From 56f0fd45d8df51542930b9b2e1acee5034b53479 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 11 Mar 2015 08:28:01 -0700 Subject: [PATCH] perf stat: Fix IPC and other formulas with -A perf stat didn't compute the IPC and other formulas for individual CPUs with -A. Fix this for the easy -A case. As before, --per-core and --per-socket do not handle it, they simply print nothing.
