A POSIX-like x86-64 kernel and userspace written in Crystal. Building See BUILDING.md . Running A CPU with x64 support is required to run the OS. The Makefile provides a script which will run QEMU on the kernel: make run 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. Issue this command to run with gdb attached: make rungdb_img Features Basic x86-64 support Hybrid conservative-precise incremental garbage collector IDE/ATA support (well, it can only load from primary master) FAT16 support Unix syscalls (open, read, write, spawn,...) Preemptive multitasking! Userspace C library written in Crystal (mostly) A window manager and some graphical programs (terminal emulator, file manager) And much more as I go...
