In case the application is an RTEMS application running inside Qemu,
then of course babletrace will have problems to understand the record

[ babeltrace ]
What we probably need is something like this:
[ RTEMS application with event recording running on Qemu ]
<- TCP stream of record items ->
[ custom converter program ]
<- TCP stream of CTF data ->
[ babeltrace ] or [ Trace Compass ]
Okay. Thanks for the clarification. The small example that I showed
you where CTF data was printed in text format using babeltrace. It
requires LTTng-UST. We can't use it because you had already mentioned
that there is a license problem with it.
With LTTng-UST I was able to define tracepoint provider package and
tracepoints in the program. You can follow this link in case if you
wanna have a look at it again.
https://lttng.org/docs/v2.10/#doc-tracing-your-own-user-application
Without the help of LTTng-UST how we will be able to define
tracepoints in the program?
Defining tracepoints in RTEMS applications is currently outside the
scope of this project. You should really focus on the things mentioned
in ticket:
https://devel.rtems.org/ticket/3696
The primary goal is to convert the record item stream into something which
Trace Compass understands. As a first step, you can simplify this to: convert
the record item stream into a CTF stream which babeltrace understands.
