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

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.

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?

Lee

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.
Steve

The irq problem is likely related with ACPI.

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.

PATCH 1/1 mm/slab.c : prefetchw the start of new allocated objects

[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.

+	prefetchw(objp);
 	return objp;

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 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.
Quoted 15 lines
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.
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.
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.
Quoted 8 lines
I don't have to do this with 2.4.27, anybody know why?

Perhaps you could send the `dmesg -s 1000000' output?
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.
Diff between dmesg output from step 1 and step 3

Any ideas would be appreciated.

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

In reply to 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
