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] - "PowerMac6,4" eMac G4 (2004, 2005) [snapper] iBooks: - "PowerBook4,1" iBook G3 (May 2001) [tumbler] - "PowerBook4,2" iBook G3 [tumbler?] - "PowerBook4,3" iBook G3 (2002, 2003) [tumbler] - "PowerBook6,3" iBook G4 (2003) [snapper] - "PowerBook6,5" iBook G4 (2004) [snapper] - "PowerBook6,7" iBook G4 (2005) [snapper] PowerMacs: - "PowerMac3,4" PowerMac G4 "Digital audio" [tumbler] - "PowerMac3,5" PowerMac G4 "QuickSilver" [tumbler] - "PowerMac3,6" PowerMac G4 "Mirrored drive doors" [snapper] PowerBooks: - "PowerBook3,3" PowerBook G4 "Gigabit ethernet" [tumbler] - "PowerBook3,4" PowerBook G4 "DVI" [snapper] - "PowerBook3,5" PowerBook G4 [snapper] - "PowerBook5,1" PowerBook G4 [snapper] - "PowerBook5,2" PowerBook G4 [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: pcm0: <i2s> mem 0x10000-0x10fff,0x8000-0x80ff,0x8100-0x81ff irq 30,1,2,31,3,4 on macio0 interrupting at irq 1 pcm0: [ITHREAD] GPIO <headphone-mute>: addr 0x6f GPIO <amp-mute>: addr 0x70 GPIO <audio-hw-reset>: addr 0x75 interrupting at irq 61 pcm0: [ITHREAD] GPIO <headphone-detect>: addr 0x67 enabled outputs: SPEAKER resetting codec [...] kiic0: <Keywest I2C controller> mem 0x18000-0x18fff irq 26 on macio0 [...] pcm0: codec: <snapper> at address 6Ah on kiic0 $ cat /dev/sndstat FreeBSD Audio Driver (newpcm: 32bit 2007061600/powerpc) Installed devices: pcm0: <i2s> at i2s [GIANT] (1p:1v/0r:0v channels default) Thanks and regards!
