Summary: usx2y driver causes kernel oops
Description:
While playing a soundfile using my Tascam us-122 (Alsa Module snd-usx2y)
after a few seconds the sound stutters and i get an Kernel oops.
This is not happening if I use Jack.
I'm using the latest alsa drivers 1.0.5. With kernel 2.6.6.

As a test please replace all occurrences of GFP_KERNEL in
function snd_usX2Y_substream_prepare() with GFP_ATOMIC.
That function is in alsa-driver/usb/usx2y/usbusx2yaudio.c.

Sorry i was to fast. The old error message has gone, but after aprox. 10
min. of listening to a mp3 file by xmms (alsa plugin) the sound becomes
completely distorted. I don't if this dmesg output is alsa related:

The "ALSA......" lines are indeed ALSA-related. That issue is fixed in cvs
and shouldn't harm pcm playback.
The ACPI errors could cause distortion.
Please switch off the acpi-deamon.
Here I would do this as su with "/etc/init.d/acpid stop".
You could also use the kernel boot option acpi=off.
And yes, there will be a fix for the "Debug: sleeping function called from
invalid context" error. It will be a rearangement of some functions; more
complicated than this test-fix.

karsten - 07-01-2004 00:43 CEST

Does setting SNDRV_PCM_INFO_NONATOMIC_OPS also allow to sleep in start
callback? Don't think so, no?
usx2y support should evolve like this I think:
params_callback(){
// handle out params with userspace
}
prepare_callback(){
//actually set hardware: usbinterface for format,
//& submit some urbs to set the rate.
//AND prepare, start all needed isochronus endpoints.
//May sleep here if we set SNDRV_PCM_INFO_NONATOMIC_OPS.
}
start_callback(){
// activate interaction with alsas pcm stream.
// Don't sleep here, no?
}
stop_callback(){
// deactivate interaction with alsas pcm stream.
// Don't sleep here neither ;-)
}
hw_free_callback(){
// May sleep here.
// stop unneeded isochronus endpoints.
}
Code is all there, but currently not always in erm... their callbacks.

hi maggoi
please test with the latest version from alsa cvs.
The issue "Debug: sleeping function called from invalid context at
mm/slab.c:1996" should be solved.
Stuff should also work with an ACPI or APM enabled kernel.
To hold off buggy ACPI or APM implementations from disturbing ALSA's
operations (i.e. by disabling interrupts for too long) switch off the
relevant deamons (that's what I do here) or even boot with acpi=off or
apm=off.
To help fixing ACPI please mail to LKML.
Thanks
karsten

Summary: usx2y driver causes kernel oops
Description:
While playing a soundfile using my Tascam us-122 (Alsa Module snd-usx2y)
after a few seconds the sound stutters and i get an Kernel oops.
This is not happening if I use Jack.
I'm using the latest alsa drivers 1.0.5. With kernel 2.6.6.

As a test please replace all occurrences of GFP_KERNEL in
function snd_usX2Y_substream_prepare() with GFP_ATOMIC.
That function is in alsa-driver/usb/usx2y/usbusx2yaudio.c.
Thanks for debugging.

Thank's a lot, this has solved the issue. Will you include this fix in

Sorry i was to fast. The old error message has gone, but after aprox. 10
min. of listening to a mp3 file by xmms (alsa plugin) the sound becomes
completely distorted. I don't if this dmesg output is alsa related:

----------------------------------------------------------------------
karsten - 06-28-2004 21:04 CEST
----------------------------------------------------------------------
The "ALSA......" lines are indeed ALSA-related. That issue is fixed in cvs
and shouldn't harm pcm playback.
The ACPI errors could cause distortion.
Please switch off the acpi-deamon.
Here I would do this as su with "/etc/init.d/acpid stop".
You could also use the kernel boot option acpi=off.
And yes, there will be a fix for the "Debug: sleeping function called from
invalid context" error. It will be a rearangement of some functions; more
complicated than this test-fix.
----------------------------------------------------------------------
maggoi - 06-29-2004 10:45 CEST
----------------------------------------------------------------------
Sorry, with alsa related i meant the acpi lines. But anyway, does this mean
that the usx2y driver will not work with acpi at all? I used my tascam
us-122 under WinXP and had also issues with drop outs while acpi was
switched on.
Thanks for your efford.
----------------------------------------------------------------------
tiwai - 06-30-2004 15:44 CEST
----------------------------------------------------------------------
You can set SNDRV_PCM_INFO_NONATOMIC_OPS to pcm->info field, so that
prepare callback is called outside the spinlock. See usbaudio.c.
----------------------------------------------------------------------
karsten - 07-01-2004 00:43 CEST
----------------------------------------------------------------------
Does setting SNDRV_PCM_INFO_NONATOMIC_OPS also allow to sleep in start
callback? Don't think so, no?
usx2y support should evolve like this I think:
params_callback(){
// handle out params with userspace
}
prepare_callback(){
//actually set hardware: usbinterface for format,
//& submit some urbs to set the rate.
//AND prepare, start all needed isochronus endpoints.
//May sleep here if we set SNDRV_PCM_INFO_NONATOMIC_OPS.
}
start_callback(){
// activate interaction with alsas pcm stream.
// Don't sleep here, no?
}
stop_callback(){
// deactivate interaction with alsas pcm stream.
// Don't sleep here neither ;-)
}
hw_free_callback(){
// May sleep here.
// stop unneeded isochronus endpoints.
}
Code is all there, but currently not always in erm... their callbacks.

Summary: usx2y driver causes kernel oops
Description:
While playing a soundfile using my Tascam us-122 (Alsa Module snd-usx2y)
after a few seconds the sound stutters and i get an Kernel oops.
This is not happening if I use Jack.
I'm using the latest alsa drivers 1.0.5. With kernel 2.6.6.
