apoptOS

A modern x86_64 UNIX-like microkernel-based operating system written in C and Assembly






## Features

- Higher half kernel

- Limine bootloader

- Stivale2 boot protocol

- Serial communication

- GDT and TSS

- IDT and ISR's

- Physical memory management -> Bitmap based allocator & Slab allocator

- Virtual memory management -> 4-level paging support

- Heap memory -> `malloc` and `free`

- Basic kernel library

- ACPI table parsing

- LAPIC and IOAPIC

- LAPIC timer and HPET

- SMP

## Goals

- Understand:

  - Microkernels

  - UNIX-like systems

  - Scheduling

  - Messaging (IPC)

  - Syscalls

  - Userland

  - ELF

  - Filesystems

- Write:

  - Clean code

  - A [blog](https://tix3dev.github.io/apoptos-series-1), documenting learning process
