Subject: [PATCH v3 10/13] kernel: events: Export perf_report_aux_output_id()
Date: Tue, 9 Aug 2022 23:33:58 +0100 [thread overview]
Message-ID: <20220809223401.24599-11-mike.leach@linaro.org> (raw)
In-Reply-To: <20220809223401.24599-1-mike.leach@linaro.org>
CoreSight trace being updated to use the perf_report_aux_output_id()
in a similar way to intel-pt.
This function in needs export visibility to allow it to be called from
kernel loadable modules, which CoreSight may configured to be built as.
Signed-off-by: Mike Leach <mike.leach@linaro.org>
