Subject: [PATCH 04/10] perf, tools, stat: Scale values by unit before metrics
Date: Tue, 15 Dec 2015 16:54:20 -0800 [thread overview]
Message-ID: <1450227266-2501-5-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1450227266-2501-1-git-send-email-andi@firstfloor.org>
From: Andi Kleen <ak@linux.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.
