| | 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 |
| | 32 | * tracepoint_event.h, not the file including it. Full path names for out of tree |
| | 33 | * modules must be used. |
