CTF is not Linux specific, the multicore association tool infrastructure work group was involve to define the requirement/spec.
Yes LTTng/Linux/Eclipse is the only open source implementation so fare but the good news is if you are using CTF for other use cases e.g. HW tracing, you will be able to re-use many cmpts, e.g. parser (both Java and C/C++) and many views/correlation in Eclipse

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,
Xavier Raynaud
