The GPU doesn't have a closed driver that works either.
It's been a year for the JH7110 too, so I wouldn't hold my breath.
On Vision Five 2 everything is still softpipe in the official Debian from Star Five!
On the PineTab-V NOTHING involving the 3D part of the GPU works!
YouTube works for consumption, but that's not interesting for production.
To write/film a review of a SoC with GPU without running glgears is backwards.
I think the only hope now is for the upstream to gain a working driver in a year or two.
