…work Rename cuda/core/_graph.py to cuda/core/_graph/__init__.py to create a package that will house the explicit graph construction module alongside the existing stream-capture-based implementation. Ref: NVIDIA#1317 Made-with: Cursor
Phase 1 groundwork for explicit CUDA graph construction (issue NVIDIA#1317): - Add HandleRegistry template for reverse-lookup of CUDA handles back to their owning shared_ptr (via weak_ptr), enabling reconstruction of Python objects from driver-returned handles. - Extend EventBox with metadata fields (timing_disabled, busy_waited, ipc_enabled, device_id, context) accessed via get_box() pointer arithmetic, replacing cached Python-level fields. - Add event and kernel reverse-lookup registries for handle recovery. - Add Event.from_handle() and Kernel reverse-lookup integration with library-mismatch warning. - Convert _graph.py to _graph/ package (rename only, no content changes). Closes NVIDIA#1317 (partial) Made-with: Cursor
