[LITMUS^RT] Lock overheads tracing

[shijunjie92]

Hello all:

When I trying to trace the lock and unlock overheads of the DPCP.
I set the situation as: normal execution on cpu_0 and critical section on cpu_1.
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? 

Best Wishes!




You Sincerely!
SHI Junjie
