48/** @defgroup grp_pdm_interfaces The PDM Interface Definitions
49 * @ingroup grp_pdm
50 *
51 * For historical reasons (the PDMINTERFACE enum) a lot of interface was stuffed
52 * together in this group instead, dragging stuff into global space that didn't
53 * need to be there and making this file huge (>2500 lines). Since we're using
54 * UUIDs as interface identifiers (IIDs) now, no only generic PDM interface will
55 * be added to this file. Component specific interface should be defined in the
56 * header file of that component.
57 *
58 * Interfaces consists of a method table (typedef'ed struct) and an interface
59 * ID. The typename of the method table should have an 'I' in it, be all
60 * capitals and according to the rules, no underscores. The interface ID is a
61 * \#define constructed by appending '_IID' to the typename. The IID value is a
62 * UUID string on the form "a2299c0d-b709-4551-aa5a-73f59ffbed74". If you stick
63 * to these rules, you can make use of the PDMIBASE_QUERY_INTERFACE and
64 * PDMIBASE_RETURN_INTERFACE when querying interface and implementing
65 * PDMIBASE::pfnQueryInterface respectively.
66 *
67 * In most interface descriptions the orientation of the interface is given as
68 * 'down' or 'up'. This refers to a model with the device on the top and the
69 * drivers stacked below it. Sometimes there is mention of 'main' or 'external'
70 * which normally means the same, i.e. the Main or VBoxBFE API. Picture the
71 * orientation of 'main' as horizontal.
