| 20 | * Trace files that want to automate creationg of all tracepoints defined | |
| 21 | * in their file should include this file. The following are macros that the | |
| 22 | * trace file may define: | |
| 23 | * | |
| 24 | * TRACE_SYSTEM defines the system the tracepoint is for | |
| 25 | * | |
| 26 | * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h | |
| 27 | * This macro may be defined to tell define_trace.h what file to include. | |
| 28 | * Note, leave off the ".h". | |
| 29 | * | |
| 30 | * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace | |
| 31 | * then this macro can define the path to use. Note, the path is relative to | |
| 3c82ede9 | 32 | * tracepoint_event.h, not the file including it. Full path names for out of tree |
| 22d72948 NC |
33 | * modules must be used. |
