BFE EngineeringandClaude Opus 4.8
289ce7f42f
Registered a 3rd repo-scoped runner on bfe-mpc-0640 (label warden-sdk, bfe-mpc-0640-warden-sdk) per ADR-0004. It is offline pending the sudo-gated steps (service install + CPUQuota/MemoryMax cgroup cap + toolchain/python provisioning), documented in docs/ci-cd.md as a [maintainer] handoff. kernel-build stays dispatch-gated and passes JOBS=4 as a belt-and-braces resource bound.

# CI/CD
|
|
|
|
`.github/workflows/ci.yml` — everything portable runs on GitHub-hosted
|
|
`ubuntu-latest`; only the heavy kernel build uses the self-hosted runner.
|
|
|
|
## Jobs
|
|
|
|
| Job | Runner | What it does |
|
|
|---|---|---|
|
|
| `test` | ubuntu-latest | `cargo test` (sim + config-lint) + `cargo-llvm-cov` line coverage on `sim`; outputs `passed`/`coverage`. |
|
|
| `mcdc` | ubuntu-latest | 100% MC/DC enforced on every `drivers/*/test` (gcc-14 `-fcondition-coverage`). |
|
|
| `bench` | ubuntu-latest | Smoke-runs the sim micro-benchmarks; emits ns/op trend JSON. |
|
|
| `patches-apply` | ubuntu-latest | Fetches pristine linux-6.18.46 (cached, sha256-verified) and applies `patches/*` in order. |
|
|
| `kernel-build` | **[self-hosted, warden-sdk]** | `build/build-kernel.sh` → `zImage` + `rv1106-warden.dtb`, uploaded as an artifact. Dispatch-gated until the runner is fully provisioned (below). |
|
|
| `badges` | ubuntu-latest | Renders loc/tests/coverage shields on push to `bringup` (`[skip ci]` + `paths-ignore` loop guard). |
|
|
|
|
## The self-hosted runner (`bfe-mpc-0640`)
|
|
|
|
A **third** repo-scoped runner instance on `bfe-mpc-0640` (alongside `flare` and
|
|
`flare-edge`), registered with the label **`warden-sdk`** as
|
|
`bfe-mpc-0640-warden-sdk`, in `~/actions-runner-warden-sdk`. The registration is
|
|
done; the following steps need **`user`'s sudo on 0640** and are not automatable
|
|
from the dev box:
|
|
|
|
1. **Install as a service** (persistence): `cd ~/actions-runner-warden-sdk &&
|
|
sudo ./svc.sh install user && sudo ./svc.sh start`. Until then the runner is
|
|
*offline* and `kernel-build` only runs when dispatched against an online runner.
|
|
2. **Resource cap** (protect the shared host): a drop-in at
|
|
`/etc/systemd/system/actions.runner.bfe-noah-warden-sdk.*.service.d/*.conf` with
|
|
`CPUQuota=400%` + `MemoryMax=6G`, then `sudo systemctl daemon-reload`. The build
|
|
inherits that cgroup. (The workflow also passes `JOBS=4` as a belt-and-braces bound.)
|
|
3. **Kernel cross toolchain**: `build-kernel.sh` needs the arm cross compiler on
|
|
PATH — set `SDK_TC` to the dir holding `arm-rockchip830-linux-uclibcgnueabihf-*`
|
|
(the Luckfox SDK toolchain, as flare-edge's runner has), or install
|
|
`gcc-arm-linux-gnueabihf` and pass `CROSS_COMPILE=arm-linux-gnueabihf-` (the
|
|
kernel is freestanding, so a generic arm cross compiler links it).
|
|
4. **`python`** (not python3): the kernel build calls bare `python`; provide a
|
|
project-local venv or a `python`→`python3` shim on the runner's PATH.
|
|
|
|
Host build deps (sudo): `dtc bc flex bison libssl-dev` (already present on 0640).
|
|
|
|
## Badges
|
|
|
|
Static shields SVGs are committed by the `badges` job (private repo can't use
|
|
dynamic shields). The GitHub-native `ci.yml` status badge works live regardless.
