2026-07-14test/hil: usbtest fleet enablement, shuffled scheduling, unique PIDshathach
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 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg
2026-06-18examples/uac2: drop redundant entity_id check in request helpershathach
The audio20 get/set entity dispatchers already extract entity_id from wIndex and route to the matching clock / feature-unit helper, so each helper's own entity_id re-derivation and TU_ASSERT(entity_id == ...) was dead: the helper is only ever reached for its one entity. Unknown entities are still rejected by the dispatcher's "not handled" path. Remove the redundant local, the dead assert, and the constant "entity" field from each helper's not-supported log (the message text already identifies the entity). The local is dropped entirely rather than kept for the log, since TU_LOG1 compiles out in release and would leave it unused. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
