test/hil: usbtest fleet enablement, shuffled scheduling, unique PIDs

2026-07-14T06:22:48Z

Pool/config: - record real uids (ra8m1_ek), enable usbtest for espressif s3/p4, then park ra6m5_ek and ra8m1_ek in boards-skip (ra6m5's usbtest/MSC traffic can kill the uPD720201 host on its ROM firmware; ra8m1 USBHS bring-up pending); max32666/nrf54lm20 stay enabled - their MosChip flakiness never wedges - re-enable device/usbtest on HS boards (mimxrt1064, ch32v307) now that uPD720201 firmware 2.0.2.6 fixes the command-ring death; mimxrt1015 stays skipped - its HS battery killed the controller on both ROM and 2.0.2.6 firmware (board-specific); match the moved host-test bundles (f723 <-> rt1064); skip never-passing tests on the new nrf5340dk/nrf54lm20dk boards and the detached pico host bundle, each documented with a comment Host-controller quirk gating in usbtest.py (auto-skip, self-heals on a healthy xHCI): - MosChip MCS9990 EHCI: case 25 (int-OUT never scheduled, FRINDEX bug) and case 11 (unlinked reads complete short/EREMOTEIO) - Renesas uPD720201 xHCI: firmware-gated. The card must run firmware >= 2.0.2.6 (RAM-uploaded - it reverts to ROM on every power cycle): on older firmware the command ring dies under unlink stress (a Configure Endpoint command stops completing; the hub worker deadlocks holding the device lock; only a host power cycle recovers; three boards reproduced it). usbtest.py reads the FW version register (PCI config 0x6c) and refuses to run at all on older firmware - hil_test surfaces that as a failed test with the reason. On current firmware the full 30-case battery runs (validated FS+HS: metro_m4, f723, f723-DMA all 30/30). Scheduling (hil_test.py): - Shuffle each (board, variant)'s test order with a seeded RNG (HIL_SHUFFLE_SEED to replay) so usbtest batteries and flash churn spread across the timeline instead of convoying on one controller. - Per-controller usbtest + flash semaphores: HIL_USBTEST_PARALLEL (default 4) concurrent usbtest batteries and HIL_FLASH_PARALLEL (default 8) concurrent flashes per host controller. Profiled on uPD720201 firmware 2.0.2.6 across 8/1..12/8: wall time falls 22.2/14.3/12.5/10.8 min at usbtest width 1/2/3/4 and plateaus there; zero controller errors everywhere; first battery case failures (leaf-hub bandwidth stretch) appear at 12/8, and flash width 12 only amplifies flasher-hub contention flakes - so 8/4 is the optimum. A separate battery-window flash throttle was profiled and dropped. - Give every example a unique hardcoded USB PID (0x4001-0x4022, usbtest keeps 0x4010) instead of the PID_MAP interface bitmap: different examples now always re-enumerate back-to-back, even on boards whose CPU reset does not drop D+ (WCH CH58x), so the EXAMPLE_PID table and same-PID adjacency reordering in hil_test.py are gone; only the variant-boundary same-example repeat needs a swap. - Report matrix: stable columns with the metric-bearing tests pinned first (usbtest, cdc_msc_throughput, msc_file_explorer[_freertos]), the rest alphabetical. Fail fast: - enum wait budget 8 s on the first attempt, 4 s on retries; dfu waits are deadline-based so dfu-util's own runtime counts against the budget. A device-absent failure now costs ~3-5x a passing test (20-30 s) instead of 10-30x (47-150 s). - CI runs hil_test with --retry 1 and no in-run second pass: a broken fixture fails the job fast instead of holding the self-hosted runner for hours and blocking other PRs' HIL jobs. hil_test still writes the .skip sidecar, so a manual re-run attempt only retests what failed. Review fixes (multi-agent adversarial review of this commit): - tinyusb_win_usbser.inf: the PID rework moved five CDC examples onto even PIDs the INF's odd-only DeviceList never matched (legacy-Windows usbser binding) - appended 0x4006/4008/400a/4020/4022 to both lists. - usbtest example: USBTEST_TIER is now overridable and the descriptors and pumps are tier-conditional, so a board whose DCD cannot serve a tier lowers it instead of skipping the whole example - RA2A1 (RUSB2 with no isochronous pipe) builds at tier 3 via its BOARD_ define; the host battery follows the tier advertised in bcdDevice. Tier-4 output verified byte-identical after the refactor. - dynamic_configuration's second config derived USB_PID + 11 = 0x4018, colliding with net_lwip_webserver - now USB_PID + 0x0100, outside the per-example space. tools/check_example_pids.py (pre-commit hook) enforces PID uniqueness incl. derived and literal idProduct values. - usbtest.py firmware gate: matched by device ID (uPD720201/720202, both use the 0x6c FW register), and an unreadable version (setpci missing/denied) now refuses with its own message instead of masquerading as "firmware 0x00000000"; noted the gate is necessary but not sufficient (board-specific kills stay per-board skips). - hil_test: deadline waits use time.monotonic(); multiprocessing context pinned to fork (raw semaphores in Pool initargs); flash and usbtest permits unified into one fail-closed, exception-safe ctrl_permit (unknown controller takes every slot and logs a warning instead of silently borrowing slot 0); an all-skipped battery reports as skip, not "0/0" failure; slow-body polls (mtp, printer, disk read) go through a shared deadline-based wait_until so their bodies count against the enum budget; throughput's FS detection compares serials case-insensitively like every other walk; a missing MSC read-speed line now fails the host msc_file_explorer test instead of passing with an empty metric. Hardening: - fail fast (15 s) when a driver-registry sysfs write blocks: a wedged device otherwise turns every subsequent battery into an unkillable D-state writer and silently hangs the whole run - usb-recover skill: a VM reboot is not a reliable cure (MosChip hubs latch up across the PCIe reset); full host power cycle is Co-Authored-By: Claude Fable 5 Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg

docs: add build-doc tooling and a README for every example

2026-06-29T03:16:25Z

Documentation tooling: - Add the `build-doc` skill and `tools/build_doc.py` wrapper for local Sphinx builds (clean / -W / open). - Enable Markdown (MyST) in conf.py and auto-collect examples/{device,host,dual}/*/README.md into a 3-level Examples nav (Examples > Device/Host/Dual > example), noting each page's source location and normalizing headings to a single H1. - Remove the stale `.claude/commands/build-doc.md`; point the AGENTS.md Documentation section at the skill. Example docs: - Add a README.md for every device/host/dual example: what it does, USB interface table, notable tusb_config.h settings, generic CMake + Make build steps, and how to try it. - Fold each *_freertos variant into its base README, noting the FreeRTOS source path and any RTOS-specific behavior. Generated docs/examples/ output is git-ignored. Builds clean with `sphinx-build -W`. Co-Authored-By: Claude Opus 4.8 (1M context)
