Toy Operating System
This project was inteded as a playground for me to study operating system design by implementing the basics of a kernel for the x86 platform.
Development environment
The implementation requires a debian-based host machine. It can either be a native machine or virtual one. The tools/prerequisites are the standard one:
- git/gitk - for source control
- gcc/nasm - for compilation/linking
- make
- gdb - for debugging
- qemu - for device emulation
GDB
GDB is a powerfull debugger that integrates well with simulators. It's drawback is the lack of a powerful interface that would ease debugging. The variant that I am testing right now is a better command line interface. It does not need additional add-ons and is implemented through the use of a .gdbinit file. It can be downloaded from https://github.com/cyrus-and/gdb-dashboard.git. A variant has been included in the tools directory. To use it just copy it in the home directory.
