So, just to toss out a completely different idea..
What if instead of a new ioctl, we had a read-only blob property
(which encoded the info basically the same way, plus the fourcc's)?
If we do writeback via some sort of OUT_FB_ID property on plane/crtc,
we will need the same sort of format information so userspace knows
what output formats (and modifiers) are supported. So re-using the
same blob property layout (and userspace parsing) seems useful.
