zero copy and OpenCL 2.0 coarse-grain share virtual memory

Hi all,

 

I used to implement zero copy in AMD APUs using OpenCL 1.2, now since the OpenCL 2.0 is ready, what is the difference between zero copy and OpenCL 2.0's coarse grain shared virtual memory.

Is OpenCL 2.0's coarse grain shared virtual memory another form of zero copy?
