unable to load firmware for wlan adapter

[antst]

Describe the issue you are experiencing

I am trying to get Intel BE200 working. Out of the box it does not work, as HAOS packs outdated firmware. Trying to update firmware using workaround #2225 does not work either, as it seems that /mnt/data/supervisor/firmware is mounted way too late, after iwlwifi is already loaded with an error.

# dmesg | grep iwl
[    1.842538] iwlwifi 0000:01:00.0: Detected crf-id 0x2001910, cnv-id 0x2001910 wfpm id 0x80000000

if after boot finished, in console I do

#rmmod iwlwifi
#modprobe iwlwifi

then module will load firmware and I get working interface. And then dmesg will show proper load.

# 

so, workaround #2225 is only half-working. Suitable only for firmware loading at later stages.

so, we need either to mount /mnt/data very early in boot (but still unlikely to be good enough) or find a way to inject firmware to initrd or, ideally, have consistency between kernel modules and firmware versions :)

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

13.2

Did the problem occur after upgrading the Operating System?

No

Hardware details

QEMU/KVM 9.0.2
PCI (WLAN) and USB(BT) passthrough for BE200

Steps to reproduce the issue

1. Install Intel BE200 adapter
2. Create (if missing) /mnt/data/supervisor/firmware
3. Put iwlwifi-gl-c0-fm-c0* files from fresh linux-firmware git
4. Boot
   ...

Anything in the Supervisor logs that might be useful for us?

so, workaround #2225 is only half-working. Suitable only for firmware loading at later stages.

Your conclusion is (almost) correct, WiFi is indeed initialized too early and adding the firmware to the symlinked directory doesn't work. However, the problem isn't the inconsistency between firmware versions and kernel - the firmware for BE200 is simply not installed by the linux-firmware package. Also note that HAOS doesn't use initrd.

As a remedy for your problem, the solution would be to add the firmware to the list of installed firmwares for Intel WiFi cards. Unlike other distributions we don't to that pre-emptively, as we need to cope with rootfs space constraints, but given that this WiFi cards doesn't seem to be an obscure one, adding support for it makes sense to me.

Hm...strange, my memory tells me that I spotted somewhere firmware, but wrong versions, bellow iwlwifi-gl-c0-fm-c0-80 or above iwlwifi-gl-c0-fm-c0-83. But maybe my memory didn't serve well :)
Because right now I am checking and don't se any IWL firmware which would match iwlwifi-gl-c0*.

[antst]

so, question is...any workaround? before firmware find its way into hassos?
And how I can speedup inclusion of firmware?

[antst]

OK, to simplify life for everyone, I added PRs to two repos
#3668
and
home-assistant/buildroot#59

merge of those should add driver for iwlwifi-gl devices

[antst]

and, as temporary workaround, I built my pwn image with provided patches, and updated with rauc. So, patches are also checked to work.
