6、宏TRACE_EVENT()第6次的展开: 定义了函数”trace_event_define_fields_##call()”,把TP_STRUCT__entry()结构体中各成员,转换成ftrace_event_field链表,供后面trace_event filter功能来使用。在events对应的”format”文件中,可以看到这些field的定义。 // (1)TRACE_EVENT() = DECLARE_EVENT_CLASS();DEFIN...
trace_event=[event-list] event-list是逗号分隔的event列表。 3、Defining an event-enabled tracepoint 怎么样定义一个event-enabled的tracepoint,可以参考内核代码:samples/trace_events 4、Event formats 每个trace event都有一个与它相关联的“format”文件,该文件包含log event中每个字段的描述。这个信息用来解析...

common信息: 这部分有系统根据当前是 “Normal format” 还是 “Latency trace format”,选择使用 trace_print_context() 或者是 trace_print_lat_context() 函数来进行格式化。 用户trace信息: 这部分根据 type 字段找到对应的 trace_event 结构,根据其 event->funcs->trace() 函数来进行格式化。遵循谁存储谁解析...
