Subject: [PATCH v2 11/17] perf tools: Move thread to traceid_queue
Date: Fri, 24 May 2019 11:35:02 -0600	[thread overview]
Message-ID: <20190524173508.29044-12-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20190524173508.29044-1-mathieu.poirier@linaro.org>

The thread field of structure cs_etm_queue is CPU dependent and as
such need to be part of the cs_etm_traceid_queue in order to support
CPU-wide trace scenarios.
