Subject: [PATCH 0/6] perf: Add ioctl for PMU driver configuration 
Date:   Mon,  2 Jul 2018 16:33:24 -0600
Message-Id: <1530570810-28929-1-git-send-email-mathieu.poirier@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This set follows what has been done for filters by adding an ioctl
to communicate PMU specific driver configuration to the kernel.

Patch 01 and 02 provide the functionality in user space while patch 04
and 05 take care of the kernel part.  Patches 03 and 06 use the newly
added functionality to communicate the selection of CoreSight sink
for each event.

This functionality is needed to identify the CoreSight sink to use when
working with CPU-wide trace scenarios.  It also paves the way to support
complex tracer configurations where dozens of trace parameters need to
be communicated to the CoreSight PMU driver.

Applies cleanly on v4.18-rc3.

Best regards,
Mathieu
