A CPU can have many records events. Since RTEMS_RECORD_THREAD_SWITCH_IN is received after RTEMS_RECORD_THREAD_SWITCH_OUT we can just directly write into corresponding CPU file after receiving RTEMS_RECORD_THREAD_SWITCH_IN for the same timestamp. > > 2.

So this particular lttng sched_switch will have prev_* value as RTEMS_RECORD_THREAD_SWITCH_OUT data and next_* value as RTEMS_RECORD_THREAD_SWITCH_IN. -- *Ravindra Kumar Meena*, B. Tech.
