During installation, "make" command not successful, prompts "Skipping BTF generation for /rtw89/rtw_8852be.ko due to unavailability of vmlinux"

[nikwou]

Currently running Debian 12 / bookworm / Linux 6.1.0-21-amd64 x86_64 . I believe starting with Linux 6.1.0-20 - several weeks ago -, the above notices appeared when trying to install the driver. The subsequent "sudo make install" command reports "success". However, the interface is down and not working. Previously, everything worked fine; I am not aware of any other changes I might have done. Any ideas what could be wrong are very welcome.

Does make report an error? If not, does the make operation produce *.ko files? If it does, the only problem is exactly what it says - vmlinux is not available. You need to look at the output of 'sudo dmesg | grep rtw' to see what it says. Otherwise, upgrade to sid with kernel 6.8.9 and use the in-kernel driver.

Thank you very much for the quick turnaround. I have posted the outputs of the respective steps (make, make install, dmesg). Looking at the directory after make and make install steps, I can see *.ko files, but only for the files not mentioned in make_output_1.log.txt ("Skipping BTF generation ...").

/usr/lib/firmware/rtw89 contains *.bin files, but they bear older date stamps (May 1st, 2023).

I have in deed tried to use higher kernel versions, but that brings other problems which I am unable to solve.

If the unavailability of vmlinux is the issue, would you be aware if a relevant storage location or something else could have been changed after kernel 6.1.0-15 or so?

Your firmware is old, but it should work.

make_output_2.log shows the .ko files being made.

I do not see anything wrong.

Is there any solution for systems with a core lower than 6.8.9? When making, Skipping BTF generation for is issued... for all files .ko and .oh, and the wi-fi module is not visible in the system, the bluetooth module is only running, I have no way to upgrade the kernel version. I try dkms version, but it doesn't work either. The system is proxmox 8.2.4 with 6.8.8-1 kernel
