From 7841f40aed933dd3838f8d9f2dfcf286c352b7ee Mon Sep 17 00:00:00 2001 From: Jin Yao Date: Thu, 7 Nov 2019 15:47:15 +0800 Subject: perf hist: Count the total cycles of all samples We can get the per sample cycles by hist__account_cycles(). It's also useful to know the total cycles of all samples in order to get the cycles coverage for a single program block in further. For example: coverage = per block sampled cycles / total sampled cycles This patch creates a new argument 'total_cycles' in hist__account_cycles(), which will be added with the cycles of each sample.

So shorten the signature of such functions to receive the 'map_symbol' pointer. This also paves the way to having the 'struct map_groups' pointer in the 'struct map_symbol' so that we can get rid of 'struct map'->groups.

This further paves the way to add 'struct map_groups' to 'struct map_symbol' so that we can have all we need for annotation so that we can ditch 'struct map'->groups, i.e. have the map_groups pointer in a more central place, avoiding the pointer in the 'struct map' that have tons of instances.
