[parisc-linux] Harmony on 710 working?

[Christian Schmitt]

Hi,

I recently downloaded and compiled the latest pa-kernel. I also included harmony 
sound support and now I would like to know if and how I can access the sound 
device. Serching on the web was no success.

Hi Christian,
at least I got the Harmony driver working on my c110. I used the Kernel
driver first, but found out that kmixer wasn't working (obviously expected
alsa)
I could however cat *.au files to /dev/audio making a lot of sound. After
that, I compiled the alsa stuff -there are two sets of drivers, but one
didn't work as expected. I cannot look things up, currently I am on
holliday in Ireland.. You need to insmod the driver as far as I remember.
I'll be able to tell you more after the linux beer hike... ;-)

cheers

A great many Linux sound programs seem to assume that the machine is
little-endian and don't work on HP IME. mpg321 seems OK to me as is sox but
anything more serious (particularly on the recording side) tends to have
problems.

Maybe I should file some bugs in the Debian BTS.

I recompiled the kernel with harmony as a module. I get unresolved symbols when 
loading the harmony driver:

ccio_get_fake

Any suggestions?

Re: [parisc-linux] Harmony on 710 working?

I have a theory on this .... but will probably be dis-reguarded by
someone more knowledgable :)

I will try to explain what I believe the problem is, and provid a
quick hack/work around for you to get it working.


First can you tell me if CONFIG_IOMMU_CCIO is defined in your
kernel as this will affect my answer.

My suspicion is that it is not defined, thus my answer makes
this assumption.


Problem:
	The CONFIG_IOMMU_CCIO is not defined in your kernel,
	so the ccio_get_fake() is defined to be NULL in
	include/asm-parisc/pci.h.  This usually works fine
	if the drivers are compiled into the kernel ... but
	you are loading this as a module....  My suspicion is
	that the harmony module is trying to find the 
	ccio_get_fake() entry point and your kernel does not
	export that function. (CONFIG_IOMMU_CCIO is not 
	defined).

	What confuses my about this problem is why ccio_get_fake()
	is not defined to NULL by include/asm-parisc/pci.h.  Is
	there a mis-match between your kernel and module CONFIG_*
	options?


Solution:
	Since the 710 does not have ccio, the cico_get_fake() 
	is not needed. The ccio_get_fake() only needed for ccio
	machines on busses below the ccio that are not PCI (ie,
	PIC, GSC).  So for you temp hack, just assign
	harmony.fake_pci_dev to NULL.  Once we have a better
	picture of what is happening, we will insert a better
	fix if appropriate :)

Thanks,

- Ryan

harmony.c needs to include pci.h :^(

./include/asm-parisc/pci.h:#define ccio_get_fake(dev) NULL

that's where the pci_dma_xxx interface definitions live.
Or those definitions need to move to a seperate file that
harmony.c and pci.h can include. Maybe create a pci-dma.h?

I think this is right. I overlooked that pci.h was getting
included...even though we should move pci_dma* to a different
file like I suggested.

Hello,

CONFIG_IOMMU_CCIO is set to "y" in the kernel config. I set it to "n", 
recompiled the modules and "modprobe harmony" works.
However, aumix doesn't find a mixer device. Is there any way to find out where 
the problem is?

You should not have to compile the modules differently then from the
kernel.  What happens when you compile both the kernel and modules
with CONFIG_IOMMU_CCIO=y?

[Note: The ccio_get_fake will return the appropriate NULL if your
system does not have any ccio devices.]

Sorry, I don't know anything about aumix.   Do you have a /dev/mixer?
sane permissions? etc?

Thanks,

As a side note (and interesting test) this should work properly when
bot the kernel and modules are compiled with CONFIG_IOMMU_CCIO not
set either.

I believe the problem you are seeing is when the kernel is compiled
with CONFIG_IOMMU_CCIO is not set, and the modules are compiled with
CONFIG_IOMMU_CCIO=y.

Oops, I guess I missed that the model in question was a 710. 710's don't
have harmony audio. 705's & 710's have a different codec (Siemens PSB
2160) that is only capable of "telephone quality" audio, i.e. mono, fixed
8 Khz sampling rate.  There is currently no driver for this hardware.

FYI, The 720, 725, 730, 735, 750 & 755 don't have any kind of audio (although
there is a graphics card with onboard CD quality audio that was made for the
715s and 715t models that can also be put into these machines).

The 705, & 710 have the Siemens codec. The 715 is the first model with
"CD" quality audio.

A 735/99 I use has audio sufficient to play mp3's at good sound quality
using alsaplayer; I assume this is Harmony hardware.  Not part of a
framebuffer card.

i believe jsm is mistaken about the 735 & 755.  735 used the followon
chip from Asp and would surely have had the same sound abilities as the
715/Scorpio.  the harmony driver should stop claiming the 705/710 audio
though (an easy change to make).
