missing firmware in debian 9

missing firmware in debian 9

[Anil Duggirala]

hello,
I am getting this message at boot.

[   10.678576] ath10k_pci 0000:03:00.0: firmware: failed to load ath10k/pre-cal-pci-0000:03:00.0.bin (-2)

I have installed the firmware-atheros package from backports in Debian 9, I had installed the package from the main repository before but I was also getting this message. I have also installed the firmware-linux-free package.

Help please,
thanks,

Where should Debian take it when QCA is not providing a firmware-5.bin? Kalle 
Valo's repo [1] contains different firmware-6.bin (which your ath10k version 
doesn't seem to support yet) and firmware-4.bin. And Debian ships both - I 
think the ones which were in linux-firmware [2] at the time of the release.

I don't have a QCA6174 hw3.0 but I would guess that ath10k loaded the
firmware-4.bin after it failed to load the firmware-5.bin.

Kind regards,
	Sven

That's what I'm guessing as well. And these warnings should be visible
anymore with this commit:

c8e028026387 ath10k: use firmware_request_nowarn() to load firmware

https://git.kernel.org/linus/c8e028026387

It was introduced in v4.18 so once you upgrade the kernel to v4.18 or
later you should not see the warnings anymore.

I see that I am running kernel 4.9.0-8. It may be quite some time before I get to 4.18 right?
thanks,

How can I make sure this is the case? I have had a couple of issues with my bluetooth, how can I test it?
thanks very much,

ath10k prints lots of information to dmesg after it has initialised the
device, so check that. You should see the firmware version and what api
is used (the number N from firmware-N.bin).

> I have had a couple of issues with my bluetooth, how can I test it?

The warnings you posted are because ath10k is trying to find optional
calibration data and various firmware versions of firmware file from
user space. The warnings and commit c8e028026387 have nothing to do with
bluetooth, so that must be a separate issue.

Ok, I have checked and it is:
[    9.883661] ath10k_pci 0000:03:00.0: firmware: direct-loading firmware ath10k/QCA6174/hw3.0/firmware-4.bin

thank you Kalle and Sven,
