Sigmatel 9200 driver

[ardizzo5]

I have decided to try to start to work on a modified driver for the sigmatel 9200 audio chipset, however I have very little experiance working with unix and c++ in a mac atmosphere. Since the 922x audio chips have been made functional, and in windows the driver software supports the entire 92xx family, the answer cannot be far away. However, I am not very familiar with using mac osx and its developer tools. How can I see the code of the original appleHDA kext along with the modified appleHDA kext to support the sigmatel 9220 chips. Can I use xcode to compare them? Another problem is that a 9200 chip is on a high def audio bus with the modem, which complicates the procedure. Is this hi def bus its own independent bus? I am not sure if the 9220 chips share the same characteristic and if they do, the code of the modified HDA kext should help guide the way. With this problem is the fact the the sigmatel audio device is not readily apparent in the system registry, and finding its location is another significant problem. Any details from the modification procedure for the 922x chips would be a huge help, along with any other guidance.

Someone at least tell me if I can look at the code of these kexts using xcode, as I have an 8 hour plane ride tomorrow and I would like to start looking over the code of the modified HDA kexts for the sigmatel 9220 sets. If not xcode, how do I examine the code of these various kext?

Thanks for any help.
