Subject: [PATCH 20/32] perf, x86: Add Haswell specific transaction flag reporting
Date: Tue, 30 Oct 2012 17:34:11 -0700	[thread overview]
Message-ID: <1351643663-23828-21-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1351643663-23828-1-git-send-email-andi@firstfloor.org>

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

In the PEBS handler report the transaction flags using the new
generic transaction flags facility. Most of them come from
the "tsx_tuning" field in PEBSv2, but the abort code is derived
from the RAX register reported in the PEBS record.
