unresolved symbol udelay with ALSA on PPC

unresolved symbol udelay with ALSA on PPC

[Jörn Nettingsmeier]

hi !

sorry for crossposting, this one is probably inappropriate for either
the alsa or the ppc list. the problem is, i don't know which ;)

this is after successfully compiling 2.4.19-pre8-ben0 for PPC on a
powerbook g3 (pismo) and installing the alsa drivers from
alsa-driver-0.9.0rc1.tar.bz2:

ephraim:/usr/src/alsa-driver-0.9.0rc1 # depmod -ae -F
/boot/System.map-2.4.19-pre8-ben0
depmod: *** Unresolved symbols in
/lib/modules/2.4.19-pre8-ben0/kernel/sound/ppc/snd-powermac.o
depmod:         udelay

can anyone clue me in on this ? i grepped for udelay, but it seems it's
a very popular string in the source tree, so i gave up :( it seems to be
defined alright for other kernel modules. afaics, snd-powermac is the
only one that has problems.

thanks in advance,

jörn

I think that we fixed this problem in CVS. Probably, inclusion of 
<linux/delay.h> header file was missing.

i hope it was fixed on cvs now.
(as always, it's due to missing include..)
could you try to update?

anyway, i'll spend some time to debug powermac drivers in this week.
there have been bug reports regarding awacs/screamer chips.

the tumbler chip was fixed in the last week.
now it supports bass/treble and DRC, and the volume changes more
reasonably.

takashi, jaroslav, thanks for your quick replies. cvs compiles and runs.
problem is, i hear no sound.

here's another (screamer/awacs):

ephraim:/ # amixer

  Playback channels: Front Left - Front Right
  Capture channels: Mono

i can aplay a wav, but i don't hear anything, no matter how i switch
around...

the switches look weird to me:

master is a gain slider, mutable and recordable. ok.
line, cd and mic are just capture switches, neither gain nor mute. and
they are non-exclusive. by default, all 3 are set to capture.
mic boost is just a mute switch, which is probably what it should be.
pc speaker is a mutable gain slider like it used to be.
capture can't  be muted, but i think that's how the hardware is.
beep looks ok.
