More CS4630, secondary CODEC output.

More CS4630, secondary CODEC output.

[Benny Sjostrand]

Hi again!

Seems there's quite big interest in the cs46xx stuff. Finally i've been 
able to have output from
the rear channel on the secondary CODEC. For the moment the output are 
same on both
rear and front channels, but it's possible to create a secondary .WAV 
device and
transfer two independent DMA channels to front and rear, and I believe 
that I know
how to do that, but that will require some more work and some drastic 
changes in cs46xx_lib.c.

It was not easy to find out how to probe and speak to the secondary CODEC,
it has to be done different with AC97 2.0 and AC97 1.03 codecs, on AC97 1.03
I believe that codec_write && codec_read fucntions cant be the same so 
for the moment
(probably) only cards with AC97  2.0 codecs will work. I've only tested 
this with "Hercules Game Theater",
probably there will be a lot of strange behaviours with other soundcards.

Now the "Game Theater XP" got two CS294 codecs, and now the ALSA mixer 
got two elements
of almost everything, where about a 70% of all controls in the mixer are 
probably totally meaningless,
controlling stuffs that are not conected to CODEC any suggestions about 
what to do with this ???
It dont not feel necesary to have two Master volumes ...

Heres my new snaphot, you are welcome to test it out:

    And thanks again! For anybody interested, I have the same patch that
modified to work against CVS. Feel free to ask if you want it. (it's 61k)

    And to those with Santa Cruz cards, after my first (quick) test the 
rear
channel doesn't seem to work... yet.

    Gee, thanks Benny. Just when I was getting used to the dsp_scb layout,
you change it. ;)  (though I admit it is a _good_ change)

Well, you dont seems to any luck ... no SPDIF, no rear sound -:(
Do you know which CODEC's you card have ??, are AC97 2.0 or AC97 1.03

The problem is that the secondary AC97 2.0 CODEC uses:
BA0_ACSDA2, BA0_ACCTL, BA0_ACCAD, BA0_ACCDA, BA0_CSTS2
registers, using BA0_ACCTL reigsters TC bit to address primary or 
seconary CODEC.
But seconary AC97 1.03 uses:
BA0_ACSDA2, BA0_ACCTL2, BA0_ACCAD2, BA0_ACCDA,2 BA0_CSTS2
registers to address the secondary CODEC.
(about what I can understand from the bloody spec. )

The case for 1.03 CODEC's is not implemented for the moment, I got no way
to test it.

Well, but I got yet another new problem here. the /proc/asound/card0/dsp_scb
entry is to long, and now it's not possible to view all entries, the 
last entries
(SPDIFOSCB, SPDIFISCB and AsyncCODECSCB) are cut of.
Any suggestion about what to do ??

Turtle Beach Santa Cruz boards have:

CS4630-CM DSP, 
CS4294-JO codec, 
CS4297A-JO codec

the board supports 4 analog inputs + 6 analog outputs (I use it for
multi-track recording). One thing that might cause for the driver is that it
has one 1/8" jack, the 'versa jack' that combines multiple (selectable)
functions:

- analog in (channel 3+4)
- analog out (channel (5+6)
- digital out (spdif+ac3; these are different signals on the tip/ring of the
  mini jack)

    I have been thinking about this as well. I wrote Turtle Beach 
requesting
any kind of documentation on the Santa Cruz, specifically, design docs.
Hopefully they will provide some useful information regarding this question
as well as "does S/PDIF travel through the CS4297A or is it output directly
by the CS4630?". I informed them that the Hercules Game Theater had digital
and rear channel support functioning, and that the current driver
implementation was incompatible with the Santa Cruz. Hopefully that will
spur them to release some useful docs. (I figure I might as well use the
leverage while we have it. :)

    I just recalled something that may help with this problem. Crystal
released a driver that had support for the second codec; that driver worked
fine with my Santa Cruz, so we may be able to compare the setup and find
the problem.
    I'll start looking, but if anybody else wants to help feel free. The
Crystal driver is available at:

ftp1.cirrus.com
username: ftppclink
password: cSPxQMd

    It's under the folder "cs46xx-02a-secondcodec". Also, there's another
datasheet available that was previously on that FTP site, but has recently
been removed. If anyony would like a copy, you can e-mail me for one. It
contains very useful documentation on the CS4630.

With the new PCM multi channel support, I believe  there no way
to have the support for the old image,  to many changes in cs46xx_lib.c now
hardly depends on the new stuff.
So if we want to still support the old code i think the only way is to 
create
a new directory  alsa-driver/pci/cs46xx_old/_new, having to independent
cs46xx drivers.
But I hope that in some near future we can discard the old cs46xx.
Of course that we must be sure it work at least so good as before with all
known CS46xx soundcards before discarding anything.

Well, i got some more work to do. I will try fixup my new code changes 
so it follows
the coding-style used by ALSA, and then become mergable with current CVS.
(and you dont have to do all thoose indentation fixes again)

I merged your codes into the cvs.
The codes are almost identical except for small bugfixes,
re-indentation, and replacement of debug printing.

To be sure, the old dsp image is still chosen unless
CONFIG_SND_CS46XX_NEW_DSP is set to yes.
For compiling the new dsp image, please remove the comments in
alsa-driver/pci/cs46xx/Makefile.

The driver seems working on TerraTec DMX XFire.  The status is:
- OK: The first codec
- OK: SPDIF playback (audio)
- NG: SPDIF AC3 (non-audio)
- NG: The secondary codec, not detected.


Anyway, thanks for your work!

Please send patches againt cvs if you modify the driver more, so that
I can commit it soon.


ciao,

Takashi

i'm now merging the new stuff.  let's see what happens.

yes.  if the new driver is confirmed to work on most of machines
(cs46xx is used on many notebooks), then we can obsolete it.

the coding-style of ALSA is not particular except for its naming
rule.  we followed the standard kernel coding style.

as said, i'm now managing to merge the 0731 stuff.
just a moment...

finished.  now committed to cvs.

the old driver is still integrated into the same source.
the number of ifdefs increased, so more clean-up's will be necessary,
though.


about the secondary codec on terratec xfire: it's still not detected.
could you test the latest cvs driver?  i'm afraid that i did something
wrong in merging...

My quick look on the cvsweb everything looks just fine, just one small 
critical
fix that I missed in my 0731 release, I believe that's easy commited to 
CVS (see my notice about this
earlier today) in _dsp_unlink_scb() function:

Any change from now
will be  based on the CVS.
About the secondary CODEC, 1.03 codecs are not supported with the 
current code, read, and write fucntions
needs to be slightly different for 1.03 codecs. I believe there are very 
few cards shipped with 1.03 codecs, dont know the case
with terratec.
All differents boards always are shipped with some dam GPIO controls 
which you never knows where they are wired, which never are documented, 
if the terratec board is shipped with 2.0 codecs and it's not detected I 
believe it's some magic GPIO pin that we need
to turn on.

I've done a quick test with the CVS code now, and it seems to work just 
fine, i just got some newbie
questions,  how do activate CONFIG_SND_CS46XX without modifying the 
Makefile?, how do
I activate the snd_printd ? , (without modifying config.h)

About the secondary codec on the terratex xfire card, can we try to 
trace exactly where it failed
to detect it, I would like to know.

On the "Turtle Beach Santa Cruz" now i know that GPIO7/GPIO8 on sec. 
codec controls back speakers, that's not done yet,
But I would like to know if current code at least detects the secondary 
CODEC successfully. In theory it should.

I would like to build a list with card and of DSP and codec (only cs46xx 
cards), please helpme to complete this list.

Hercules Game Theater XP
dsp: cs4630
primary codec: cs4294
secondary codec: cs4294
EPGIO2 controls ext. amplifier

Turtle Beach Santa Cruz
dsp: cs4630
primary codec: cs4294
secondary codec: cs4297A
GPIO7/GPIO8 on secondary codec controls back speakers support

Terratec XFIRE:
dsp: cs4630
primary codec:  ????
secondary codec:  ????
????

....


A small fix to cs46xx_lib.c, it does not make any sense calling 
playback_transfer before the PCMreader is linked or Playback controll 
register set to 0. && I would like to update the TODO text to something 
else.

if you build the modules from alsa-driver (i.e. not on 2.5 kernel),
then CONFIG_SND_CS46XX is set in the configure script.  as default,
all card modules are compiled, or selectable via --with-cards option.

but the CONFIG_SND_CS46XX_NEW_DSP variable is not set in configure
script.  you have to modify it in alsa-driver/pci/cs46xx/Makefile.
you'll see the two lines which are currently commented out.
if this is extremely annoying, i will enable it as default, but i
don't think it's too much job :)

abound snd_printd() and snd_printdd().
the former is activated when --with-debug=full option is given to the
configure script.  and the latter is on when --with-debug=detect.
the latter option enables all debug information.

perhaps X-Fire has also some gpio's.  i'll try to contact with
TerraTec about this info.


Terratec X-Fire:
dsp: cs4630
primary codec:  CS4294 rev 5
secondary codec:  not sure.. the driver shows 'not present'
     i will take a look at the card later

    Actually, the codecs are reversed. The CS4297A is the primary codec, 
and
the CS4294 is the secondary. And yes, your driver detects them both just
fine and I can manipulate both with alsamixer and confirm the changes to
the CS4294 with the changes in the "ac97#0-1regs" file in 
/proc/asound/card0.
