alsa-driver in the kernel

alsa-driver in the kernel

[Peter Ganzhorn]

Hi there,

there are several hints on how to update the in-kernel alsa driver with 
the alsa driver one can download from alsa-project.org, but I had no 
luck at all updating kernel 2.6.14.3 with alsa 1.0.10 - it seems that 
there is something missing in the kernel, but there is nothing more 
mentioned to do in the howtos.

Actually my make process ends like this after updating the in-kernel driver:

  CC      sound/sound_core.o
  CC      sound/sound_firmware.o
  LD      sound/soundcore.o
  LD      sound/arm/built-in.o
  CC      sound/core/hwdep.o
sound/core/hwdep.c: In function `snd_hwdep_open':
sound/core/hwdep.c:84: error: `snd_major' undeclared (first use in this 
function)
sound/core/hwdep.c:84: error: (Each undeclared identifier is reported 
only once
sound/core/hwdep.c:84: error: for each function it appears in.)
make[2]: *** [sound/core/hwdep.o] Error 1
make[1]: *** [sound/core] Error 2
make: *** [sound] Error 2


So my question is if there is a good and up2date howto for updating the 
alsa driver in the kernel with those from alsa-project.org which are 
usually a bit more current.
I do not want to build alsa as modules, because I want a compact kernel 
without many modules.

It would be great if you could tell me what is necessary to do in order 
to get this working! :)

Why are you even trying to do this?
The easiest way is to make all ALSA modules, and then just install 
alsa-driver from alsa-project.org.

If you really have to, just use git.
Get the 2.6.14.3 git tree, and then pull the alsa git into it. It will 
merge it all nicely for you.

Though, this won't give you the very latest version of ALSA, too,
because the latest tree is written for 2.6.15-rcx.  Since some APIs
are incompatible between 2.6.14 and 2.6.15, you have to fix them by
yourselves at your own risk.  So, it's safer simply to use
alsa-driver's build.
