OpenWRT integration
Opened this issue · 2 comments
Hi @lwfinger, thanks for your work.
I am trying to package this driver into OpenWRT in my repo.
To use it, one has to add this to feeds.conf.default: src-git rtl8852au_feed https://github.com/andrey-utkin/rtl8852au-feed
Here's the existing OpenWRT forum discussion, which for now doesn't have much info: https://forum.openwrt.org/t/add-rtl8852au-driver-to-kernel-module-but-ignored-when-building/156135/10
The driver builds and loads, but when it initializes the device, it causes a few warnings, apparently fails to register it, and a kernel oops happens.

I wonder if the problem is because of definitions not quite working due to build system being used differently.
On my laptop, I built it like make KSRC=/usr/src/kernel/version/ modules, while in OpenWRT it's more complicated so that I even ended up hardcoding -DCONFIG_LITTLE_ENDIAN for now, which let me to build it. Facing the current situation with the warnings and a crash, I tried adding hardcode of -DCONFIG_RADIO_WORK -DCONFIG_CONCURRENT_MODE to no effect.
I am writing here in hope that you may recognize the problem (and perhaps some other which will follow) and give advice.
Thanks in advance.
I did nto see any kernel oops, just warnings. Your first one is at
[ 209.504899] ------------[ cut here ]------------
[ 209.509563] WARNING: CPU: 1 PID: 3497 at ../backports-6.5/net/wireless/core.c:456 wiphy_new_nm+0x51c/0x570 [cfg80211]
I do not support backports, and I have no source to see what that warning is about. My guess would be that the call to wiphy_new_nm is not properly supported.
I have an 8842AU dongle, the Fenvi FU-AX1800P with USB ID 0bda:885c
Trying to get a driver that would work on a Raspberry Pi4 running OpenWrt 23.05.2 supporting this. Any hope?
