| 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 | * TRACEPOINT_SYSTEM defines the system the tracepoint is for: |
| 25 | * < [com_company_]project_[component_] > |
| 26 | * |
| 27 | * TRACEPOINT_INCLUDE_FILE if the file name is something other than |
| 28 | * TRACEPOINT_SYSTEM.h. This macro may be defined to tell |
| 29 | * define_trace.h what file to include. Note, leave off the ".h". |
| 30 | * |
| 31 | * TRACEPOINT_INCLUDE_PATH if the path is something other than core |
| 32 | * kernel include/trace then this macro can define the path to use. |
| 33 | * Note, the path is relative to tracepoint_event.h, not the file |
| 34 | * including it. Full path names for out of tree modules must be |
| 35 | * used. |
