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.

• 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

• ARM32
• • Cortex-M class cores (armv6m - armv8m)
• • ARMv7+ Cortex-A class cores
• ARM64
• RISC-V 32 and 64bit bit in machine and supervisor mode
• x86-32 and x86-64 386 up through modern cores
• microblaze
• MIPS
• OpenRISC 1000

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

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

Note: for ubuntu x86-64: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from https://newos.org/toolchains/x86_64-elf-10.2.0-Linux-x86_64.tar.xz
