test/hil, ci: contain a wedged USB stack instead of stranding the runner

2026-08-18T05:19:09Z

A wedged USB device used to take the whole HIL run with it. 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.

hil, ci: scope HIL builds and tests to the boards a PR affects (#3797)

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.

remove IAR toolchain support from make build system

2026-04-06T04:17:34Z

IAR is only supported with CMake. Remove all IAR-specific references from the Make build system including toolchain files, SRC_S_IAR, LD_FILE_IAR variables, and IAR toolchain detection. Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and broken formatting in stm32f7 board_uart_write. Co-Authored-By: Claude Opus 4.6 (1M context)
