I've made a test kernel build with drm_panic enabled (and VT_CONSOLE
disabled):

I've backported a few patches, that are not in v6.10, like:
short panic description:
https://patchwork.freedesktop.org/series/135356/
kmsg panic_screen:
https://patchwork.freedesktop.org/series/134286/
draft nouveau support (tested on 1650X, might be garbage on other GPU):
https://patchwork.freedesktop.org/series/133963/
And also virtio-gpu support, so you can test it easily on a VM.

To install the test kernel, download the rpms kernel, kernel-core,
kernel-modules, kernel-modules-core, kernel-modules-extra, and install
them with dnf.
It's a Fedora rawhide kernel, but can be installed on F40.

i915, amdgpu, and nvidia are not yet supported, so you need to blacklist
them, in order to use simpledrm, if you want to see the panic screen.


Do you expect to see the rest of the drivers supported by the time
Fedora 42 rolls around? Because if it only works with nouveau, it's
probably not worth enabling.


I think it's a bit of a chicken and egg problem. If no distro enables it, there will be little incentive for the drivers to add support.

Also, on all hardware, simpledrm is used at boot, so common kernel panic like "unable to mount /", or "failed to execute /init", will use drm_panic.

FYI, I opened an issue for amdgpu here:
https://gitlab.freedesktop.org/drm/amd/-/issues/3340

And for i915 here:
https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/10954
