From 28904f4dcea1444adea4b51ba0af32d6c7314101 Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Fri, 9 Oct 2020 10:28:43 +0800 Subject: perf streams: Calculate the sum of total streams hits We have used callchain_node->hit to measure the hot level of one stream. This patch calculates the sum of hits of total streams. Thus in next patch, we can use following formula to report hot percent for one stream. hot percent = callchain_node->hit / sum of total hits Signed-off-by: Jin Yao Acked-by: Jiri Olsa Link: https://lore.kernel.org/r/20201009022845.13141-6-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/stream.h | 1 + 1 file changed, 1 insertion(+) (limited to 'tools/perf/util/stream.h') diff --git a/tools/perf/util/stream.h b/tools/perf/util/stream.h index cb131f41f5b1..a61072eda64d 100644 --- a/tools/perf/util/stream.h +++ b/tools/perf/util/stream.h @@ -14,6 +14,7 @@ struct evsel_streams { int nr_streams_max; int nr_streams; int evsel_idx; + u64 streams_hits; }; struct evlist_streams { -- cgit v1.2.1
