[Alsa-devel] 1.0.0pre1: au88x0 driver locks up kernel

2003-11-19 Thread Carolyn and Eric Hathaway
I'm running RedHat 7.3 (RH kernel 2.4.20-20.7, gcc 2.96-113), and have a
generic Aureal Vortex 1 card (au8820 chipset).  Compiling and installing
the 1.0.0pre1 ALSA driver works fine, but if I do a 'modprobe
snd-au8820', the computer locks up instantly (can't even ssh in from
another computer).
Going back through recent CVS commits, I found that the problem is
caused by the changes described in the following alsa-cvslog message:
http://sourceforge.net/mailarchive/message.php?msg_id=6552838

Specifically, the problem is caused by the changes Takashi made to
au88x0.h and au88x0.c to eliminate calls to pci_request_regions() and
pci_release_regions().  If I revert those two files to their previous
versions, the driver compiles and works fine.  I'm not an ALSA driver
guru, but I didn't see anything immediately wrong with the changes
introduced by the above CVS commit that would cause such a drastic
kernel error.  Perhaps someone more familiar with the code in question 
could take another look at those changes?

Regards,
-Eric Hathaway

[Alsa-devel] aureal driver compile problem and patch

2003-10-30 Thread Carolyn and Eric Hathaway
(I already attempted to send this message to the list once before I 
subscribed, but it never showed up in the archives.  My apologies if 
this ends up being a duplicate post. -ELH)

Hello,

I'm running RedHat 7.3 with all updates applied (including RedHat's 
kernel version 2.4.20-20.7), with a generic OEM Aureal Vortex soundcard 
(au8820 chip).  On this system, I compiled ALSA driver 0.9.8 with the 
following options:

[EMAIL PROTECTED] alsa-driver-0.9.8]$ ./configure --with-isapnp=no 
--with-sequencer=yes --with-oss=yes --with-cards=au8820

Performing a 'make; make install' ends with a message saying that there 
are unresolved symbols in module snd-au8820.o.  Digging a bit deeper, we 
can find which symbols are unresolved:

[EMAIL PROTECTED] alsa-driver-0.9.8]# depmod -ae
depmod: *** Unresolved symbols in 
/lib/modules/2.4.20-20.7/kernel/sound/pci/au88x0/snd-au8820.o
depmod: snd_mpu401_uart_new_Ra9ec76fd
depmod: snd_mpu401_uart_interrupt_Rff6d4aa3
depmod: snd_ac97_mixer_Rdd7e1738

By comparing the ALSA driver 0.9.8 source tree to the CVS repository at 
the OpenVortex web site where the vortex driver was developed, I found 
that there were some missing lines in several Makefiles in the ALSA 
tree.  In the OpenVortex CVS repository, these lines appear in Makefiles 
under alsa-kernel/ but my understanding is that a driver shouldn't touch 
these files until it is included in alsa-kernel/, so I added the lines 
to the corresponding Makefiles outside of alsa-kernel/.  I'm not 100% 
sure if all the dependencies I've added are necessary--I just blindly 
copied lines from the OpenVortex CVS.  Someone with a better 
understanding of the driver can double-check me.

After making these modifications (see patch below), the vortex driver 
compiled with no unresolved symbols on my system, and is working great. 
 Thanks to ALSA and the OpenVortex guys for getting my soundcard 
working without having to use the old binary-only Aureal driver.
