Ghost is an operating system for the Intel x86 platform written from scratch in C++ and assembly. It aspires to follow a pure micro kernel design and do stuff as clean as possible. Some of the important features are:

• multiprocessor & multithreading support
• window server, GUI with homemade toolkit
• patched GCC, OS specific toolchain
• custom libc implementation
• libstdc++ port
• extensive kernel API library (libapi)
• userspace C++ library (libuser)
• PS/2 keyboard & mouse driver, VESA video driver
• userspace filesystem driver support
• ELF binary support
• ipc mechanisms: pipes, signals, messages, shared memory
• named processes
• serial COM1 kernel logging
• virtual 8086 for BIOS calls

This is the bleeding edge source version of Octobre 26, 2015. Version 0.5.0

• major kernel update
  • new scheduler implementation with waiting/running queues
  • internal interface of syscall handlers has changed
  • task state is stored on handler entry
  • clean-ups and fixes
• new, cleaned up window server implementation
• example filesystem driver updated
• PS/2 driver toggleable for IRQ or polling mode
• interface for process configuration (tasks now know their executable source path)
• new utils "lines" and "read"
• tests cleaned up
• read-directory fixed

TODO:

• bugfix: window server occasionally hangs up on command receival

• applications sources for the essential system applications
• documentation about kernel concepts and features
• kernel sources of the kernel
• libapi sources of the userspace API library
• libc sources of the Ghost C library implementation
• libuser sources of the C++ userspace library
• patches patches & instructions for ports and toolchain setup
• tools set of tools that are used for development

There is an additional repository, the ghost-sysroot that is used as the base for the filesystem image for a blank installation.

See the patches/toolchain/TOOLCHAIN.md for instructions on how to set up the toolchain.
