As such introducing a central function to be used whenever a traceID value is required. The patch also account for data traceIDs, which are usually I(N) + 1.

coresight: etm-perf: new PMU driver for ETM tracers 2016-02-20T22:11:01+00:00 Mathieu Poirier mathieu.poirier@linaro.org 2016-02-18T00:52:01+00:00 0bcbf2e30ff2271b54f54c8697a185f7d86ec6e4 Perf is a well known and used tool for performance monitoring and much more. A such it is an ideal candidate for integration with coresight based HW tracing. This patch introduces a PMU that represent a coresight tracer to the Perf core.
