LudOS

LudOS is a hobby linux-like kernel written for fun in C++.

Features

  • Currently supports the 32-bit x86 architecture
  • An extensible virtual file system with the ability to expose function call interfaces on nodes to provide a cleaner interface than ioctl
  • PS/2 Keyboard and Mouse support
  • Preemptive and Cooperative Multitasking
  • Supports resolutions up to 1920x1080 using VBE framebuffer
  • Uses MTRRs to provide better performance with the framebuffer
  • Support for SATA drives via AHCI and ATA
  • ext2 filesystem and tar files mounting on the VFS
  • A lighting-fast graphical framebuffer terminal and shell

Goals

  • Support for the 64-bit x86 architecture and ARM
  • TCP/IP driver
  • A full-fledged graphical window manager
  • Dynamic linker support
  • Porting programs like GCC, NASM or FreeDoom to LudOS

Dependancies

QEMU is needed to run the kernel using tools/run.sh. On Ubuntu and derivatives : sudo apt-get install qemu-system

How to build :

Built binaries are already included in the build/bin directory, but if you want to build yourself the repository do as follow :

  • First build your own cross-compiler following these instructions : https://wiki.osdev.org/GCC_Cross-Compiler
  • Build to project by running CXX=<cross-g++-path> CC=<cross-gcc-path> cmake CMakeLists.txt and then make.

How to run :

Run the script tools/run.sh which will run QEMU on the kernel binary file.
