#75974 — Bug#919652: ath10k - QCA6174 - Surface Go - missing board data - fix .bin included extracted form official .msi

Package: firmware-atheros
Version: 20210818-1
Followup-For: Bug #919652

Hi,

I'd suggest submitting the board files to the ath10k-firmware repo,
which will then find it's way into linux-firmware. See [1] for the
proper process description. However checking the license text would also
be required beforehand.

fwiw this (or, well an update of the existing one) actually happened
already at the end of 2021 [0], but Debian hasn't seen an update so far.

[0] https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=4d74f4dec175363fa24c95702dd86f477cef232c


With that board file wlan works even through the kernel (at least on
bullseye, not tested others) still complains about missing firmware:

ath10k_pci 0000:01:00.0: firmware: failed to load ath10k/pre-cal-pci-0000:01:00.0.bin (-2)
fimeware_class: See https://wiki.debian.org/Firmware for information about missing firmware
ath10k_pci 0000:01:00.0: firmware: failed to load ath10k/cal-pci-0000:01:00.0.bin (-2)
(followed by messages about successfully loading firmware-6.bin and board-2.bin)

The internet says these files are optional, which is somewhat confirmed
by having working wlan even without them, and I fail to find them – but
find some references to them in Debian forums as e.g. also d-i shows its
missing firmware message for those files (even if you have the firmware
cd variant, which is both annoying and confusing).

Not well versed in kernel code, but while [1] claims (at least for the
cal file) that it is optional and should print no warning it happily
still does anyhow? Or perhaps its ath10k_fetch_fw_file() doing a
firmware_request_nowarn() to then go on and ERR_PTR() on its own… [2]
Anyway, not really the point of this bugreport, just at the off chance
someone has an idea how to proceed on this somewhat related front.
