Ian, Matteo, thanks for your feedback.

Based on IRC discussion today, it looks like radeonsi is not
interested in gaining such a feature, and Ian's comments all point
away from exposing the actual hardware bits, which I think means this
ext is DOA. I don't think support in just nouveau + r600 justifies the
effort of getting this going -- too small of a user base between them,
and they can use nine if they really want better perf. I guess that's
why this ext died back in 2017 too, but at least now there will
hopefully be an easier-to-find record of it.

Cheers,
