## Summary of Changes Hello @tqchen, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly enhances the TVM FFI Python binding by introducing a generic value protocol. This new protocol empowers Python classes to define their own conversion logic for FFI compatibility, making the system more extensible for custom data types. The changes also include a substantial refactoring of the FFI call context's memory management, specifically optimizing how temporary Python objects are handled during argument processing. These improvements ensure robust and efficient interaction between Python objects and the FFI, supported by new tests and updated benchmarks. ### Highlights * **Generic Value Protocol Introduction**: Introduced a new generic value protocol (`__tvm_ffi_value__`) that allows Python classes to declare how they should be converted into TVM FFI-compatible values, enhancing flexibility for custom types. * **FFI Call Context Refactoring**: Refactored the `TVMFFIPyCallContext` and `TVMFFIPyCallManager` in `tvm_ffi_python_helpers.h` to use a new `TVMFFIPyCallStack` class. This improves memory management for temporary Python objects, especially when handling the new value protocol, by providing a dedicated stack for extra temporary objects. * **New Dispatcher for Value Protocol**: Added `TVMFFIPySetArgumentGenericDispatcher` and `TVMFFIPyPushExtraTempPyObject` to support the new value protocol, ensuring proper handling and lifetime management of intermediate Python objects during argument conversion. * **Expanded Test Coverage**: Added new test cases in `test_function.py` and `test_tensor.py` to validate the `__tvm_ffi_value__` protocol, including scenarios with nested value protocols and Python `NamedTuple` objects. Benchmarking scripts were also updated to include NamedTuple arguments. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
