[SOLVED] new kernel 6.9.0 and nvidia drivers

Toutatis · 05-16-2024, 01:38 AM

On slackware64-current, kernel 6.9.90 boots correctly, but Nvidia driver 470.239.06 cannot be built

Thanks for the heads up. I was afraid there would be problems.

According to the nvidia forum, this is related to gcc-14 and should be fixed with three patches:

Do you know how to rebuild a Nvidia run file, after it has been extracted and the patches are applied ?

run ./nvidia-installer

Thank you very much marrowsuck and willysr. Everything works !

Could someone post an over view of how to apply the patches to Nvidia driver 470.239.06 ?

I have had little experience patching.

Thanks in advance.

I usually patch the installer

Code:

sh NVIDIA-Linux-x86_64-470.239.06.run --apply-patch PATCH-FILE

And here is the patch

Nvidia 550.76 works for me with kernel 6.9.0. (The latest, 550.78, probably works, too.)

But I need help patching Nvidia 550.54.14 (the latest that's compatible with cudatoolkit 12.4.1) to work with kernel 6.9.0.

Is there a patch for this?

Update: It's solely an nvidia-drm issue. I prepended NV_EXCLUDE_KERNEL_MODULES=nvidia-drm to make and deleted the install nvidia-drm line, and everything else built successfully!

Tested here with 470.239.06 built kernels 6.6.30 and 6.9.2 with no issues. Currently using 6.9.2, 6.6.30 is a back up.
