Hi Steve, If my understanding is right, I think both are not the same. The predefined field relates to the current process which was interrupted by the hrtimer. This I guess does not have a meaning in this context. Mostly it is the idle process which is interrupted by the hrtimer. But the ccomm field refers to the task woken up by the process. The latencies are measured for this task. So I it is needed. -Binoy
