Based on the Python scripts in this repo, I created a merge request to add support for the XMM7360 in RPC mode to ModemManager: !1200 If anyone here has capabilities to test my implementation on their setup, please do and report about your experience in the MR. Thanks in advance!

Will do! Tomorrow will be a good time for testing.

Can you explain how to test it ? Ubuntu 24.04 LTS

tuxor1337 commented 3 months ago

I don't have Ubuntu. But here is how I test it under Fedora 40, and it should be the same under Ubuntu:

  1. Install the build dependencies: 
    $ # for Fedora
$ sudo dnf builddep ModemManager libmbim
$ 
$ # for Ubuntu
$ sudo apt build-dep modemmanager libmbim
  2. Clone the ModemManager and libmbim git repositories and check out my branch: 
    $ git clone https://gitlab.freedesktop.org/mobile-broadband/ModemManager.git/
$ git clone https://gitlab.freedesktop.org/mobile-broadband/libmbim.git/
$ cd ModemManager
$ git fetch https://gitlab.freedesktop.org/tuxor1337/ModemManager.git/ port-xmm7360
$ git checkout -b 'ModemManager-port-xmm7360' FETCH_HEAD
  3. Configure and compile libmbim: 
    
$ cd ../libmbim
$ meson setup build --buildtype=debug --prefix=$PWD/dist/ 
$ ninja -C build install

for Fedora

$ export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:$PWD/dist/lib64/pkgconfig" $ export CFLAGS="-I$PWD/dist/include/libmbim-glib" $ export LDFLAGS="-L$PWD/dist/lib64"

for Ubuntu

$ export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:$PWD/dist/lib/x86_64-linux-gnu/pkgconfig" $ export CFLAGS="-I$PWD/dist/include/libmbim-glib" $ export LDFLAGS="-L$PWD/dist/lib/x86_64-linux-gnu"

4. Configure and compile ModemManager:

$ cd ../ModemManager $ meson setup build --buildtype=debug --prefix=$PWD/dist/ --sysconfdir=$PWD/dist/etc -Dudevdir=$PWD/dist/lib/udev $ ninja -C build install

5. Stop and Disable ModemManager with the following commands:

$ sudo systemctl stop ModemManager.service $ sudo systemctl disable ModemManager.service

6. Make sure the `iosm` kernel module is loaded. NOTE: You do not need any of the stuff from this GitHub repository. You don't need the xmm7360-pci kernel module, or the Python scripts.

$ sudo modprobe iosm

7. Run ModemManager in debug mode:

$ sudo ./build/src/ModemManager --debug


8. Set up a broadband connection with NetworkManager. Disable Wifi (and LAN) check whether you are connected to the internet with your broadband modem, e.g. by opening some websites.
9. If it doesn't work for you, make sure to give it another try after a fresh reboot of your computer because your previous setup might have screwed up your modem device.

Go to https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/1200 and report about your experiences. Note that some things are known not to work. See the first post of the merge request for more information about what is and is not expected to work.

Done, works nicely!

pswiatki commented 3 months ago

$ export PKG_CONFIG_PATH="$PKG_CONFIG_PATH:$PWD/dist/lib64/pkgconfig"

Note (to testers): check the path - it may be slightly different. My build (of libmbim) created ./dist/lib/ (not ./dist/lib64/)

I would like to share my situation, unfortunately I can't get it to work though. I'm working on a X1 Carbon Gen 6, Ubuntu 24.04, all firmware / Bios updated. The Fibocom L850-GL works under Windows 11 without issue. After a clean reboot the Modem is in a 'failed' state with failed-reason "sim-missing". After installing the patched ModemManager (which appears to work well) I'm no longer getting any Modem in ModemManager. The debug output is this:

ModemManager[6306]: <msg> [1721982321.580557] [device /sys/devices/pci0000:00/0000:00:1c.2/0000:03:00.0] creating modem with plugin 'Intel' and '4' ports

I'm happy to take any pointers / or to try additional steps if I can help this effort. Kind regards, Stefan

Most likely, your modem device is in a frozen state. Make sure to completely disable any older version of ModemManager that you might have on your system. For example systemctl disable ModemManager.service. An older version of ModemManager will try to interact with the modem device and might put it into a dead frozen state. Make sure to not only reboot the computer, but really shut down and boot again (cold boot), before trying to use the new version of ModemManager.

Missing step for ubuntu 24.04:

sudo apt install libglib2.0-dev libgirepository1.0-dev help2man meson build-essential libdbus-glib-1-dev libgudev-1.0-dev libsystemd-dev libpolkit-gobject-1-dev libqmi-glib-dev gettext xsltproc

Ubuntu 24.04.1 LTS Tested works well, but it was required shutdown laptop after disable service not sure why, without shutdown did not work, but after shutdown and run again it work well now.
