NebulaOS-kernel

Role in NebulaOS: Linux 6.6 kernel SDK for the Creality Ender-3 V3 KE / Ingenic X2000 platform. Every kernel-source change NebulaOS made lives here as a real, reviewable commit — not as a patch file applied at build time.

Canonical branch: openke (the name is historical — this repo predates its NebulaOS rename and kept its original branch name; see Branch Model). main tracks the unmodified upstream SDK.

Complete OS build: No. NebulaOS-firmware pins an exact commit of this repo's openke branch, fetches it as a sparse checkout, and applies 8 accepted build-time kernel variants on top before compiling. Building this repo alone does not produce a working printer image.

• NebulaOS-guppyscreen — touchscreen UI fork

Audience: Developers and advanced testers.
