I have a problem. I want to implement transfer using pinned host memory (NOT zero copy buffer).

According to table memory object in AMD APP SDK, it can be achieve by using CL_MEM_ALLOC_HOST_PTR +  using CL_Enqueue_Map_Buffer.

If I use it,the result is zero copy buffer since VM is enabled by default.

According to table, to achieve transfer data using pinned host memory, we can use   CL_MEM_ALLOC_HOST_PTR +  using CL_Enqueue_Map_Buffer without VM.


So, How to disable virtual memory (VM) ??
