in AMD Accelerated Parallel Processing Document (rev2.1b), it says that the "zero copy buffers" is a new feature of AMD APP SDK 2.4 on windows, my questions is that is zero copy supported by Linux?
This is a useful link.
Actually, I believe zero-copy is currently supported on Linux with sdk 2.7. But there are strange limitations, like being limited to allocations in size of 1/8 of physical memory of the host etc. You could perhaps test it out anyway? It works much better on Windows for sure.
