22/** @page pg_cpum CPUM - CPU Monitor / Manager
23 *
24 * The CPU Monitor / Manager keeps track of all the CPU registers. It is
25 * also responsible for lazy FPU handling and some of the context loading
26 * in raw mode.
27 *
28 * There are three CPU contexts, the most important one is the guest one (GC).
29 * When running in raw-mode (RC) there is a special hyper context for the VMM
30 * part that floats around inside the guest address space. When running in
31 * raw-mode, CPUM also maintains a host context for saving and restoring
32 * registers accross world switches. This latter is done in cooperation with the
33 * world switcher (@see pg_vmm).
34 *
35 * @see grp_cpum
