18/** @page pg_cfgm CFGM - The Configuration Manager
19 *
20 * The configuration manager is a directory containing the VM configuration at
21 * run time. It works in a manner similar to the windows registry - it's like a
22 * file system hierarchy, but the files (values) live in a separate name space
23 * and can include the path separators.
24 *
25 * The configuration is normally created via a callback passed to VMR3Create()
26 * via the pfnCFGMConstructor parameter. To make testcase writing a bit simpler,
27 * we allow the callback to be NULL, in which case a simple default
28 * configuration will be created by CFGMR3ConstructDefaultTree(). The
29 * Console::configConstructor() method in Main/ConsoleImpl2.cpp creates the
30 * configuration from the XML.
31 *
32 * Devices, drivers, services and other PDM stuff are given their own subtree
33 * where they are protected from accessing information of any parents. This is
34 * is implemented via the CFGMR3SetRestrictedRoot() API.
35 *
36 * Data validation beyond the basic primitives is left to the caller. The caller
37 * is in a better position to know the proper validation rules of the individual
38 * properties.
39 *
40 * @see grp_cfgm
41 *
42 *
43 * @section sec_cfgm_primitives Data Primitives
44 *
45 * CFGM supports the following data primitives:
46 * - Integers. Representation is unsigned 64-bit. Boolean, unsigned and
47 * small integers, and pointers are all represented using this primitive.
48 * - Zero terminated character strings. These are of course UTF-8.
49 * - Variable length byte strings. This can be used to get/put binary
50 * objects like for instance RTMAC.
