/* * Trace files that want to automate creation of all tracepoints defined * in their file should include this file. The following are macros that the * trace file may define: * * TRACE_SYSTEM defines the system the tracepoint is for * * TRACE_INCLUDE_FILE if the file name is something other than TRACE_SYSTEM.h * This macro may be defined to tell define_trace.h what file to include. * Note, leave off the ".h". * * TRACE_INCLUDE_PATH if the path is something other than core kernel include/trace * then this macro can define the path to use. Note, the path is relative to * define_trace.h, not the file including it. Full path names for out of tree * modules must be used. */ #ifdef CREATE_TRACE_POINTS /* Prevent recursion */ #undef CREATE_TRACE_POINTS #include <linux/stringify.h> #undef TRACE_EVENT #define TRACE_EVENT(name, proto, args, tstruct, assign, print) \ DEFINE_TRACE(name) #undef TRACE_EVENT_CONDITION #define TRACE_EVENT_CONDITION(name, proto, args, cond, tstruct, assign, print) \ TRACE_EVENT(name, \ PARAMS(proto), \ PARAMS(args), \ PARAMS(tstruct), \ PARAMS(assign), \ PARAMS(print)) #undef TRACE_EVENT_FN #define TRACE_EVENT_FN(name, proto, args, tstruct, \ assign, print, reg, unreg) \ DEFINE_TRACE_FN(name, reg, unreg) #undef DEFINE_EVENT #define DEFINE_EVENT(template, name, proto, args) \ DEFINE_TRACE(name) #undef DEFINE_EVENT_FN #define DEFINE_EVENT_FN(template, name, proto, args, reg, unreg) \ DEFINE_TRACE_FN(name, reg, unreg) #undef DEFINE_EVENT_PRINT #define DEFINE_EVENT_PRINT(template, name, proto, args, print) \ DEFINE_TRACE(name) #undef DEFINE_EVENT_CONDITION #define DEFINE_EVENT_CONDITION(template, name, proto, args, cond) \ DEFINE_EVENT(template, name, PARAMS(proto), PARAMS(args)) #undef DECLARE_TRACE #define DECLARE_TRACE(name, proto, args) \ DEFINE_TRACE(name) #undef TRACE_INCLUDE #undef __TRACE_INCLUDE #ifndef TRACE_INCLUDE_FILE # define TRACE_INCLUDE_FILE TRACE_SYSTEM # define UNDEF_TRACE_INCLUDE_FILE #endif #ifndef TRACE_INCLUDE_PATH # define __TRACE_INCLUDE(system) <trace/events/system.h> # define UNDEF_TRACE_INCLUDE_PATH #else # define __TRACE_INCLUDE(system) __stringify(TRACE_INCLUDE_PATH/system.h) #endif # define TRACE_INCLUDE(system) __TRACE_INCLUDE(system) /* Let the trace headers be reread */ #define TRACE_HEADER_MULTI_READ #include TRACE_INCLUDE(TRACE_INCLUDE_FILE) /* Make all open coded DECLARE_TRACE nops */ #undef DECLARE_TRACE #define DECLARE_TRACE(name, proto, args) #ifdef CONFIG_EVENT_TRACING #include <trace/ftrace.h> #endif #undef TRACE_EVENT #undef TRACE_EVENT_FN #undef TRACE_EVENT_CONDITION #undef DECLARE_EVENT_CLASS #undef DEFINE_EVENT #undef DEFINE_EVENT_FN #undef DEFINE_EVENT_PRINT #undef DEFINE_EVENT_CONDITION #undef TRACE_HEADER_MULTI_READ #undef DECLARE_TRACE /* Only undef what we defined in this file */ #ifdef UNDEF_TRACE_INCLUDE_FILE # undef TRACE_INCLUDE_FILE # undef UNDEF_TRACE_INCLUDE_FILE #endif #ifdef UNDEF_TRACE_INCLUDE_PATH # undef TRACE_INCLUDE_PATH # undef UNDEF_TRACE_INCLUDE_PATH #endif /* We may be processing more files */ #define CREATE_TRACE_POINTS #endif /* CREATE_TRACE_POINTS */
