Now that PMU specific configuration is available as part of the event,
lookup the sink identified by users from the perf command line and build
a path from source to sink.

With this functionality it is no longer required to select a sink in a
separate step (from sysFS) before a perf trace session can be started.

+       {ETM_TOKEN_SINK, "sink=%s"},
+       {ETM_TOKEN_ERR, NULL},
+};

Is the above format documented somewhere for the perf users ? If not could
we please
add it ?

Yes definitely.  I will document everything once I am done with
upstreaming the feature.  That way we go over the process only once.

Thanks
