Message-Id: <1461787251-6702-9-git-send-email-andi@firstfloor.org> Date: Wed, 27 Apr 2016 13:00:48 -0700 From: Andi Kleen <andi@...stfloor.org> To: acme@...nel.org Cc: peterz@...radead.org, jolsa@...nel.org, linux-kernel@...r.kernel.org, Andi Kleen <ak@...ux.intel.com> Subject: [PATCH 08/11] perf, tools, stat: Scale values by unit before metrics From: Andi Kleen <ak@...ux.intel.com> Scale values by unit before passing them to the metrics printing functions. This is needed for TopDown, because it needs to scale the slots correctly by pipeline width / SMTness. For existing metrics it shouldn't make any difference, as those generally use events that don't have any units.
