success in building agrsm for ubuntu karmic

[webkitdev]

All,

I have been able to build and load agrsm for Ubuntu 9.10 dev release
(kernel 2.6.31-13-generic). I could load the kernel modules, but would
like to know how to test if my modem works. I do not have a PPP dialup
account as of now. Can some one please suggest on how to test this out
and what features would work?

Regards,
Shaji

First thing, try wvdial
There are two steps.
After loading the module, do    sudo  wvdialconf  /etc/wvdial.conf
If it finds the modem, your success is great.
Then edit the file /etc/wvdial.conf

There are three lines starting with a ;  (semi colon). In these 3 lines:
Remove the ;
Remove the <
Remove the >
Modify the phone line  to    Phone =  1234567    but replace 1234567 by
a phone number close to you so that you can hear it it rings.
Make sure that there is a line
Carrier Check = no
in the file.
Save and exit the editor.
Now,  just try    sudo wvdial      and listen if the dialled phone
number rings (no sound from the modem; be enar that phone number or ask
somebody to listen for you, a friend probably.

If the dialled number rings, this is a very great step ahead.

In which country/city do you live? Needed to try to find a free service
nearby.

Thanks Jacques.

Using wvdial, I am getting a kernel OOPS.. will look at this more
closely ..

There are three (at least) different agrsm code packages, for the
various Agere chipsets.
Please run scanModem and send us the ModemData.txt output, to more
precisely identify your chipset.
There are alternate ALSA drivers for some Agere/LSI chipsets.
Which code package  did you use to compile your driver??
An alternative may evade your problem:

Thanks Marvin.

Below is the scanmodem output.

I have downloaded the agrsm from :

http://linux.zsolttech.com/linmodem/agrsm/Testing/dkms-agrsm_2.1.80-9mdv2009.0_i386.deb

I have made minor fixes to get it compile with 2.6.31.

Please let me know if you see something interesting or you need more
information.

Shaji

Support type needed or chipset: agrsm


The AgereSystems/LSI agrsm code supports compiling of a agrmodem +
agrsm driver pair.
One resource site is
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/
Thereat get the agrsm_howto.txt and one of the agrsm-tools packages.
The initial agrsm_howto.txt compiling steps are only cogent to modems
with PCI IDs:
   11c1:0620, 11c1:048c and 11c1:048f chips.
   They use the agrsm-20090418.tar.gz package.
The agrsm-tools sets a useful symbolic link and a agrsm-test utlity

For AgereSystems/LSI with Vendor 11c1 chips hosted on High Definition
Audio cards, there may be support
through the agrsm resources (providing an agrmodem + agrserial driver
pair) as an alternative to usage
of the snd-hda-intel driver + slmodemd helper. For the 11c11040 modem
chip, ONLY the agrsm code is competent.
Your Linux distro's dkms package should be first installed, as it
directs the installation of modem
specific dkms-agrsm resources, and also directs auto-installation of
new drivers upon kernel upgrades.

Currently, the dkms-agrsm code is NOT competent for 2.26.28 and later
kernels.
A short term fix is to install linux-image + linux-headers packages for
earlier kernels.
For detailed instructions for Ubuntu Jaunty with 2.6.28 kernels, see
http://linmodems.technion.ac.il/bigarch/archive-nineth/msg01316.html

The primary dkms-agrsm resource site is
http://linux.zsolttech.com/linmodem/agrsm/
whereat a few different packaging types are available. Debian type
installers (supporting Ubuntu too)
are copied to
http://linmodems.technion.ac.il/packages/ltmodem/11c11040/ . Thereat
the current package
is the dkms-agrsm_2.1.80-6_i386.deb is for Agere/LSI chipsets hosted on
High Definition Audio cards.
Read the Modem/DOCs/Agrsm.txt for details.

 Completed candidate modem analyses.

 The base of the UDEV device file system is: /dev/.udev

 Versions adequately match for the compiler installed: 4.4.1
             and the compiler used in kernel assembly: 4.4.1



 Minimal compiling resources appear complete:
   make utility - /usr/bin/make
   Compiler version 4.4
   linuc_headers base folder /lib/modules/2.6.31-13-generic/build

  However some compilations and executable functions may need additional
files,
  in the FileNames.h (so called kernel "h"eaders) collection installed
in  /usr/include/ .
  For martian_modem, additional required packages are needed. The also
required headers of package libc6 are commonly installed by default.
  Compiling hsfmodem drivers does require linux-libc-dev and libc6-dev
packages, for kernels 2.6.24 and later versions.
  In not included on your install CD, search for them at
http://packages.ubuntu.com
 or comparable Repository for other Linux distros.
 When compiling ALSA drivers, the utility "patch" will also be needed.




If a driver compilation fails, with message including some lack of some
FileName.h (stdio.h for example), then
Some additional kernel-header files need installation to /usr/include.
The minimal additional packages are libc6-dev
and any of its dependents, under Ubuntu linux-libc-dev

If an alternate ethernet connection is available,
$  apt-get update
$  apt-get -s install linux-kernel-devel
will install needed packages.
For Debian/Ubuntu related distributions, run the following command to
display the needed package list:

Otherwise packages have to be found through http://packages.ubuntu.com
Once downloaded and transferred into a Linux partition,
they can be installed alltogether with:
$ sudo dpkg -i *.deb

There are three (at least) different agrsm code packages, for the
various Agere chipsets.
Please run scanModem and send us the ModemData.txt output, to more
precisely identify your chipset.
There are alternate ALSA drivers for some Agere/LSI chipsets.
Which code package  did you use to compile your driver??
An alternative may evade your problem:

Shahji,

dkms-agrsm_2.1.80-9mdv2009.0 is the correct package for your 11c11040
Agere/LSI chip mdem.
What were the "minor fixes" you applied?

Zsolt had remarked to me concerned this last update of this code:
There was not realy big changes, important are the alsa structs have to match
the  agrsm's  for autoload of the module, new alsa version provide an
module_alias extension
for codecs macro.  I think:
MODULE_ALIAS("snd-hda-codec-id:11c11040");
should do the job.

I have not coding depth myself

Marv,

Here are the changes that I had to make. (along  with all patches in
patches directory).

Which file should I modify for MODULE_ALIAS?

Subject: Re: success in building agrsm for ubuntu karmic










Shahji,

dkms-agrsm_2.1.80-9mdv2009.0 is the correct package for your 11c11040
Agere/LSI chip mdem.
What were the "minor fixes" you applied?

Zsolt had remarked to me concerned this last update of this code:
There was not realy big changes, important are the alsa structs have to
match
the  agrsm's  for autoload of the module, new alsa version provide an
module_alias extension
for codecs macro.  I think:
MODULE_ALIAS("snd-hda-codec-id:11c11040");
should do the job.

I have not coding depth myself
