PDMDriver.cpp@ 72687

最後變更在這個檔案從72687是 70948,由 vboxsync 提交於 7 年前
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.
