## Summary of Changes Hello @MasterJH5574, 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 refactors the integration of FlashInfer's JIT compilation within TVM's CUDA backend. The primary goal is to streamline the compilation process by delegating it to FlashInfer's native JIT capabilities, thereby simplifying TVM's codebase and ensuring compatibility with upstream FlashInfer changes. Additionally, it improves tensor management for KV cache auxiliary data and introduces more control over the compilation output, enhancing flexibility for various deployment scenarios. ### Highlights * **FlashInfer JIT Integration Refactor**: The FlashInfer JIT integration in TVM has been updated to align with recent refactors in FlashInfer itself, leveraging FlashInfer's `JitSpec.build_and_load` for kernel compilation and removing TVM's custom compilation logic. * **Tensor Buffer Management**: Auxiliary tensors in the KV cache now enforce zero `byte_offset` fields, with the byte offset directly applied to data pointers for more efficient tensor buffer management and pointer calculations. * **Flexible Compilation Output**: A new `return_static_libs` parameter has been added to FlashInfer JIT, allowing control over whether a linked shared library or a list of compiled object paths is returned, catering to different use cases like unit tests or MLC model compilation. * **Function Name Renaming**: A new utility function `_rename_exported_func_names` has been introduced to prefix FFI-exported function names in JIT-generated source files, ensuring better organization and avoiding potential conflicts. * **MLA and Ragged Prefill Enhancements**: The MLA (Multi-Layer Attention) and ragged prefill functions now support explicit `qk_head_dim_override` and `v_head_dim_override` parameters, allowing for more flexible head dimension configurations. <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>`.
