# ADR 0004 — CI/CD runner: 3rd repo-scoped self-hosted runner on 0640
|
|
|
|
**Status:** Accepted (2026-08-25).
|
|
|
|
## Context
|
|
The heavy kernel/firmware build needs the SDK toolchain and Buildroot's baked-in
|
|
absolute paths — impractical on GitHub-hosted runners. flare-edge already builds on
|
|
a repo-scoped self-hosted runner on `bfe-mpc-0640` (label `flare-edge`); a repo-scoped
|
|
registration cannot be shared across repos by label alone.
|
|
|
|
## Decision
|
|
Register a **third repo-scoped runner instance** on `bfe-mpc-0640`, label
|
|
`warden-sdk` (own systemd unit `actions.runner.bfe-noah-warden-sdk.*`, own
|
|
`CPUQuota=400%`/`MemoryMax=6G` drop-in). Only the heavy `kernel-build` job uses
|
|
`runs-on: [self-hosted, warden-sdk]`; all host-testable jobs (tests, coverage, MC/DC,
|
|
benchmarks, badges, patches-apply) run on GitHub-hosted runners.
|
|
|
|
## Consequences
|
|
- Isolated from the flare backend + flare-edge CI already on that host (cgroup-capped).
|
|
- Runner setup + host build deps + the project-local `python` venv documented in
|
|
`docs/ci-cd.md`, mirroring flare-edge's.
