Subject: [PATCH 03/11] x86, perf: Add Top Down events to Intel Atom
Date: Mon,  4 Apr 2016 13:41:46 -0700	[thread overview]
Message-ID: <1459802514-31501-4-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1459802514-31501-1-git-send-email-andi@firstfloor.org>

From: Andi Kleen <ak@linux.intel.com>

Add topdown event declarations to Silvermont / Airmont.
These cores do not support the full Top Down metrics, but an useful
subset (FrontendBound, Retiring, Backend Bound/Bad Speculation).

The perf stat tool automatically handles the missing events
and combines the available metrics.
