CSE 536: Advanced Operating System

Follow steps to setup necessary dependencies for developing xv6 OS. Find the respective implentations in the branches of the same repository.

Check the following branches to find their respective implementations

• 1_startup_process - Boot Rom and Bootloader
• 2_vitual_mem_mngt - Process Memory Management
• 3_user_thread_mngt - User-Level Thread Management
• 4_trap_emulate_virtualization - Trap and Emulate Virtualization

A. Installing xv6 pre-requisites

Please reach out to the TAs if you have any installation issues.

Linux/WSL

1. Navigate to the install/linux-wsl folder
2. Install RISC-V QEMU: ./linux-qemu.sh
3. Install RISC-V toolchain:./linux-toolchain.sh
4. Add installed binaries to path: source .add-linux-paths

MacOS

1. Navigate to the install/mac folder
2. Install RISC-V QEMU: ./mac-qemu.sh
3. Install RISC-V toolchain: ./mac-toolchain.sh
4. Add installed binaries to path: source .add-mac-paths

B. Running the xv6 OS

1. Navigate back to main folder and clone the xv6 OS using

    git clone https://github.com/mit-pdos/xv6-riscv.git
   

2. Navigate to xv6-riscv and run make qemu

C. FAQs

1. While running linux-qemu.sh, if you run into ERROR: glib-2.48 gthread-2.0 is required to compile QEMU, then :

• Run this command in the terminal. sudo apt install libglib2.0-dev. This is caused due to a newer version of your linux distro(link).

2. linux-qemu.sh : ../meson.build:328:2: ERROR: Dependency "pixman-1" not found, tried pkgconfig

• Can be resolved by running sudo apt install libpixman-1-dev (link)

Acknowledgement

Thankful to the xv6 team at MIT for their open-source codebase.
