To output metrics with more friendly form, this patch refines the metrics order based on memory hierarchy: "Core Load Hit" => "LLC Load Hit" => "LLC Ld Miss" => "Load Dram" Signed-off-by: Leo Yan Tested-by: Joe Mario Acked-by: Jiri Olsa Link: https://lore.kernel.org/r/20201014050921.5591-4-leo.yan@linaro.org Signed-off-by: Arnaldo Carvalho de Melo --- diff --git a/tools/perf/builtin-c2c.c b/tools/perf/builtin-c2c.c index 51250f37ac9ca..8947a8c48d5aa 100644 --- a/tools/perf/builtin-c2c.c +++ b/tools/perf/builtin-c2c.c @@ -2852,10 +2852,10 @@ static int perf_c2c__report(int argc, const char **argv) "tot_loads," "tot_stores," "stores_l1hit,stores_l1miss," - "dram_lcl,dram_rmt," - "ld_llcmiss," "ld_fbhit,ld_l1hit,ld_l2hit," - "ld_lclhit,ld_rmthit", + "ld_lclhit,ld_rmthit," + "ld_llcmiss," + "dram_lcl,dram_rmt", c2c.display == DISPLAY_TOT ?
