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 August 28, 2015.
- Idle task uses "HLT" to prevent 100% processor usage
- stdio is fixed, piping works
- Directory reading functionality is reworked
- Spawner and others uses variable messages
- Color in the terminal, and a fancy start screen
- Minor bugfixes here and there
g_atomic_waitis nowg_atomic_lockg_spawnhas slightly changed, its now possible to specify in and out descriptors of a process when spawning it
TODOs:
- Directory reading causes crashes
- Removing the old recv_msg/send_msg interface
- Milestone: window server rewrite

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.
