In case the application is an RTEMS application running inside Qemu, <br>
then of course babletrace will have problems to understand the record <br>
item steam since it is not in CTF format. We have the following situation:<br>
<br>
[ RTEMS application with event recording running on Qemu ]<br>
<- TCP stream of record items -><br>
[ babeltrace ]<br>
<br>
What we probably need is something like this:<br>
<br>
[ RTEMS application with event recording running on Qemu ]<br>
<- TCP stream of record items -><br>
[ custom converter program ]<br>
<- TCP stream of CTF data -><br>
[ babeltrace ] or [ Trace Compass ]<br></blockquote><div><br></div><div>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. </div><div><br></div><div>With LTTng-UST I was able to define tracepoint provider package and tracepoints in the program.
