Subject: [PATCH 36/49] perf tools: Add cpu into struct perf_mmap
Date: Tue, 9 Jan 2018 16:35:09 +0100 [thread overview]
Message-ID: <20180109153522.14116-37-jolsa@kernel.org> (raw)
In-Reply-To: <20180109153522.14116-1-jolsa@kernel.org>
It will be useful in following patch to pin thread
to cpu based on the map it processes.
