Please only flag "out of date" the package when a new version of the driver is released. Tweaking the build process of the current version does not qualify as an "out of date".

@TechXero: have you tested the patch with various kernel / compiler configurations ? Does it work in all cases ?

Yep thanks for solution worked for me too.. I think an update is on the way.

For anyone having issues installing, downgrade GCC back to 13.2. GCC 14 breaks the dkms installation for this driver.

Downgrading gcc and gcc-libs to 13.2.1, then re-installing the current 6.8.9-arch1-2 of linux and linux-headers worked for me.

P.S. Thanks grzechoo and everyone for the solve. Not the way I wanted to spend my morning!

Downgrade gcc and gcc-libs to 13.2.1 and go back with your linux and linux-headers packages to 6.8.9-arch1-1. Latest gcc 14.1.1 causes NVIDIA dkms module installation to fail. Just figure that out after an hour of digging on internet and lately upgraded packages...

@pervokur may you provide more details on how to get that kernel version and how to set clang-17 with lto=none?

I'm guessing you installed that kernel manually ... so I supose if it works for 6.9.0 ... it should work for 6.8.x, should we flag this package as out of date?

Module works on 6.9.0-rc6 + clang-17 lto=none

I can't install the moduel for 6.8.9-arch1-2, like @erickwill

but the module either is installed for 6.6.30-2-lts !

Why is that? I've even tried to downgrade to 6.8.9-arch1-1 where I had the module working previously but still doesn't install!

Got an issue here while updating to the latest kernel linux-6.8.9.arch1-2 linux-headers-6.8.9.arch1-2.

==> dkms install --no-depmod nvidia/470.239.06 -k 6.8.9-arch1-2 Error! Bad return status for module build on kernel: 6.8.9-arch1-2 (x86_64) Consult /var/lib/dkms/nvidia/470.239.06/build/make.log for more information. =

here is the make.log:

Please, let me know if I can provide anything else. In this meantime, is there any workaround? Thanks!

I was able to compile kernel modules with clang-16 (my kernel is x86-64 6.7.8 clang-16 full lto)

1)edit conftest.sh change CC=$1 to CC=gcc, because this script isn't working correctly with clang-16

2) IGNORE_CC_MISMATCH=1 for me reported kernel compiler is something like "clang 16.0.6 ld.lld 16.0.6", so this environment variable helps me to pass compiler check

3) -MMD to -MD I wrapped clang-16, so -MMD option will be replaced with -MD. (maybe it's enough to remove '-MD' from Kbuild file, so there will no conflict between -MMD and -MD)
