Please don't flag this package out-of-date unless a new version has been released by NVIDIA.

The DKMS package guidelines are explicit that linux-headers should not be a dependency of any DKMS package.

As a concrete example of why including that as a hard dependency is a bad idea, what happens when linux is not an installed kernel?

It is official, the linux-6.9.1 package hit the core-testing repo at noon today. The only patches I have found are initial support patches for 6.9 for Cachyos that are a couple of months old at that point, e.g. https://github.com/CachyOS/kernel-patches/blob/master/6.9/misc/nvidia/ I doubt those will be complete and will need to be cherry picked for 470 and 390 if applicable.

Good news is it looks like it is just the GCC-14 patch that is needed, so there may be no other breakage by the kernel update from 6.8 - 6.9. Here is the nvidia forum link: https://forums.developer.nvidia.com/t/nvidia-modules-470-239-06-build-failure-with-gcc-14-due-to-conftest-sh/292645

This was referenced from a Slackware thread about failure to build with the 6.9 kernel. https://www.linuxquestions.org/questions/slackware-14/new-kernel-6-9-0-and-nvidia-drivers-4175737070/

@Minty95 I use the linux-zen kernel, so I added the following line to pacman.conf

IgnorePkg = linux-zen linux-zen-headers

Remove the "-zen" part of the names if you use the standard kernel

sfranchi : Kernel and headers packages added to my pacman ignore list what exactly did you add ? so that I can do this as well,Thank :)

Many thanks did that, works perfectly. I'll now will wait until the maintainer has time to update the kernel

Thanks for the heads-up @drankinatty. Kernel and headers packages added to my pacman ignore list until the patch is out.

Oh Joy, the Linux 6.9 kernel was just released by Linus and crew, so we should probably start looking for patches. Arch is probably a week or two away from getting the package out. I'll start looking at the current driver changes. If anybody comes up with a 6.9 kernel patch -- post a link.

@rodrigorc thank's to share.

Work's fine on my system.

I got an error dkms error WARNING:dkms install --no-depmod nvidia/390.157 -k 6.8.8-arch1-1' exited 10`.

I don't understand why dkms still building with kernel 6.8.8 when I'm using kernel 6.8.9 but with kernel 6.8.9-arch-1-2 building successfully but OpenGL not working at all. :/

Back to nouveau for now.

EDIT: removed old modules from /usr/lib/modules and compiled this package again with @aruncveli linked patch, now work. :)

I hadn't read this thread, so I fixed it myself, with this patch:

I think this is more proper, GCC itself recommends using -fpermissive if there is need for the legacy behavior: https://gcc.gnu.org/gcc-14/porting_to.html

The change about NV_CONFTEST_CFLAGS I copied from the nvidia-470xx-utils file. They are mostly identical, but this one were missing that extra bit that forwards the extra flags to the conftest script.

Thank you @aruncveli - that patch does work. I thought it would take much more than that? But I just built the package with the patch (applied - patch -Np2 -i ../../gcc-14.patch) and both LTS and the normal kernel modules built fine. This patch works.
