I'll try to extract the "executive summary" from this, you tell me if I got it right.
So using or not using dynamic debug for DRM debug ends up being about shifting the cost between kernel binary size (data section grows by each pr_debug call site) and runtime conditionals?
Yes.
Since the table sizes you mention seem significant enough, I think that justifies existence of DRM_USE_DYNAMIC_DEBUG. It would probably be a good idea to put some commentary on that there. Ideally including some rough estimates both including space cost per call site and space cost for a typical distro kernel build?
yeah, agreed. I presume you mean in Kconfig entry, since commits have some size info now - I have i915, amdgpu, nouveau; I can see some prose improvements for 5/8
