About

Behind every application software, there is an operating system. It is responsible for providing the applications with safe access to the computer hardware, and for implementing standard interfaces and abstractions such as files, windows, or processes. This course provides opportunity to learn about the operating system internals through standard lectures and practical assignments, where the students implement their own working operating system kernel.

Assignments

All assignment deadlines are in AoE. The deadlines for lecture quizzes are always Thursday noon local time.

MIPS Cross Compiler Toolchain

The cross-compiler toolchain (and MSIM too) is available in the Rotunda lab.

If you want to develop on your own machine, we recommend to use the precompiled packages for Fedora that are available via COPR.

dnf copr enable d3s/teaching
dnf install mff-nswi004-binutils-mipsel-linux-gnu mff-nswi004-gcc-mipsel-linux-gnu
dnf install mff-nswi004-gdb-mipsel-linux-gnu

For other distributions, we offer only a shell scripts to build the whole toolchain from scratch:

We do not support Windows: if you want to develop in Windows, we recommend to install Fedora in VirtualBox and use file-sharing and PuTTy to compile in the VM but develop on Windows.

Note that GitLab runners that run tests on your solutions use Docker images based on Fedora with the following packages.

You can also compile/run your code inside Docker/Podman, using the same environment as in GitLab CI. If the following command is executed from your clone of a00, it runs both the basic and extended tests. Note that it mounts the current directory in read-write mode and thus object files and executables are stored alongside your source files.

podman run \
    --rm \
    --memory=256m --memory-swap=512m \
    --mount=type=bind,src=.,destination=/root/nswi004,ro=false,bind-propagation=shared \
    mffd3s/nswi004-base:latest \
    /bin/bash -c 'cd /root/nswi004; make distclean; make && make check check2'

MSIM MIPS R4000 Simulator

If you want to run MSIM on Windows or on other platform, you need to compile it from sources.
