<p class="MsoNormal">Greetings, <br>
i am running a project on behalf or Ericsson Sweden regarding tracing on a custom multicore architecture.
<br>
<br>
I came across your tools through a colleague and It seems that they might be appropriate for our work, especially TMF since we already utilize
<br>
eclipse quite heavily. <br>
<br>
I have some technical questions though, and I would like some feedback so I know whether our specifications can be covered by that or some similar tool.
<br>
<br>
Please forward this email to the appropriate department if possible. <br>
<br>
The specifications we have are:<br>
1. The trace we are interested in is a process-centric view of the events (or actors in our system) along with their respective threads, that will run on specific cores.
<br>
2. We don’t need to capture the traces, that has been already done, only to parse the generated file and produce a graphical view that includes the processes, threads, cores and the messages that trigger new processes.
<br>
is that possible?<br>
3. We have the trace files in .lat format already which are generated by using the Flexus tools. What I want to know if there is a conversion tool available or we need to develop a script to do the conversion to a suitable format (CTF). And if the TMF or LTTV
can produce this result from a custom trace file and not a kernel trace.<br>
<br>
Observe on Fig 1 a simplified view of our needs. In practice there will be a few thousands processes in tens of cores and the start/end times and the messages are essential.<br>
<br>
Fig 1: Example of result wanted.<br>
