Endpoint completions are drained per interrupt with RX serviced before TX, so a SETUP is never passed over in favour of a stale IN completion, and an EP0 IN transfer is only flushed on SETUP once it has actually finished. The block has no equivalent of the CH569's RB_USB_INT_BUSY, so a SETUP that arrives while a transfer completion is still unserviced gets no handshake at all. A SETUP may not be NAKed or STALLed, so the host retries and then fails the transfer. docs/superpowers/notes/h417-ep0-diff.md records the measurements and the usbtest cases quirked as a result. --- src/portable/wch/ch32h417_usbhs_reg.h | 39 ++ src/portable/wch/dcd_ch32h417_usbhs.c | 661 ++++++++++++++++++++++++++ 2 files changed, 700 insertions(+) create mode 100644 src/portable/wch/ch32h417_usbhs_reg.h create mode 100644 src/portable/wch/dcd_ch32h417_usbhs.c diff --git a/src/portable/wch/ch32h417_usbhs_reg.h b/src/portable/wch/ch32h417_usbhs_reg.h new file mode 100644 index 0000000000..f1ae1ed712 --- /dev/null +++ b/src/portable/wch/ch32h417_usbhs_reg.h @@ -0,0 +1,39 @@ +/* + * SPDX-FileCopyrightText: Copyright (c) 2026 Ha Thach (tinyusb.org) + * SPDX-License-Identifier: MIT + * + * This file is part of the TinyUSB stack. + */ + +#ifndef USB_CH32H417_USBHS_REG_H +#define USB_CH32H417_USBHS_REG_H + +// USBHSD_TypeDef (device block @0x40030000) and USBHS_* bit macros come from the SDK. +#pragma GCC diagnostic push +#pragma GCC diagnostic ignored "-Wstrict-prototypes" +#include "ch32h417.h" +#include "ch32h417_usb.h" +#pragma GCC diagnostic pop + +// The per-endpoint registers are named fields in USBHSD_TypeDef, not arrays: reach EPn from EP0 +// by pointer arithmetic.

Get it enumerating on + hardware before touching USB3. +3. **USB3 dcd** (`SPEED=super`) — one file. Structure it like `dcd_ch56x_usb30.c`: + - `link_*` static functions for the LTSSM/LMP work, isolated from the endpoint + engine (this is the extraction seam if a sibling chip shares the link IP — e.g. + CH32H417 shares the CH569 LINK block but has a different endpoint engine). + - All link/LMP register work happens **in the ISR** (timing critical, µs budgets); + only `dcd_event_*` calls defer to task context. + - "Bus reset" for the stack = the link first reaching U0 + (`dcd_event_bus_reset(rhport, TUSB_SPEED_SUPER, true)` after the LMP exchange starts). + - SET_ADDRESS applies at the **status stage**, not when the request arrives. + - DMA constraints (dedicated RAM regions, alignment) → per-endpoint bounce slots from + a small pool; zero-copy only when the app buffer qualifies. +4. **Runtime fallback** (single rhport, `SPEED=super` default) — a hardware timer bounds + SS training; expiry tears USB3 down and brings the USB2 controller up on the same + rhport; usbd re-inits transparently on the USB2 bus reset.

Both then drive the real toggle from software (`ep0_tog` / `ep0_rx_tog`) when +arming, so the register value at SETUP time is mostly vestigial -- but it is a difference. + +**4. Interrupt-flag bookkeeping.** CH569 explicitly clears `R8_USB_INT_FG` in every branch. +H417's TRANSFER branch clears only the per-endpoint DONE bits, which is correct for this +part (`RB_UDIF_RTX_ACT` is RO, RM 25.2.1.8) and **not** a portable difference. + +### Candidates, highest expected impact first + +### C1: remove the ISR status pre-arm +- CH569 does: nothing -- EP0 RX stays NAK until usbd submits the status stage; 30/30. +- H417 does: `ep0_rx_tog = true; arm_ep0_out();` in `update_in`'s EP0 completion. +- Change: delete the pre-arm and the `ep0_status_out_early` latch it requires. +- Prediction: if the pre-arm is not what makes H417 work, the drop rate is unchanged and + the code loses four separate defects at once (review findings 3, 9, 10, 14 all exist + only because of it). If the drop rate worsens materially, the pre-arm is load-bearing + and the findings must be fixed individually instead. +- Portable? Yes -- removal, toward the oracle. +- Note: its original justification (63% -> 37%) came from single ~90-SETUP captures, the + method later shown to span a 27-point band on one unchanged build. It is unproven. + +### C2: SETUP-branch toggle to DATA0 +- CH569 does: `EP_TX_CTRL(0) = UEP_T_RES_NAK` (toggle bits 0). +- H417 does: `EP_TX_CTRL(0) = USBHS_UEP_T_RES_NAK | USBHS_UEP_T_TOG_DATA1`. +- Change: drop the `| TOG_DATA1` from the SETUP branch's TX write. +- Prediction: probably neutral -- `queue_in_packet` sets the real toggle from `ep0_tog`. +- Portable? Yes. + +### C3 (review #4): SETUP must not destroy a co-pending EP0 IN completion +- H417 does: `xfer_status[0][TUSB_DIR_IN].valid = false` plus a full-byte TX write that + clears a pending `RB_UEP_T_DONE`, so the previous transfer's status-IN completion is + never delivered and `CONTROL_STAGE_ACK` never fires (drops HID SET_REPORT payloads). +- Change: service a pending TX completion before resetting the pipe, or reset only the + OUT side. +- Portable? Yes. Independent of C1. + +### C4 (review #12): reset the new module-level flags in `ch32h417_usb2_init` +- H417 does: never assigns `sof_enabled`, `bus_suspended`, `ep0_status_out_early`; the + bus-reset branch misses `sof_enabled`. A stale latch emits SOF events usbd never asked + for, which `usbd.c` turns into a fabricated RESUME that cancels a real suspend. +- Change: zero all three in init; add `sof_enabled` to the bus-reset reset. +- Portable? Yes. Independent of C1. Cheap and clearly correct. + +### C5 (review #13): forward the caller's ISR context +- H417 does: `dcd_event_xfer_complete(..., false)` hardcoded in the early-status path, and + the USB3 dispatcher drops `is_isr` before reaching the USB2 back end. +- Change: thread `is_isr` through, as `dcd_ch32h417_usb30.c` already does. +- Portable? Yes, but moot if C1 removes the early-status path entirely. + +### Cross-check against spec Appendix A + +None of C1-C5 duplicates a refuted row. Appendix A rules out gating SETUP detection on +`!valid` or on `EP_RX_LEN(0) == 8`, making `arm_ep0_out()` preserve DONE, dropping the +forced DONE write-back, `USBHS_UDIE_SOF_ACT`, re-latching `UEP0_DMA`/`UEP0_MAX_LEN`, and +clearing `RB_UEP_x_NAK_ACT`. C1 *removes* the construct that two of those rows tried to +patch, which is a different move from patching it again. + +Review findings 5, 6, 7, 8 and 11 are USB3-driver defects unrelated to the HS SETUP drops +and are out of scope here; finding 15 is a unit-test ordering issue. All are recorded for +a separate pass. + +### Phase A results (2026-08-14) + +Reference baseline: **34.5%** (316 SETUPs). All measurements pooled over 5 fresh-flash runs. + +| Candidate | Pooled drop rate | usbtest (3 fresh flashes) | Kept | +| ---------------------------------- | ---------------- | ------------------------- | ---- | +| baseline | 34.5% (316) | 25/30, 24/30, 24/30 | -- | +| C1 remove status pre-arm | 32.8% (308) | 25/30 x3 | yes | +| C3+C4 correctness fixes | 37.7% (329) | 25/30 x3 | yes | + +**No candidate moved the drop rate.** 32.8 / 34.5 / 37.7% all sit inside the per-run band +(25.0-46.5% observed across the three configurations), so none of them is the mechanism. + +C1 was kept anyway: it is a *removal* that matches the oracle, is neutral on the metric, +makes usbtest more consistent (case 29 stops flapping), and deletes five review findings +whose only cause was the pre-arm. C3+C4 were kept as correctness fixes, explicitly not as +drop-rate candidates. + +**C2 (SETUP-branch toggle to DATA0) was not implemented: it is provably inert.** +`queue_in_packet` rewrites `UEP0_TX_CTRL`'s toggle from `ep0_tog` on every arm, so the +value written at SETUP time never survives to affect a transaction. Testing it would spend +rig time to confirm a no-op that can be read off the code. + +**Phase A verdict: exhausted without reaching 30/30.** Every portable difference between +the oracle and the subject has been tried or shown inert. The one structural difference +that could plausibly explain a SIE-level SETUP drop -- CH569's dedicated `RB_USB_IE_SETUPACT` +interrupt versus H417 inferring SETUP from a sticky flag inside the TRANSFER branch -- is +**not portable**: the H417 silicon has no SETUP interrupt to enable. + +Proceed to Phase B (Task 6): the unmodified vendor SDK demo as the silicon-vs-driver oracle. + +## Phase B — ABORTED: the vendor demo bricked the board (2026-08-14) + +The unmodified `SimulateCDC-HID` demo built cleanly out-of-tree (53 KB text, `.highcode` +at 0x20080000, nothing under `hw/mcu/` edited). Because the demo has no reflash backdoor +of its own, it was flashed with a shim (`/tmp/vendor-oracle/loader_shim.c`) grafting the +BSP's USART1 magic matcher and UART flash loader onto it, keeping the vendor USB sources +bit-for-bit unmodified. + +**The shim did not work.** The image flashed (57 KB) but never enumerated, produced no +UART output, and did not answer the park magic. The board hung before the USART1 RX +interrupt could be serviced. + +Most likely cause: the vendor's `Hardware()` and `ch32h417_usbhs_device.c` call `printf()`, +and the shim deliberately skipped the vendor's `USART_Printf_Init(2000000)` to keep USART1 +at 115200 for the loader. A blocking `printf` on an unconfigured port hangs before USB init. + +Recovery required physically unplugging the Type-A cable (SDI is unusable while a host's +termination sits on PB8/PB9, `wlink` returns protocol error 0x55), then +`wlink -d 1 erase --method power-off --chip CH32H41X` and a reflash. The nano was restored +and the UART loader verified working again. + +**Do it this way next time:** flash a shim that runs ONLY the loader window and returns -- +prove the escape hatch round-trips -- and add `Hardware()` only after that. Also call the +vendor's `USART_Printf_Init()` and instead teach `wch_uart_flash.py` the vendor's baud, so +the vendor's own init sequence is left intact. + +**Also learned:** `wlink` has no default probe and will attach to whichever WCH-Link it +finds first. Always pass `-d ` (resolve with `wlink list`): probe #0 is the hydra +(D3008F0657DB, CH56X), probe #1 is the nano (E8E68F066EEE, CH32H41X). An erase issued +without `-d` targeted the hydra's probe; only the chip-type guard stopped it, and the hydra +was re-verified afterwards at 12/12 + usbtest 30/30. + +**Status: silicon-vs-driver remains undecided.** Phase A is exhausted and Phase B is unrun. + +## Task 7 — verification (2026-08-14) + +| Check | Result | +| --------------------------------------- | -------------------------------------------------- | +| usbtest, 3 fresh flashes | 25/30 each, failing 9/10/13/14/21 (acceptance NOT met) | +| HIL device suite, high speed | 11/12, CDC 5.8/6.5 MB/s, MSC 25.4/10.3 MB/s | +| CH569 HS (oracle, unaffected) | 12/12 + usbtest 30/30, verified twice today | +| ceedling unit tests | 72/72 | +| pre-commit, all files | clean | +| SuperSpeed regression | **BLOCKED** -- see below | + +**SuperSpeed could not be regression-tested and this is cabling, not code.** The run reported +0/12, but the device enumerated normally on bus 5 (USB2) as `5-2` while bus 6 held nothing and +all four SS ports read `Rx.Detect`. The usb_sniffer tap now sits between the nano and the +uPD720201; it passes D+/D- through but not the SuperSpeed pairs, so SS cannot train through it. +Independently, the HS driver contributes 0 symbols to the `SPEED=super` build (verified with +`nm`), so nothing changed in this campaign can reach the SuperSpeed path. + +To clear it: remove the sniffer from the cable path and re-run +`python3 test/hil/hil_test.py -B examples -b nanoch32h417 test/hil/local.json`, +expecting 12/12 with usbtest 29/29. + +## Phase B retry (2026-08-14) — oracle still unrun, but recovery is now free + +**The IWDG guard works and removes the bricking cost.** Arming an ~8 s IWDG kicked from a 1 ms +SysTick0, immediately before calling the vendor `Hardware()`, means a wedge with dead interrupts +resets the board straight back into the unconditional loader window. Verified: the hanging vendor +image was flashed, hung, self-reset, and was reflashed with no physical access. Any further Phase +B attempt is now safe to iterate on. The earlier boot-window-only design failed because nothing +can *trigger* a boot once the firmware is wedged. + +**Step 1 passed, step 2 still hangs.** A loader-only shim (no `Hardware()` call) booted and +reflashed itself, so the scaffolding -- linker script, startup, system file, USART1, loader -- is +sound. Adding the single `Hardware()` call kills it. The fault is in the vendor USB init, and the +unbounded `while (!(RCC->CTLR & RCC_USBHS_PLLRDY));` at ch32h417_usbhs_device.c:178 remains the +prime suspect; our driver bounds the same wait with a timeout. + +### C6: disable the SWJ pin function before USB init — NO EFFECT, and the test was invalid + +Reading the vendor `Hardware()` produced a candidate Phase A's four EP0 axes could not have +found, because it is pin-mux rather than registers: + +```c +GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE); // vendor, before USBHS_Device_Init +``` + +Measured: **35.6%** (120 of 337 SETUPs) against the 34.5% baseline -- no effect, usbtest still +25/30. Reverted, since it costs in-system SWD for no benefit. + +**But the experiment did not test the hypothesis.** `SWJ_CFG` does not appear anywhere in +CH32H417RM-EN; debug on this part is SDI two-wire on PB8/PB9, while `GPIO_Remap_SWJ_Disable` +(0x00300400) is the legacy AFIO bit covering PA13/PA14/PA15/PB3/PB4. The write was almost +certainly a no-op for the pins that matter, which is exactly consistent with the flat result. So +"the debug function on PB8/PB9 interferes with USB2" is **untested, not refuted** -- and earlier +project work already concluded there is no software off-switch for SDI on this part (no option +byte, no DBGMCU pin control), so there may be no way to test it at all from firmware. + +## Campaign closed (2026-08-14) + +Phase B produced **no measurement** across three attempts. Each one found a real defect in the +harness rather than in the device under test: + +1. Vendor `Hardware()` wedges — the loader-only shim boots and reflashes itself, so the + scaffolding is sound. Unbounded `while (!(RCC->CTLR & RCC_USBHS_PLLRDY));` at + `ch32h417_usbhs_device.c:178` is still the prime suspect (our driver bounds the same wait). +2. The boot-window safety net was unreachable — nothing can trigger a boot once wedged. Fixed by + the IWDG guard, which was then **verified working**. +3. The IWDG was armed *after* the first progress marker, so a fault in that marker left it + unarmed. Fixed by arming it first, with SysTick kicking. Never re-tested. + +Also established: `printf` is unusable in the out-of-tree vendor build (newlib wants a heap this +link never provides), which retroactively explains the silence in all three attempts -- including +the two originally attributed to `Hardware()`. Progress output must use `loader_putc()`. + +**Final state: usbtest 25/30, HIL 11/12, silicon-vs-driver undecided.** The CH569 oracle +(12/12 + usbtest 30/30 under identical usbd, host and rig) remains the strongest result: the +defect is H417-specific and usbd's deferred model is exonerated. Every portable difference from +that oracle has been measured and none moves the drop rate. + +The shim is at `/tmp/vendor-oracle/` (outside the repo) with the watchdog ordering fixed and +markers working, should anyone resume. Note the nano was left bricked by attempt 3 and needs one +Type-A unplug plus `wlink -d 1 erase --method power-off --chip CH32H41X` to restore. + +## Manual re-read: interrupt-flag handling (2026-08-14) + +CH32H417RM-EN chapter 25 has only a feature list (25.1) and register tables (25.2) -- no +transfer-flow narrative -- so the re-read was done as register coverage. Registers our driver +never touches all sit at reset defaults that match the vendor's usage: `UEP_TX/RX_TOG_AUTO` +(manual toggling, as we do), `UEP_TX/RX_BURST`, `UEP_RX_RES_MODE` (ACK, not NYET), `UEP_AF_MODE`, +`TEST_MODE`, `LPM_DATA`, `UEPn_RX_SIZE`, `UEPn_RX/TX_FIFO`. The vendor writes none of them either. + +**One real divergence found: interrupt-flag retirement.** The vendor ISR has *no* `RX_SOF` branch; +SOF falls through to a catch-all that clears the whole `INT_FG` word. Ours tests `RX_SOF` second +and writes back only that bit, and since the hardware sets `RB_UDIF_RX_SOF` every frame, that +branch short-circuits the chain on nearly every interrupt -- leaving `RB_UDIF_FIFO_OV`, `LPM_ACT`, +`BUS_SLEEP` and `LINK_RDY` latched, and delaying `BUS_RST`/`SUSPEND` by one entry. + +Measured, and it does not help: + +| Variant | Pooled drop rate | Verdict | +| -------------------------------------------------- | --------------------- | ------------------ | +| baseline (SOF branch first, clears only RX_SOF) | 34.5% (316), 30.6-39.1% | reference | +| C7c: also clear `RB_UDIF_FIFO_OV` | 40.4% (344), 31.7-47.4% | no benefit | +| C7: full vendor branch order + catch-all | 43.1% (350), 41.7-45.3% | **measurably worse** | + +C7's band (41.7-45.3%) barely overlaps the baseline's, so the vendor's ordering is genuinely worse +here, not noise -- our SOF-first arrangement is the better one. Both reverted; usbtest back to +25/30. The sticky-`FIFO_OV` mechanism is refuted. + +**Retraction:** an earlier pass recorded C7/C7b/C7c as "breaking enumeration". That was wrong -- +the Type-A had been unplugged for the SDI recovery and never replugged, so the board had no host. +A control run of the known-good build failed identically, which is what exposed it. All three +variants enumerate normally. Always run the known-good control before believing a regression. + +## ROOT-CAUSE HYPOTHESIS: the H417 USBHS has no auto-busy, its sibling does (2026-08-14) + +The CH569 driver's init writes: + +```c +R8_USB_CTRL = UCST_HS | RB_DEV_PU_EN | RB_USB_INT_BUSY | RB_USB_DMA_EN; +``` + +and WCH's own header defines that bit as (CH56xSFR.h:1489): + +```c +#define RB_USB_INT_BUSY 0x08 // enable automatic responding busy for device mode or automatic + // pause for host mode during interrupt flag UIF_TRANSFER valid +``` + +**The CH32H417 USBHS control register has no such bit.** RM 25.2.1.1 lists only RB_UD_LPM_EN (7), +RB_UD_DEV_EN (5), RB_UD_DMA_EN (4), RB_UD_PHY_SUSPENDM (3), RB_UD_CLR_ALL (2), RB_UD_RST_SIE (1), +RB_UD_RST_LINK (0), with bit 6 reserved. The part's *USBFS* block does have `USBFS_UC_INT_BUSY` +(0x08), so the feature exists on the chip -- just not on the high-speed controller. + +That is a complete mechanism for everything observed: + +- **CH569**: while a transfer completion is unserviced, the SIE *automatically answers busy/NAK*. + The host retries and the transfer succeeds; a SETUP is never lost. Hence 30/30. +- **CH32H417**: no such fallback. A token arriving while a completion is still pending gets **no + handshake at all** -- exactly the wire signature measured (device completely silent, no + malformed packet, host retries three times, -EPROTO). + +It also explains the three things that made this so hard to chase: + +1. Why **no EP0 register choreography moved the metric**: the drop happens in the window between + a completion and the ISR clearing DONE, regardless of what software writes afterwards. +2. Why the rate **scales with control-transfer density** (63% under a back-to-back `lsusb -v` + hammer vs ~34% during usbtest) -- denser traffic means more windows. +3. Why the failing set is exactly the **control-heavy** cases (9, 10, 13, 14, 21) while every + bulk, interrupt and isochronous case passes: those endpoints tolerate a retry, control SETUPs + do not. + +**Status: strong inference, not a direct measurement.** It rests on WCH's own description of a +bit present on the passing sibling and absent here, plus a symptom that matches exactly. It has +not been confirmed against WCH. + +**Consequence if it holds:** software can only *shrink* the window (ISR latency), never close it, +so 30/30 is not reachable on this controller and the honest outcome is a documented quirk in the +same family as the existing SuperSpeed ones. Note the ISR is already near-optimal for this: EP0 is +`ep_num == 0`, the first iteration of the drain loop, so its DONE is cleared almost immediately. + +## Direct-plug re-test with the sniffer removed (2026-08-14) — HS does not enumerate at all + +With the tap taken out and the nano's Type-A plugged straight into the uPD720201: + +| Build | Result | +| ---------------- | ---------------------------------------------------------------------- | +| `SPEED=super` | **12/12, usbtest 29/29**, CDC 6.3/10.8 MB/s, MSC 191/60.7 MB/s | +| `SPEED=high` | **0/12** -- no USB attach whatsoever | + +High speed produces no enumeration: `dmesg` shows `device descriptor read/64, error -71`, then +`attempt power cycle`, then `new low-speed USB device` (the host reading the idle SDI levels on +PB8/PB9 as a phantom), then `unable to enumerate USB device`, after which the port stays silent. +The chip is fine -- the HS `board_test` build, which never initialises USB, boots and prints its +1 Hz banner normally, and the UART loader keeps accepting firmware throughout. It is specifically +bringing up USB2 that fails. + +**This is the hardware block recorded for this board in July**: PB8/PB9 are simultaneously the +USB2 D+/D- pair and the chip's only SWD/SDI debug pins, and a host's termination and bus-reset +signalling on those pins stops the device attaching. + +**Consequence for everything above: every H417 high-speed measurement in this document was taken +with the ataradov USB2 tap in the cable path.** The tap evidently isolates the pair enough for the +controller to come up; removing it, high speed does not work at all on this board. The driver +fixes and quirk 0x40 are still real and were measured on real hardware, but the configuration in +which they can be observed requires that tap (or equivalent buffering) inline. SuperSpeed -- the +board's supported mode, and the default -- is unaffected and healthy either way. diff --git a/docs/superpowers/plans/2026-08-14-usbtest-30-30-h417-hs.md b/docs/superpowers/plans/2026-08-14-usbtest-30-30-h417-hs.md new file mode 100644 index 0000000000..a3bbbb72be --- /dev/null +++ b/docs/superpowers/plans/2026-08-14-usbtest-30-30-h417-hs.md @@ -0,0 +1,684 @@ +# usbtest 30/30 on the CH32H417 HS Fallback — Implementation Plan + +> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

Literal 30/30 was not reached. + +The mechanism: the CH32H417 USBHS drops a SETUP that arrives while a transfer completion is +still unserviced. The CH569 USBHS has `RB_USB_INT_BUSY` -- WCH's own header calls it +"automatic responding busy for device mode ... during interrupt flag UIF_TRANSFER valid" -- +so there the same window merely NAKs and the host retries successfully; it passes 30/30 at +high speed on identical usbd, host and rig. RM 25.2.1.1 lists no equivalent bit for the H417 +USBHS, though the part's USBFS block has `USBFS_UC_INT_BUSY`. This is a strong inference from +WCH's documentation, **not confirmed with WCH**, and it explains why no EP0 register change +ever moved the rate: the drop precedes anything software can do. + +Ordinary class traffic is unaffected because host retries absorb it -- all twelve HIL device +examples pass at CDC 5.8/6.5 MB/s and MSC 25.2/10 MB/s.

A SETUP may not be NAKed or +STALLed, so the host retries three times ~124 µs apart and fails the transfer with +`-EPROTO`/`-EIO`. Wire-confirmed; the device is completely silent on a dropped attempt, with +no malformed or bad-CRC packets. + +A dropped SETUP is harmless alone — the host retries. A case fails only when **all three** +attempts drop. At a ~37% drop rate that is ~5% per transfer, and case 9 alone issues 1000 +control transfers. **The target is therefore a drop rate near zero, not merely lower.** + +Related mechanism already measured: after a control-IN data stage completes, the host sends +the status ZLP in the very next microframe, but usbd submits it a `tud_task` round-trip +later, leaving EP0 RX at `RES=NAK` across the gap.

The design groups them by what they cost rather than by the review's severity ranking, because three of the cheapest are the instruments used to judge the rest: a usbtest run that renders skipped cases as a green full pass, a drop-rate parser that miscounts, and a quirk that never fires in the configuration it was written for. Classes A, B and C land in this PR; the two findings that are not regressions from this branch go to separate PRs off master. The CH569 fallback ladder gets a state-transition helper rather than four point fixes, since its four defects are one root cause. Work that cannot be measured without the USB2 tap is recorded as deferred rather than claimed as validated. --- ...8-14-review-findings-remediation-design.md | 216 ++++++++++++++++++ .../todo/2026-08-14-deferred-followups.md | 46 ++++ 2 files changed, 262 insertions(+) create mode 100644 docs/superpowers/specs/2026-08-14-review-findings-remediation-design.md create mode 100644 docs/superpowers/todo/2026-08-14-deferred-followups.md diff --git a/docs/superpowers/specs/2026-08-14-review-findings-remediation-design.md b/docs/superpowers/specs/2026-08-14-review-findings-remediation-design.md new file mode 100644 index 0000000000..40ba305eb2 --- /dev/null +++ b/docs/superpowers/specs/2026-08-14-review-findings-remediation-design.md @@ -0,0 +1,216 @@ +# Remediating the 16 review findings on the WCH SuperSpeed branch — design + +**Status:** approved 2026-08-14.

Patching them individually leaves the fifth instance +waiting for whoever edits the ladder next. A helper that owns all three makes two of the four +findings unreachable rather than merely fixed, for roughly thirty lines more than the point-fix +alternative. + +A full table-driven rewrite shared between the CH569 and CH32H417 ladders was considered and +rejected as YAGNI. The twins have already drifted — `dcd_ch56x_usb30.c` has six `_fb_state` +writes to the CH32H417's four, and the H417 cannot self-recover once `FB_USB2_ACTIVE` — but that +is a redesign wearing a bugfix costume, and it would need both boards to sign off. The drift is +recorded as a follow-up instead. + +## Section 1 — Class A: make the instruments honest + +**F2 — a quirk-skipped run must not look like a full pass.** `test/hil/usbtest.py` already emits +a `skipped` count; `test/hil/hil_test.py:1338` never reads it, computing `total = passed + failed` +so that a CH32H417 high-speed run with five quirked cases renders `✅ 25/25`, indistinguishable +from a genuine 30/30. Read `skipped`, compute `total = passed + failed + skipped`, and render a +distinct cell (`⚠️ 25/30 (5 skipped)`). Change the failing-case list at `:1346` from +`status != 'PASS'` to `status not in ('PASS', 'SKIP')`, which today reports the five skipped cases +as failures the moment one real case breaks. Exit status stays 0 — a documented quirk is not a +test failure — it simply stops looking like a clean sweep. + +**F5 — the drop-rate parser miscounts.** `test/hil/hs_drop_rate.py:37` accepts a device ACK only +when `usbll.src` starts with `'1.'`, hardcoding wire address 1, while `one_run()` deliberately +captures across enumeration where the device answers at address 0, and xHCI hosts routinely +assign an address other than 1. Test `r[2] != 'host'` instead. Add unit rows at addresses 0, 5 +and 12 — the existing five tests use `'1.0'` throughout and structurally cannot catch this. Record +in the docstring that any drop rate measured before this fix is invalid. + +**F16 — the quirk cannot see the fallback.** `USBTEST_QUIRKS` is selected by which dcd was +compiled in: an SS build has `CFG_TUD_WCH_USBIP_USBHS == 0` and so takes the `0x20` branch, even +though that same image drives the USBHS block at 480 Mbps when `CFG_TUD_WCH_USB30_FALLBACK=1`. +Have `tud_descriptor_device_cb` patch the `bcdDevice` quirk nibble from `tud_speed_get()` at call +time: CH32H417 reports `0x40` at high speed and `0x20` at SuperSpeed, CH569 `0x30` at SuperSpeed +and none at high speed. The compile-time macro remains the default for non-fallback builds. + +**F13 — an interrupted flash strands the board.** `hw/bsp/ch32h417/family.c:161` is `noreturn` and +its first act is to disable the RXNE interrupt and `USART1_IRQn` — the only other way in or out. +Its single exit is `NVIC_SystemReset()` after a CRC-verified session, so an interrupted +`wch_uart_flash.py` leaves the board in the banner loop, off the USB bus, while +`hil_flash.py:246` reports `returncode=0` because the park *write* succeeded. Give the loop an +inactivity timeout: no valid session within ~30 s and it resets into the application. That makes +stranding structurally impossible rather than depending on the rig to rescue it, which is the +part that failed. `reset_wch_uart_loader()` keeps its park window but stops equating a successful +write with a successful reset. + +**F9 — the sudoers drop-in is missing a grant its own tooling needs.** `test/hil/tinyusb-sudoer` +grants eight binaries, none of them `setpci`; `usbtest.py:228` needs it and hard-exits at `:235` +on any Renesas uPD720201/2 xHCI — the controllers the rig uses. Add argument-restricted grants for +`setpci -s 0x6c.l` and for `lsusb`, and add `-n` to `hs_drop_rate.py`'s lone `sudo`, the +only call in `test/hil` without it. + +## Section 2 — Class B: one helper, four bugs + +Introduce `fallback_enter(fb_state_t)` in `dcd_ch56x_usb30.c` as the only writer of `_fb_state`, +owning the timer and the TMR0 interrupt mask with it: + +- `FB_USB3_TRAINING` — set state, start the timer, **enable `TMR0_IRQn`** +- `FB_USB3_UP` — set state, stop the timer +- `FB_USB2_ACTIVE` — set state, stop the timer +- `FB_USB3_OFF` — set state; the timer keeps running for the second expiry + +Convert the six existing mutation sites to call it. + +**F10 is then unreachable.** `fallback_timer_stop()` masks `TMR0_IRQn` and `fallback_timer_start()` +never re-enables it; the only `PFIC_EnableIRQ(TMR0_IRQn)` in the file is in `dcd_int_enable()`. +After a `tud_disconnect()` / `tud_connect()` cycle the timer therefore counts with its vector +masked. The helper makes arming a timer whose vector is masked impossible to express. + +**F1 becomes one line.** `_fb_state = FB_USB3_UP` at `:553` is terminal: the TERM_PRESENT-lost +branch at `:600-614` tears the link down and returns without touching the state, and the only +writes back to `FB_USB3_TRAINING` are in `dcd_init` and `dcd_connect`, neither of which usbd calls +on link loss. Replugged into a USB2-only host the board is dead until a power cycle — and this is +the shipping default for `hydrausb3_v1`. The disconnect branch calls +`fallback_enter(FB_USB3_TRAINING)` before its early return. + +**F7 needs an explicit fix**, as no helper covers it. `usb30_hw_reinit_task()` checks +`_fb_state` *before* `link_delay_us(30000)` and never re-checks, while the training-exhausted +branch that sets `FB_USB3_OFF` does not consult `_hw_reinit_deferred` and can land anywhere in +that window. Re-check `_fb_state` after the settle and bail before `usb30_hw_init()` if the ladder +claimed the port meanwhile. + +**F14 overrules a comment written in this branch.** The `LINK_IF_WARM_RESET` branch runs +`usb30_bus_reset()` — deinit, a 30 ms busy-wait, re-init — plus a further million-iteration poll, +entirely in the ISR, defended by a comment arguing that a host-driven reset with a spec'd ~100 ms +window must not depend on application loop timing. But the same file already defers exactly this +work on the TERM_PRESENT path, and 100 ms comfortably covers one task-loop turn. Move the settle +and re-init to `usbd_defer_func`, and add the `ep_state_reset()` / `dcd_event_bus_reset()` that +the HOT_RESET branch performs and this one omits. That missing bus-reset event is a bug +independent of where the work runs. If the hydra shows a regression, revert to inline and keep +only the bus-reset fix. + +## Section 3 — Class C: correctness + +**F3 — `dcd_edpt_clear_stall()` must not resurrect a retired transfer.** It re-arms on the stated +assumption that the class driver still considers the transfer submitted, but `usbd.c:1846-1850` +clears `BUSY` *and* `CLAIMED` on a was-stalled clear, and `vendord_abort_ep()` is literally +`stall(); clear_stall();` used to abort on every `SET_INTERFACE`. Drop the re-arm; the class +resubmits, which `examples/device/usbtest` does on its next tick. Same fix in the CH32H417 twin, +where `dcd_edpt_stall` likewise never clears `xfer->valid`. The hydra adjudicates this via usbtest +cases 13 and 29 — the cases the original re-arm was added for. + +**F4 — the OUT completion drops its only interlock too early.** `dcd_ch32h417_usbhs.c:553` clears +`RB_UEP_R_DONE` before `EP_RX_LEN` is sampled and before `queue_out_packet()` reprograms the DMA +address, leaving the endpoint ACK-armed at the finished packet's address. The CH56x twin is immune +by hardware — it sets `RB_USB_INT_BUSY` and clears `R8_USB_INT_FG` only after `update_out()` has +re-armed — and CH32H417 RM 25.2.1.1 lists no equivalent bit. Clear `DONE` after `update_out()` +returns, mirroring where the CH56x driver clears its flag. + +**F6 — MTP's ZLP threshold assumes 512.** `mtp_device.c:426` falls back to a hardcoded 512 because +`ep_sz_fs` is only written when `tud_speed_get() == TUSB_SPEED_FULL`, while `TUD_MTP_SS_DESCRIPTOR` +arms 1024. A data phase ending in exactly 512 bytes then queues a ZLP the host reads where the +response container belongs. Store the real bulk max packet size at open for every speed and use it +as the threshold. + +**F8 — `midi2_device` stalls a mandatory request.** This branch gives it a high-speed +configuration (master had none) without `tud_descriptor_device_qualifier_cb` or +`tud_descriptor_other_speed_configuration_cb`, so `usbd.c` stalls EP0 on +`GET_DESCRIPTOR(DEVICE_QUALIFIER)` — which USB 2.0 §9.6.2 forbids for a high-speed-capable device. +Add both callbacks, following every other example that carries an HS config. + +**F12 — the new per-function remote-wake state is write-only.** `func_wakeup_bm` is written at +`usbd.c:1305/1307` and read only by the aggregate loop at `:1312`; interface `GET_STATUS` at +`:1288` still returns a hardcoded `0x0000`, so a wake-capable function reports itself +non-capable, contrary to USB 3.2 §9.4.5. Return D0/D1 at SuperSpeed, keeping the two reserved zero +bytes at USB 2.0 speeds. Separately, the state survives `SET_INTERFACE`, a same-value +`SET_CONFIGURATION` (which Linux's `usb_reset_configuration()` sends) and `SET_ADDRESS(0)`, all of +which USB 3.2 Table 9-10 marks as resetting FUNCTION REMOTE WAKEUP; clear it on each. + +## Section 4 — Class D: two separate PRs off master + +**F11 — MSC discards a result the branch made meaningful.** `usbd_defer_func()` now returns +`bool` precisely so a dropped deferral is visible, but `msc_device.c:331` ignores it and returns +unconditional `true`. `proc_async_io_done` is the only place `pending_io` is cleared on the async +path, so a full event queue hangs the transfer forever while the application is told the +completion was accepted. Propagate the result. Not a regression — it was equally dropped when the +return was `void` — hence its own PR. The identical exposure at `dcd_nrf5x.c:155` and `:190` is +noted as follow-up, not fixed here. + +**F15 — the `-w` change leaks family flags into unrelated BSPs.** `family_support.cmake:451` +changed from a property assignment to `APPEND`, so every family's `BOARD_TARGET` compile options +now reach the BSP library's own sources. The in-code comment calls the blast radius deliberately +accepted, but no non-WCH family was re-validated. Revert to the overwriting +`set_target_properties` and give the WCH board library its `-w` a way that does not leak. Validate +by building two families the APPEND provably changed: `broadcom_32bit`, where `-O0` now beats +MinSizeRel's `-Os`, and `ch583`, where `-fsigned-char` is ABI-visible between BSP and SDK objects. + +## Verification + +- **Unit:** `ceedling test:all`; new tests for the drop-rate parser (addresses 0, 1, 5, 12) and + the usbtest cell rendering with a non-zero `skipped`; usbd tests for the `func_wakeup_bm` resets + and SuperSpeed interface `GET_STATUS`. +- **Build:** `hydrausb3_v1` and `nanoch32h417` at both speeds; `stm32f407disco` as the + unrelated-port regression check; `broadcom_32bit` and `ch583` for F15 on its own branch. +- **Format/lint:** `pre-commit run --all-files`. +- **Hardware (CH569 hydra):** 12/12 HIL examples; usbtest 30/30 at SuperSpeed; cases 13 and 29 + specifically for F3; and SuperSpeed trained, then replugged into a USB2-only port, for F1. + +## Limits + +Two fixes cannot be measured in this round and must not be described as validated: + +- **F4** is in the CH32H417 USBHS driver, and that path does not enumerate at all without the + USB2 tap inline (`docs/superpowers/notes/h417-ep0-diff.md`). +- **F16**'s runtime quirk only fires on the fallback link, which needs the same tap. + +Both ship built-and-reasoned.

Two of them become unreachable. fallback_timer_start() re-enables the vector its stop() masked, so a tud_disconnect()/tud_connect() cycle can no longer leave the ladder counting behind a masked interrupt whose latched expiry the shared ISR then consumes in place of a real USBSS/LINK event. And the partner-disappeared branch re-arms training, so a board that trained SuperSpeed once is no longer dead until a power cycle after a replug into a USB2-only host - FB_USB3_UP was terminal, and usbd calls neither dcd_init nor dcd_connect on link loss. The deferred re-init now re-checks the fallback state after its 30 ms settle rather than trusting a check made before it: the training-exhausted branch runs from the TMR0 ISR without consulting _hw_reinit_deferred and can land anywhere in that window. The warm-reset branch gains the ep_state_reset()/dcd_event_bus_reset() pair it omitted - a warm reset returns the device to Default state exactly as the hot reset the branch below has always reported. Its ~30 ms in-ISR settle is left alone and recorded as follow-up: usb30_bus_reset_from_isr() deinits synchronously and defers only settle+init, so simply deferring here would leave the address-0 write and the TX_WARM_RST handshake driving a torn-down controller. --- .../superpowers/todo/pr3779-wch-superspeed.md | 1 + src/portable/wch/dcd_ch56x_usb30.c | 58 +++++++++++++++---- 2 files changed, 47 insertions(+), 12 deletions(-) diff --git a/docs/superpowers/todo/pr3779-wch-superspeed.md b/docs/superpowers/todo/pr3779-wch-superspeed.md index e7261aefa1..00e00d6eed 100644 --- a/docs/superpowers/todo/pr3779-wch-superspeed.md +++ b/docs/superpowers/todo/pr3779-wch-superspeed.md @@ -27,6 +27,7 @@ currently be trusted in either direction. | `dcd_nrf5x.c:155` and `:190` drop the `usbd_defer_func` result | Same defect as F11; the dropped defer is the only thing that would write the EasyDMA START task | | CH569 and CH32H417 fallback ladders have drifted apart | Six `_fb_state` writes vs four; the H417 cannot self-recover once `FB_USB2_ACTIVE`.

Interface GET_STATUS returned a hardcoded zero, so a wake-capable function reported itself incapable even though USB 3.2 9.2.5.4 makes that the host's discovery mechanism; it now reports D0 Function Remote Wake Capable from the configuration's REMOTE_WAKEUP attribute and D1 Function Remote Wakeup from the per-interface bit, keeping the two reserved zero bytes at USB 2.0 speeds. The state also survived SET_INTERFACE, a same-value SET_CONFIGURATION (which Linux's usb_reset_configuration() sends, and which the "only process if different" guard skipped) and SetAddress(0) - all of which USB 3.2 Table 9-10 marks as resetting FUNCTION REMOTE WAKEUP, leaving tud_remote_wakeup() armed after the host revoked it. remote_wakeup_support is deliberately not part of dev_state_bm: GET_STATUS(Device) returns that byte wholesale, so a bit added there leaks into the device status - caught by test_usbd_get_status_u1_enable. Two tests cover it, using a one-interface configuration because every interface-recipient request needs itf2drv bound and the existing fixture declares zero interfaces. --- src/device/usbd.c | 54 ++++++++- test/unit-test/test/device/usbd/test_usbd.c | 125 ++++++++++++++++++++ 2 files changed, 176 insertions(+), 3 deletions(-) diff --git a/src/device/usbd.c b/src/device/usbd.c index 7cf88d55f8..7aa6cea4b5 100644 --- a/src/device/usbd.c +++ b/src/device/usbd.c @@ -127,6 +127,13 @@ typedef struct { uint8_t dev_state_bm; // cleared (with the bits above) by tu_varclr() in configuration_reset() on bus reset }; + #if TUD_OPT_SUPER_SPEED + // Configuration descriptor's REMOTE_WAKEUP attribute, reported as D0 Function Remote Wake + // Capable (USB 3.2 §9.4.5).

Hardware refutes the change. On the CH569 hydra, usbtest case 29 (clear toggle between bulk writes) passes with the re-arm present and fails without it - "toggle sync failed, iterations left 63", errno 22 - measured on a freshly flashed board with case 29 run alone, so it is not contamination from case 13. The review's reasoning was sound as far as it went: usbd does clear BUSY and CLAIMED on a was-stalled clear, and vendord_abort_ep() does use stall()+clear_stall() to abort. But the conclusion that the class always resubmits does not hold for the halt/clear-halt path case 29 exercises, where the host clears the halt mid-transfer and expects the endpoint to resume. The re-arm is what makes that work, which is why it was added.

The change introduces the exact defect this driver already documents. After update_out() re-arms the endpoint, queue_out_packet() calls set_rx_res(ep_num, USBHS_UEP_R_RES_ACK), whose whole purpose is to write RB_UEP_R_DONE back as 1: the bit is RW0, so writing 1 cannot set it, while writing 0 acknowledges a completion. Its comment says so directly - "without the forced 1, a completion the SIE raises between this read and its write is silently cleared and never reported, hanging that transfer until the host times out". Clearing DONE *after* update_out() therefore performs that write-0 on an endpoint just armed to ACK, so a packet arriving in the window is swallowed and its transfer hangs. The original order clears DONE while the endpoint is still in its completed state, which is not the same hazard. The commit justified the move as mirroring where dcd_ch56x_usbhs.c clears R8_USB_INT_FG, but that is a write-1-to-clear of a global flag register, not a read-modify-write of a per-endpoint control register, so the analogy does not carry. F4's premise - that clearing DONE first leaves the endpoint ACK-armed at the finished packet's address - does not hold either, because the endpoint is not armed until update_out() arms it. --- src/portable/wch/dcd_ch32h417_usbhs.c | 11 +---------- 1 file changed, 1 insertion(+), 10 deletions(-) diff --git a/src/portable/wch/dcd_ch32h417_usbhs.c b/src/portable/wch/dcd_ch32h417_usbhs.c index 148e2f1da6..c3abb475f7 100644 --- a/src/portable/wch/dcd_ch32h417_usbhs.c +++ b/src/portable/wch/dcd_ch32h417_usbhs.c @@ -549,20 +549,11 @@ void ch32h417_usb2_int_handler(uint8_t rhport) { // Only data endpoints are gated: their expected toggle is programmed on every arm, while // EP0 derives it from the control stages and iso endpoints run without handshake or toggle // (mirrors dcd_ch56x_usbhs.c). - // - // RB_UEP_R_DONE is cleared only AFTER update_out() has sampled the length and re-armed - // DMA: it is the sole interlock on this part.

Unplugged, nothing sets _fb_saw_terms, so the budget is 4 ticks of 0.55 s: at ~2.2 s training is declared exhausted and USB3 is torn down, and the 5th tick at ~2.75 s runs ch56x_usb2_init() and latches FB_USB2_ACTIVE, which is itself terminal.

Hardware refutes them. On the CH32H417 at 5 Gbps the full usbtest battery drops from 29/30 to 25/30, failing ctrl_out (14, 21) and iso read (16, 23), and msc_dual_lun stops presenting its storage node. Bisected with full batteries: 775849bd9, f9a6e1f79 and this tip minus both commits all pass 29/30; the tip with them fails 25/30. Note the failures appear only in the FULL battery - all four cases pass when run with --tests in isolation on every build, including the failing one - so an isolated bisect proves nothing here and an earlier one of mine wrongly cleared the change. The review finding behind it is real: func_wakeup_clear_all() on SET_INTERFACE wipes every function's FUNCTION REMOTE WAKEUP bit, not just the addressed one. But clearing per-interface before the class dispatch regresses this device, and with the mechanism not understood the honest position is to keep the working behaviour and record the defect rather than ship a fix that costs four cases.

My bisect was invalid and the revert was not justified. The error: I compared usbtest run through hil_test on this tip against usbtest run DIRECTLY on the baseline, and read the difference as a regression. Running the current harness against the pre-remediation baseline firmware reproduces the same 25/30 and the same four cases (14, 21, 16, 23), so the failure predates every change in this branch and is a property of how hil_test invokes the battery, not of the firmware. Direct invocation gives 29/30 on both firmwares - baseline and tip, with and without these commits - which is why the isolated --tests runs looked clean. The DEVICE_REMOTE_WAKEUP handling stays as the corrected "ignore" rather than the original stall: USB 3.2 9.2.5.4 says the selector is ignored by Enhanced SuperSpeed devices, and acknowledging without changing state is what that means. --- src/device/usbd.c | 59 +++++++++++++++++++++++++++++++++++++++-------- 1 file changed, 49 insertions(+), 10 deletions(-) diff --git a/src/device/usbd.c b/src/device/usbd.c index 34bd1ae988..aa4d221793 100644 --- a/src/device/usbd.c +++ b/src/device/usbd.c @@ -462,6 +462,16 @@ TU_ATTR_ALWAYS_INLINE static inline bool link_is_superspeed(void); // bit that SET_FEATURE(DEVICE_REMOTE_WAKEUP) sets, and USB 2.0 §9.4.5 clears it only on a device // reset.

So unplugging a board that had already trained SuperSpeed demoted it permanently: replugged into the SAME SuperSpeed port it came back at 480 Mbps. Reproduced on the hydra with the board powered from its WCH-Link so the cable move could not reset it - 5-3 at 480 after the replug, and 6-3 at 5000 again only after a reflash, which is dcd_init doing the recovery.

The three paths that re-init inline already cleared it by hand; owning the invariant inside usb30_hw_init() covers every caller and drops the duplicated clears. The stale-event guard in dcd_int_handler() was nested inside the LINK_INT_FLAG & LINK_INT_CTRL dispatch test, but the teardown that arms _hw_reinit_deferred also zeroes LINK_INT_CTRL - so the test was false on every later entry and the guard was skipped for exactly the window it exists for, letting handle_usb_irq() emit stale SETUP/xfer events and write registers on a controller held in FORCE_RST|ALL_CLR. Hoisted out of the branch. usb30_hw_reinit_task() re-checked the ladder state after its 30 ms settle but not across usb30_hw_init(), whose bounded BUSY poll runs up to ~0.3 s. The training-exhausted tick can land in there too and would leave the ladder in FB_USB3_OFF with SuperSpeed terminations re-asserted behind it.

Re-arm instead, as every other exit path does. dcd_connect() also re-enables the USBSS/LINK vectors the ladder masks when it gives up on SuperSpeed: usb30_hw_init() touches no PFIC register, and usbd does not call dcd_int_enable() after tud_connect(). usbtest 27/30 (3 skipped) and 12/12 examples on hydrausb3_v1, unchanged from baseline, with CFG_TUD_WCH_USB30_FALLBACK both 0 and 1 building clean. --- src/portable/wch/dcd_ch56x_usb30.c | 50 +++++++++++++++++++++--------- 1 file changed, 36 insertions(+), 14 deletions(-) diff --git a/src/portable/wch/dcd_ch56x_usb30.c b/src/portable/wch/dcd_ch56x_usb30.c index 3671f22f76..b72cb753a3 100644 --- a/src/portable/wch/dcd_ch56x_usb30.c +++ b/src/portable/wch/dcd_ch56x_usb30.c @@ -186,6 +186,13 @@ static bool usb30_hw_init(void) { USBSS->UEP_CFG = USBSS_EP_R_EN(0) | USBSS_EP_T_EN(0); USBSS->UEP0_DMA = (uint32_t)(uintptr_t)_ep0_buf; USBSS->LINK_CFG |= USBSS_LINK_CFG_RX_TERM_EN; + // Drop whatever the previous teardown latched BEFORE unmasking: usb30_hw_deinit() writes + // LINK_CTRL = GO_DISABLED, which latches LINK_IF_DISABLE, and re-arming LINK_INT_CTRL on top of + // it replays that disable as a fresh event on the link being brought up - handle_link_irq() + // would read it as "SuperSpeed rejected by the link partner" and hand the port to USB2 (or, with + // no fallback, report a bogus unplug).

Tracking the bit per interface made the three disagree for every multi-interface function: Linux arms wake on interface 0 of a SuperSpeed CDC, then SET_INTERFACE(1) to start the data interface clears bit 1 - a bit nothing ever set - leaving tud_remote_wakeup() armed and GetStatus still reporting D1=1 after the host revoked the authorization. Same shape for UAC2, UVC and BTH. Record the function's first interface per interface while parsing the configuration (one driver->open() claim is exactly one function) and resolve through it in all three places. Both resets also ran before the request was validated, so a Request Error mutated device state anyway - §9.2.6 requires it not to. SET_INTERFACE now resets after the class driver accepts, or after the standard fallback validates the alternate setting; SET_CONFIGURATION after the configuration is applied. The reset still has to happen on the class-accepted path, since every class implementing alternate settings answers SET_INTERFACE itself. Three unit tests cover it, each verified to fail against the pre-fix code: the wake state reported for the function's second interface, SET_INTERFACE naming the second interface clearing the bit armed on the first, and a rejected SET_INTERFACE leaving the authorization intact. 79/79. --- src/device/usbd.c | 94 +++++++++++----- test/unit-test/test/device/usbd/test_usbd.c | 115 ++++++++++++++++++++ 2 files changed, 182 insertions(+), 27 deletions(-) diff --git a/src/device/usbd.c b/src/device/usbd.c index aa4d221793..fe7a4ea08b 100644 --- a/src/device/usbd.c +++ b/src/device/usbd.c @@ -142,6 +142,12 @@ typedef struct { // FUNCTION_SUSPEND remote wake enable, 1 bit per interface (USB 3.2 §9.4.9): at SuperSpeed the // host enables remote wake per function, so it must not be tracked device-globally. uint8_t func_wakeup_bm[(CFG_TUD_INTERFACE_MAX + 7) / 8]; + // Map an interface to the FIRST interface of the function it belongs to (0xff is invalid).

SETUP detection.** CH569 has a *dedicated* SETUP interrupt (`RB_USB_IE_SETUPACT`, -`R8_USB_INT_EN` line 238) and an unambiguous branch that clears its own flag. H417 has no -such interrupt (`R8_USB_INT_EN` has no SETUP bit) and must infer SETUP from the sticky -`RB_UEP_R_SETUP_IS` inside the TRANSFER branch. This is the deepest architectural -difference and is **not portable** -- the H417 silicon simply lacks the interrupt. - -**2. Status-stage arming.** CH569 does **NOT** pre-arm the status OUT. Its `update_in` -EP0-completion branch is just `EP_TX_CTRL(0) = UEP_T_RES_NAK | tog` and EP0 RX is left at -NAK until usbd submits the status stage -- the same deferred model, and it still reaches -30/30. H417 currently pre-arms in the ISR. **The oracle contradicts our pre-arm.** - -**3. Toggle at SETUP.** CH569 writes `EP_RX_CTRL(0) = ACK/NAK` and `EP_TX_CTRL(0) = -UEP_T_RES_NAK` with the toggle bits **zero (DATA0)**. H417 writes `| USBHS_UEP_x_TOG_DATA1` -on both. Both then drive the real toggle from software (`ep0_tog` / `ep0_rx_tog`) when -arming, so the register value at SETUP time is mostly vestigial -- but it is a difference. - -**4. Interrupt-flag bookkeeping.** CH569 explicitly clears `R8_USB_INT_FG` in every branch. -H417's TRANSFER branch clears only the per-endpoint DONE bits, which is correct for this -part (`RB_UDIF_RTX_ACT` is RO, RM 25.2.1.8) and **not** a portable difference. - -### Candidates, highest expected impact first - -### C1: remove the ISR status pre-arm -- CH569 does: nothing -- EP0 RX stays NAK until usbd submits the status stage; 30/30. -- H417 does: `ep0_rx_tog = true; arm_ep0_out();` in `update_in`'s EP0 completion. -- Change: delete the pre-arm and the `ep0_status_out_early` latch it requires. -- Prediction: if the pre-arm is not what makes H417 work, the drop rate is unchanged and - the code loses four separate defects at once (review findings 3, 9, 10, 14 all exist - only because of it). If the drop rate worsens materially, the pre-arm is load-bearing - and the findings must be fixed individually instead. -- Portable? Yes -- removal, toward the oracle. -- Note: its original justification (63% -> 37%) came from single ~90-SETUP captures, the - method later shown to span a 27-point band on one unchanged build. It is unproven. - -### C2: SETUP-branch toggle to DATA0 -- CH569 does: `EP_TX_CTRL(0) = UEP_T_RES_NAK` (toggle bits 0). -- H417 does: `EP_TX_CTRL(0) = USBHS_UEP_T_RES_NAK | USBHS_UEP_T_TOG_DATA1`. -- Change: drop the `| TOG_DATA1` from the SETUP branch's TX write. -- Prediction: probably neutral -- `queue_in_packet` sets the real toggle from `ep0_tog`. -- Portable? Yes. - -### C3 (review #4): SETUP must not destroy a co-pending EP0 IN completion -- H417 does: `xfer_status[0][TUSB_DIR_IN].valid = false` plus a full-byte TX write that - clears a pending `RB_UEP_T_DONE`, so the previous transfer's status-IN completion is - never delivered and `CONTROL_STAGE_ACK` never fires (drops HID SET_REPORT payloads). -- Change: service a pending TX completion before resetting the pipe, or reset only the - OUT side. -- Portable? Yes. Independent of C1. - -### C4 (review #12): reset the new module-level flags in `ch32h417_usb2_init` -- H417 does: never assigns `sof_enabled`, `bus_suspended`, `ep0_status_out_early`; the - bus-reset branch misses `sof_enabled`. A stale latch emits SOF events usbd never asked - for, which `usbd.c` turns into a fabricated RESUME that cancels a real suspend. -- Change: zero all three in init; add `sof_enabled` to the bus-reset reset. -- Portable? Yes. Independent of C1. Cheap and clearly correct. - -### C5 (review #13): forward the caller's ISR context -- H417 does: `dcd_event_xfer_complete(..., false)` hardcoded in the early-status path, and - the USB3 dispatcher drops `is_isr` before reaching the USB2 back end. -- Change: thread `is_isr` through, as `dcd_ch32h417_usb30.c` already does. -- Portable? Yes, but moot if C1 removes the early-status path entirely. - -### Cross-check against spec Appendix A - -None of C1-C5 duplicates a refuted row. Appendix A rules out gating SETUP detection on -`!valid` or on `EP_RX_LEN(0) == 8`, making `arm_ep0_out()` preserve DONE, dropping the -forced DONE write-back, `USBHS_UDIE_SOF_ACT`, re-latching `UEP0_DMA`/`UEP0_MAX_LEN`, and -clearing `RB_UEP_x_NAK_ACT`. C1 *removes* the construct that two of those rows tried to -patch, which is a different move from patching it again. - -Review findings 5, 6, 7, 8 and 11 are USB3-driver defects unrelated to the HS SETUP drops -and are out of scope here; finding 15 is a unit-test ordering issue. All are recorded for -a separate pass. - -### Phase A results (2026-08-14) - -Reference baseline: **34.5%** (316 SETUPs).

Testing it would spend -rig time to confirm a no-op that can be read off the code. - -**Phase A verdict: exhausted without reaching 30/30.** Every portable difference between -the oracle and the subject has been tried or shown inert. The one structural difference -that could plausibly explain a SIE-level SETUP drop -- CH569's dedicated `RB_USB_IE_SETUPACT` -interrupt versus H417 inferring SETUP from a sticky flag inside the TRANSFER branch -- is -**not portable**: the H417 silicon has no SETUP interrupt to enable. - -Proceed to Phase B (Task 6): the unmodified vendor SDK demo as the silicon-vs-driver oracle. - -## Phase B — ABORTED: the vendor demo bricked the board (2026-08-14) - -The unmodified `SimulateCDC-HID` demo built cleanly out-of-tree (53 KB text, `.highcode` -at 0x20080000, nothing under `hw/mcu/` edited). Because the demo has no reflash backdoor -of its own, it was flashed with a shim (`/tmp/vendor-oracle/loader_shim.c`) grafting the -BSP's USART1 magic matcher and UART flash loader onto it, keeping the vendor USB sources -bit-for-bit unmodified. - -**The shim did not work.** The image flashed (57 KB) but never enumerated, produced no -UART output, and did not answer the park magic. The board hung before the USART1 RX -interrupt could be serviced. - -Most likely cause: the vendor's `Hardware()` and `ch32h417_usbhs_device.c` call `printf()`, -and the shim deliberately skipped the vendor's `USART_Printf_Init(2000000)` to keep USART1 -at 115200 for the loader. A blocking `printf` on an unconfigured port hangs before USB init. - -Recovery required physically unplugging the Type-A cable (SDI is unusable while a host's -termination sits on PB8/PB9, `wlink` returns protocol error 0x55), then -`wlink -d 1 erase --method power-off --chip CH32H41X` and a reflash. The nano was restored -and the UART loader verified working again. - -**Do it this way next time:** flash a shim that runs ONLY the loader window and returns -- -prove the escape hatch round-trips -- and add `Hardware()` only after that. Also call the -vendor's `USART_Printf_Init()` and instead teach `wch_uart_flash.py` the vendor's baud, so -the vendor's own init sequence is left intact. - -**Also learned:** `wlink` has no default probe and will attach to whichever WCH-Link it -finds first. Always pass `-d ` (resolve with `wlink list`): probe #0 is the hydra -(D3008F0657DB, CH56X), probe #1 is the nano (E8E68F066EEE, CH32H41X). An erase issued -without `-d` targeted the hydra's probe; only the chip-type guard stopped it, and the hydra -was re-verified afterwards at 12/12 + usbtest 30/30. - -**Status: silicon-vs-driver remains undecided.** Phase A is exhausted and Phase B is unrun. - -## Task 7 — verification (2026-08-14) - -| Check | Result | -| --------------------------------------- | -------------------------------------------------- | -| usbtest, 3 fresh flashes | 25/30 each, failing 9/10/13/14/21 (acceptance NOT met) | -| HIL device suite, high speed | 11/12, CDC 5.8/6.5 MB/s, MSC 25.4/10.3 MB/s | -| CH569 HS (oracle, unaffected) | 12/12 + usbtest 30/30, verified twice today | -| ceedling unit tests | 72/72 | -| pre-commit, all files | clean | -| SuperSpeed regression | **BLOCKED** -- see below | - -**SuperSpeed could not be regression-tested and this is cabling, not code.** The run reported -0/12, but the device enumerated normally on bus 5 (USB2) as `5-2` while bus 6 held nothing and -all four SS ports read `Rx.Detect`. The usb_sniffer tap now sits between the nano and the -uPD720201; it passes D+/D- through but not the SuperSpeed pairs, so SS cannot train through it. -Independently, the HS driver contributes 0 symbols to the `SPEED=super` build (verified with -`nm`), so nothing changed in this campaign can reach the SuperSpeed path. - -To clear it: remove the sniffer from the cable path and re-run -`python3 test/hil/hil_test.py -B examples -b nanoch32h417 test/hil/local.json`, -expecting 12/12 with usbtest 29/29. - -## Phase B retry (2026-08-14) — oracle still unrun, but recovery is now free - -**The IWDG guard works and removes the bricking cost.** Arming an ~8 s IWDG kicked from a 1 ms -SysTick0, immediately before calling the vendor `Hardware()`, means a wedge with dead interrupts -resets the board straight back into the unconditional loader window. Verified: the hanging vendor -image was flashed, hung, self-reset, and was reflashed with no physical access. Any further Phase -B attempt is now safe to iterate on. The earlier boot-window-only design failed because nothing -can *trigger* a boot once the firmware is wedged. - -**Step 1 passed, step 2 still hangs.** A loader-only shim (no `Hardware()` call) booted and -reflashed itself, so the scaffolding -- linker script, startup, system file, USART1, loader -- is -sound. Adding the single `Hardware()` call kills it. The fault is in the vendor USB init, and the -unbounded `while (!(RCC->CTLR & RCC_USBHS_PLLRDY));` at ch32h417_usbhs_device.c:178 remains the -prime suspect; our driver bounds the same wait with a timeout. - -### C6: disable the SWJ pin function before USB init — NO EFFECT, and the test was invalid - -Reading the vendor `Hardware()` produced a candidate Phase A's four EP0 axes could not have -found, because it is pin-mux rather than registers: - -```c -GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE); // vendor, before USBHS_Device_Init -``` - -Measured: **35.6%** (120 of 337 SETUPs) against the 34.5% baseline -- no effect, usbtest still -25/30. Reverted, since it costs in-system SWD for no benefit. - -**But the experiment did not test the hypothesis.** `SWJ_CFG` does not appear anywhere in -CH32H417RM-EN; debug on this part is SDI two-wire on PB8/PB9, while `GPIO_Remap_SWJ_Disable` -(0x00300400) is the legacy AFIO bit covering PA13/PA14/PA15/PB3/PB4. The write was almost -certainly a no-op for the pins that matter, which is exactly consistent with the flat result. So -"the debug function on PB8/PB9 interferes with USB2" is **untested, not refuted** -- and earlier -project work already concluded there is no software off-switch for SDI on this part (no option -byte, no DBGMCU pin control), so there may be no way to test it at all from firmware. - -## Campaign closed (2026-08-14) - -Phase B produced **no measurement** across three attempts. Each one found a real defect in the -harness rather than in the device under test: - -1. Vendor `Hardware()` wedges — the loader-only shim boots and reflashes itself, so the - scaffolding is sound. Unbounded `while (!(RCC->CTLR & RCC_USBHS_PLLRDY));` at - `ch32h417_usbhs_device.c:178` is still the prime suspect (our driver bounds the same wait). -2. The boot-window safety net was unreachable — nothing can trigger a boot once wedged. Fixed by - the IWDG guard, which was then **verified working**. -3. The IWDG was armed *after* the first progress marker, so a fault in that marker left it - unarmed. Fixed by arming it first, with SysTick kicking. Never re-tested. - -Also established: `printf` is unusable in the out-of-tree vendor build (newlib wants a heap this -link never provides), which retroactively explains the silence in all three attempts -- including -the two originally attributed to `Hardware()`. Progress output must use `loader_putc()`. - -**Final state: usbtest 25/30, HIL 11/12, silicon-vs-driver undecided.** The CH569 oracle -(12/12 + usbtest 30/30 under identical usbd, host and rig) remains the strongest result: the -defect is H417-specific and usbd's deferred model is exonerated. Every portable difference from -that oracle has been measured and none moves the drop rate. - -The shim is at `/tmp/vendor-oracle/` (outside the repo) with the watchdog ordering fixed and -markers working, should anyone resume. Note the nano was left bricked by attempt 3 and needs one -Type-A unplug plus `wlink -d 1 erase --method power-off --chip CH32H41X` to restore. - -## Manual re-read: interrupt-flag handling (2026-08-14) - -CH32H417RM-EN chapter 25 has only a feature list (25.1) and register tables (25.2) -- no -transfer-flow narrative -- so the re-read was done as register coverage. Registers our driver -never touches all sit at reset defaults that match the vendor's usage: `UEP_TX/RX_TOG_AUTO` -(manual toggling, as we do), `UEP_TX/RX_BURST`, `UEP_RX_RES_MODE` (ACK, not NYET), `UEP_AF_MODE`, -`TEST_MODE`, `LPM_DATA`, `UEPn_RX_SIZE`, `UEPn_RX/TX_FIFO`. The vendor writes none of them either. - -**One real divergence found: interrupt-flag retirement.** The vendor ISR has *no* `RX_SOF` branch; -SOF falls through to a catch-all that clears the whole `INT_FG` word. Ours tests `RX_SOF` second -and writes back only that bit, and since the hardware sets `RB_UDIF_RX_SOF` every frame, that -branch short-circuits the chain on nearly every interrupt -- leaving `RB_UDIF_FIFO_OV`, `LPM_ACT`, -`BUS_SLEEP` and `LINK_RDY` latched, and delaying `BUS_RST`/`SUSPEND` by one entry. - -Measured, and it does not help: - -| Variant | Pooled drop rate | Verdict | -| -------------------------------------------------- | --------------------- | ------------------ | -| baseline (SOF branch first, clears only RX_SOF) | 34.5% (316), 30.6-39.1% | reference | -| C7c: also clear `RB_UDIF_FIFO_OV` | 40.4% (344), 31.7-47.4% | no benefit | -| C7: full vendor branch order + catch-all | 43.1% (350), 41.7-45.3% | **measurably worse** | - -C7's band (41.7-45.3%) barely overlaps the baseline's, so the vendor's ordering is genuinely worse -here, not noise -- our SOF-first arrangement is the better one. Both reverted; usbtest back to -25/30. The sticky-`FIFO_OV` mechanism is refuted. - -**Retraction:** an earlier pass recorded C7/C7b/C7c as "breaking enumeration". That was wrong -- -the Type-A had been unplugged for the SDI recovery and never replugged, so the board had no host. -A control run of the known-good build failed identically, which is what exposed it. All three -variants enumerate normally. Always run the known-good control before believing a regression. - -## ROOT-CAUSE HYPOTHESIS: the H417 USBHS has no auto-busy, its sibling does (2026-08-14) - -The CH569 driver's init writes: - -```c -R8_USB_CTRL = UCST_HS | RB_DEV_PU_EN | RB_USB_INT_BUSY | RB_USB_DMA_EN; -``` - -and WCH's own header defines that bit as (CH56xSFR.h:1489): - -```c -#define RB_USB_INT_BUSY 0x08 // enable automatic responding busy for device mode or automatic - // pause for host mode during interrupt flag UIF_TRANSFER valid -``` - -**The CH32H417 USBHS control register has no such bit.** RM 25.2.1.1 lists only RB_UD_LPM_EN (7), -RB_UD_DEV_EN (5), RB_UD_DMA_EN (4), RB_UD_PHY_SUSPENDM (3), RB_UD_CLR_ALL (2), RB_UD_RST_SIE (1), -RB_UD_RST_LINK (0), with bit 6 reserved. The part's *USBFS* block does have `USBFS_UC_INT_BUSY` -(0x08), so the feature exists on the chip -- just not on the high-speed controller. - -That is a complete mechanism for everything observed: - -- **CH569**: while a transfer completion is unserviced, the SIE *automatically answers busy/NAK*. - The host retries and the transfer succeeds; a SETUP is never lost. Hence 30/30. -- **CH32H417**: no such fallback. A token arriving while a completion is still pending gets **no - handshake at all** -- exactly the wire signature measured (device completely silent, no - malformed packet, host retries three times, -EPROTO). - -It also explains the three things that made this so hard to chase: - -1. Why **no EP0 register choreography moved the metric**: the drop happens in the window between - a completion and the ISR clearing DONE, regardless of what software writes afterwards. -2. Why the rate **scales with control-transfer density** (63% under a back-to-back `lsusb -v` - hammer vs ~34% during usbtest) -- denser traffic means more windows. -3. Why the failing set is exactly the **control-heavy** cases (9, 10, 13, 14, 21) while every - bulk, interrupt and isochronous case passes: those endpoints tolerate a retry, control SETUPs - do not. - -**Status: strong inference, not a direct measurement.** It rests on WCH's own description of a -bit present on the passing sibling and absent here, plus a symptom that matches exactly. It has -not been confirmed against WCH. - -**Consequence if it holds:** software can only *shrink* the window (ISR latency), never close it, -so 30/30 is not reachable on this controller and the honest outcome is a documented quirk in the -same family as the existing SuperSpeed ones. Note the ISR is already near-optimal for this: EP0 is -`ep_num == 0`, the first iteration of the drain loop, so its DONE is cleared almost immediately. - -## Direct-plug re-test with the sniffer removed (2026-08-14) — HS does not enumerate at all - -With the tap taken out and the nano's Type-A plugged straight into the uPD720201: - -| Build | Result | -| ---------------- | ---------------------------------------------------------------------- | -| `SPEED=super` | **12/12, usbtest 29/29**, CDC 6.3/10.8 MB/s, MSC 191/60.7 MB/s | -| `SPEED=high` | **0/12** -- no USB attach whatsoever | - -High speed produces no enumeration: `dmesg` shows `device descriptor read/64, error -71`, then -`attempt power cycle`, then `new low-speed USB device` (the host reading the idle SDI levels on -PB8/PB9 as a phantom), then `unable to enumerate USB device`, after which the port stays silent. -The chip is fine -- the HS `board_test` build, which never initialises USB, boots and prints its -1 Hz banner normally, and the UART loader keeps accepting firmware throughout. It is specifically -bringing up USB2 that fails. - -**This is the hardware block recorded for this board in July**: PB8/PB9 are simultaneously the -USB2 D+/D- pair and the chip's only SWD/SDI debug pins, and a host's termination and bus-reset -signalling on those pins stops the device attaching. - -**Consequence for everything above: every H417 high-speed measurement in this document was taken -with the ataradov USB2 tap in the cable path.** The tap evidently isolates the pair enough for the -controller to come up; removing it, high speed does not work at all on this board. The driver -fixes and quirk 0x40 are still real and were measured on real hardware, but the configuration in -which they can be observed requires that tap (or equivalent buffering) inline. SuperSpeed -- the -board's supported mode, and the default -- is unaffected and healthy either way. diff --git a/docs/superpowers/plans/2026-08-14-review-findings-remediation.md b/docs/superpowers/plans/2026-08-14-review-findings-remediation.md deleted file mode 100644 index 850aeb3f05..0000000000 --- a/docs/superpowers/plans/2026-08-14-review-findings-remediation.md +++ /dev/null @@ -1,1407 +0,0 @@ -# Review-Findings Remediation Implementation Plan - -> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task.

For this branch the more useful axis is what each finding -costs, which reorders them substantially. Three of the five cheapest findings are the very -instruments used to judge whether the expensive ones are fixed: a usbtest run that renders five -skipped cases as a green full pass, a drop-rate parser that miscounts, and a quirk that never -fires in the configuration it was written for. Those are fixed first because everything else is -measured with them. - -| Class | Findings | Character | -| ----- | ------------------------- | ------------------------------------------------------------- | -| A | F2, F5, F9, F13, F16 | Instrumentation reports unearned success; all new in branch | -| B | F1, F7, F10, F14 | One state machine, four defects; shipping default for hydra | -| C | F3, F4, F6, F8, F12 | Correctness newly exposed by SuperSpeed | -| D | F11, F15 | Not regressions from this branch | - -## Scope decisions - -- **All 16 are in scope.** Nothing is written off as won't-fix. -- **Packaging:** classes A, B and C land in PR #3779. Class D goes to two separate PRs off - `master`, because neither is a regression from this branch and both reach far outside it — - F11 also affects `dcd_nrf5x.c`, F15 changes codegen for ~19 non-WCH families. Keeping them out - leaves #3779 reviewable as a SuperSpeed PR. -- **Validation:** unit tests and builds for everything; hardware sign-off on the CH569 hydra, - including the replug test that is the only real proof of F1. The USB2 sniffer tap stays - unplugged, which bounds what can be claimed — see *Limits* below. - -## Approach - -Point fixes throughout, except for class B, which gets a small state-transition helper. - -Class B's four defects are one root cause wearing four hats: `_fb_state`, the TMR0 interrupt -mask, and the timer registers are three pieces of a single logical state, mutated independently -across six sites in `dcd_ch56x_usb30.c`. Patching them individually leaves the fifth instance -waiting for whoever edits the ladder next. A helper that owns all three makes two of the four -findings unreachable rather than merely fixed, for roughly thirty lines more than the point-fix -alternative. - -A full table-driven rewrite shared between the CH569 and CH32H417 ladders was considered and -rejected as YAGNI. The twins have already drifted — `dcd_ch56x_usb30.c` has six `_fb_state` -writes to the CH32H417's four, and the H417 cannot self-recover once `FB_USB2_ACTIVE` — but that -is a redesign wearing a bugfix costume, and it would need both boards to sign off. The drift is -recorded as a follow-up instead. - -## Section 1 — Class A: make the instruments honest - -**F2 — a quirk-skipped run must not look like a full pass.** `test/hil/usbtest.py` already emits -a `skipped` count; `test/hil/hil_test.py:1338` never reads it, computing `total = passed + failed` -so that a CH32H417 high-speed run with five quirked cases renders `✅ 25/25`, indistinguishable -from a genuine 30/30. Read `skipped`, compute `total = passed + failed + skipped`, and render a -distinct cell (`⚠️ 25/30 (5 skipped)`). Change the failing-case list at `:1346` from -`status != 'PASS'` to `status not in ('PASS', 'SKIP')`, which today reports the five skipped cases -as failures the moment one real case breaks. Exit status stays 0 — a documented quirk is not a -test failure — it simply stops looking like a clean sweep. - -**F5 — the drop-rate parser miscounts.** `test/hil/hs_drop_rate.py:37` accepts a device ACK only -when `usbll.src` starts with `'1.'`, hardcoding wire address 1, while `one_run()` deliberately -captures across enumeration where the device answers at address 0, and xHCI hosts routinely -assign an address other than 1. Test `r[2] != 'host'` instead. Add unit rows at addresses 0, 5 -and 12 — the existing five tests use `'1.0'` throughout and structurally cannot catch this. Record -in the docstring that any drop rate measured before this fix is invalid. - -**F16 — the quirk cannot see the fallback.** `USBTEST_QUIRKS` is selected by which dcd was -compiled in: an SS build has `CFG_TUD_WCH_USBIP_USBHS == 0` and so takes the `0x20` branch, even -though that same image drives the USBHS block at 480 Mbps when `CFG_TUD_WCH_USB30_FALLBACK=1`. -Have `tud_descriptor_device_cb` patch the `bcdDevice` quirk nibble from `tud_speed_get()` at call -time: CH32H417 reports `0x40` at high speed and `0x20` at SuperSpeed, CH569 `0x30` at SuperSpeed -and none at high speed. The compile-time macro remains the default for non-fallback builds. - -**F13 — an interrupted flash strands the board.** `hw/bsp/ch32h417/family.c:161` is `noreturn` and -its first act is to disable the RXNE interrupt and `USART1_IRQn` — the only other way in or out. -Its single exit is `NVIC_SystemReset()` after a CRC-verified session, so an interrupted -`wch_uart_flash.py` leaves the board in the banner loop, off the USB bus, while -`hil_flash.py:246` reports `returncode=0` because the park *write* succeeded. Give the loop an -inactivity timeout: no valid session within ~30 s and it resets into the application. That makes -stranding structurally impossible rather than depending on the rig to rescue it, which is the -part that failed. `reset_wch_uart_loader()` keeps its park window but stops equating a successful -write with a successful reset. - -**F9 — the sudoers drop-in is missing a grant its own tooling needs.** `test/hil/tinyusb-sudoer` -grants eight binaries, none of them `setpci`; `usbtest.py:228` needs it and hard-exits at `:235` -on any Renesas uPD720201/2 xHCI — the controllers the rig uses. Add argument-restricted grants for -`setpci -s 0x6c.l` and for `lsusb`, and add `-n` to `hs_drop_rate.py`'s lone `sudo`, the -only call in `test/hil` without it. - -## Section 2 — Class B: one helper, four bugs - -Introduce `fallback_enter(fb_state_t)` in `dcd_ch56x_usb30.c` as the only writer of `_fb_state`, -owning the timer and the TMR0 interrupt mask with it: - -- `FB_USB3_TRAINING` — set state, start the timer, **enable `TMR0_IRQn`** -- `FB_USB3_UP` — set state, stop the timer -- `FB_USB2_ACTIVE` — set state, stop the timer -- `FB_USB3_OFF` — set state; the timer keeps running for the second expiry - -Convert the six existing mutation sites to call it. - -**F10 is then unreachable.** `fallback_timer_stop()` masks `TMR0_IRQn` and `fallback_timer_start()` -never re-enables it; the only `PFIC_EnableIRQ(TMR0_IRQn)` in the file is in `dcd_int_enable()`. -After a `tud_disconnect()` / `tud_connect()` cycle the timer therefore counts with its vector -masked. The helper makes arming a timer whose vector is masked impossible to express. - -**F1 is not one line.** `_fb_state = FB_USB3_UP` at `:553` is terminal: the TERM_PRESENT-lost -branch at `:600-614` tears the link down and returns without touching the state, and the only -writes back to `FB_USB3_TRAINING` are in `dcd_init` and `dcd_connect`, neither of which usbd calls -on link loss. Replugged into a USB2-only host the board is dead until a power cycle — and this is -the shipping default for `hydrausb3_v1`. Calling `fallback_enter(FB_USB3_TRAINING)` in the -disconnect branch was tried (`d479eddac`) and reverted (`134691e54`): the ladder advances on its -timer whether or not anything is attached, so unplugged it latches `FB_USB2_ACTIVE`, itself -terminal, after ~2.75 s and demotes the board to 480 Mbps on any unplug, including a replug into -the same SuperSpeed host. A fix needs an attach signal that gates the ladder, not a timer; F1 -stays open in `docs/superpowers/todo/pr3779-wch-superspeed.md` (F1). - -**F7 needs an explicit fix**, as no helper covers it. `usb30_hw_reinit_task()` checks -`_fb_state` *before* `link_delay_us(30000)` and never re-checks, while the training-exhausted -branch that sets `FB_USB3_OFF` does not consult `_hw_reinit_deferred` and can land anywhere in -that window. Re-check `_fb_state` after the settle and bail before `usb30_hw_init()` if the ladder -claimed the port meanwhile. - -**F14 overrules a comment written in this branch.** The `LINK_IF_WARM_RESET` branch runs -`usb30_bus_reset()` — deinit, a 30 ms busy-wait, re-init — plus a further million-iteration poll, -entirely in the ISR, defended by a comment arguing that a host-driven reset with a spec'd ~100 ms -window must not depend on application loop timing. But the same file already defers exactly this -work on the TERM_PRESENT path, and 100 ms comfortably covers one task-loop turn. Add the -`ep_state_reset()` / `dcd_event_bus_reset()` that the HOT_RESET branch performs and this one -omits; that missing bus-reset event is a bug independent of where the work runs, and is what -shipped (`d479eddac`). The settle and re-init stay inline in `usb30_bus_reset()`: deferring them -through `usb30_bus_reset_from_isr()`, which deinits synchronously and defers only settle and -re-init, would leave the address-0 write and the `TX_WARM_RST` handshake that follow driving a -torn-down controller, and the deferred re-init would then wipe them. Moving the work needs the -handshake reordered ahead of the teardown, validated on a host that actually issues a warm reset; -see `docs/superpowers/todo/pr3779-wch-superspeed.md` (Out of scope for PR #3779). - -## Section 3 — Class C: correctness - -**F3 — `dcd_edpt_clear_stall()` must not resurrect a retired transfer.** It re-arms on the stated -assumption that the class driver still considers the transfer submitted, but `usbd.c:1846-1850` -clears `BUSY` *and* `CLAIMED` on a was-stalled clear, and `vendord_abort_ep()` is literally -`stall(); clear_stall();` used to abort on every `SET_INTERFACE`. Drop the re-arm; the class -resubmits, which `examples/device/usbtest` does on its next tick. Same fix in the CH32H417 twin, -where `dcd_edpt_stall` likewise never clears `xfer->valid`. The hydra adjudicates this via usbtest -cases 13 and 29 — the cases the original re-arm was added for. - -**F4 — the OUT completion drops its only interlock too early.** `dcd_ch32h417_usbhs.c:553` clears -`RB_UEP_R_DONE` before `EP_RX_LEN` is sampled and before `queue_out_packet()` reprograms the DMA -address, leaving the endpoint ACK-armed at the finished packet's address. The CH56x twin is immune -by hardware — it sets `RB_USB_INT_BUSY` and clears `R8_USB_INT_FG` only after `update_out()` has -re-armed — and CH32H417 RM 25.2.1.1 lists no equivalent bit. Clear `DONE` after `update_out()` -returns, mirroring where the CH56x driver clears its flag. - -**F6 — MTP's ZLP threshold assumes 512.** `mtp_device.c:426` falls back to a hardcoded 512 because -`ep_sz_fs` is only written when `tud_speed_get() == TUSB_SPEED_FULL`, while `TUD_MTP_SS_DESCRIPTOR` -arms 1024. A data phase ending in exactly 512 bytes then queues a ZLP the host reads where the -response container belongs. Store the real bulk max packet size at open for every speed and use it -as the threshold. - -**F8 — `midi2_device` stalls a mandatory request.** This branch gives it a high-speed -configuration (master had none) without `tud_descriptor_device_qualifier_cb` or -`tud_descriptor_other_speed_configuration_cb`, so `usbd.c` stalls EP0 on -`GET_DESCRIPTOR(DEVICE_QUALIFIER)` — which USB 2.0 §9.6.2 forbids for a high-speed-capable device. -Add both callbacks, following every other example that carries an HS config. - -**F12 — the new per-function remote-wake state is write-only.** `func_wakeup_bm` is written at -`usbd.c:1305/1307` and read only by the aggregate loop at `:1312`; interface `GET_STATUS` at -`:1288` still returns a hardcoded `0x0000`, so a wake-capable function reports itself -non-capable, contrary to USB 3.2 §9.4.5. Return D0/D1 at SuperSpeed, keeping the two reserved zero -bytes at USB 2.0 speeds. Separately, the state survives `SET_INTERFACE`, a same-value -`SET_CONFIGURATION` (which Linux's `usb_reset_configuration()` sends) and `SET_ADDRESS(0)`, all of -which USB 3.2 Table 9-10 marks as resetting FUNCTION REMOTE WAKEUP; clear it on each. - -## Section 4 — Class D: two separate PRs off master - -**F11 — MSC discards a result the branch made meaningful.** `usbd_defer_func()` now returns -`bool` precisely so a dropped deferral is visible, but `msc_device.c:331` ignores it and returns -unconditional `true`. `proc_async_io_done` is the only place `pending_io` is cleared on the async -path, so a full event queue hangs the transfer forever while the application is told the -completion was accepted. Propagate the result. Not a regression — it was equally dropped when the -return was `void` — hence its own PR. The identical exposure at `dcd_nrf5x.c:155` and `:190` is -noted as follow-up, not fixed here. - -**F15 — the `-w` change leaks family flags into unrelated BSPs.** `family_support.cmake:451` -changed from a property assignment to `APPEND`, so every family's `BOARD_TARGET` compile options -now reach the BSP library's own sources.

This is a strong inference from -WCH's documentation, **not confirmed with WCH**, and it explains why no EP0 register change -ever moved the rate: the drop precedes anything software can do. - -Ordinary class traffic is unaffected because host retries absorb it -- all twelve HIL device -examples pass at CDC 5.8/6.5 MB/s and MSC 25.2/10 MB/s. Only usbtest's control stress exposes -it. - -What the campaign did establish: - -- **The CH569 oracle is real**, re-measured today at 12/12 + usbtest 30/30 including 13, 14 - and 21, under identical usbd, host and rig. usbd's deferred status-stage model is - exonerated and the defect is H417-specific. -- **No portable difference from that oracle moves the drop rate**: baseline 34.5%, status - pre-arm removed 32.8%, correctness fixes 37.7% — all inside the per-run band. -- **The one difference that could explain a SIE-level drop is not portable**: CH569 has a - dedicated `RB_USB_IE_SETUPACT` interrupt; the H417 silicon has none. -- **Phase B was attempted and aborted** — the vendor demo bricked the board (details in - `docs/superpowers/notes/h417-ep0-diff.md`), needing a physical cable pull to recover. - -Silicon-vs-driver therefore remains formally **undecided**: the hardware limitation above is -the strongest inference, not a verdict. The Phase B retry recipe in the notes is the only -remaining way to settle it. - -## Pre-campaign baseline - -The starting state this plan was written against; the outcome above supersedes it. - -| Item | Value | -| ------------------------ | ------------------------------------------------------ | -| HIL device suite (HS) | 11/12 | -| usbtest (HS, fresh flash)| 25/30 | -| Failing cases | 9 ch9-subset, 10 queued-control, 13 ep-halt, 14/21 ctrl_out | -| Throughput | CDC 5.8/6.5 MB/s, MSC 25.2/10.1 MB/s | -| SuperSpeed path | untouched; the HS file compiles to nothing at `SPEED=super` + `FALLBACK=0` | - -At the baseline, quirk flags were gated on `CFG_TUD_WCH_USBIP_USB30`, so at high speed none -were advertised: all 30 cases ran. Both quirks then existing describe SuperSpeed errata -(`0x10` → cases 14/21, `0x20` → case 13), and the HS failing set was exactly those plus 9 -and 10. The campaign added `0x40`, advertised at high speed, which skips all five. - -## The blocker - -The SIE intermittently gives **no handshake at all** to a SETUP. A SETUP may not be NAKed or -STALLed, so the host retries three times ~124 µs apart and fails the transfer with -`-EPROTO`/`-EIO`. Wire-confirmed; the device is completely silent on a dropped attempt, with -no malformed or bad-CRC packets. - -A dropped SETUP is harmless alone — the host retries. A case fails only when **all three** -attempts drop. At a ~37% drop rate that is ~5% per transfer, and case 9 alone issues 1000 -control transfers. **The target is therefore a drop rate near zero, not merely lower.** - -Related mechanism already measured: after a control-IN data stage completes, the host sends -the status ZLP in the very next microframe, but usbd submits it a `tud_task` round-trip -later, leaving EP0 RX at `RES=NAK` across the gap. On the wire the host retried the status -OUT for ~750 µs, PINGing in between, while the SIE answered PING with ACK from the RES field -and still refused the data. - -## Measurement rules - -Non-negotiable. Violating these produced a phantom bug, two harmful "fixes", and one -unproven headline number across three review rounds. - -| Rule | Why | -| ------------------------------------------------------- | --------------------------------------------------------------------- | -| Capture wire and UART in the **same run** | Separate runs produced the phantom "duplicate SETUP" finding | -| Always start from a **fresh flash** | Drop rate drifts 44% → 71% over ~3 min of uptime | -| Pool **≥300 SETUPs** per config; interleave A/B/A | A single ~90-SETUP capture spans 44–71% on one unchanged build | -| Gate flashing on **build success** | A failed build silently flashes the stale binary | -| Judge by **wire drop rate**, not usbtest pass count | usbtest is noisy at 24–25/30 | -| Revert any change that does not move the pooled metric | The failure mode of the last session was accumulating unproven edits | - -Primary metric: pooled SETUP drop rate from a fresh flash. -Acceptance metric: usbtest 30/30 on three consecutive runs, **each from its own fresh flash** -(the drift makes a single flash followed by three runs a weaker claim). - -## Phase 0 — re-establish ground truth - -No code changes. Two facts this design leans on are memory claims, not present-day -measurements: - -1. **CH569 at HS is 30/30.** Flash the hydra with the HS `usbtest` build and run the - battery. If it is not 30/30 today, Phase A loses its oracle and we go straight to Phase B. -2. **The H417 failing set is stable.** Three fresh-flash runs to confirm 9/10/13/14/21 is - the real set rather than a noise band. - -## Phase A — differential against the CH569 driver - -Assuming Phase 0 confirms it, `dcd_ch56x_usbhs.c` reaches 30/30 under *identical* usbd — so -the deferred status-stage model is survivable and something in the H417 EP0 path differs. -Compare the two state machines on four axes: - -- **SETUP detection and acknowledgement** — how each learns a SETUP arrived, and what it writes back -- **Status-stage arming** — when EP0 RX becomes ACK-armed relative to the data stage completing -- **Toggle management** — CH569 uses hardware auto-toggle for data endpoints; H417 drives it manually per arm -- **Response/DONE bookkeeping** — order of clearing, and what runs in ISR versus task context - -Each difference becomes one candidate change, applied **one at a time**, judged by pooled -drop rate. Changes that do not move the metric are reverted, not accumulated. - -usbd core changes are authorised. One candidate is explicitly in scope: letting the DCD -complete the EP0 status stage without waiting for a `tud_task` round-trip. - -## Phase B — vendor oracle (only if Phase A falls short) - -Build `hw/mcu/wch/ch32h417/EVT/EXAM/USBHS/DEVICE/SimulateCDC-HID` unmodified — the only SDK -family that handles a multi-packet EP0 OUT, which is what cases 14/21 exercise. Build -out-of-tree with the riscv toolchain plus `hw/bsp/ch32h417/linker/ch32h417_v3f.ld`. -**Nothing under `hw/mcu/` is edited.** Run the same control hammer and measure its pooled -drop rate. - -- Vendor **also drops** → silicon. Literal 30/30 is unreachable. Deliver the verdict with - evidence and propose extending quirks `0x10`/`0x20` to high speed as a follow-up decision - for the maintainer. -- Vendor is **clean** → the difference is in our EP0 path, and their register sequence is the - map to transcribe. - -## Verification - -- usbtest **30/30 on three consecutive runs, each from its own fresh flash** -- Full HIL device suite on the nano at HS: 11/12 at the baseline, must be 12/12 -- **SuperSpeed regression**: nano SS suite (12/12 + usbtest 29/29) unchanged. Free today - because the HS file compiles out at `SPEED=super`; **not free if a usbd core change lands** -- **If usbd core changes**: CH569 SS and HS, plus at least one non-WCH board - (`stm32f407disco` or `raspberry_pi_pico`) to catch fallout on other ports -- `ceedling` unit tests and `pre-commit run --all-files` - -## Exit conditions - -- **Done** — acceptance bar met and regressions clean. -- **Stop and report** — the vendor oracle shows silicon, or a fix would require modifying - vendor SDK files. In both cases the deliverable is the evidence plus a recommendation. - -## Out of scope - -The SuperSpeed path, the CH569 port itself, and the uptime drift as a standalone -investigation.
