1/* 2 * Trace files that want to automate creationg of all tracepoints defined 3 * in their file should include this file. The following are macros that the 4 * trace file may define: 5 * 6 * TRACE_SYSTEM defines the system the tracepoint is for 7 * 8 * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h 9 * This macro may be defined to tell define_trace.h what file to include. 10 * Note, leave off the ".h". 11 * 12 * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace 13 * then this macro can define the path to use. Note, the path is relative to 14 * define_trace.h, not the file including it. Full path names for out of tree 15 * modules must be used. 16 */ 17 18#ifdef CREATE_TRACE_POINTS 19 20/* Prevent recursion */ 21#undef CREATE_TRACE_POINTS 22 23#include <linux/stringify.h> 24 25#undef TRACE_EVENT 26#define TRACE_EVENT(name, proto, args, tstruct, assign, print) \ 27 DEFINE_TRACE(name) 28 29#undef TRACE_EVENT_FN 30#define TRACE_EVENT_FN(name, proto, args, tstruct, \ 31 assign, print, reg, unreg) \ 32 DEFINE_TRACE_FN(name, reg, unreg) 33 34#undef DECLARE_TRACE 35#define DECLARE_TRACE(name, proto, args) \ 36 DEFINE_TRACE(name) 37 38#undef TRACE_INCLUDE 39#undef __TRACE_INCLUDE 40 41#ifndef TRACE_INCLUDE_FILE 42# define TRACE_INCLUDE_FILE TRACE_SYSTEM 43# define UNDEF_TRACE_INCLUDE_FILE 44#endif 45 46#ifndef TRACE_INCLUDE_PATH 47# define __TRACE_INCLUDE(system) <trace/events/system.h> 48# define UNDEF_TRACE_INCLUDE_PATH 49#else 50# define __TRACE_INCLUDE(system) __stringify(TRACE_INCLUDE_PATH/system.h) 51#endif 52 53# define TRACE_INCLUDE(system) __TRACE_INCLUDE(system) 54 55/* Let the trace headers be reread */ 56#define TRACE_HEADER_MULTI_READ 57 58#include TRACE_INCLUDE(TRACE_INCLUDE_FILE) 59 60#ifdef CONFIG_EVENT_TRACING 61#include <trace/ftrace.h> 62#endif 63 64#undef TRACE_EVENT 65#undef TRACE_EVENT_FN 66#undef TRACE_HEADER_MULTI_READ 67 68/* Only undef what we defined in this file */ 69#ifdef UNDEF_TRACE_INCLUDE_FILE 70# undef TRACE_INCLUDE_FILE 71# undef UNDEF_TRACE_INCLUDE_FILE 72#endif 73 74#ifdef UNDEF_TRACE_INCLUDE_PATH 75# undef TRACE_INCLUDE_PATH 76# undef UNDEF_TRACE_INCLUDE_PATH 77#endif 78 79/* We may be processing more files */ 80#define CREATE_TRACE_POINTS 81 82#endif /* CREATE_TRACE_POINTS */
