I think the default constructors like this are deprecated. Please check that. I see this in a few examples.

Thanks, fixed in the split benchmarks/examples PR: #23697. I replaced the nullary cuda::stream_ref{} uses in the examples with explicit cuda::stream_ref{cudaStreamLegacy}.

I think you want cudaStreamDefault and not cudaStreamLegacy. We should respect compiling with PTDS enabled, which changes how cudaStreamDefault is interpreted.

This file appears to be missing <cuda/stream> includes. Same for cpp/src/ast/jit/expressions.cpp and others in cpp/src/ast. Can you check everything for IWYU?
There was a problem hiding this comment.
Done here. I audited the AST/JIT changes and added direct <cuda/stream> includes where cuda::stream_ref is used, including this file and the corresponding AST/JIT implementation files.

Follow-up: I found one remaining IWYU miss while rechecking this thread: cpp/include/cudf/ast/expressions.hpp also declares cuda::stream_ref and was still relying on transitive includes. Fixed in 5ab1aa5855 by adding a direct <cuda/stream> include there as well.

Done here. This now uses an explicit legacy stream construction: cuda::stream_ref{cudaStreamLegacy}.

This should be explicit and not default-constructed. But should it be set to cudaStreamLegacy or cudaStreamDefault? Probably Legacy?

Done here. I used the explicit legacy/default-stream spelling for the non-PTDS case: cuda::stream_ref const default_stream_value{cudaStreamLegacy}.

There are a few files like this with header changes but no changes in the code itself. I don't think the header is used. Can we audit for those files and remove the headers if they're not required?
There was a problem hiding this comment.
Done in the split tests PR: #23696. I audited the test-only header additions and removed the unused stream headers.

Check the returned status from all asynchronous CUDA memory operations.
Both files pass the migrated native stream handle correctly, but both discard CUDA errors.

Check the CUDA kernel launch.
The changed launch does not check its CUDA error status. Add CUDF_CHECK_CUDA(0) after the loop so ForkStreams reports launch failures.

Description
This fifth batch migrates the remaining core libcudf and libcudf_streaming headers and implementations from
rmm::cuda_stream_viewtocuda::stream_ref.It includes the final central stream utility API updates, such as the default stream and stream pool helpers, while keeping
rmm::cuda_streamownership unchanged. It also includes the matching C++ test, benchmark, example, developer-documentation, and streaming binding updates needed for this API change to build cleanly in CI.Contributes to #23636
