Thanks very much for the pointer. I managed to find the exynos Xorg
driver in use, but unfortunately the only tbm backend I could find is
labelled for exynos4412. Is this backend also usable on 5xxx/XU3, or
is that backend really only for Trats2, and the 5xxx backend is
private?

Anyway, regardless of that, as far as I can tell, the Xorg driver uses
TBM to do buffer mapping, and the TBM backend uses DUMB_MAP rather
than the new call here. Is there something I'm missing?

(In any case, having separate-from-Tizen userspace graphics stack
repositories would be very welcome, I think: there are a huge number
of repositories for Tizen - something like six copies of libtbm alone
- and it is unclear how to build them on a generic userspace / if they
will actually build at all / if they will run on mainline kernels.
Having a separate tree will make it very clear to people how to get
things working on top of a mainline/staged-for-next kernel.)

Thanks very much for your help finding this!

Cheers,
Daniel
