CLKS is the kernel component of the CLeonOS project.
It includes architecture startup code, interrupt handling, memory management, scheduler, syscall layer, storage, TTY/console, and core runtime services.

Status

CLKS can be built in kernel-only mode from the current mono-repo, but it is not yet a fully independent repository build system.

Kernel-only mode is available.
Userland/ISO targets are optional and can be disabled.
Some build scripts are still shared at repository root (cmake/, configs/, scripts/).

Directory Layout

clks/
|- arch/          # Architecture-specific startup and low-level code
|- include/       # Public kernel headers
|- kernel/        # Core kernel subsystems
|- rust/          # Rust staticlib used by kernel
|- third_party/   # Embedded third-party sources used by kernel
|- CMakeLists.txt # Kernel build rules
|- Makefile       # Kernel-focused wrapper (delegates to root build)

Build (Kernel-Only)

From repository root:

make kernel CLEONOS_ENABLE=OFF

or via CLKS wrapper:

make -C clks kernel

Menuconfig (CLKS Scope)

make menuconfig-clks

or:

make -C clks menuconfig

This updates CLKS-focused config outputs under configs/menuconfig/ (including config.clks.cmake).

Notes for Future Split

To make CLKS a standalone repo, the next required step is moving shared build assets into clks/ (or vendoring equivalents), especially:

cmake/ helper scripts (log.cmake, symbol generation, tool checks)
boot config and image packaging pieces currently under configs/
menuconfig launcher and feature metadata currently under scripts/ and configs/menuconfig/
