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).

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.

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?

[Ryan Bradetich]

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

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?

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

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,

- Ryan

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

[Ryan Bradetich]

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.

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?

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

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

Juergen

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.
