From 962848142335e8b35d522be78f58f2011d976b17 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 20 Mar 2017 13:17:10 -0700 Subject: perf pmu: Add support for MetricName JSON attribute Add support for a new JSON event attribute to name MetricExpr for better output in perf stat. If the event has no MetricName it uses the normal event name instead to describe the metric.
