//! \brief      CmSurface2DUP Class to manage 2D surface created upon user
//!             provided system memory.
//! \details    Each CmSurface2DUP object is associated with a SurfaceIndex
//!             object containing a unique index value the surface is mapped to
//!             when created by the CmDevice. The CmDevice keeps the mapping b/w
//!             index and CmSurface2DUP. The SurfaceIndex is passed to CM kernel
//!             function (genx_main) as argument to indicate the surface. CPU can
//!             access the system memory through the memory point. GPU can access
//!             the 2D surface through SurfaceIndex in kernel. It is application's
//!             responsibility to make sure the accesses from both sides are not
//!             overlapped.
