do you mean something like this:

-       bool (*eval)(const struct intel_gt *gt);
+       bool (*eval)(void *data);

?

I am missing the use case, though, what is it that cannot be
reached by the gt so that it needs to be more generic?

Do you want to use it at i915 level?

Thanks for the review,
Andi
