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 | * | |
8d8a24c8 MD |
24 | * TRACEPOINT_SYSTEM defines the system the tracepoint is for: |
25 | * < [com_company_]project_[component_] > | |
22d72948 | 26 | * |
8d8a24c8 MD |
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". | |
22d72948 | 30 | * |
9b22dc6b MD |
31 | * TRACEPOINT_INCLUDE_PATH if the path is something other than within |
32 | * the system's include/tracepoint/ path, then this macro can define | |
33 | * the path to use. This path is relative to tracepoint-event.h, or | |
34 | * to the include search path. Trick: Use a | |
35 | * #define TRACEPOINT_INCLUDE_PATH . | |
36 | * combined with -Ipath_to_header as compiler argument to allow | |
37 | * searching for a header within your project build tree. | |
