The implementation of this feature is based on android systrace: https://source.android.com/devices/tech/debug/ftrace Application developers are more concerned about the performance of the specified application section, added two APIs to implement performance measurement: void sched_note_begin(FAR const char *str); void sched_note_end(FAR const char *str); or SCHED_NOTE_BEGIN(); /* defined to sched_note_begin(__FUNCTION__) */ SCHED_NOTE_END(); /* defined to sched_note_end(__FUNCTION__) */ Signed-off-by: chao.an <anchao@xiaomi.com>
