[LITMUS^RT] trace overheads

[shijunjie92]

Hello all:

When I trying to trace the 'LOCK and UNLOCK' overheads, I add 'LOCK' and 'UNLOCK' into the 'IPI_EVENTS' of 'ft-trace-overheads'. But when I do the step 'ft-select-samples counts.csv combined-overheads_*.float32 2>&1 | tee -a overhead-processing.log', errors occurs '[EE] Cutoff for UNLOCK is zero.[EE] Cutoff for LOCK is zero.'. 
I will appreciate it if someone can tell me how to do the lock-related overheads tracing?

Best Wishes!




You Sincerely!
SHI Junjie
