A POSIX-like x86-64 kernel and userspace written in Crystal. A CPU with x64 support is required to run the OS. The Makefile provides a script that will run QEMU on the kernel. To run with storage, an MBR-formatted hard drive image with a FAT16 partition must be provided in the running directory with the name drive.img. The kernel will automatically boot the main.bin executable on the hard drive, or panic if it can't be loaded.
Features
- Basic x86-64 support
- Hybrid conservative-precise incremental garbage collector
- IDE/ATA support (well, it can only load from primary master)
- Unix syscalls (open, read, write, spawn,...)
- A window manager and some graphical programs (terminal emulator, file manager)
- Userspace C library written in Crystal (mostly)
- Preemptive multitasking!
