Subject: [PATCH 3/3] x86/events/intel/ds: Add PERF_SAMPLE_PERIOD into PEBS_FREERUNNING_FLAGS
Date:   Thu,  1 Feb 2018 09:38:12 +0100
Message-Id: <20180201083812.11359-4-jolsa@kernel.org>
In-Reply-To: <20180201083812.11359-1-jolsa@kernel.org>
References: <20180201083812.11359-1-jolsa@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Stephan reported that we don't support period for
enabling large PEBS data, which there's no reason
for. Adding PERF_SAMPLE_PERIOD into freerunning
flags.
