Hi Daniel,

I think for a substantial improvement here in robustness what you
really
quoted
quoted
want is
- kmscon in userspace
- disable FB layer
- ideally also disable console/vt layer in the kernel
- have a minimal emergency/boot-up log thing in drm, patches for that
  floated around a few times
I assume you refer to this work by David Herrmann:
"[RFC] drm: add kernel-log renderer"
https://lists.freedesktop.org/archives/dri-devel/2014-March/055136.html
There's also this:

[PATCH v2 0/3] drm: Add panic handling
https://lore.kernel.org/dri-devel/20190311174218.51899-1-noralf@tronnes.org/ (local)

And here's a DRM console example that was part of the early drm_client work:

[RFC v4 25/25] drm/client: Hack: Add DRM VT console client
https://lore.kernel.org/dri-devel/20180414115318.14500-26-noralf@tronnes.org/ (local)
