I tried something like that:

There were many suggestions, a completely refactor of the idea (panic
lists are not really seen as reliable things).

Given that, I'm not really sure splitting in lists gonna fly; maybe
restricting the test infrastructure to drm_panic plus some paths of
panic would be enough for this debugfs interface, in principle? I mean,
to unblock your work on the drm panic stuff.

Cheers,
