3 * This file defines the trace event structures that go into the ring
4 * buffer directly. They are created via macros so that changes for them
5 * appear in the format file. Using macros will automate this process.
6 *
7 * The macro used to create a ftrace data structure is:
8 *
9 * FTRACE_ENTRY( name, struct_name, id, structure, print )
10 *
11 * @name: the name used the event name, as well as the name of
12 * the directory that holds the format file.
13 *
14 * @struct_name: the name of the structure that is created.
15 *
16 * @id: The event identifier that is used to detect what event
17 * this is from the ring buffer.
18 *
19 * @structure: the structure layout
20 *
21 * - __field( type, item )
22 * This is equivalent to declaring
23 * type item;
24 * in the structure.
25 * - __array( type, item, size )
26 * This is equivalent to declaring
27 * type item[size];
28 * in the structure.
29 *
30 * * for structures within structures, the format of the internal
31 * structure is laid out. This allows the internal structure
32 * to be deciphered for the format file. Although these macros
33 * may become out of sync with the internal structure, they
34 * will create a compile error if it happens. Since the
35 * internal structures are just tracing helpers, this is not
36 * an issue.
37 *
38 * When an internal structure is used, it should use:
39 *
40 * __field_struct( type, item )
41 *
42 * instead of __field. This will prevent it from being shown in
43 * the output file. The fields in the structure should use.
44 *
45 * __field_desc( type, container, item )
46 * __array_desc( type, container, item, len )
47 *
48 * type, item and len are the same as __field and __array, but
49 * container is added. This is the name of the item in
50 * __field_struct that this is describing.
51 *
52 *
53 * @print: the print format shown to users in the format file.
