Subject: [PATCH 57/75] perf cs-etm: Add configuration for ETMv3 trace protocol
Date: Thu, 6 Dec 2018 18:25:44 -0300 [thread overview]
Message-ID: <20181206212602.20474-58-acme@kernel.org> (raw)
In-Reply-To: <20181206212602.20474-1-acme@kernel.org>
From: Mathieu Poirier <mathieu.poirier@linaro.org>
This patch deals with the proper initialisation of configuration
parameters for the ETMv3 trace protocol in order to properly handle
packets generated by tracers following this specification.
