Yes it is. CTF is an efficient trace format (based on research done for LTTng) that can be used for essentially anything (kernel, user-space, hardware, ...)
We will also provide a CTF parser with Juno (we have a few wrinkle to iron out but it is practically ready for a CQ). It should appear in HEAD (well, 'master') shortly.
Although TMF and LTTng will have a dependency on it, this CTF parser generator will be a component on its own that can be re-used without the rest (event without Eclipse...)

Hi,
Excellent.
I've read somewhere that one CTF objective is to be system-agnostic (even if, for now, focused only on linux). Is it still true ?
Many thanks,
Xavier

Hi,
You can start by looking at TMF itself. Some if not most of the LTTng
views/widgets are really generic TMF views/widgets that have been
extended for LTTng purposes.
For the context-switching et al., we initially simply ported the
GTK-based LTTV's State System (the component that handles the
processes/resources state transitions based on the events sequence).
This State System is really Linux kernel-oriented.
We are now working on a persistent generic State System (a part of TMF
itself) that will be re-usable for any type of state management. It
should be integrated in the coming months and delivered with Juno. You
might want to consider basing your work on this. Constraint: Although
the new State System will be trace-format agnostic, for the initial
release we are likely to focus on CTF (Common Trace Format) traces.
Don't hesitate to contact us for more details.

Hi,
In the coming weeks, I will start to design a GUI to display traces
for a massively parallel device.
My first idea was to use TMF for that - and do something similar to
the LTT-ng plugin.
For now, this device does not run linux, but the traced event will
be very similar (context-switches, interrupts, user events...)
Is there any hint available somewhere, or any trap to avoid ?
Many thanks,
