  "message": "[DT] Collapse matmul_narrow_M/N field into round_dims_to attribute. (#18599)\n\nThe revision refines how we handle matmul_narrow_M/N in encodings. The\r\nmatmul_narrow_M/N attributes are retired in the patch. The information\r\nis carried in `round_dims_to` attribute which is rounded to the next\r\npower of two. E.g., if the value of `matmul_narrow_M` is `3`, it will be\r\n`4` in the `round_dims_to` attribute.\r\n\r\nThe `kNarrowThreshold` constant is introduced to Encoding namespace. A\r\ndimension is considered as \"narrow\" only if the size of the dimension is\r\nless than `kNarrowThreshold`.\r\n\r\nThe revision implements `getMatmulNarrowM` and `getMatmulNarrowN`\r\nhelpers based on the definition of `round_dims_to` and the\r\n`kNarrowThreshold` variable. Users can call the helpers to get the\r\nnarrow size of M/N. Again, you\u0027ll get the value that is rounded to the\r\nnext power of two if they are considered \"narrow\". E.g.,\r\n`getMatmulNarrowM()` returns `4` if `M` equals to `3`.\r\n\r\nThe revision also fixes a bug in `chooseMatmulTile` on CPU side. The\r\nhostDefinedUpperBound is not updated in the narrow-N cases.\r\n\r\nFixes https://github.com/iree-org/iree/issues/17729\r\nFixes https://github.com/iree-org/iree/issues/15466\r\n\r\n---------\r\n\r\nSigned-off-by: hanhanW \u003chanhan0912@gmail.com\u003e",
