Hi Steven, I posted some time ago to query about this, but I would like to request this feature again.
That is to intentionally trace or write something at the start and end of a tracing session (trace on and off). I will give you an example about what and how I do it as of now: I first defined an traceevent: XYZ. Then I add this in tracer_tracing_on(): trace_XYZ(some hardware register values) and also in tracer_tracing_off(): trace_XYZ(some hardware register values). Having done that, I have the HW values at least at the start and end, because the worst case is I may not have hit the regular XYZ event tracepoint in the whole session. Does it make sense?
