Bug Description

[Impact]

nvidia-dkms-390 fails to build with linux 6.2:

/var/lib/dkms/nvidia/390.157/build/nvidia-drm/nvidia-drm-drv.c:244:21: error: ‘struct drm_mode_config’ has no member named ‘fb_base’
  244 | dev->mode_config.fb_base = 0;
      | ^

[Fix]

Change the driver to support also the 6.2 kernel ABI.

[Test case]

With linux 6.2 installed, run:

$ sudo apt install nvidia-dkms-390

[Regression potential]

We may experience regressions in newer kernels (>= 6.2) that are using nvidia-dkms-390 (source code for previous kernels remain unchanged).

---------------
nvidia-graphics-drivers-390 (390.157-0ubuntu5) lunar; urgency=medium

  * debian/templates/control.in:
    - Drop i386 from the nvidia-libopencl1-384 and the
      nvidia-opencl-icd-384 transitional packages. This should allow
      correct migration.

Moving jammy to the same version of the driver used in lunar allows to use nvidia-dkms-390 both with the stock 5.15 kernel and the new hwe 6.2 (verified in a VM doing a simple test build).

Better debdiff to backport only the patch required to support linux 6.2 (that is much better from an SRU perspective). Tested with positive result in a VM both with 5.15 and the new hwe 6.2 kernels. So, please ignore my previous comment.
