https://discourse.llvm.org/t/rfc-add-xegpu-dialect-for-intel... : > XeGPU dialect models a subset of Xe GPU’s unique features focusing on GEMM performance. The operations include 2d load, dpas, atomic, scattered load, 1d load, named barrier, mfence, and compile-hint. These operations provide a minimum set to support high-performance MLIR GEMM implementation for a wide range of GEMM shapes. XeGPU dialect complements Arith, Math, Vector, and Memref dialects. This allows XeGPU based MLIR GEMM implementation fused with other operations lowered through existing MLIR dialects. |
