📝 Walkthrough

Summary by CodeRabbit

• New Features
  • Added support for the numba-cuda-mlir package in CUDA 12.9 and 13.3 environments across supported architectures.
  • Included numba-cuda-mlir as a runtime dependency for cuDF packages.
• Chores
  • Updated dependency configuration to apply the package requirement consistently across conda environments and builds.

Walkthrough

The change adds numba-cuda-mlir>=0.3.0 to shared conda dependencies, the cuDF conda recipe, and CUDA 12.9 and 13.3 environment specifications for AArch64 and x86_64.

Changes

Numba CUDA MLIR dependency

Layer / File(s)	Summary
Shared dependency definitions dependencies.yaml	The conda dependency anchor now provides numba-cuda-mlir>=0.3.0. The CUDA-unsuffixed fallback reuses the anchor.
Recipe and environment specifications conda/recipes/cudf/recipe.yaml, conda/environments/all_cuda-129_arch-*.yaml, conda/environments/all_cuda-133_arch-*.yaml	The cuDF runtime requirements and all CUDA 12.9 and 13.3 architecture environments now include numba-cuda-mlir>=0.3.0. The obsolete availability TODO was removed.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to f77d9

This is a localized dependency and environment metadata update. No actionable merge-blocking risk remains beyond normal checks and review.

Add coverage for the new dependency branches.

This cohort changes dependency generation but includes no unit tests or unit benchmarks. Add unit tests for the conda output, the CUDA 12 and CUDA 13 pip outputs, and the cuda_suffixed: false fallback. Assert package, version-floor, and selector semantics. Add unit benchmarks for the dependency-generation path.

As per coding guidelines: **/*: 6. Add unit tests and unit benchmarks.
