ci: add riscv64 wheel builds#506
Conversation
Add a build_wheels_riscv64 job using cibuildwheel with QEMU emulation. Targets CPython 3.10-3.14 (including free-threaded) on manylinux_riscv64. Skips musllinux (no riscv64 image available). Higher timeout (120 min) to account for QEMU + Rust compilation overhead. Closes openai#502

Native build verified on riscv64 hardware (BananaPi F3, SpacemiT K1, rv64gc, GCC 14.2.0): SUCCESS. |

maybe use a pinned version as other jobs do?

@justeph Done. Pinned all four actions in the riscv64 job (checkout, setup-qemu-action, cibuildwheel, upload-artifact) to commit hashes, matching the pattern used in the other jobs.

Any chance to get this merged? For reference, I forked @gounthar branch into my namespace to run the workflow, and it succeeded in 23 mins. See https://github.com/justeph/tiktoken/actions/runs/25152519227. Is that acceptable? |
Mirror the pinning pattern used in build_wheels and build_wheels_aarch64. Signed-off-by: Bruno Verachten <gounthar@gmail.com>

A tested riscv64 wheel is available in our community index:
https://gounthar.github.io/riscv64-python-wheels/simple/tiktoken/
Built natively on BananaPi F3 (SpacemiT K1, rv64imafdcv, 8 cores @ 1.6 GHz, 16 GB RAM).

Note: this work is part of the RISE Project effort to improve Python ecosystem support on riscv64 platforms. Native riscv64 CI runners are available for free via RISE RISC-V runners.
