Subject: [PATCH 09/15] perf, x86: Support PERF_SAMPLE_ADDR for all PEBS events v3
Date: Sat, 20 Apr 2013 12:19:17 -0700	[thread overview]
Message-ID: <1366485563-16209-10-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1366485563-16209-1-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)

v2: Now include fmt1 too, so it works on Nehalem and later.
v3: Remove extra code inside st|ld if.
