 years ago

VMM: Nested VMX: bugref:9180 Various bits:

  • IEM: Started VMXON, VMXOFF implementation, use IEM_OPCODE_GET_NEXT_RM.
  • IEM: Fixed INVPCID C impl, removed unused IEMExecDecodedInvpcid.
  • IEM: Updated iemCImpl_load_CrX to check for CR0/CR4 fixed bits in VMX.
  • IEM: Update offModRm to reset/re-initialize where needed.
  • CPUM: Added VMX root, non-root mode and other bits and updated a few places where they're used.
  • HM: Started adding fine-grained VMX instruction failure diagnostics.
  • HM: Made VM instruction error an enum.
  • HM: Added HMVMXAll.cpp for all context VMX code.
  • Ensure building with VBOX_WITH_NESTED_HWVIRT_[SVM|VMX] does the right thing based on host CPU.
  • CPUM: Added dumping of nested-VMX CPUMCTX state.
  • HMVMXR0: Added memory operand decoding.
  • HMVMXR0: VMX instr. privilege checks (CR0/CR4 read shadows are not consulted, so we need to do them)
  • HM: Added some more bit-field representaions.
  • Recompiler: Refuse to run when in nested-VMX guest code.
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
