* [PATCH] Perf stat: Fix the ratio comments of miss-events @ 2019-11-16 7:48 lqqq341 2019-11-16 14:45 ` Andi Kleen 2019-11-19 15:59 ` Arnaldo Carvalho de Melo 0 siblings, 2 replies; 4+ messages in thread From: lqqq341 @ 2019-11-16 7:48 UTC (permalink / raw) To: peterz, mingo, acme, ak Cc: mark.rutland, alexander.shishkin, jolsa, namhyung, linux-kernel, linux-perf-users, linuxarm, john.garry, zhangshaokun, huangdaode, linyunsheng, liuqi115 From: Qi Liu <liuqi115@hisilicon.com> Perf stat displays miss ratio of L1-dcache, L1-icache, dTLB cache, iTLB cache and LL-cache. Take L1-dcache for example, its miss ratio is caculated as "L1-dcache-load-misses/L1-dcache-loads". So "of all L1-dcache hits" is unsuitable to describe it, and "of all L1-dcache accesses" seems better. The comments of L1-icache, dTLB cache, iTLB cache and LL-cache are fixed in the same way.
