HM.cpp@ 86087

Last change on this file since 86087 was 85854, checked in by vboxsync, 4 years ago
VMM/HM: Don't need to store fAllowNestedPaging and fAllowUnrestricted (both are unused outside the HM.cpp) in the VM or VMCPU struct. Makes room for future bools in their place.
Property svn:eol-style set to `native` Property svn:keywords set to `Id Revision`

19	*
20	* The HM manages guest execution using the VT-x and AMD-V CPU hardware
21	* extensions.
22	*
23	* {summary of what HM does}
24	*
25	* Hardware assisted virtualization manager was originally abbreviated HWACCM,
26	* however that was cumbersome to write and parse for such a central component,
27	* so it was shortened to HM when refactoring the code in the 4.3 development
28	* cycle.
29	*
30	* {add sections with more details}
