ath10k_pci firmware issue

Hello. My wireless card can't start with latest linux-firmware (20210208.b79d239-1).

$ sudo dmesg | grep -i ath10

$ lspci -k | egrep -Ei "ath10|qca6174"

kernel parameters:

I have already tried to use firmware from https://github.com/kvalo/ath10k-firmware, but got exactly same error. Thanks.

Re: ath10k_pci firmware issue

For what it's worth, this might be a bit off topic, but it will point you to the right direction. https://wiki.archlinux.org/index.php/Bl … ernel_5.10

Basically, with kernels >5.10 there is problem with bluetooth on wifi card. I experienced this and can confirm, your computer does not see bluetooth adapter located on your wifi card. Dropping to 5.54 LTS kernel fixed the issue for me.

Reason this could be solution to your problem is because your wifi card has a single chip that controls both wifi and bluetooth.

Designed to deliver a cost-effective Wi-Fi/Bluetooth combo solution, the Qualcomm® QCA6174A SoC (System-on-Chip) is an integrated, single-chip solution in a small form factor for mobile and consumer electronics applications.

So, this too can be your solution, dropping to 5.54 kernel. (but not forgetting to file a bug report so it gets fixed in the future) But don't give up this easily, maybe there is a fix for you, keep looking.

P.S. Go ahead and do that btusb-210681-fix described in wiki.

Re: ath10k_pci firmware issue

u666sa, thanks for your reply, but I don't need Bluetooth functionality, all I want from my QCA6174 is WiFi
But I don't sure if kernel downgrade would help in my case, because problem is at firmware part, which is moved to linux-firmware package.

BTW my kernel is 5.10.18-hardened1-1-hardened
