metrics: replace the linkermap CI pipeline with membrowse

2026-09-06T08:57:00Z

Membrowse becomes TinyUSB's size-analytics system, in CI and locally. .github/membrowse-targets.json names the boards CI builds per family and the drivers each covers; a checker enforced by pre-commit fails when a dcd/hcd driver (plus ehci/ohci) is neither claimed nor documented in `uncovered`, validates board and family names against hw/bsp, and requires a board claiming an hcd driver to build at least one host/dual example. tools/build.py resolves that file into the build matrix and gates uploads on it. Locally, tools/membrowse_compare.py diffs `membrowse report --json --all-symbols` per source file, keyed on object_file (membrowse 1.2.9 truncates source_file to a basename), and metrics_compare_base.py uses it as the default engine, with `--engine linkermap` as the legacy map.json fallback (still required for --combined/--ci). A guard errors instead of writing a silent all-zero table when the filters match nothing. linkermap stops running on every build: the POST_BUILD hook goes, the explicit -linkermap target and a new examples-linkermap aggregate stay, and family_add_linkermap() no-ops when the dep is not fetched. CI loses the whole linkermap pipeline - the code-metrics job, the sticky PR size comment, release metrics assets, per-family artifacts, metrics_pair_compare.py, the membrowse-onboard workflow and CircleCI's dead tinyusb_metrics lane. The cmake job builds the named boards (esp-idf included, membrowse wired into the IDF docker path via family_initialize_project and MEMBROWSE_LD_OVERRIDE) and uploads only those, keeping the --identical path for code-unchanged runs. ci_select follows: the size tooling no longer runs in any CI build, while the board list decides what a family's legs compile and so forces a full matrix. Adds the espressif, same7x, cxd56 and f1c100s families the board list needs, each build-verified. The upload itself moves out of cmake: family_add_membrowse()'s ~90-line inline bash becomes tools/membrowse_report.py, carrying ninja linker-script extraction with recursive INCLUDE resolution, --defsym collection, map-file detection, --identical fallback and upload composition. The API key is read from the environment at run time, passed via argv and redacted in logs - nothing is baked into build.ninja at configure time, which the CMake-expanded $ENV{MEMBROWSE_API_KEY} used to do. tools/membrowse_onboard.py wraps `membrowse onboard` for history backfill, deriving the build script, elf path and the CI-matching target name (/) so a backfill cannot land under a name CI never uploads to; it refuses to start on a dirty worktree, since onboard checks out past commits in place. A membrowse skill documents local reports, size diffs, board-list maintenance, uploads and backfill; the code-size skill records the new default engine and its linkermap fallback. Three follow-up handoffs capture what was deliberately split out: full linkermap removal, membrowse --combined support, and the dead build_filtered plumbing.

hil, ci: scope HIL builds and tests to the boards a PR affects Add test/hil/hil_select.py, a stdlib-only selector that maps a PR diff to the rig boards, tests and BSP families a change can affect, and wire it into CI so pull requests build and run only those. A port change picks its families' boards, a class change picks the examples enabling that class, and device/host changes prune the other role. Anything unclassified — infra, an unmapped port, a selector error — falls back to the full matrix, and push/schedule runs are untouched. Move the shared example lists to hil_examples.py; 54 hardware-free tests cover the rules.
