Subject: [PATCH v3 1/7] perf: Introduce ioctl to communicate driver configuration to kernel
Date:   Wed, 18 Jul 2018 15:48:01 -0600
Message-Id: <1531950487-24554-2-git-send-email-mathieu.poirier@linaro.org>
In-Reply-To: <1531950487-24554-1-git-send-email-mathieu.poirier@linaro.org>
References: <1531950487-24554-1-git-send-email-mathieu.poirier@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Adding a new IOCTL command to communicate PMU specific configuration to
PMU kernel drivers.  This can be anything a PMU might need for
configuration that doesn't fit in the perf_event_attr structure, such
as the CoreSight sink to use for a session.
