Jaswinder Singh Rajput cca03c0aeb perf stat: Fix verbose for perf stat ... Error message should use stderr for verbose (-v), otherwise message will be lost for: $ ./perf stat -v <cmd> > /dev/null For example on AMD bus-cycles event is not available so now it looks like: $ ./perf stat -v -e bus-cycles ls > /dev/null Error: counter 0, sys_perf_counter_open() syscall returned with -1 (Invalid argument) Performance counter stats for 'ls': <not counted> bus-cycles 0.006765877 seconds time elapsed.
