For radeonsi, I think the question is more "when", not "if". At least 
PRT/sparse textures are necessarily immutable, so the associated Mesa 
headache should be bounded, but still...

As you know, I think the ioctl interface is good.

One thing to keep in mind is that I don't know how well PRT layout is 
supported by the open addrlib. There have been a bunch of PRT-related 
fixes in the internal copy of addrlib, but opening them has been stuck 
in review limbo for a while now...

Cheers,
Nicolai
