Subject: [PATCH 53/85] perf cs-etm: Add support for CPU-wide trace scenarios
Date: Tue, 11 Jun 2019 15:58:39 -0300 [thread overview]
Message-ID: <20190611185911.11645-54-acme@kernel.org> (raw)
In-Reply-To: <20190611185911.11645-1-acme@kernel.org>
From: Mathieu Poirier <mathieu.poirier@linaro.org>
Add support for CPU-wide trace scenarios by correlating range packets
with timestamp packets. That way range packets received on different
ETMQ/traceID channels can be processed and synthesized in chronological
order.
