perf evsel: Support printing callchains with arrows
The EVSEL__PRINT_CALLCHAIN_ARROW options can be used to print callchains with arrows for readability. It will be used 'sched timehist' command like below: __schedule <- schedule <- schedule_timeout <- rcu_gp_kthread <- kthread <- ret_from_fork __schedule <- schedule <- schedule_timeout <- rcu_gp_kthread <- kthread <- ret_from_fork __schedule <- schedule <- worker_thread <- kthread <- ret_from_fork Suggested-and-Acked-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/20161116060634.28477-3-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
