Preparing the repo to go public (ADR-0007): - CI: kernel-build moves from the self-hosted runner to ubuntu-latest (installs its own cross toolchain + qemu, caches the pristine tarball). On a public repo a registered self-hosted runner is reachable from approved fork-PR workflows — i.e. arbitrary code on private infrastructure — and the build never actually needed the SDK host. ADR-0004 marked superseded-in-part; docs/ci-cd.md rewritten (site specifics now live only in the private deployment log). - Licensing: LICENSE gains the GPL-2.0 carve-out for patches/ and the kernel source excerpts (Linux derivatives; per-driver provenance was already tracked in PROVENANCE.md); patches/README.md states it too. - Scrubbed from the tip: bench-unit dev credentials and its gadget IP (m2-boot notes), the site AP SSID+BSSID and a neighboring AP's BSSID and the device WLAN MAC (wifi bring-up evidence — BSSIDs are geolocatable), the runner mesh IP. NOTE: these remain in git history; decision on a pre-publication history rewrite is separate. - Emoji cleanup across 21 tracked files (kernel port docs, review report, enforce-mcdc.sh) per repo text conventions: status marks became [x]/[wip]/[ ]/OK plain text. - "[maintainer]-gated" process phrasing normalized to "maintainer-gated" (attributions in dated evidence docs kept). Verified: zero emojis tracked; scrub grep clean; patches carry no internal references; ci.yml parses; shellcheck unchanged.

# RV1106 6.18 driver parity vs the 5.10 vendor kernel
|
||
|
||
Goal: every driver the panel's 5.10 kernel runs must work at ≥ parity on our
|
||
self-built 6.18. Source of truth = the running 5.10 system on warden-c8a3
|
||
(`lsmod` + `/proc/interrupts`, captured 2026-08-24). Verify each on hardware via
|
||
the A/B `_b`-slot loop (`../docs/m2-boot-on-c8a3.md`); [x] means confirmed on
|
||
c8a3, not just compiled.
