Project #1: Hello world, xv6

xv6 is an instructional operating system developed by MIT based on Ken Thompson and Dennis Ritchie’s Unix version 6 (v6). In this course, we will use xv6-riscv, a version recently ported to a multi-core RISC-V machine. The goal of this project is to set up your development environment on Linux or macOS and familiarize yourself with our project submission server.

• Project specification available here
• Due date: 11:59 PM, March 17 (Tuesday).
