22/** @page pg_cpum
23 * The CPU Monitor / Manager keeps track of all the CPU registers. It is
24 * also responsible for lazy FPU handling and some of the context loading
25 * in raw mode.
26 *
27 * There are three CPU contexts, the most important one is the guest one (GC).
28 * When running in raw-mode (RC) there is a special hyper context for the VMM
29 * that floats around inside the guest address space. When running in raw-mode
30 * or when using 64-bit guests on a 32-bit host, CPUM also maintains a host
31 * context for saving and restoring registers accross world switches. This latter
32 * is done in cooperation with the world switcher (@see pg_vmm).
