Build

Copy scx into a workspace checkout and build there. Scheduler behavior is documented in scx/README.md. The installer pins upstream e7b3a219617472cf78880ac424714e52c932db61.

sudo bash tools/install_scx_flow.sh /tmp/scx-workspace
/usr/local/bin/scx_flow --version

Expect the current version, state enabled, ops with flow.

This scheduler needs a restart from prior releases with no live transition. Queue ids, slice, dispatch order, and stats follow this scheduler, see scx/README.md.

Checks

cargo fmt --check
cargo clippy --all-targets -- -D warnings
cargo test

Run from inside the workspace so path deps resolve.
