Subject: [PATCH V6 24/25] perf auxtrace: Add option to synthesize events for transactions
Date: Mon, 16 Mar 2015 14:41:46 +0200	[thread overview]
Message-ID: <1426509707-24961-25-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1426509707-24961-1-git-send-email-adrian.hunter@intel.com>

Add AUX area tracing option 'x' to synthesize events for
transactions. This will be used by Intel PT to synthesize
an event record for each TSX start, commit or abort.
