## Summary of Changes Hello @guoyuhong, 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 introduces a critical enhancement to the `_get_cuda_target` function, addressing a common issue where NVIDIA Ampere-generation GPUs with older drivers fail to report their compute capability. By implementing a fallback mechanism that queries the GPU name and maps it to known compute capabilities, this change significantly improves the reliability of GPU detection, ensuring that SGLang and TVM-FFI can correctly configure for these devices. ### Highlights * **Improved GPU Detection**: Implemented a fallback mechanism in `_get_cuda_target` to correctly identify CUDA compute capabilities for NVIDIA Ampere GPUs (e.g., A10, A100) when `nvidia-smi`'s `compute_cap` field is not available due to older drivers. * **GPU Name Mapping**: Utilized `nvidia-smi --query-gpu=name` to retrieve the GPU name and mapped specific Ampere GPUs (A100 to 8.0, A10 to 8.6) to their corresponding compute capabilities. * **Enhanced Compatibility**: Ensured robust GPU detection and backward compatibility for Ampere devices running legacy NVIDIA drivers, preventing errors related to auto-detection failures. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <details> <summary><b>Changelog</b></summary> * **python/tvm_ffi/cpp/extension.py** * Added a `try-except` block to handle cases where `nvidia-smi` does not provide `compute_cap`. * Implemented logic to query GPU name using `nvidia-smi --query-gpu=name`. * Mapped "A100" to compute capability 8.0 and "A10" to 8.6. * Included an exception for unsupported GPU names in the fallback. </details> <details> <summary><b>Activity</b></summary> * The pull request was created by guoyuhong to address an issue with NVIDIA Ampere GPU detection. </details> <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>`.
