H A D | stat.c | 0e0bf1ea Thu Apr 09 02:07:55 CDT 2020 Jin Yao <yao.jin@linux.intel.com> perf stat: Zero all the 'ena' and 'run' array slot stats for interval mode
As the code comments in perf_stat_process_counter() say, we calculate counter's data every interval, and the display code shows ps->res_stats avg value. We need to zero the stats for interval mode.
But the current code only zeros the res_stats[0], it doesn't zero the res_stats[1] and res_stats[2], which are for ena and run of counter.
This patch zeros the whole res_stats[] for interval mode.
