[Tracing] Deciding the Yaml configuration for barectf input

Hey Guillaume!

RTEMS trace, if any. And what are your plan on this aspect once you can
output CTF traces with >RTEMS?

RTEMS wiki pages do suggest using trace compass for the purpose of
visualization of traces [1]. It seems like a good choice.

For sure! I look forward to it.

>Also, my two cent for your question is that you are much better
integrating CTF gen directly in RTEMS if modification to babeltrace source
code would be required. I think it >would be simpler to upstream your
changes that way.

Yes that would be simpler. But at some point in time I will have to decide
on a CTF structure for the output traces. I suspect this knowledge will
also be used when changing the babeltrace source code for RTEMS trace
format conversion. And hence the urgent need for advice :p

Thanks for the input:)
