A couple weeks ago, qualcomm (quic) surprised some by sending kernel patches to enable the new adreno 4xx family of GPUs found in their latest SoCs. Such as the apq8084 powering my ifc6540 board with the a420 GPU. Note that qualcomm had already sent patches to enable display support for apq8084, merged in 3.17. And I'm looking forward to more good things from their upstream efforts in the future.
So in the last weeks, in between various other kernel work (atomic-helper conversion and few other misc things for 3.19) and RHEL stuff, I've managed to bang out initial gallium support for a4xx. There are still plenty of missing things, or stuff hard-coded, etc. But yesterday I managed to get textures working, and fix RGBA/BGRA confusion, so now enough works for 'gears and maybe about half of glmark2:
I've intentionally pushed it (just now) after the mesa 10.4 branch point, since it isn't quite ready to be enabled by default in distro mesa builds. When it gets to the point of at least being able to run a desktop environment (gnome-shell / compiz / etc), I may backport to 10.4. But there is still a lot of work to do. The good news is that so far it seems quite fast (and that is without hw binning or XA yet even!)
