I might be pushing my luck here ... have you thought about basing
(forking) vc4-gpu-tools of intel-gpu-tools ? I'd imagine that the
macros and helpers will come in handy, despite that some are quite
intel specific.

On a related note - with the above project in place I'd imagine you
have (re)considered about having libdrm-vc4 ? Copying hunks around
might lead to interesting moments (as you have already noticed :-P)

On that note I'll stop now with beating the libdrm drum :-)

Thanks
Emil
