Arch Linux User Repository

Zenm Chen has provided a fix which allows the driver to build on Arch Linux kernels again. You should be able to clone my repo directly and build it.

I also request the maintainers to update the diff or just track my repo.

I am trying to build your repo for kernel 6.15.3, specifically 6.15.3-1-MANJARO.

Process: While being in Manjaro on kernel 6.14, because under kernel 6.14 the driver actually works and I can go online for help and debugging:

• git clone https://github.com/natimerry/rtl8852au
• cd rtl8852au
• sudo dkms remove rtl8852au/1.15.0.1 --all
• sudo rm -rf /usr/src/rtl8852au-1.15.0.1
• sudo dkms add .
• sudo dkms build rtl8852au/1.15.0.1 -k 6.15.3-1-MANJARO

Cut here because comment is too long

Hey,

So I have updated the patch once more to not use EXTRA_CFLAGS in the kernel (not that it matters too much for reasons I will mention later) and use a more modern approach that builds for kernels that disable the EXTRA_CFLAGS option. My only testing was on Arch kernel. However it seems like arch has stopped shipping kernels with CONFIG_WIRELESS_EXT enabled, and this is a hybrid driver (which means it registers with the newer cfg80211_ops format but also registers wireless handlers which are no longer supported by the latest arch kernel. Now I am not familiar with Larry's massive codebase but I am going to be see what I can do and going to push my updates if I can remove all wireless handler code or make it conditional. I will email the maintainer if I am successful.

Till then your only real option appears to be to use a distro that enables that option OR use a kernel (custom kernel or something like linux-tkg / cachyos whatever) which still ships with CONFIG_WIRELESS_EXT.

Thats a bit weird, im out right now so I cant test this just yet. But you can dm me on discord if you are on it (same username as here) as that's more convenient imo.

Edit: Just tried this on my laptop running cachyos 6.15.2-2-cachyos and it builds fine on my end. @Stonemincan dm me on discord and maybe i can send you the .ko file or the build directory for you to run make install on. `

@natimerry sorry I forgot to return and include that:

os_dep/osdep_service.c:17:10: fatal error: drv_types.h: No such file or directory

this is if I use make in the rtl8852au folder. I see that file in the include folder though. If i try to use makepkg after patching this package, it will build the package after patching the correct files ostensibly, but then when using the package to update with pacman I get the same error as with the unpatched package:

Error! Bad return status for module build on kernel: 6.15.2-arch1-1 (x86_64)

Also, I noticed the maintainer has updated this pacakge, but it still fails to build against 6.15.

@Stonemincan can you specify in more details where the build fails? Would be great if you could upload the output of the make

@natimerry thanks for your help. I applied the patch but building on 6.15 was still unsuccessful. I also couldn't get your github fork to work. Could you please advise?

https://patch-diff.githubusercontent.com/raw/lwfinger/rtl8852au/pull/115.patch

Patch fixing breakage on kernel 6.15, sorry it took me a while. You could also just use my tree to build the driver manually https://github.com/natimerry/rtl8852au as the maintainer seems to have abandoned this driver.

Edit: The maintainer Larry Fingers has unfortunately passed away last year. I will continue to try maintain the driver to build with newer kernel versions.

Is there a patch for 6.15?
