2 * Stage 1 of the trace events.
4 * Override the macros in <trace/trace_events.h> to include the following:
6 * struct ftrace_raw_<call> {
7 * struct trace_entry ent;
8 * <type> <item>;
9 * <type2> <item2>[<len>];
10 * [...]
11 * };
13 * The <type> <item> is created by the __field(type, item) macro or
14 * the __array(type2, item2, len) macro.
15 * We simply do "type item;", and that will create the fields
16 * in the structure.
19 #include <linux/ftrace_event.h>
22 * DECLARE_EVENT_CLASS can be used to add a generic function
23 * handlers for events. That is, if all events have the same
24 * parameters and just have distinct trace points.
25 * Each tracepoint can be defined with DEFINE_EVENT and that
26 * will map the DECLARE_EVENT_CLASS to the tracepoint.
28 * TRACE_EVENT is a one to one mapping between tracepoint and template.
