From 60ea006f72512fd7c36f16cdbe91f4fc284f8115 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 3 Oct 2022 13:46:45 -0700 Subject: perf tools: Get rid of evlist__add_on_all_cpus() The cpu and thread maps are properly handled in libperf now. No need to do it in the perf tools anymore. Let's remove the logic.
