About OGL Cayman  support for DUAL DMA and dual setup/geometry engines!

Hi,

I want to ask about OpenGL exposure of 6900 (cayman) features..

first it seems tessmark shows dual geometry/setup/tetesselator engine in cayman not working inogl.. how it will take to have an opengl supporting driver?

Also cayman has dual dma engine similar to nvidia fermi..

well nvidia has created a whitepaper showing how to exploit in opengl applications (named NVIDIA Quadro Dual Copy Engines) here:

http://www.nvidia.com/docs/IO/40049/Dual_copy_engines.pdf

seems you need two ogl contexts to exploit advantage of it via async buffer objects copies..

I question if right now using similar code will exploit cayman dual dma engines?

if not, will opengl driver take in near future? i.e. there are plans to expose it?

also a code sample showing how to exploit optimally once implemented would be good.. 

 

thanks.
