WebNote that OpenCL 2.0 introduces SVM buffer. SVM is generally not supported for image object s. To create an image object from an SVM buffer, pass the SVM buffer as a pointer to the clCreateBuffer function as its host_ptr argument with the CL_MEM_USE_HOST_PTR flag. In this case clCreateBuffer succeeds and returns a valid non-zero buffer object.
