Hello, I tried the perf-hello.c file and found the results as you explained. It is very helpful to me. Now, for PERF_COUNT_HW_BRANCH_MISSES, I am getting varying values every time unlike PERF_COUNT_HW_INSTRUCTIONS. To get count for only defined process, I am trying to set perf_event_attr structure variables sample_type as PERF_SAMPLE_BRANCH_STACK and branch_sample_type as PERF_SAMPLE_BRANCH_USER. By doing so, I am getting error no. 5 by perf_event_open. What may be the problem?
