How to add ath11k in package mac80211(AX3600)?

[gmzhuo]

Hi All,

We have ethernet on AX3600 now, I want to try ath11k on it.
How can I add ath11k kernel module in mac80211?

Thanks!

You'll need the top three patches (that doesn't mean that will be sufficient).

I don't like ath11k
This is qca-wifi

AmadeusGhost/ipq8074

I applied this patch, but I still can't select and enable ath11k module.
Don't know why.

I need to remove the directory tmp to recollection the package info then I can find and select ath11k.

Thanks!

Btw., I think (based on your diff above) you might be missing the changes to target/linux/ipq807x/config-default.

$ git diff remotes/origin/master..HEAD | diffstat -p1

Failed to build package mac80211.
Why I need to change the kernel config?

ERROR: module '/data/work/buildopenwrt/master/openwrt/build_dir/target-aarch64_cortex-a53_musl/linux-ipq807x/backports-5.8-rc2-1/drivers/net/wireless/ath/ath11k/ath11k.ko' is missing.

You question is answered in the commit description of:
https://git.openwrt.org/?p=openwrt/staging/hauke.git;a=commit;h=63a02112ef1ca906eff3868f0c163887a91a3311

You will also need the DTS entries for wcss pil, see example documentation :

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux.git/tree/Documentation/devicetree/bindings/net/wireless/qcom,ath11k.yaml?h=for-next

[gmzhuo]

Thanks all of you, I'll try it later.

[Apache14]

Fantastic work on the eth driver by the way, ill build with your changes later today.

Its also worth looking at how stock FW extracts calibration data, I have extracted the following from the stock rom

            ap-hk* | ap-ac* | ap-oa*)
                    mkdir -p ${apdk}/IPQ8074
                    dd if=${mtdblock} of=${apdk}/wifi1.caldata bs=1 count=2116 skip=208896
                    if [ -f "$HK_BD_FILENAME" ]; then
                        FILESIZE=$(stat -Lc%s "$HK_BD_FILENAME")
                    else
                        FILESIZE=131072
                    fi
                    dd if=${mtdblock} of=${apdk}/IPQ8074/caldata.bin bs=1 count=$FILESIZE skip=4096
