No, this is for the existing dynamic replicator, which is also compatible with the
one in SoC-600. In the future, we may be able to support multiple trace sessions
(i.e, distinct source-sink pairs using a shared dynamic replicator to filter the
data based on the trace-id). Right now we simple switch off the other side of the
replicator, when we enable the port connected to the sink.
I found these useful while debugging trace generation issue on one of the
platforms.
