The repo's documentation framed it as a support repo for one product (WardenOS). Since going public the real audience is anyone with a Luckfox Pico 86 Panel: a maintained 6.18 kernel, an off-device development loop, and a device simulator that exist nowhere else for this board. Reframe the README and top-level docs board-first, with WardenOS documented as the downstream consumer it is (ADR-0008). Also an editorial pass over the whole doc set: - every H1/H2 is now a short title, not a sentence (ADRs, qemu/, patches/, drivers/, architecture, NPU feasibility, config-lint, payload); workflow flowchart titles fixed at the source in tools/flowgen.py and regenerated with fresh bench numbers - README Quick Start commands verified against the scripts; requirements corrected (curl, bare python, gcc >= 14) and the MC/DC gate added as a step (run green locally on gcc 14.2) - dropped the 'needs python (not python3)' vendor dig: build-kernel.sh inherited the same requirement (filed #10 to remove it) - glossed MC/DC and HPMCU on first use; marked the tests/uboot-ab reference as flare-edge; deduplicated the three-simulator list into the root README table
The Kernel Patch Series
The delta that forward-ports the vendor Rockchip 5.10.160 RV1106 support onto a
pristine upstream linux-6.18.46, as a reviewable, subsystem-split series. Every
patch applies cleanly onto pristine 6.18.46 (git apply --check), and the whole set
reproduces the 223-file / ~136K-line delta that boots and is hardware-verified on
warden-c8a3 (see ../kernel/rv1106-enablement/).
Build it with ../build/build-kernel.sh (fetch pristine → apply these → configure
with ../build/warden_defconfig → zImage + rv1106-warden.dtb).

License
Everything in this directory is a derivative work of the Linux kernel and of
GPL-2.0 vendor kernel code: GPL-2.0-only (or the per-file SPDX identifier
where one is present), the same license the whole repository carries. Per-driver
origin and license are tracked in kernel/rv1106-enablement/PROVENANCE.md.
Provenance & regeneration
Baseline: linux-6.18.46 from kernel.org (build/linux-6.18.46.tar.xz.sha256
pins the tarball). The series was generated by overlaying the hardware-verified
source tree onto pristine (build artifacts excluded) and splitting git diff by
subsystem. Licensing/origin of each block is tracked in
../kernel/rv1106-enablement/PROVENANCE.md.
Whitespace: 60-wifi-aic8800.patch carries the vendor blob's trailing-whitespace
verbatim; git apply --whitespace=nowarn (the build wrapper) accepts it. Do not
re-flow vendor code — it must stay diffable against future vendor drops.
