4907cb7b | 3 | * Trace files that want to automate creation of all tracepoints defined |
a8d154b0 SR |
4 | * in their file should include this file. The following are macros that the |
5 | * trace file may define: | |
6 | * | |
7 | * TRACE_SYSTEM defines the system the tracepoint is for | |
8 | * | |
9 | * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h | |
10 | * This macro may be defined to tell define_trace.h what file to include. | |
11 | * Note, leave off the ".h". | |
12 | * | |
13 | * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace | |
14 | * then this macro can define the path to use. Note, the path is relative to | |
15 | * define_trace.h, not the file including it. Full path names for out of tree | |
16 | * modules must be used. | |
