Fusion and OpenCL

Hi!

 

Maybe I didn't search hard enough, but I haven't really found any developer documentation or guide on programming specifically AMD Fusion processors, so I would like to have some more info on that (I did find OpenCL guides, but not specific guides on optimizing for Fusion).

 

To be exact, one of my questions:

* How is the memory between CPU and GPU in Fusion handled in OpenCL? Is a copy/"upload" still done from CPU memory to "GPU memory" (when mapping/unmapping buffers for ex.), or is it possible to just pass a pointer somehow to host-allocated memory to OpenCL calls?

 

Thank you very much in advance!
