Re: [linuxtools-dev] [TMF] eclipscon2014 presentation

Hi Hisham,
Thanks for your interest!
Right now (with the patch that Florian linked to previously), the
data-driven time graph view only displays rectangles of different
colors. But the "real" time graph view in TMF also supports displaying
arrows from one state to another, as well as text labels in the
rectangles themselves. For example, the LTTng Control Flow View makes
uses of these features. They haven't been implement in the
XML-data-driven view yet, but it's definitely planned.
Also, having a view/dialog to generate the XML file for the user is
indeed the end goal. But the work on this whole data-driven framework is
just getting started, so it is still some time out. We'll first focus on
making the different types of views available from XML, and on the file
format itself. Then we can look at how to generate those XML files in a
convenient way.
Cheers,
Alexandre

Hi Florian,
Your example works fine!
Regarding the address bus representation, you are right, this is
another way of representing the same data (but so convenient to me to
check any value change in a specific trace). Also I think rectangles
are fine enough, the missing thing is only the value inside the
rectangle. The other way may be to use the XY graph to represent the
values, but sometimes this representation is less convenient.
I am also interested by the idea of XML code generator. I would
imagine in my ideal TMF (a right click on a trace and then a nice GUI
helping to specify how we want to represent it ... eg digital bus, XY
graph, text, or whatever ...). Have you already started some work in
this area?
Thanks again for your help,
Hisham

Hi,
I updated the GDB.UST.xml file with the current XML definition.
So I think it works with the patch 23161.
You have one trace example in the same github ("Sample UST trace.zip").
To answer quickly to your question, there is no view to show a
digital bus.
But we have the Control Flow and I think that it's just another way to
draw the information. Currently we draw only rectangle in the Control
Flow. I'm not an expert on this part but other people on this mailing
list can better answer.
Cheers,
Florian

Hi Florian,
Thanks for your reply, I merged the XML control flow view patch, I
should be ready to use it now.
Also, from the following repository
(https://github.com/fwininger/XML4TMF), I imported you GDB traces and
the related GDB.UST.xml, but unfortunately it failed because of a
parsing error ... I guess the GDB.UST.xml file is too old and is no
longer compliant with your patch. Could you kindly help to setup the
GDB example first?
I would also be happy to have some views allowing digital bus
representation (see screenshots
http://wsim.gforge.inria.fr/tutorials/msp430-adc/ch03.html). Does TMF
with your current work can do that?
Cheers,
Hisham
Hi Hisham,
The XML based views are not currently in the master branch, but you can
try the XML control flow view with this patch in review :
https://git.eclipse.org/r/#/c/23161/
The XML definition is already in TMF, you can find an example here :
https://git.eclipse.org/r/#/c/23159/7
To import a new XML file, right click on "Traces" in the workspace ->
"Import XML file".
If you have already a good idea of the data you want to display, I can
help you to configure the view.
Cheers,
Florian
