Last change on this file since 31446 was 31395, checked in by vboxsync, 14 years ago

CPUM.cpp: Added /CPUM/EnableNX config option, defaults to false. Useful for raw-mode where we don't normally enable NXE.

19 *
20 * The CPU Monitor / Manager keeps track of all the CPU registers. It is
21 * also responsible for lazy FPU handling and some of the context loading
22 * in raw mode.
23 *
24 * There are three CPU contexts, the most important one is the guest one (GC).
25 * When running in raw-mode (RC) there is a special hyper context for the VMM
26 * part that floats around inside the guest address space. When running in
27 * raw-mode, CPUM also maintains a host context for saving and restoring
28 * registers accross world switches. This latter is done in cooperation with the
29 * world switcher (@see pg_vmm).
30 *
