System: NetBSD 5.0_BETA (MAC) #2: Fri Nov 28 09:24:53 MET 2008 root@qie:/usr/u/NetBSD/netbsd-5/src/sys/arch/macppc/compile/MAC macppc
Architecture: powerpc
Machine: macppc
>Description:
On my powerbook g4/500 titanium installed with a netbsd-4
userland (and kernel for normal use) I tried to use an actual
customized (mainly awacs activated and fwohci deactivated (see
pr #40051)) netbsd-5 kernel. 'awacs'/'audio' seems to be
detected correctly (dmesg excerpt):
awacs0 at obio0 offset 0x14000 Screamer: irq 24,9,10
awacs0: speaker
audio0 at awacs0: full duplex
, but there is no hear-able built-in speaker output.
But there _is_ hear-able/normal audio headphone output if I
plug in a headphone!? If I remove the headphone there is still
no built-in speaker output.
With the netbsd-4 kernel dmesg output looks shorter:
awacs0 at obio0 offset 0x14000: irq 24,9,10
audio0 at awacs0: full duplex
, but built-inspeaker output works! To activate headphones
output I had to manually switch it via 'mixerctl':
mixerctl -w monitor.output=headphones
, which seems to be done automatically with the netbsd-5
kernel.
>How-To-Repeat:
Boot a customized, 'awacs' and 'audio at awacs' activated,
netbsd-5 kernel on a powerbook g4/500 titanium and try to
produce built-in speaker output ('ogg123 test.ogg' in my
case). Built-in speaker output does not not work for me, but
just plugging in headphones produce normal headphones output.
>Fix:
Unknown.

Sounds like you just found Yet Another Wiring Variant for awacs'
headphone detect gpio.
Please try this pseudo patch to macppc/dev/awacs.c:
static int
awacs_check_headphones(struct awacs_softc *sc)
{
uint32_t reg;
reg = awacs_read_reg(sc, AWACS_CODEC_STATUS);
- DPRINTF("%s: codec status reg %08x\n", device_xname(sc-
>sc_dev), reg);
+ printf("%s: codec status reg %08x\n", device_xname(sc-
>sc_dev), reg);
return ((reg & sc->sc_headphones_mask) == sc-
>sc_headphones_in);
}
Boot a kernel with this and then plug and unplug headphones a few
times. The kernel should output the gpio readings every time you
(un)plug them. Please mail me the output, this should help me to find
out which bit is the headphone status on your particular PowerBook.
Alternatively you can just add 'options AWACS_DEBUG' to your kernel
config but that would probably give too much output.
Also, please tell me what's in your PowerBook's /compatible property
( Should be something like 'PowerBook5,3' ) so I can add a machine-
specific entry to awacs' quirks table.

I did: 'awacs' related kernel output is:
awacs0 at obio0 offset 0x14000 Screamer: irq 24,9,10
awacs0: awacs0: codec status reg 00403100
speaker
audio0 at awacs0: full duplex
Headphones plug in yields: <------------
|
awacs0: codec status reg 00403108 |
|
Headphones unplugging yields: |
|
awacs0: codec status reg 00403100 |
|
... and so on. -------------------------
'mixerctl monitor.output' correctly reflects the headphones plug-in
state by stating
monitor.output=speaker
if no headphones are plugged in and
monitor.output=headphones
if they are plugged in.
