source: vbox/trunk/src/VBox/VMM/VMMR3/PDMDevMiscHlp.cpp@ 74795

Last change on this file since 74795 was 70948, checked in by vboxsync, 6 years ago

VMM: Added a bMainExecutionEngine member to the VM structure for use instead of fHMEnabled and fNEMEnabled. Changed a lot of HMIsEnabled invocations to use the new macros VM_IS_RAW_MODE_ENABLED and VM_IS_HM_OR_NEM_ENABLED. Eliminated fHMEnabledFixed. Fixed inverted test for raw-mode debug register sanity checking. Some other minor cleanups.
