Those functionality limitations in open source modem drivers are just
"unimplemented yet" stuff. The final goal is to replace proprietary
slamr driver completely.

No, I meant the 'slamr' kernel driver module, which is
built from a big binary-only library (amrlibs.o) and
a small amount of kernel glue source code. As long as
amrlibs.o is distributed only as a 32-bit x86 binary,
I won't be able to use it with a 64-bit amd64 kernel.

slmodemd is not the problem since an amd64 kernel can
support 32-bit x86 user-space binaries.

This is exactly that was discussed - 'slamr' is going to be replaced by
ALSA drivers. I don't know which modem you have, but recent ALSA
driver (CVS version) already supports ICH, SiS, NForce (snd-intel8x0m),
ATI IXP (snd-atiixp-modem) and VIA (snd-via82xx-modem) AC97 modems.

Are these all motherboard-chipset modems, or is there such a thing as an 
AC97-based PCI modem card?

Such modems also exist (AC97 controller + MC97 codec + DAA), but less
popular (especially with laptops there modem are mostly used).

I have one such built in in my Dell Inspiron 8200, which is why 
I'm following this thread with particular interest.

The strange thing is that under Windows the modem is configured 
as a Conexant thingie ... or is the problem that I have both 
and the Conexant thingie is the one connected to the actual 
modem plug? Is there a way to know this (other than having a 
look inside my laptop, that is)?

If it looks like this:

00:1f.6 Modem: Intel Corp. 82801CA/CAM AC'97 Modem Controller

it is most likely on-board south bridge and MDC (or other riser)
modem. This may work with ALSA.

Or send me your lspci.

OTOH, ALSA in 2.6.5 doesn't like the modem controller:

Not sure that last one is ALSA related. As noted in mesg 'request_irq' fails.

Yes. And it is indeed the Conexant modem seen by Windows.

Ok, I found the reason of the latter failure: in 2.6.7 I have 
ISA-PnP enabled (not in 2.6.5) and this loads the parport 
driver before the sound driver. parport steals the IRQ.

Module loading order is important: if I load the i8x0 sound 
modules first, the messages are more or less the same as the 
ones in 2.6.5 (including the "MC'97 1 converters and GPIO not 
ready" message), and then parport accepts IRQ 7 to be taken by 
resorting to polled operation:

> parport: PnPBIOS parport detected.
> parport0: PC-style at 0x378 (0x778), irq 7, dma 1 [PCSPP,TRISTATE,COMPAT,ECP,DMA]
> parport0: irq 7 in use, resorting to polled operation

I wonder what this means, and if something can be done about it 
(like: can the i8x0 sound modules use some other IRQ?)

I don't know really, but suppose that parport does not accept irq sharing.

This one is more interesting, probably special patch is necessary for conexant codec, let's see.

Please report bug to alsa and attach there output of 'lspci -vv' and tar of '/proc/asound' directory (or send to me).

Let's detach from linux-kernel list - things become pure-ALSA related.

Thanks,
Sasha.

That's an interesting idea.  Some thoughts I'd have off the bat:

- I don't think there's a software modem implementation (free or
   otherwise) for linux that can support the server side of a digital
   (v.90, v.92) connection, but that would be excellent to have

- Americans might have an FCC concern due to power output restrictions on
   digital modem protocols, and also other voice applications

- Presumably it would only make sense to do this with voice connections

- Could this idea be extended to analog telephony devices?

That'd be even better, yes -- but I was thinking of v.34.
Even having just v.29 (fax) would be nice.

You can already use the Linux ISDN code in 'voice modem' mode and do
what you like with it... what would concern them more?

Indeed.

Ideally, it could be extended to analogue coupling using standard

I mean e.g. those PBX-like device things (like the Quicknet thing maybe?) 
that let you run a telephone network in your facility, so you could hook 
up fax machines or modems to them in a 'POTS emulation' kind of sense.

One way that would work is to make the binary parts of your driver run
in user space and let the kernel part just provide a kind of simple
sound card.  The later should be much easier to free.

Modern CPUs are usually fast enough that the additional latency
caused by this doesn't matter.

The 64bit kernel can run 32bit programs without problems.

It is done so - user space daemon (with binary part) interacts with ALSA
drivers.

There was such approach, but seems it was wrong.

This should be possible (don't check yet). But the problem here was
that AMD64 machines are usually based on non-Intel chipsets
(VIA, NVidia), supports for those chipsets were added to ALSA just in
last days. Now it may be tested with recent version of ALSA.

Ok, thanks for the correction.

What's the problem exactly - your kernel part is still binary only?

One small issue is that when you have custom ioctls there may 
be some need to add them to the compat layer, otherwise the user
space part cannot issue them. This could be even done in a separate 
module from your driver though.

Current binary kernel part (slamr) is not a problem - it may be removed,
then ALSA drivers will be finished. But user-space program still have
binary code and there is no replacement.

I hope you succeed with open-sourcing all of slmodem's driver
code. My Targa Athlon64 laptop has the AMR thingy and the
32-bit x86 binary only slmodem driver prevents me from using
the modem while running a 64-bit kernel.

You mean to GPL user-space program slmodemd?
I think it is good idea, but unfortunately this code is not just my, and
final decision was 'no'.

Droping in. :)

Kernel part is not required, slmodemd works with the snd-intel8x0m Alsa 
driver. For me at least, and for the PCI version.

dear linux kernel people,

i was staggered to find that swansmart (smlink.com) have a GPL
driver for their smart usb 56k modem.

they also do a pci version: their download supports both (usb+pci)

they also provide an AC97 ALSA driver (patch is against 2.6.0)

this PCI ALSA driver is based on the i8x0 / MX 440 modem driver,
by Jaroslav Kysela <perex@suse.cz>.

all their code is GPL.  this is very cool.


it is available here:

	http://www.smlink.com/main/down/slmodem-2.9.9.tar.gz

i trust that someone will download, check it, and if
appropriate, incorporate it into the mainstream linux kernel.

the swansmart usb 56k modem is dirt cheap (it was available in
the uk six months ago for about £9), and is extremely popular
in australia and the far east.

The ALSA bit is already in the kernel at sound/pci/intel8x0m.c, I don't
know when it was added though. Not sure of the status of the USB bit,
but I think it is normally up to the author to submit something rather
than some 3rd party...

Unfortunately the ALSA driver doesn't work for me, I just get NO
DIALTONE and the following in the kernel logs:

        codec_semaphore: semaphore is not ready [0x1][0x300300]
        codec_write 1: semaphore is not ready for register 0x54
        
I only tried it out last night, and I don't really need the modem in my
laptop much (it never really travels much further than the sofa :) so I
haven't really investigated much.

The laptop is a VAIO from several years ago. lspci shows the modem as:
0000:00:1f.6 Modem: Intel Corp. Intel 537 [82801BA/BAM AC'97 Modem] (rev 03)

Most of their code is not GPL'ed. It does have a COPYING file, but that
looks like a BSD license to me. The only (implicitly) GPL'ed part is
the ALSA patch.

It's not a GPL driver, the kernel part contains a binary object file
(drivers/amrlibs.o) so I don't see how it can be included in the main
kernel tree. OTOH, at first glance only the PCI driver needs that
binary blob, the USB driver doesn't.

 ah ha!

 i sent them a message, see if they react well to licensing the
 rest as GPL.

It's mostly GPL'ed, but there are binary-only objects both in the
user-mode daemon (modem/dsplibs.o) and in the kernel driver
(drivers/amrlibs.o). 

The good news is that there a completely GPL'ed, source-complete
driver already in the 2.6 kernel, sound/pci/intel8x0m.c, which will
work with the user-mode daemon found in the smlink.com distribution.
This driver doesn't have all of the functionality of slamr driver
(which requires the propietary, binary-only object file) --- most
notably, ATM1 doesn't work when using the completely open-source
intl8x0m driver.  However, it does work just fine, and so as long as
you don't mind using the propietary object file in user-space, it's a
great solution.  I've been using the smlink daemon with both the
open-source and partial-propietary driver, and both work just fine on
my T40 laptop.
