Cannot build on Linux Kernel 6.11.3-3-cachyos

[mxaban]

When trying to build the module it gives me the following error:

Install DKMS modules
==> dkms install --no-depmod rtw89/r1090.d1fced1 -k 6.11.3-3-cachyos

A similar error appears with rtw89-BT

Any help is appreciated, thanks

I think you can just use built-in driver of kernel 6.11.
Did you encounter problems? Which WiFi chip you are using?

[kihiukiragu]

Also have the same issue:
Kernel: 6.11.5-amd64
WiFi Chip: Realtek RTL8852BE PCIe 802.11ax Wireless

Built in driver doesn't appear to work.

[pkshih]

We found interoperability problem if platforms are not Intel, and the patch is draining to stable 6.11.
Please try kernel 6.10 with built-in driver to see if it works to you.

By the way, attaching log will be helpful to understand the case you met.

This is the error I get when I run make:

However, I tried the code from the pending pull request #366 and it builds ok, but the WiFi is still not recognized :(

I will try kernel 6.10 as suggested and see if that works for me.

I can easily build module on latest 6.12 cachyos kernel.

Also there could be some regression/bug:
On 6.6 kernel when downloading large files via wifi (5GHZ) my BT audio and mouse ok, on 6.12 OR your dkms = its choppy and unresponsive.

@ppogorze

Do you wanna try my rtw89 driver? kernel 6.6 ~ 6.13 are supported.
this driver comes from linux-mainline (the upcoming kernel 6.13) and it works with my 8852BE but BT is not tested.
You can simply install rtw89-dkms-git if you are using a Arch-based Linux distro.

[ppogorze]

Thanks, great.
Weird thing is when I connect AirPods (even for a few seconds) my all issues is gone until reboot.

I will test your driver and come back with more info.

btw nothing weird in btmon, journal and dmesg

edit; same issue with dkms from arch. maybe its related to usb power management in newer kernels, because bluetooth is using btusb?

I'm not a pro driver programer, so the only thing I can do is backporting the latest stable rtw89 driver to older kernels.
if you found the latest stable driver still has some issues, it is recommended to email [email protected] as mentioned in README.md
sorry that there is nothing I can do. :)
