Issues with HDSPM

Issues with HDSPM

[Andre Schramm]

Hello,

the HDSPM driver seems to be broken in the current ALSA release.
We're using CentOS 5 with 2.6.33.9-rt31.64.el5rt and ALSA 1.0.24
compiled from source, the card is a PCIe Hammerfall DSP MADI (rev d2).
As already mentioned in [1], the card operates in master mode, but the
system clock mode can't be set to anything higher than 48kHz.

  : values=48000


When switching to a PCI version of the card, the kernel completely
crashes on boot.

And with [2], there is another issue which unfortunately hasn't been
merged yet and still exists in the current release.

Unfortunately, I don't happen to have a MADI card, but Fredrik has.
Fredrik, can you confirm the problem?

At least my RayDAT can be perfectly set to all sample rates via
alsamixer, and the code for setting sample rates isn't device specific,
so I'd expect it to work on MADI, too.

We'd need a crash report. Best is to blacklist the kernel module, boot
the machine and then trying to load the module, maybe on a console.

If need be, we can meet and fix the problem on-site, I'm living close to
your place.

Could you try this patch? (for your convenience, I've also attached it)

I just noticed that the driver in the 1.0.24 release tarball doesn't
contain the latest fixes we already have in the git repo.

I reckon the PCI version has an "unknown" revision ID. We added a
default case a couple of month ago to prevent the kernel from crashing:

	default:
		snd_printk(KERN_ERR "HDSPM: unknown firmware revision %x\n",
				hdspm->firmware_rev);
		return -ENODEV;
	}

I suggest you use this file instead of the 1.0.24 tarball:


http://git.alsa-project.org/?p=alsa-kernel.git;a=blob_plain;f=sound/pci/rme9652/hdspm.c;hb=HEAD

If you send me the revision ID of your PCI MADI card, I'll come up with
a patch.

confirmed with 2.6.39.

this is a regression iirc, i think it used to work in 2.6.37...

adi, i can test patches if you want, or you can have ssh access if it helps.

Very likely, the code between 2.6.38 and 2.6.39 changed more or less
completely.

ssh would be good. Together with Andre, it might be worth checking
on-site that the resulting sample rate is indeed correctly reported by
external equipment.

Andre, JFTR: don't use hdspmixer from the tarball, go directly for the
git repo (alsa-tools) until 1.0.24.2 is released.

for the record, we just worked on my machine, and the problem could not 
be reproduced again. what i think happens is:

* when you go higher than 48k, the card reduces its channels count, 
first to 32, and then, above 96k, to 16 channels i/o.
* when something is using the card, this reconfiguration might be 
prevented, so the card refuses to increase the sample rate.

i can switch to 192k no problem, but if i start jack while at 48k, i can 
only go down, not up. my guess is that i had a half-dead jack around 
when i tried to reproduce your issue. andre, can you confirm you do not 
have any processes running on the card when the problem occurs? i guess 
lsof /dev/snd/* might be useful...

best,


jörn

There's an easier way to acquire this information:

   $ cat /proc/asound/default/pcm0*/sub0/status

If it reads "closed", then nobody is using the card, otherwise, there
would be an entry for owner_pid, thus preventing the card to change
clock modes outside the multiples of 32/44.1/48 (*1, *2 or *4 depending
on SS/DS/QS).

I will have access to the hardware again on Friday, I'm going to provide
some more details then. I was trying to set up a kdump environment, but
haven't been doing much kernel hacking yet.

That would be great, we're heavily using the MADI cards. But maybe we
can figure it out online.

Thanks. A colleague of mine found this one and we used to patch it by
hand till now. But it would be great if this would go upstream. :)

I wouldn't swear it, but I'm fairly sure no one was using the card.
I'll check on Friday and get back to you.

Everything was reported as CLOSED. I tested again with 3 cards in
combinations of 2 (2x PCI and PCI and PCIe mixed), the results are
attached. Setting the rate on the PCIe card worked fine, but the PCI
versions reported bogus rates.
I built ALSA again from the sound-2.6 tree Adrian pointed me to with
the latest hdspm.c. One of the PCI cards had 205 as firmware revision,
I added it acc. to [1] as HDSPM_MADI_OLDEST_REV, which made the module
work for the card.

 Andre
