spectrometerHBH opened a new pull request, #19657:
URL: https://github.com/apache/tvm/pull/19657
Follow-up work on top of the TIRx infrastructure bring-up (#19581).
### What's in here
- **op-dispatch**: warp ldmatrix/stmatrix copy dispatch; split CUDA copy
into reg + gmem_smem + ldgsts; tcgen05.ld/st `.16x{64,128,256}b` dispatch +
factory + M=128 layout; element-wise broadcast at the layout level + copy
vec-alignment fix
- **gemm**: CUDA synchronous `mma.sync` tensor-core dispatch; accept Layout
F C operand for M=64 MMAs
- **op**: `permute_layout` primitive (removes `permute_dims`)
- **tvmscript**: `@Tx.jit` decorator, `Tx.constexpr` params, `Tx.wg_reg_tile`
- **lower-tirx**: `Tx.device_entry()` marker replacing `ScopeKind::kKernel`;
canonical thread filters (drop `Tx.filter` wrapper)
- **codegen**: typed pointer byte-offset intrinsic; remove the
`entry_cluster_sync` codegen attribute
- **arith**: memoize IntervalSet variable relaxation; gate
canonical-simplify LT Case 2 on extra scale == +1
This batches several incremental follow-ups into one change; happy to split
into smaller PRs if that is preferred for review.
