hil: controller-aware scheduling of flash and usbtest concurrency

2026-07-17T04:54:14Z

Full-fleet profiling (HIL_PROFILE=1 instrumentation, included) showed each uPD720201 controller's serialized usbtest battery chain dominates wall time, and a board whose marginal device port bounces during concurrent batteries can wedge or kill the controller ("xHCI host not responding to stop endpoint command"). Every such death traced to mimxrt1015's port (its old "kills the uPD720201" reputation) - it is removed from the config until recabled; mimxrt1064's enum-retry stalls were a loose device cable (re-seated). nrf54lm20dk moves to boards-skip until its failing J-Link probe is replugged. With the hardware fixed both cards run width-4 batteries plus full flash churn clean, so scheduling stays simple: two symmetric knobs, flashes and batteries budgeted per controller. - schedule_boards(): dispatch boards round-robin across host controllers from a persisted hint cache (~/.cache/tinyusb-hil/ctrl_cache.json), learned and merge-on-write refreshed each run (concurrent HIL jobs keep each other's entries). Only the cached PCI address is consumed - dispatch order and first-flash budgeting, never battery serialization (batteries resolve live or fail closed to an all-slot permit). - HIL_FLASH_PARALLEL (8) and HIL_USBTEST_PARALLEL (4) are budgeted per controller via lock slots assigned on first sight. - re-runs: a failed run writes /.failed with the exact re-run spec (--accumulate -b -bt :) instead of the inverted --skip-board list of everything that passed; --skip-board is gone, --flasher/--exclude-flasher scope a config across CI jobs by flasher type (no board names hardcoded in workflows), and -a/--accumulate merges a re-run into the existing report. The spec is stamped with GITHUB_RUN_ID and cleared on fresh runs, so a retry can never consume a spec left behind by a different run's dead or skipped attempt. - CI: esp-idf firmware builds move out of hil-build into hil-build-esp, and the esptool-flashed boards run in their own hil-tinyusb-esp job, so the main hil-tinyusb run starts as soon as the fast toolchains finish instead of waiting on the slow esp-idf build (an esp toolchain flake previously skipped the whole rig run). Artifacts are namespaced per toolchain so the esp job downloads only esp-idf binaries. - HIL_PROFILE=1: timestamped log lines, per-flash durations, permit-wait logging, uid->controller map dump for analysis. - hil_report: per-variant test duration as a dedicated trailing column, recorded only by full runs. Validated on the ci rig (fixed seeds 20260716/777, full fleet at 8/4): 738s/780s walls with only known-flake failures and no controller deaths, vs 1134-1211s serialized-battery baseline.
