[PATCH]snd-usb-usx2y 0.7.1 against cvs head: please test it!

Hi,

this module version sports "no sleeping" in ALSA's pcm START/STOP callbacks.
It could need a little more testing, as the changes are many.
Here it works well with kernels "planet CCRMA's 2.4.26" and "vanilla 2.6.7 all 
debug flags I found enabled".

Thanks & regards,
Karsten

P.S.: Please ignore the previously postet "[PATCH]snd-usb-usx2y 0.7"

Applied to cvs.  Thanks.

Just built from cvs against a custom 2.6.7-cko6 kernel on a SUSE 9.1
SMP/HT box, and assured that the patch is already applied.

Erm... I get the following while modprobing snd-usb-usx2y:

WARNING: Error inserting snd_hwdep
(/lib/modules/2.6.7-cko6.0smp/kernel/sound/acore/snd-hwdep.ko): Unknown
symbol in module, or unknown parameter (see dmesg)
FATAL: Error inserting snd_usb_usx2y
(/lib/modules/2.6.7-cko6.0smp/kernel/sound/snd-usb-usx2y.ko): Unknown
symbol in module, or unknown parameter (see dmesg)

Then the relevant dmesg says:

snd_hwdep: Unknown symbol snd_kcalloc
snd_usb_usx2y: Unknown symbol snd_hwdep_new

So I guess something went wrong on my snd-usb-usx2y build. OTOH, the
onboard snd-intel8x0 based is loaded and working without a glitch.

So, too pity I can't get my us224 onto the testing right now.

Any ideas?

Did you run cvscompile?  configure script must be regenerated.

Yes, I've ran ./cvscompile. My steps were just the following:

  cvs co alsa-kernel
  cvs co alsa-driver
  cd alsa-driver
  export ALSAKERNELDIR=../alsa-kernel
  ./cvscompile
  su -c "make install"

Something wrong?

Should be ok.

snd_kcalloc() is an obsolete function which was replaced recently with
kcalloc().  I guess the modules are not installed correctly, or the
detection of the kernel verion was wrong.

Checkout alsa-tools and rebuild your usx2yloader

OK. It was something I've screwed up. A second 'make install' and
everything is up and running on my US-224, at least as it was before.

JACK seems to work fine, and MIDI also gets it thru. So chalk one for
US-224 and 2.6.7-cko6.

Anything I should check deeper?

snd-usb-usx2y 0.7.1 against cvs head: please test it!

If you didn't try yet,
please start Jack with the -S alsa driver option to use 16bit format.
Using 24bit on kernels with "uhci debugging" I get lots of dmesg warnings 
complaining about overusing the usb - bandwidth although everything works 
fine. Using 16bit the kernel doesn't complain.
Maybe usb bandwidth checks are broken?

starting jackd with -S (force 16bit format) works!

but only for about 20 minutes, then jackd dies with same error, same

if your kernel is currently configured with CONFIG_USB_BANDWIDTH=y
(and you like to spend some more time testing):
Please recompile the kernel without that option and retry.
the relevant part of the .config would look like:
>>>>>>
#
# Miscellaneous USB options
#
CONFIG_USB_DEVICEFS=y
# CONFIG_USB_BANDWIDTH is not set
# CONFIG_USB_DYNAMIC_MINORS is not set
<<<<<<

without USB_BANDWIDTH enabled all works fine now! I tested JACK with
period size 144 / 2 buffers / 24 samples and it now works very stable.

No problems on debian with 2.4.25-rc1 using an us122 :)
