[alsa-devel] HDA codec graphing
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).
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.

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.

It is just a warning because the script doesn't know what those lines mean. But those lines are simply ignored and it shouldn't cause problems.
I have just changed the script to not give a warning on those cases.

Thanks, is that an Intel DG965SS board?
