Subject: [PATCH 52/85] perf cs-etm: Add notion of time to decoding code
Date: Tue, 11 Jun 2019 15:58:38 -0300 [thread overview]
Message-ID: <20190611185911.11645-53-acme@kernel.org> (raw)
In-Reply-To: <20190611185911.11645-1-acme@kernel.org>
From: Mathieu Poirier <mathieu.poirier@linaro.org>
This patch deals with timestamp packets received from the decoding
library in order to give the front end packet processing loop a handle
on the time instruction conveyed by range packets have been executed at.
