ath11k/ath12k firmware missing, CONFIG_IRQ_REMAP not defined either

[OdinVex]

Describe the issue you are experiencing

I've attempted to add the firmware for ath11k and ath12k (to support my 17cb:1107 WiFi 7 card) to /mnt/data/supervisor/firmware and reboot but I'm not sure it's loading, dmesg's only output is:

[    5.322474] ath12k_pci 0000:06:00.0: BAR 0: assigned [mem 0xf0200000-0xf03fffff 64bit]
[    5.322512] ath12k_pci 0000:06:00.0: enabling device (0100 -> 0102)
[    5.323444] ath12k_pci 0000:06:00.0: failed to get 16 MSI vectors, only -28 available
[    5.323473] ath12k_pci 0000:06:00.0: failed to alloc msi: -28
[    5.325225] ath12k_pci: probe of 0000:06:00.0 failed with error -28

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?

6.6.46-haos

Did the problem occur after upgrading the Operating System?

Ongoing

Hardware details

17cb:1107, WiFi 7 Card, a Qualcomm "FastConnect" WCN7850 (WCN7851) M.2 M-Key.

Steps to reproduce the issue

1. Install an ath11k/ath12k wireless card.
2. Boot the system
3. Copy firmware files.
4. Reboot.

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

N/A, None

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

System information

No response

Additional information

Permissions on the files are correct, I even tried just copying ath11k and ath12k folders alone since they don't exist in HAOS, no effect. Rebooting server doesn't change anything.

linux-firmware has it and supposedly it's been supported since kernel 6.3. I'm thinking the driver isn't detecting the firmware files because of the whole symlinking deal.

[OdinVex]

Some digging around, this might be a two-part issue? One is the missing firmware but the other is the driver not being able to allocate MSI vectors. Some google-foo shows people getting it to work on systems by compiling the kernel with "CONFIG_IRQ_REMAP" enabled.

It's not showing any firmware files, so that's of concern but maybe that gets loaded/used after the MSI bits?

Edit: Attempts to rmmod and insmod don't change whether it shows firmware files loaded by the module or not.
Edit: A grep of kernel compile flags shows CONFIG_IRQ_REMAP is not set, that may be required for cards such as these?

-28 is ENOSPC, and it seems that CONFIG_IRQ_REMAP is about IRQ remapping. On my Arch Linux distribution that config is enabled, I think we can safely enable it for HAOS as well.

Same for my Manjaro installation and an Ubuntu Server I manage. Edit: It'd also be nice to include the ath*k firmwares out-of-box considering they're required for many net-related devices.

Hm, we don't ship any ath11k today, I guess shipping firmwares for the chips which are available as a general purpose PCIe device makes sense. The problem is, things are a bit tight on the root file system partition, so depending on size, it might not be possible to add the firmwares right now. I'll leave this up to @sairon to decide.

ath11k or ath12k. The firmwares I'm more focused on are for wireless cards. I don't know enough about HAOS to know why the root filesystem would (edit )have constraints but those firmwares are important to get networking going. I'm guessing it has to do with HAOS devices (Green/Yellow/Blue)?
