# BeeOS

A simple and minimal "Unix-like" kernel trying to be POSIX compliant.

The kernel is **NOT STABLE** and is a discontinuous work mainly used as a didactical

tool for operating systems and low level programming.

Because of it's simplicity it can be used as a trampoline to start digging with

common operating system problems. Once you've mastered the BeeOS sources it will

be a lot easier to start hacking with more complex OS projects.

## Building

### Prerequisites

- gcc

- binutils

- make

- qemu (qemu-system)

### Quickstart

1. `make all`

    This command will build the kernel, standard library (libc), user utility

    library (libu) and user applications.

2. `(cd misc && sudo ./mkfs.sh)`

    Creates the root filesystem ramdisk with the user applications.

3. `(cd misc && ./qemu.sh)`

    Starts qemu and BeeOS.

## Implemented Milestones

  

**Supported Architectures**

- x86

**Core**

- Multitasking

- Syscalls

- Virtual Memory

- Virtual File System: ext2, devfs

- SLAB  allocator

- Buddy allocator

- Timer queues

**IPC**

- Signals

- Pipes

    

**Synchronization**

- Spinlocks

- Wait queues

**Drivers**

- TTY

- Screen

- Ramdisk

- Keyboard

- PRNG

**Other**

- Multi TTY console
