The GWG does have a LSK kernel branch with Mali support. (IE accelerated graphics)
We haven't targeted Android as of yet but in the grand scheme things should be reasonably close. Show can say for certain but we'd need a rebase on linux-linaro-lsk-v3.10-android at a minimum.
I'm a little unclear how interesting the LSK android kernel is for the Android team. One of my buffered questions for Khasim.

To be more clear. The board supports accelerated graphics but the LT kernel doesn't have the drivers to have accelerated graphics support.

Hi Botao,
There is no hw acceleration on arndale board.

Hi Vishal,
I'm now looking at the logcat output of Samsung Arndale Android image, and found:

As we know the Arndale board integrates dual-core A15 CPU and ARM Mali-T604 GPU. If as the log described, "No GPU support detected", then does it mean that all the graphic work now is done by the dual-core A15 CPU itself? Though the speed for navigation among screens is fast and 0xBenchmark test looks good as well.
I may be wrong but in this condition, the board seems can't be considered as "Hardware Accelerated", at least not "GPU Hardware Accelerated". Also, as I know, "Android PixelFlinger" is a software renderer.
Do you know more information about this?
Thank you.
