| |
Add top.children config option for setting default value of callchain accumulation. It affects the output only if one of -g or --call-graph option is given as well.
A user can write .perfconfig file like below to enable accumulation by default:
$ cat ~/.perfconfig [top] children = true
And it can be disabled through command line:
$ perf top --no-children
