|
---|
23 | *
|
---|
24 | * The configuration manager is a directory containing the VM configuration at
|
---|
25 | * run time. It works in a manner similar to the windows registry - it's like a
|
---|
26 | * file system hierarchy, but the files (values) live in a separate name space
|
---|
27 | * and can include the path separators.
|
---|
28 | *
|
---|
29 | * The configuration is normally created via a callback passed to VMR3Create()
|
---|
30 | * via the pfnCFGMConstructor parameter. To make testcase writing a bit simpler,
|
---|
31 | * we allow the callback to be NULL, in which case a simple default
|
---|
32 | * configuration will be created by cfgmR3CreateDefaultTree(). The
|
---|
33 | * Console::configConstructor() method in Main/ConsoleImpl2.cpp creates the
|
---|
34 | * configuration from the XML.
|
---|
35 | *
|
---|
36 | * Devices, drivers, services and other PDM stuff are given their own subtree
|
---|
37 | * where they are protected from accessing information of any parents. This is
|
---|
38 | * is implemented via the CFGMR3SetRestrictedRoot() API.
|
---|
39 | *
|
---|
40 | * Data validation out over the basic primitives is left to the caller. The
|
---|
41 | * caller is in a better position to know the proper validation rules of the
|
---|
42 | * individual properties.

|
---|
48 | *
|
---|
49 | * CFGM supports the following data primitives:
|
---|
50 | * - Integers. Representation is unsigned 64-bit. Boolean, unsigned and
|
---|
51 | * small integers, and pointers are all represented using this primitive.
|
---|
52 | * - Zero terminated character strings. These are of course UTF-8.
|
---|
53 | * - Variable length byte strings. This can be used to get/put binary
|
---|
54 | * objects like for instance RTMAC.
