CLKS Kernel

English | 简体中文

CLKS is the standalone kernel repository used by CLeonOS. It contains architecture startup code, interrupt handling, memory management, scheduler, syscall/runtime layers, storage, TTY/console, and kernel support libraries.

Status

CLKS now builds as an independent repository.

• Kernel build no longer depends on CLeonOS userland sources.
• menuconfig assets are local to this repository (configs/menuconfig, scripts/menuconfig.py).
• CMake helper scripts are local to this repository (cmake/).

Build

make kernel

Build symbols map:

make kernel-symbols

Direct CMake:

cmake -S . -B build-cmake -DCMAKE_BUILD_TYPE=Release
cmake --build build-cmake --target kernel

Menuconfig

make menuconfig

or GUI mode:

make menuconfig-gui

Outputs are generated under configs/menuconfig/.

CI

build-kernel workflow builds clks_kernel.elf and kernel.sym on push/PR.

Integration With CLeonOS

In the CLeonOS mono-repo, CLKS should be referenced as a git submodule. The main repo should only track the submodule pointer and delegate kernel build to this repo.
