The question isn't absurd at all :)

There are hints in the driver code we use, that the driver should be able to support Cedarview GMA3600. Generally the kernel module is capable of being compiled for different SoC architectures and just needs some glue code for correct setup on a specific SoC. We have it running on several flavours of ARM and partially on one MIPS machine (JZ4780).

And Wikipedia says that Cedarview uses an SGX545 GPU which is in the focus of our project:


We have prepared the Makefile for Cedarview but not tested. Lack of hardware...

Another issue is user-space code. It seems as if Ubuntu 12 did support the GMA3600/SGX545, e.g.


but it may be difficult to make use of this in a different setup.

If you have such a device and want a challenging project with uncertain outcome, you are very welcome to join our project.

Best regards,
Nikolaus Schaller
