yes, that should also run on a GTA04 with Darwin kernel.

What IMHO is also worth discussing is the upsides and downsides of the idea to run a non-Linux kernel to the GTA04.

Some of my thoughts:
* AFAIK Darwin has a more fine grained power management scheme (I don't know if it is implemented for our SoC or if it is a ToDo)
* the IOKit driver model uses C++ for writing drivers (which should be more powerful)
* Darwin is optimized for audio and video
* Darwin has very stable APIs (external and internal)
* but it lacks a lot of drivers that are available in Linux
* it also lacks a big and vital developer community

me too :)

I still expect some challenge...
