cl_khr_3d_image_writes support GPUs

Hi,

I work 3D image using buffer object and it can be useful (meaning faster) to work 3d image object for read from(supported) and write to(not supported) . If I need list of GPU which support “cl_khr_3d_image_writes”.

So, where can I find a list of GPUs supporting “cl_khr_3d_image_writes” specifically, or list of extension supported by GPUs more generally.

I don’t find it, but if it doesn’t exists, it can be nice to do it for help people .

Thanks.
P.S. : I know that Nvdia GTX 285 and GTX 560 ti don’t support writing to 3D image buffer.
