Well, crap, 6.12 is here and I'm about to roll the dice. We will see if a patch is needed.
Uugh -- driver broke, it will need a patch. We will consult /var/lib/dkms/nvidia/390.157/build/make.log and go from there....
Success -- Patch 2 based on 470 driver
390xx driver patch needed a bit more than first attempt:

patch -Np1 -i ../kernel-6.12.patch
below the kernel-6.10.patch block.
This patch is a rewrite based on Joan Bruguera's 470 Driver patch Tested and working fine.
Good until 6.13 :)

Please don't flag this package out-of-date unless a new version has been released by NVIDIA.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-headersshould 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
linuxis not an installed kernel?jonathon commented on 2020-10-19 12:41 (UTC) (edited on 2021-05-11 14:18 (UTC) by jonathon)
PACKAGE NEEDS LONG TERM MAINTAINER
I have adopted the 390xx packages to keep them secure. I do not run any 390xx hardware so will not notice any breakages and cannot test any changes.
Until such time as someone else steps up to maintain these packages - ideally someone who actually has 390xx hardware - I have to rely on you to tell me what changes are needed.
Don't expect a response if you post only "this doesn't work", and do not email me to complain about the package not working!
Use this forum thread for discussion: https://bbs.archlinux.org/viewtopic.php?pid=1946926
A binary package is also available in my kernel-lts unofficial user repository.
