AI-generatedOpenCL 3.0 optional SVM support limits portable zero-copy sharing
A design goal is to define portable limits for zero-copy host-device buffer sharing across OpenCL 3.0 implementations without assuming optional features. Device limits for allocation size and base address alignment are device-specific and must be queried at runtime. CL_MEM_USE_HOST_PTR and CL_MEM_ALLOC_HOST_PTR have implementation-defined requirements for po
