Yeah, please do test this to make sure we are not missing anything :)
I used buildroot ( https://buildroot.org ) to generate a kernel + rootfs
for my board (a variation of qcom/msm8998-mtp.dts)
Not sure if I must use the vendor FW blobs? Or if I can use the blobs
from linux-firmware-20240115.tar.xz (as supported by BR2).
All I see from the ath10k driver (with debugging cranked to the max) is:
[ 0.539801] ath10k_snoc 18800000.wifi: Adding to iommu group 0

I got shell-shock from reading these setup steps:

Jeffrey, Bjorn, Konrad,
Has someone written idiot-proof (such as myself) steps to enable
the ath10k core on a msm8998 board?
$ cat /tmp/x.json
[
{"names": ["bus=snoc,qmi-board-id=stinkyboard"], "data": "board_stink.bin"}
]
$ ls -lh board_stink.bin
-rw-rw-r-- 1 konrad konrad 19K Mar 13 16:42 board_stink.bin
$ python3 ~/qca-swiss-army-knife/tools/scripts/ath10k/ath10k-bdencoder -c /tmp/x.json -o board-2.bin
board binary file 'board-2.bin' is created
I believe Kalle aggregates these boardfiles and then uploads a big
combined board-2.bin to linux-firmware nowadays?
