The Little Kernel Embedded Operating System

The LK kernel is an SMP-aware kernel designed for small systems ported to a variety of platforms and cpu architectures.

See https://github.com/littlekernel/lk for the latest version.

High Level Features

Fully-reentrant multi-threaded preemptive kernel
Portable to many 32 and 64 bit architectures
Support for wide variety of embedded and larger platforms
Powerful modular build system
Large number of utility components selectable at build time

Supported architectures

ARM32
- Cortex-M class cores (armv6m - armv8m)
- ARMv7+ Cortex-A class cores
ARM64
- ARMv8 and ARMv9 cores
RISC-V 32 and 64bit bit in machine and supervisor mode
x86-32 and x86-64
Motorola 68000
Microblaze
MIPS
OpenRISC 1000
VAX (experimental)

TODO

To build and test for ARM64 on linux

install or build qemu. v2.4 and above is recommended.
install gcc for arm64 (see note 1)
run scripts/do-qemuarm -6 (from the lk directory)
you should see 'welcome to lk/MP'

This will get you a interactive prompt into LK which is running in qemu arm64 machine 'virt' emulation. type 'help' for commands.

Note: for ubuntu x86-64 sudo apt-get install gcc-aarch64-linux-gnu or fetch a prebuilt toolchain from https://newos.org/toolchains/aarch64-elf-14.1.0-Linux-x86_64.tar.xz
