2 | * This file defines the trace event structures that go into the ring | |
3 | * buffer directly. They are created via macros so that changes for them | |
4 | * appear in the format file. Using macros will automate this process. | |
5 | * | |
6 | * The macro used to create a ftrace data structure is: | |
7 | * | |
8 | * FTRACE_ENTRY( name, struct_name, id, structure, print ) | |
9 | * | |
10 | * @name: the name used the event name, as well as the name of | |
11 | * the directory that holds the format file. | |
12 | * | |
13 | * @struct_name: the name of the structure that is created. | |
14 | * | |
15 | * @id: The event identifier that is used to detect what event | |
16 | * this is from the ring buffer. | |
17 | * | |
18 | * @structure: the structure layout | |
19 | * | |
20 | * - __field( type, item ) | |
21 | * This is equivalent to declaring | |
22 | * type item; | |
23 | * in the structure. | |
24 | * - __array( type, item, size ) | |
25 | * This is equivalent to declaring | |
26 | * type item[size]; | |
27 | * in the structure. | |
28 | * | |
29 | * @print: the print format shown to users in the format file. | |
