Zion Microkernel

The Zion Microkernel is a capability based kernel. The types of objects that processes can hold a capability to exist in the object/ directory. The system calls used to interact with them are enumerated in include/zcall.h and are implemented in the syscalls/ directory.

The system uses a barebones ELF loader (loader/init_loader.h) to jump to userspace but from there userspace processes are responsible for loading child processes into memory and executing them.

Open Work

The TODO file enumerates current areas for improvement.
