<DIV>Hello all:</DIV>
<DIV> </DIV>
<DIV>When I trying to trace the lock and unlock overheads of the DPCP.</DIV>
<DIV>I set the situation as: normal execution on cpu_0 and critical section on
cpu_1.</DIV>
<DIV>As a consequence: LOCK_START located on cpu_0, LOCK_END located on
cpu_1, UNLOCK_START located on cpu_1 and UNLOCK_END located on
cpu_0. That means the pair of events located on different cpu recording buffer.
So how can I calculate the overheads of lock and unlock in that
situation? </DIV>
