HDA codec graphing

HDA codec graphing

[Claudio Matsuoka]

After a lot of time published only as a git repository, I created a
page and tarball for Eduardo Habkost's codecgraph tool to graph the
layout of HDA codecs. It may be useful for those tweaking or
troubleshooting existing drivers. The page has also examples of
different codec layouts rendered in SVG. See details at
http://helllabs.org/codecgraph/.

Nice.  Then we shouldn't change the proc output format any more, or at
least, keep codecgraph working :)

I think it's worth to include this to the ALSA upstream repo.
Any other useful stuff?  Maybe Tobin's script would be good.

Or, maybe it's better to keep outside so that other people can change
more freely than on alsa-project.org...

Change the format as needed, as long as it is unambiguous and contains
all the necessary information we'll keep the tool up to date.

The grapher is still unstable, keeping it outside would probably be
better for now.

I ran this on my home system (Intel DP965LT - STAC9227).  Attached is
the graph to add to your samples.

I also am submitting the first (of possibly many) patches.  This one
will also look in the $PWD for the codecgraph.py file, so users who
don't wish to install this can just download and run it in place.

I noticed a few output errors as well:

        6: Unknown item: No Modem Function Group found
        10: Unknown item: Default PCM:

But as I am not yet familiar with python, I'd like to just report these
for now.

As to "my script", first let me clarify that it isn't mine.  A user
(wishie) on #alsa at irc.freenode.net worked with me to develop it, but
he deserves full credit.  On that note, these both should be added to
alsa-utils or alsa-tools and to the main web site.  Together, they will
make development/debug much nicer.

Could you send me the subdevice ID and the codec file? We store the
samples in codec file format (instead of the generated ps/svg/png
files).

Thanks. In fact the tool is Eduardo's, I added the wrapper shell
instead of building that functionality into the Python script exactly
because I'm not familiar with Python as well, but I though this script
was a good excuse to learn it ;) So eventually (soon, I hope) I'll
change the main script to pipe the output directly into graphviz and
get rid of the wrapper.

Added, thanks. I also changed the way it finds the python script so
you'll be able to run it from the same path as the wrapper script.
