Use QCN9074 ath11k-card with OpenWRT v21.2.3

[balticfpga]

Hi,

I'd like to use a PCIe Wifi ax-card (QCN9074) on an x86-platform. The device shows up in "lspci".

root@openWRT:~# lspci
10:00.0 Network controller: Qualcomm QCN6024/9024/9074 Wireless Network Adapter (rev 01)

But, I can't use my wifi-card and there aren't any information or errors in the system log. I filtered the logfile with key words like "mac80211" and "ath11k" and looked for firmware-messages. But there weren't any information in the logfile.

This is my setup:

• I compiled openWRT v21.2.3 (kernel 5.4.188) for x86-64 platform.
• It seems that mac80211 uses ath11k from backports-5.10.110 (this information is derived from the build directory).
• After installing the openWRT binary on my target platform, I deployed the corresponding wifi-card firmware "ath11k" into "/lib/firmware".
• The wifi-card firmware is from https://github.com/kvalo/ath11k-firmware commit:b19cbdca78ab2adfd210c91be15a22568e8b8cae (May 9th 2022).

These are my questions:
Do you have any idea why I can't access my wifi card?
Is the ath11k-driver part of this version of mac80211?
Is there a list whether a firmware-version is compatible with a specific driver-version?

ath11k is not available in 21.02.x (and won't be), nor in the upcoming 22.03~rc (not likely to happen there either). Development for ath11k (albeit more with a focus on the ipq807x platform) is happening for kernel v5.15 and targeting the master branch (but not merged there either at this point.

This is not a bug report, but a feature request - which doesn't really need reporting, but providing the necessary patches.
