  "message": "[LinalgExt] Add topk_v2 op with roundtrip and invalid mlir test (#24054)\n\n**Context**: Refer to [Discord\ndiscussion](https://discord.com/channels/689900678990135345/1491812950451814540)\nfor the design choice. We aim to add a top-K op with bitonic sort\nvectorization along the VectorDistribute pipeline. Refer to Issue:\nhttps://github.com/iree-org/iree/issues/24053 for more details.\n\nThis PR, as the first step, defines the` iree_linalg_ext.topk_v2`\noperation and defines its verifier along with corresponding roundtrip\nand invalid tests (`roundtrip.mlir` and `invalid.mlir`).\n\nSupport for topk_v2 will be added incrementally across multiple PRs: \n\n- Add the `iree_linalg_ext.topk_v2` op definition and verification\nlogic, along with roundtrip and invalid IR tests (this PR)\n- Add tiling support\n- Add convert_to_loops lowering support\n- Add e2e support along the VectorDistribute pipeline (vectorization,\nlayout analysis, and distribution, etc)\n\n---------\n\nSigned-off-by: Bangtian Liu \u003cliubangtian@gmail.com\u003e",
