LK Code walkthrough

This repo hosts forked LK repo with some minor tweaks to make the qemu based ARM64 target boot on Github codespaces environment

The main goal is:

• Setup a clean environment on Codespaces (removing dependency on personal device) and maintaining a coherent and working setup
• Little tweaks here and there to experiment and track the flow while walking through the codebase
• Understand what goes under the hood when LK boots and how it interacts with the system (mainly focusing on ARM64 based systems)

Instructions

• Open up the Github codespaces.
• Install dependencies:
  • sudo apt update
  • sudo apt upgrade
  • sudo apt install qemu-system-aarch64
  • sudo apt install gcc-aarch64-linux-gnu
  • sudo apt install crossbuild-essential-arm64
• On the terminal, run scripts/do-qemuarm -6 and that should compile LK and start qemu and boot to prompt.
  • Run help on prompt to check if its working
• Ctrl A + X to quit QEMU
