The .c/.dts/.frag files here are a point-in-time port-provenance snapshot (with
standalone test programs + instructional fragments the narrative docs reference),
not a maintained second copy of the kernel delta. Add a prominent canonical-source
note so the snapshots (which can lag the final series, e.g. the clk CLK_IGNORE_UNUSED
fix) are never mistaken for current code. patches/ + build/build-kernel.sh remain the
single source of truth.

The kernel build itself is the gate; uploading the zImage/dtb can fail on an
account-wide GitHub artifact-storage-quota hit unrelated to the build. Mark the
upload continue-on-error so a good build isn't red-X'd by it. Outputs also remain
on the self-hosted runner host.
Verified: kernel-build compiled the RV1106 6.18.46 kernel end-to-end on
bfe-mpc-0640 (zImage 8.25 MB + rv1106-warden.dtb 37 KB); the patch series applied
(issue #1 fix confirmed).

The kernel-build job set WORK inside the repo checkout, so build-kernel.sh's
`git apply` ran from a subdirectory of the warden-sdk git repo — where git apply
silently ignores out-of-subdir paths and exits 0 without applying anything. The
build then failed at the (never-created) rv1106-warden.dtb target, and the
unconditional `echo "applied"` had masked it.
- ci.yml: WORK -> ${{ runner.temp }}/kbuild-out (outside the checkout); artifact
paths follow.
- build-kernel.sh: the patch loop now fails loudly instead of echoing on silent
failure, and a post-apply sentinel assert (rv1106-warden.dts must exist) makes a
silent no-op impossible to ship — the regression guard for this class.
Refs #1.

Make the self-hosted kernel-build runnable with zero manual toolchain/python setup
on the runner host (docs/ci-cd.md steps 3-4 move into the workflow):
- build/build-kernel.sh: honor a caller-provided CROSS_COMPILE (default stays the
Luckfox uclibc prefix). The kernel is freestanding, so a generic arm cross
compiler links it.
- kernel-build job: set CROSS_COMPILE=arm-linux-gnueabihf- (Debian
gcc-arm-linux-gnueabihf, already on 0640) instead of depending on the ephemeral
SDK checkout path; symlink python->python3 into $RUNNER_TEMP/bin on $GITHUB_PATH
for the bare-`python` SDK quirk.
- docs/ci-cd.md: only steps 1-2 (systemd service + cgroup cap) still need 0640 sudo.

Second recursive pass: two adversarial re-reviewers verified the iteration-1 fixes.
Fuzz/empirical checks cleared the freshness min-budget rewrite (200k random trials),
the config-lint reg-token scanner, its UTF-8 boundary safety, and the build-kernel.sh
trap (5 exit scenarios) — no defects. Three items corrected here:
- config-lint is_known_safe_loader: match the WHOLE normalized loader name, not an
unanchored substring. The iteration-1 allowlist swap kept `contains()`, so a future
coprocessor whose name merely contained a boot word ("AudioLoader" ⊃ "loader",
"SplRtos" ⊃ "spl", "Bl32" ≠ "bl31") would have been waved through — reopening the
0x40000-brick false-negative the fail-closed change exists to prevent. Regression
test added with those exact adversarial names.
- docs/architecture.md §3: the `cru` bullet no longer claims flared's devmem `Bus`
seam is shipped — it lands when flare-edge consumes warden-sdk ([maintainer]-gated), which
is what §7 item 3 already said. Resolves an in-document contradiction.
- drivers/README.md: modbus "11 pty scenarios" -> "8 pty scenarios + 3 wire/daemon
checks (11 total)", matching flare-edge tools/modbus-sim's actual SCENARIOS list.
- docs/decisions/0002-mcdc-tiering.md: Consequences now describe the shared
drivers/enforce-mcdc.sh + drivers/<name>/test/ layout actually built (not the
per-driver dirs the ADR first anticipated); Rust MC/DC tooling reality noted.
config-lint: 9 tests pass; clippy clean under -D warnings; gitleaks clean. C drivers
untouched (still relays 40/40, freshness 66/66 MC/DC).

First recursive code-review-harness pass over the authored SDK code (sim/,
config-lint, flowgen, drivers/{relays,freshness}, build/, ci.yml). Four parallel
dimension reviewers; all findings at every severity corrected per workspace rule.
Correctness / reliability:
- freshness.c min_budget_ms: use a `seen` flag, not `best==0`, as the empty
sentinel — a zero-tolerance (max_stale_ms==0) binding was silently widened to a
looser neighbour's budget. Regression test added; still 66/66 MC/DC.
- config-lint parse_reserved_ranges: match `reg` as a whole property token (ident
boundary before, `=` after) so `reg-names` / a `region-*` label no longer
mis-parses into a bogus reserved range.
- config-lint loader check: fail closed — flag any loader with a LOAD_ADDR that is
not a known-safe boot component, instead of only known MCU names, so a future
coprocessor ("Rtos"/"Bl32") can't slip past the 0x40000-brick gate.
- build-kernel.sh: sha256 verification is now mandatory (refuse to build if the pin
is missing) and the mktemp scratch tree is removed on exit (trap), while a
caller-provided WORK is left intact for CI artifact upload.
Test quality:
- freshness: added the age==max_stale boundary case and a clock-wraparound
(now < last_ok) fail-safe-to-UNKNOWN test.
- relays: unsetenv(WARDEN_GPIO_ROOT) at main() so the NULL-env arm is hermetic.
Security / CI:
- ci.yml: top-level `permissions: contents: read` (badges overrides to write);
pin taiki-e/install-action to commit SHA (v2.86.7).
Maintainability / docs:
- drivers/enforce-mcdc.sh: one shared, name-derived gate replaces the two
copy-pasted per-driver scripts; Makefiles call ../../enforce-mcdc.sh.
- docs/architecture.md: §3/§4/§6/§7 rewritten to match reality — NPU/RGA models,
config-lint, and the relays+freshness MC/DC harnesses are done; kernel §6 now
reflects the 5.10->6.18.46 forward-port (ADR-0001), not the superseded plan44/6.6.
- README: status blurb + layout table corrected (kernel/, .github/; stale ci/ and
patches/ descriptions fixed). hpmcu "8 tests" -> 7 in docs.
- freshness.{c,h}: ADR reference points at flare-edge ADR-0004 (warden-sdk's
ADR-0004 is the CI runner — number collision).
- normalize rustfmt drift across sim/ + config-lint.
All green: sim 37 tests, config-lint 8 tests, both drivers 100% MC/DC (relays
40/40, freshness 66/66), clippy clean under -D warnings, gitleaks clean.

- drivers/README.md: honest Tier-1 (relays + freshness, 100% MC/DC here now) vs

freshness.c (ADR-0004 freshness-contract engine) is pure logic via produce/render
callbacks — no hardware seam needed, the callbacks are the seam. Host harness reaches
100% MC/DC (66/66 conditions, 100% lines, 27 checks) by driving warden_fresh_decide
directly + the bind/tick/invalidate/min-budget state machine through fakes, with
-DFRESH_MAX=2 so the table-full and unused/hidden-slot arms are reachable. Directly
serves future-features-2's "never a stale number in the UI" requirement. The CI mcdc
job now enforces relays + freshness.

mailbox, pvtm, rknpu, rga, aic8800 wifi, audio codec, thermal/rtc/adc/gmac/touch).
Verified: every patch applies cleanly onto pristine (git apply --check), the full

builds the warden dtb + rockchip DRM drivers (rc=0).
- build/build-kernel.sh: fetch+verify pristine (sha256-pinned) -> apply series ->

MAILBOX (fully open A7<->RISC-V SCR1 round-trip, 5/5 exact echoes on c8a3):
- rockchip-mailbox.c: rv1106 has 1 shared IRQ, not 4/channel -> added
rv1106_drv_data{num_chans=1} + compatible (rk3368 fallback assumed 4 -> probe
failed 'IRQ index 1 not found').
- clk-rv1106.c: CLK_CORE_MCU (SCR1 core clock) marked CLK_IGNORE_UNUSED -
6.18's clk_disable_unused() was switching off the coprocessor clock so a
loaded firmware never ran (5.10 left it on).
- Open SCR1 echo firmware (scr1-echo/, 154B RV32IMC) + load/test scripts;
A2B_INTEN on the MCU side + CMD-then-DAT (DAT=doorbell) order. Loaded via the
proven hpmcu.rs SRAM path; do NOT kill warden-flared (dw-wdt). mailbox/VERIFIED.md.
NPU (open GPL rknpu 0.9.2 kernel driver on 6.18):
- DT fix: base npu node lacks interrupt-names, driver requests IRQ byname
'npu_irq' -> probe bailed -ENXIO. Added interrupt-names='npu_irq'.
- Verified: [drm] Initialized rknpu 0.9.2 on minor 1; /dev/dri/card1;
rknpu_version_test PASS (0.9.2 + hw version, full power/clock/reset path).
- Honest ceiling: open compute (regcmd compiler) is a from-scratch ~person-year

Ported rv1106_codec.c (acodec) + rk_dsm.c (built, dsm disabled — panel uses
acodec) into 6.18 (6 ASoC API-delta fixes: gpiod, volsw unify, DAIFMT CBC/CBP

Fixed the subagent's gap: cpu DAI SND_SOC_ROCKCHIP_I2S_TDM was left =m (module,

On-hardware proof (self-built 6.18.46, _b slot): aic8800 modules load,
download firmware, wlan0 up ([device-mac]), iw scan finds real APs
incl. SSID BlueFlare @ -43dBm. RF path fully functional. See
wifi/VERIFIED-on-c8a3.md.
Two changes from the initial built-in attempt:
- Built-in =y DEADLOCKS: aicbsp_init's eager SDIO bring-up (device_initcall,
sequential) blocks the dw_mmc controller probe that would enumerate the
card it waits for (aicsdio.c:597 2s down_timeout -> unregister). Converted
to modules (=m): AIC_WLAN_SUPPORT bool->tristate; loaded late, after the
mmc-pwrseq enumerates the card — the vendor-proven flow.
- Restored fdrv's own md5.o (each .ko needs its own MD5; bsp doesn't export
it). Refreshed kbuild snapshot accordingly.
Kernel-size fix (CONFIG_KERNEL_GZIP -> XZ): the wifi kernel's 12.12MB gzip
zImage overran U-Boot's DTB-at-0xc00000 load boundary (Sysmem Error, FLARE-AB
fell back to _a). XZ -> 8.15MB, ~4MB headroom; also correct for a firmware
kernel. Uncompressed Image ~30MB but the ARM decompressor relocates the FDT
at runtime, so only the U-Boot load-time overlap mattered.
DRIVER-PARITY: wifi ✅ M5; BT 🔨 (module built, HCI not yet exercised).

Capabilities audit — classify every RV1106 SoC block against a 6.18 driver:
GMAC (wired eth, enabled on-board), crypto-v3, trngv1 (hw RNG), OTP, mailbox,
NPU, audio codec/DSM, pvtm still to port; camera/ISP + SPI are N/A (no HW).
Provenance ledger — per [maintainer]'s openness directive extended to already-ported
drivers: every ported driver is GPL-2.0 kernel source (vendor-src or
mainline-sibling); the only binary in the whole path is on-device wifi-chip
firmware, which by construction cannot be host source. No vendor binary is

RTC: ported the vendor rockchip,rv1106-rtc driver (rtc-rockchip.c) to 6.18 — one
API delta (rtc_register_device -> devm_rtc_register_device). Verified on
warden-c8a3: /dev/rtc0 registers and reads.
tsadc thermal: ported the rv1106 data + rk_tsadcv9_initialize + the TSADCV9/VOGRF
macros + code table from the vendor; adapted .chn_id[SENSOR_CPU] -> .chn_offset
for 6.18. Verified: thermal_zone0 "soc-thermal" reads 39.8 C.
i2s-tdm: rv1126 fallback compatible added (DAI builds; sound card needs the acodec
port next). saradc still -22 (clk-rv1106 SARADC divider — deferred).
Includes the NPU + RGA open-source port plans (research): rknpu kernel driver is a
small port (RV1106 config already in the vendor driver; 4 dead-code headers need
compat stubs) but no open userspace exists for this NPU gen; RGA = port the vendor
char-dev rga3 driver (WardenOS's librga uses /dev/rga, not V4L2), + a cma pool +
hrtimer_setup. All ports are open source (vendor C source / mainline siblings).

needed, zero capabilities left on the table. Priority: AIC8800 wifi/BT, RGA,
rknpu, RTC, tsadc, i2s, saradc-fix, eth0-gadget, then a full capabilities audit.

usb2phy: ported the RV1106 inno-usb2 phy config to 6.18 (rv1106_usb2phy_cfg;
fields map 1:1 except utmi_iddig->utmi_id and chg_mode->opmode; 5.10-only
iddig_output/en/bvalid_grf_sel dropped; phy_tuning left off, guarded so safe).
With PHY_ROCKCHIP_INNO_USB2=y + the u2phy/usbdrd/dwc3 DT enabled, verified on
warden-c8a3: the DWC3 comes up as xhci-hcd @ 0xffb00000 — USB host works. eth0
gadget just needs dr_mode=peripheral.
saradc: added rv1106_saradc_data (2-ch v2, matches the vendor) + the native
compatible. Driver now matches; probe still returns -22 (a clk-rate/setup detail,
not the data) — TODO.
Also captured: the growing board dts (USB nodes), the port fragments under usb/

The RV1106 VOP is the RV-series "lite" VOP (rockchip,rv1106-vop, VOP_VERSION 2.0xc),
mainline's VOP1 driver. Its sibling rv1126 is already in 6.18, so rv1106_vop reuses
rv1126's register sub-structs + VOP_FEATURE_INTERNAL_RGB + the smaller raster.
Verified on warden-c8a3: with the driver delta + DT (vop enabled with named
"ahb"/"dclk" resets, vop_out repointed to a panel-dpi 720x720 node, pwm-backlight
on pwm1), the VOP BINDS and DRM initialises (/dev/dri/card0), and the PWM backlight
comes up. The register data / version / feature / resets are validated.
Open: /sys/class/drm/card0 has no connector yet — rockchip_rgb_init isn't producing
one ("Cannot find any crtc"). Last mile of M4; needs a debug print in rgb_init + the
panel bus_format, and the pixels must be verified on the physical panel (can't be
checked over serial/ssh). Full recipe + next steps in display/README.md.
Also batch-2 config: GPIO_SYSFS, PWM_ROCKCHIP, crypto (aes/ccm/ctr/arc4), CFG80211,
DRM_ROCKCHIP/ROCKCHIP_VOP all =y; PSCI-style SMC removed via the psci-node deletion.

Move from the hand-built minimal DT to the vendor rv1106.dtsi (full SoC:
pinctrl, gpio×5, dmac, cru+grf_cru, all peripherals), with our lean board DTS
(rv1106-warden.dts) enabling only the wall-HMI's needs — no camera/ISP/CSI.
Two deltas made it boot on 6.18: overwrite boot-mode.h with the vendor's (extra
BOOT_* constants) and DELETE the psci node (no secure monitor → SMC fault →
"Attempted to kill the idle task"). Recipe in dts/README.md.
Verified on warden-c8a3 (uname 6.18.46, full WardenOS userspace): pinctrl,
gpio0-4, pl330 DMA, uart1/2/4 (ttyS1/2/4), i2c3, dw-wdt (watchdog0) all probe.
DRIVER-PARITY.md tracks the remaining ports (VOP display, AIC8800 wifi, rknpu,
usb2phy, saradc-compat, RGA) toward full parity with the 5.10 kernel.
