Each GPU API provides a halide_device_interface_t struct pointing to the code that manages device allocations. You can access these functions directly from the struct member function pointers, or by calling the functions declared below. Note that the global functions are not available when using Halide as a JIT compiler. If you are using raw halide_buffer_t in that context you must use the function pointers in the device_interface struct.
The function pointers below are currently the same for every GPU API; only the impl field varies. These top-level functions do the bookkeeping that is common across all GPU APIs, and then dispatch to more API-specific functions via another set of function pointers hidden inside the impl field.
