Subject: [PATCH 7/9] perf record: Add --all-cgroups option
Date: Wed, 28 Aug 2019 16:31:28 +0900 [thread overview]
Message-ID: <20190828073130.83800-8-namhyung@kernel.org> (raw)
In-Reply-To: <20190828073130.83800-1-namhyung@kernel.org>
The --all-cgroups option is to enable cgroup profiling support. It
tells kernel to record CGROUP events in the ring buffer so that perf
report can identify task/cgroup association later.
