Subject: [PATCH 03/18] perf, x86: Support PERF_SAMPLE_ADDR on Haswell
Date: Fri, 25 Jan 2013 14:32:57 -0800 [thread overview]
Message-ID: <1359153192-13409-4-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1359153192-13409-1-git-send-email-andi@firstfloor.org>
From: Andi Kleen <ak@linux.intel.com>
Haswell supplies the address for every PEBS memory event, so always fill it in
when the user requested it. It will be 0 when not useful (no memory access)
