Re: Re: Re: Severity: High / Debian 10 & 11 with Kernel 5.10.x-amd64 => Intel AX210 Wifi & Bluetooth not work
Salut Vincent,
I have found this way of doing things without having tested it yet, maybe it will allow Debian 11 to be compatible with my Wifi / Bluetooth card without having to install a future 5.11 kernel from backports ??
If you could get basic compatibility with the 5.10 kernel for bluetooth in addition to wifi, that would be really good.
Best regards.

I actually managed to make the AX210 run in Ubuntu 18.04 LTS with Linux Kernel 4.15! Here's what I did:
Install the "backport-iwlwifi-dkms" package (sudo apt install backport-iwlwifi-dkms)
Unfortunately, the iwlwifi sources in this package are too old and only support pre-production AX210, so:
Grab the up-to-date backport-iwlwifi sources from Intel's github repository: git clone https://github.com/intel/backport-iwlwifi.git
Now go to /usr/src, there's a subdirectory with the old sources from step 1 there (backport-iwlwifi-7906)
Copy the new sources to a new directory, e.g. sudo cp -a /whereever/you/cloned/to/backport-iwlwifi/iwlwifi-stack-dev backport-iwlwifi-8000
Copy the file "dkms.conf" from the old sources directory to the new sources directory and edit the second line to change the PACKAGE_VERSION from 7906 to 8000
Remove the bad dkms module that was installed with the package in step 1: sudo dkms remove backport-iwlwifi/7906 --all
Add the updated dkms module with the version just created: sudo dkms add backport-iwlwifi/8000
Build and install the updated dkms modules: sudo dkms install backport-iwlwifi/8000
Now the driver is ready, but you still need to get the firmware for the chip:
Clone the linux-firmware repository: git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
Pick out the firmware files you need and copy them to /lib/firmware. If you're not sure which firmware you need, just boot with the new driver and check dmesg for messages from iwl: dmesg | grep iwl - the firmware files it was looking for will be named there.
PITFALL: The AX210 also needs an additional "pnvm" file, which is also found in the repository, but not quite well mentioned by the driver. If it is missing, it'll spray a ton of error messages.
For my Intel AX210 module, I ended up adding these files to /lib/firmware:
-rw-r--r-- 1 root root 1413868 Jun 3 18:27 iwlwifi-ty-a0-gf-a0-59.ucode
-rw-r--r-- 1 root root 1455104 Jun 3 18:27 iwlwifi-ty-a0-gf-a0-62.ucode
-rw-r--r-- 1 root root 1460012 Jun 3 18:27 iwlwifi-ty-a0-gf-a0-63.ucode
-rw-r--r-- 1 root root 27456 Jun 3 18:46 iwlwifi-ty-a0-gf-a0.pnvm
And it is up and running!
