I'm not a kernel hacker, but rather a user that likes expermienting,
and has too much free time (not really) so this is not an expert speaking,
but I will tell you what I have found out while trying to get working modular
sound.
I have a souncard integrated on my Intel Providence motherboard that is based
on the cs4236-chip.
First off i had great trouble to compile my modules w/o unresolved symbols,
a patch downloaded from
ftp://ftp.shout.net/pub/users/mec/patch/sound-module.2176
took care of that, but unfortunately it doesnt apply to later kernel releases.
Then i needed to send the right options to my module (cs4232.o) and the
first ting i needed to to was to add some MODULE_PARM() lines to the cs4232.c
code to be able to set the right parameters like this:
+MODULE_PARM(io, "i");
+MODULE_PARM(irq, "i");
+MODULE_PARM(dma, "i");
+MODULE_PARM(dma2, "i");
then i could set my parameters right and get the module working.
I also found out by running 'kerneld -debug' that when sound-functionality
is asked for by a program it asks for 'char-major-14' which kerneld
automagically translates to sound, which wont work with the new splitted up
approach. By adding 'alias char-major-14 cs4232' to my /etc/conf.modules
i got on demand loading of my sound as well.
My current problem is that with 2.1.78 i cannot compile sound modules that
doesnt generate 'unresolved symbols'. With
CONFIG_SOUND=m
and
CONFIG_CS4232=m
in my .config i get
/lib/modules/2.1.78/misc/sound.o: unresolved symbol attach_mpu401
/lib/modules/2.1.78/misc/sound.o: unresolved symbol probe_mpu401
/lib/modules/2.1.78/misc/sound.o: unresolved symbol unload_mpu401
when i try to insert sound
If i'm missing something obvious please mail me in private and explain that
to me.
cheers!
