Please don't flag this package out-of-date unless a new version has been released by NVIDIA.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

I've made a patch for 6.15 kernel support, it would be nice if some will test it on real hardware.

I've just added gcc-15.patch from bufferunderrun.

Thanks to all of you who took part in patch research and testing!

just to add one more confirmation: after adding gcc-15.patch the build works perfectly here, many thanks for your work! -s

gcc-15.patch worked fine here as well. So, it seems we can add that patch to the package right ?

Considering:

* package is broken in its current state

* the patch is required for this package to be compatible with archlinux's current version of gcc

I just used the patch gcc-15.patch of bufferunderrun here and upgrading to kernel 6.14.5-arch1-1 and gcc-15 was successful.

I could be missing something obvious,

Of course I'd forgotten to the patch entry to prepare(). Thanks @bufferunderrun.

And sorry to everyone else for the spam. Incredible work with the patches, investigations and brainstorming.

I assume you added it with a relative path and it's not adding the patch. This should work:

patch -Np1 -i "${srcdir}/gcc-15.patch" -d "${srcdir}/${_pkg}"

No issues with linux 6.14.5

EDIT: I used makepkg -sifc

I could be missing something obvious, since I normally use paru and haven't done this manually recently.

1. Downloaded the content of gcc-15.patch from @bufferunderrun, with and without the addition from @drankinatty.

2. Modified PKGBUILD

3. updpkgsums

4. makepkg -sic

pacman "succeeded", but dkms install --no-depmod nvidia/390.157 -k 6.14.4-arch1-2 exited 10. In the make.log, there were a lot of issues with conftest.sh. A snippet from ~600 lines is given below:

Does anyone know what could be wrong?

I have put a write-up on The bbs.archlinux.org discussion page outlining where I think the 6.15 kernel problem will be. If you can take a look and add any thoughts you have on the differences with the 390 driver common/inc/nv-mm.h and how to backport the patch from the 470 driver to that file -- that is where I'm stuck.
