Hi Folks,

my system - dsl 3.2 frugal
my sound driver - sis ( i compiled this driver from source and it depends on ac97.o and ac97_code.o)

i am unable to load the sound driver in bootlocal.sh or .xinitrc
by calling a script. i get unresolved symbol errors.

if i run the script alone after bootup the driver sis.o does load
and i can play music.

but i get a warning as follows

Quote

Warning: loading /home/dsl/sis.o will taint the kernel: no licence

see < http://www.tux.org/lkml/#export-tainted > for information about tainted modules

Modules sis loaded, with warnings

whats happening and how to over come this?

Thanks.

I got a similar message to this when I compiled a driver without the version.h (or .version maybe) file being present.

If you have access to a Knoppix 3.4 CD you can boot from, it might be worth compiling the driver on that to see if the problem disappears.

Hi Juanito,

thanks for the advise but i am not enough of an expert to do that. i merely compiled the driver from sis*.c and sis*h files and was lucky enough to get the sis.o

can you just tell me how to work around my inabilty to run the script in .xinitrc. as i said the module loads when i manually run the script after bootup, and i just ignore the message. what's the difference between running it manually and running it in .xinitrc. is there any argument or something i can use with insmod?

secondly can i bother you to give me a compiled version of sis.o with the .h or .version thing that you told me about if i send you the source code?

Thanks.

If you post the link to the site you downloaded the source binary from here, I'll give it a go if I can.

In the meantime, you could try "insmod -f sis" or "modprobe -f sis" to see if that helps.

Hi Juanito,

very kind of you. thanks. i will try your advise. at the same time let me send the source to your email address.
can i have it because the source was sent as a tar.gz to me by the pc manufacturer.

thanks.

The makefile was definately brief - not even a make install...

I got pretty much the same as you - it looks like the module does not have licensing (GPL) info with it.

Code Sample

# make
gcc -D -DMODULE -isystem /lib/modules/2.4.26/build/include -O2 -Wall -Wstrict-prototypes -fomit-frame-pointer -c -o sis7019.o sis7019.c

# insmod sis7019
Using /lib/modules/2.4.26/kernel/drivers/sound/sis7019.o

/lib/modules/2.4.26/kernel/drivers/sound/sis7019.o:
Hint: You are trying to load a module without a GPL compatible license
and it has unresolved symbols. The module may be trying to access
GPLONLY symbols but the problem is more likely to be a coding or
user error. Contact the module supplier for assistance, only they
can help you.

# modprobe ac97_codec
# insmod sis7019

You may find more information in syslog or the output from dmesg

One thing you could try is an ALSA driver - according to their website, there are drivers for SiS 7012 (intel8x0) and 7018 (trident) chipsets. Maybe one of these is compatible with your SiS 7019?

Hi Juanito,

Thanks. i will see the alsa alternatives
and feedback to you.

have a good day..
