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 [thread overview]
Message-ID: <20180201083812.11359-4-jolsa@kernel.org> (raw)
In-Reply-To: <20180201083812.11359-1-jolsa@kernel.org>
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.
Reported-by: Stephane Eranian <eranian@google.com>
