One more hobby operating system

YayOS

Recorded from xterm. QEMU links stdin with COM1, that YayOS uses

What is this repo for?

YayOS is an operating system powered by YYSloth kernel.

What is the system capable of doing?

It is capable of running simple shell connected to a serial port. Shell can be used to run other applications on the ramdisk

What is the kernel capable of doing?

The API provided by the kernel is extremely simple. It is now fully described in the file YYSloth/README.md. Docs are coming in the future.

How directory structure works

YYSloth/ - everything related to the kernel (source, docs, binary...)

YYUserspace/ - source code of the user space applications. One folder is used for each application. For the application folder structure see YYUserspace/README.md

initrd - static data that needs to be located at the root of filesystem

grub - grub metadata

What are shell scripts doing?

build.sh - build the whole system

buildkernel.sh - only build kernel

builduserspace.sh - create ISO. Requires buildkernel.sh to be executed in advance

test.sh - run the kernel in qemu. There are multiply lines. You can uncomment one that you need.
