Hi
I have the same issue building today’s v6.12-rc6 from kernel.org.
After a look in the code, the patch 446d0f48 had already been applied (code is the same as in v6.12-rc1)

After building debian kernel package of linux-6.12-rc6, while installing the debian created package, DKMS run to build NVIDIA module version 535.183.06.
It failed with error :

Configure linux-image-6.12.0-rc6-amd64 (6.12.0-rc6-1) ...
dkms: running auto installation service for kernel 6.12.0-rc6-amd64.

Refer to previous errors for more information.
dkms: autoinstall for kernel: 6.12.0-rc6-amd64 failed!

Having a look at the logfile, I found :

$ grep -i " error" /var/lib/dkms/nvidia-current/535.183.06/build/make.log
/var/lib/dkms/nvidia-current/535.183.06/build/nvidia-drm/nvidia-drm-drv.c:188:6: error: ‘const struct drm_mode_config_funcs’ has no member named ‘output_poll_changed’

cc1: some warnings being treated as errors

Google-ing the error message let me arrives here.

Any idea ?

Kind regards

Hi
I’m sorry for my last post, I was trying to use nvidia-driver packaged by Debian12 distribution.
Building linux-6.12-rc6 with NVIDIA DRIVER Linux-x86_64 version 535.216.01 was successfull with no issues !

So it seems that 535.183.06 version couldn’t be build with mainline kernel, user must use the last NVIDIA DRIVER version (here it works with 535.216.01) to build and use mainline kernel (ie 6.12-rc6 at the time I’m writing).

Kind regards
