Subject: [PATCH 4/9] perf c2c record: Record physical addresses in samples
Date: Fri, 9 Mar 2018 11:14:37 +0100 [thread overview]
Message-ID: <20180309101442.9224-5-jolsa@kernel.org> (raw)
In-Reply-To: <20180309101442.9224-1-jolsa@kernel.org>
We are going to display NUMA node information in following
patches. For this we need to have physical address data in
the sample.
Adding --phys-data as a default option for perf c2c record.
