From 0434410fa45c9aff6183bb99e0fbc255d75fcf95 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Thu, 7 Nov 2024 08:20:34 -0800 Subject: perf jevents: Add map_for_cpu() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The PMU is no longer part of the map finding process and for metrics doesn't make sense as they lack a PMU.
