From 182bb594e0678b3ceac99f4ec3daa5d22ea3d0ce Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 3 Oct 2022 13:46:46 -0700 Subject: perf tools: Add evlist__add_sched_switch() Add a help to create a system-wide sched_switch event. One merit is that it sets the system-wide bit before adding it to evlist so that the libperf can handle the cpu and thread maps correctly.
