## Summary of Changes Hello @jhlee525, 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 TVM's Metal backend by introducing full bfloat16 (BF16) support for SIMD matrix operations. It allows for more efficient execution of BF16 computations on Apple devices running Metal 3.1 or newer. The changes include a robust mechanism to detect BF16 hardware capabilities at runtime, ensuring graceful fallback when not supported. Furthermore, the PR integrates BF16 handling throughout the compilation stack, from scheduling and intrinsic lowering to code generation, ensuring correct type emission and function calls for Metal shaders. ### Highlights * **Bfloat16 Support for Metal SIMD**: Enables efficient bfloat16 simdgroup matrix operations on Metal 3.1+ compatible hardware. * **Runtime Capability Detection**: Dynamically checks for bfloat16 support based on the target's "min_metal_version" and operating system, allowing for safe fallback. * **Comprehensive BF16 Integration**: Ensures correct bfloat16 type handling across scheduling, codegen, and intrinsic lowering stages of the compilation pipeline. * **New BF16 SIMD Intrinsics**: Registers a suite of bfloat16-specific 8x8x8 simdgroup matrix intrinsics for loading, storing, filling, and multiply-accumulate operations. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback.
