To build and test for ARM64 on linux

  1. install or build qemu. v2.4 and above is recommended.
  2. install gcc for arm64 (see note 1)
  3. run scripts/do-qemuarm -6 (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 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
