2.6.12 sound problem

2.6.12 sound problem

[Stephen Clark]

Hello List,


I recently upgraded my laptop, HP Pavilion N5430, from a 2.4.21 kernel
to 2.6.12. As a result of
doing this my sound no longer works correctly. It plays the same thing
repeatedly some number
of times - if it plays at all.

Any ideas on how to debug this would be appreciated.

Additional info I don't see any interrupts in /proc/interrupts for the
Allegro which is on int 5.
I just tried the same laptop with knoppix and a 2.4.27 kernel and sound
works great and I do
see interrupts for Allegro on int 5.


Thanks,
Steve

So the same ALSA driver works on 2.6 but fails on 2.4?  Or are you
really saying 2.4 + the OSS driver works and 2.6 + ALSA does not?

Hi Lee,

Sorry for the confusion - the sound driver with kernel 2.4.27 works - it
looks like it is oss ( it is a
german knoppix cd and I don't parse german ), there is no /proc/asound
directory. Also I dont
have to provide acpi=off pci=noacpi,usepirqmask with the knoppix cd, but
I do when I boot the
2.6.12 kernel.

on 2.4.27 the kernel modules for sound are:
soundcore, ac97_codec, maestro3


so i am saying:

  2.4 + the OSS driver works and 2.6 + ALSA does not.

Thanks for the response.

The irq problem is likely related with ACPI.
Try to boot once with pci=noacpi.

Hi Takashi,

I have boot the 2.6.12 kernel with acpi=off pci=noacpi,usepirqmask or I
get a panic or a hang.

I don't have to do this with 2.4.27, anybody know why?

It's just really awful that 2.4 simply worked and 2.6 requires a sprinkle
of obscure kernel parameters.  I shudder to think how long it took you to
work them out.

Perhaps you could send the `dmesg -s 1000000' output?

[PATCH] mm/slab.c : prefetchw the start of new allocated objects

[Eric Dumazet]

[-- Attachment #1: Type: text/plain, Size: 549 bytes --]

[MM] slab.c : prefetchw the start of new allocated objects

Most of objects returned by __cache_alloc() will be written by the caller,
(but not all callers want to write all the object, but just at the begining)
prefetchw() tells the modern CPU to think about the future writes, ie start
some memory transactions in advance.

Some CPU lacks a prefetchw() and currently do nothing, so I ask this question :
Should'nt make prefetchw() do at least a prefetch() ? A read hint is better than nothing.

Sounds sensible enough..  slab does try to make sure it returns the
most-recently-freed object, so it's probably in cache already.  But in the
situation where we're allocating and using a lot of objects in succession
it might help.

Don't think so.  I was once told that if the cacheline is in local cache
for reading and the CPU decides to write to it, additional work is needed
for the write so the prefetch-for-read didn't buy you anything.

the idea is good, but i'd suggest to do the prefetchw a bit earlier, 
right where we calculate objp. Furthermore, it might make sense to only 
trigger the prefetchw in the alloc-miss (non-per-CPU cache) case. There 
it's almost surely a win, in the per-CPU cache case it's not always.

This is not true, especially on SMP.  If the only prefetch variant
available does a "prefetch for read", the cpu will only grab the
cacheline in shared state if other cpus have a dirty copy.

And, as a result, when the write to the cache line occurs yet
another bus transaction will go out in order to get exclusive
access to the cache line on the local cpu.  This is extremely
inefficient.

So it's better in this case to make no prefetch, and thus only
incur one bus transaction when the memory access occurs.

Hi Andrew,

Thanks for the response.

I found a better solution to my problem with my HP N5430 laptop over on 
the alsa-devel list, my sound had quit working also. The new
solution, which was pointed out to me by Henry Yuan was to boot with 
lapic. I had noticed in the dmesg output that a lapic existed but was 
turned off by the bios, and a pseudo local apic was being used, this 
caused problems with APCI and my sound.

If you would still like the dmesg I would be glad to send it.

Hello Andrew

My joy was short lived - but I do have more info.

1) If I cold boot with only 'lacpi' to run level 3 - shortly after I get 
the login prompt the laptop freezes.

2) If I cold boot with 'lacpi  acpi=off  pci=noacpi,usepirqmask'  the 
system boots and does not freeze but  when I try to play sound I get no 
interrupts from my sound card.

3) If I now warm boot from step  2 with only 'lacpi' my  laptop seems to 
be stable  and I have sound.

I did this several times to try and really verify the above scenarios.

Hello List,

I have compiled 2.6.13rc4 and am still having the problem described above.

What is the best way to debug a hang? I there a way to turn on verbose 
debugging at boot? Also why would
the hardware capabilities be different between a cold boot and a warm boot?

Thanks for any advice,
Steve

2.6.13rc4 hang

[Stephen Clark]

Hello List,

I am having a problem 2.6.13rc4 described below on a HP Pavilion N5430 
laptop.


1) If I cold boot with only 'lacpi' to run level 3 - shortly after I get
the login prompt the laptop freezes.

2) If I cold boot with 'lacpi  acpi=off  pci=noacpi,usepirqmask'  the
system boots and does not freeze but  when I try to play sound I get no
interrupts from my sound card.

3) If I now warm boot from step  2 with only 'lacpi' my  laptop seems to
be stable  and I have sound.

I did this several times to try and really verify the above scenarios.

Diff between dmesg output from step 1 and step 3

2.6.12 sound problem

[Stephen Clark]

Hello,

I recently upgraded my laptop, HP Pavilion N5430, from a 2.4.21 kernel 
to 2.6.12. As a result of
doing this my sound no longer works correctly. It plays the same thing 
repeatedly some number
of times - if it plays at all.

Any ideas on how to debug this would be appreciated.
Thanks,
Steve
