std::thread::available_parallelism merging linux/android/freebsd version by devnexen · Pull Request #120589 · rust-lang/rust

devnexen · 2024-02-02T21:53:02Z

FreeBSD 13.1 had introduced a sched cpu affinity compatibility layer with Linux. 13.0 and even 13.1 being EOL, we can simplify here.

devnexen · 2025-12-05T20:25:32Z

oh I see, the freebsd ABI had not been updated, so yes no chance to work as is.

Enselic · 2025-12-05T22:04:41Z

Ok, let's marked as S-blocked for now. Just ping when this can be tried again.

clarfonthey · 2026-09-22T01:43:11Z

Looks like this needs a rebase; what's the status of this, @devnexen @Enselic? I assume that after a year the issues have sort of settled out.

rustbot · 2026-09-22T03:47:08Z

This PR was rebased onto a different main commit. Here's a range-diff highlighting what actually changed.

Rebasing is a normal part of keeping PRs up to date, so no action is needed—this note is just to help reviewers.

clarfonthey · 2026-09-23T12:19:24Z

@rustbot author

(Going to take that as mostly a yes?)

devnexen · 2026-09-23T12:22:13Z

@rustbot ready

clarfonthey · 2026-09-23T12:36:34Z

@bors try jobs=*-freebsd

cc @Enselic if you want to do review, but since this does have tests being tier 2, I would be comfortable just merging myself if you'd prefer.

Please squash the formatting commit too. Also, not that it matters, but there's a random a at the end of d501f72

This caused a regression in Miri: rust-lang/miri#5344.

I can't yet tell if this is a Miri bug or a bug in std.
