Every worker that touched the poisoned node blocked uninterruptibly, the pool could not be joined, map_async discarded every board's result, and the job ran to the GitHub ceiling with no report at all -- while the self-hosted runner's single job slot stayed occupied and every queued job waited behind it. Bound the calls a worker makes itself. read_sysfs, bounded_open and run_cmd all answer within a wall clock; read_sysfs distinguishes "absent" from "unknown", because a blocked read is not evidence of absence, and caps stranded readers at four (each costs a thread and an fd for the life of the process) after which the worker declares itself blind. mtype, the gio unmount, the libmtp session and the arecord/iperf reaps go through those bounds; the MTP session runs in a disposable subprocess, since libmtp's ctypes calls block unkillably in D state. Bound the run. A pool guard (HIL_POOL_TIMEOUT, 60 min) fires before any job ceiling and still writes a report. When the pool will not shut down, the sweep kills what the workers spawned -- descendants, not just direct children, since flashers run in their own session -- confirms each kill actually landed, and exits early so the runner is freed. Whatever survived is named in the report. Deliberately shallow past that point. We do not re-scan process groups, prove pid ownership, or escalate through sudo: a root-owned survivor is reported, not force-killed, because signalling a pid we cannot prove is ours is the worse failure, and the job ceiling backstops whatever this misses. A D-state holder was never killable anyway. Recover instead of reporting a wedge. A HUNG usbtest case reflashes its own DUT through its roster flasher, but only where the flasher can reach its probe past a poisoned node -- openocd pinned to a validated vid_pid, or esptool. Where it cannot, the run says so rather than reserving budget for a path that cannot fire. Raise the CI ceilings above the pool guard so the guard fires first and still writes its report, and pin --retry 1 on every HIL leg: the guard is a flat constant and does not scale with max_retry, so argparse's default of 3 would triple the serialized usbtest tail against an unchanged guard. Split the module: execution in hil_test/hil_flash/usbtest, infrastructure in helper/ (locking, health, selection, shared bounded IO), and the two matrix generators into .github/scripts/ -- ci_set_matrix.py sat in workflows/, where GitHub treats every file as a workflow definition. 193 tests cover the bounded paths, the kill ladder, the guard and the selector against synthetic /proc trees and PATH-injected fakes; a real wedge cannot be manufactured on demand. 2026-08-17T12:04:37Z Ha Thach thach@tinyusb.org 2026-08-17T12:04:37Z urn:sha1:2465ea8f435114af3b3c935cc4fbed423d9eac69 Fix HFP HIL reliability issue 2026-07-31T16:17:36Z Ha Thach thach@tinyusb.org 2026-07-31T16:17:36Z urn:sha1:f3021b337fcea154b898489c417d428c92f88e92 test/hil: one openocd flasher, per-board verify and firmware extension The four WCH boards move to `openocd`, leaving one flasher for all. `verify` is now a per-board opt-out, not dropped fleet-wide: WCH cannot read flash back over the WCH-Link sdi transport; the other seven openocd boards can, and say so explicitly. FLASHER_SUFFIX decides each flasher's extension once — find_firmware returns the full path and the flashers pass it through, so a build with only the wrong artifact is skipped rather than failed mid-flash. --skip-flash bypasses the filter. rescue_openocd() power-on-resets a wedged RP2040/RP2350 via its Rescue DP from the flash retry; the probe has no reset line. Drops unused openocd_adi, stflash, wlink_rs and uniflash, parks the unstable ra6m5_ek, and tests that every roster flasher name dispatches. 2026-07-29T19:35:02Z hathach thach@tinyusb.org 2026-07-29T19:35:02Z urn:sha1:6271842ea874812f1157b42bcd650c59ab59259b 2026-07-29T19:29:32Z Ha Thach thach@tinyusb.org 2026-07-29T19:29:32Z urn:sha1:eef5af86aa26fe3d72e41156a586a6ed3ffce9f8 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. 2026-07-29T14:08:26Z Zixun LI admin@hifiphile.com 2026-07-29T14:08:26Z urn:sha1:1b628e3fb581d56639fac9287448203db7d10ff1 2026-07-29T10:29:59Z Ha Thach thach@tinyusb.org 2026-07-29T10:29:59Z urn:sha1:e88fc441ddcaaa5abd4f4673ef2bf29499522dc0 test/hil: add board-pool health check, split hil_test into focused modules (#3794) Add test/hil/hil_pool_check.py: per-board rig health scan — probe presence, light-example flash (dfu_runtime; device_info + serial check for host-only boards), uid re-enumeration, safe recovery (probe authorized-toggle, board reset), verified board_test re-park, USB topology report, and a markdown summary table. Missing firmware is built on the spot (tools/build.py, idf.py for espressif, one get_deps retry); row statuses: ok, flash-failed, failed, locked. Board locks are always respected, never bypassed. Refactor hil_test.py into hil_lock.py (flock protocol, controller permits, hold/release/status CLI; replaces board_lock.py) and hil_flash.py (flashers, find_firmware, run_cmd). Update WCH probe uids and the board roster in tinyusb.json; add the hil-pool-check skill. 2026-07-28T22:41:26Z Zixun LI admin@hifiphile.com 2026-07-28T22:41:26Z urn:sha1:a7d778c68e46c6013a39d8520c176a3592fc0cd7 2026-07-28T22:35:21Z Zixun LI admin@hifiphile.com 2026-07-28T22:35:21Z urn:sha1:192e0bd872608b4a39b36047e0d5c1d18c2a8f02 2026-07-28T21:27:54Z Zixun LI admin@hifiphile.com 2026-07-28T21:27:54Z urn:sha1:b868d6d268cab403eb843f3d0a190162a4e5d0db
