Apple Tumbler and Snapper audio: looking for testers

[Marco Trillo]

Hi all,

I've implemented audio output for the "Tumbler" and "Snapper" Apple
I2S-based audio devices.

The machine I have is a eMac G4, but these devices are found on a lot
of G3 and G4 systems.
In particular, all iMac G4's, all eMacs, all iBook G4's and most of
PowerBook G4's have either "Tumbler" or "Snapper".

The following is a more detailed list. Anyone interested in testing
it?  Below is more information on how to obtain it.

Thanks a lot!

iMacs:
- "PowerMac4,2" iMac G4 (2002) [tumbler]
- "PowerMac4,5" iMac G4 17'' [tumbler]
- "PowerMac6,1" iMac G4 17'' (2003) [tumbler?]
- "PowerMac6,3" iMac G4 20'' (Nov 2003) [snapper?]

eMacs:
- "PowerMac4,4" eMac G4 (2002, 2003) [snapper]

- "PowerBook5,3" PowerBook G4 [snapper]
- "PowerBook5,4" PowerBook G4 [snapper]
- "PowerBook5,5" PowerBook G4 [snapper]
- "PowerBook5,6" PowerBook G4 [snapper]
- "PowerBook5,7" PowerBook G4 [snapper?]
- "PowerBook6,1" PowerBook G4 [snapper]
- "PowerBook6,2" PowerBook G4 [snapper]
- "PowerBook6,4" PowerBook G4 [snapper]
- "PowerBook6,7" PowerBook G4 [snapper]
- "PowerBook6,8" PowerBook G4 [snapper]

The driver can be obtained in the following tarball:
<http://www.telefonica.net/web2/marco2z/fbsd/aoa1.tgz>

It includes the "sound/" and "powermac/" subdirectories to include in
the kernel,  something like this:
$ cp -R sound/macio /usr/src/sys/dev/sound/macio
$ cp powermac/* /usr/src/sys/powerpc/powermac/

In addition, the "patches/" subdirectory contains the following patches:
 - macio.patch to apply in /usr/src/sys/powerpc/powermac
 - files.patch to apply in /usr/src/sys/conf
 - generic.patch to apply in /usr/src/sys/powerpc/conf, for the GENERIC kernel.

If you don't use the GENERIC kernel you can also enable it manually by
including the following lines:

device sound
device davbus
device i2s

And of course, some dmesg output from my machine. It's very verbose
due to debug being enabled:
