Wingos

WingOS is a small hobbyist 64 bit kernel made with <3 in C++

latest milestone - blog - old branch

What the project is about

The project is about creating an operating system that is easy to program for, with a simple and clean API.

• It tries to experiment with new ideas and API, ditching old and legacy concepts when possible.
• WingOS is a microkernel based operating system, currently targetting x86_64. It tries to be a capability based OS, with a focus on security and stability.
• The userspace is beginning to be fleshed out, with a VFS+ext4+nvme support.

Feature list

For now the kernel is still in development, but it has a few key features:

• is 64 bit
• is SMP capable (multiple CPU support)
• has a basic scheduler with SMP support, priority, and CPU affinity support (and support cpu tree for NUMA systems)
• Nvme (NVMe) disk support (in userspace)
• Ext4 filesystem support (in userspace)
• VFS support (in userspace)

Dependencies

• The project uses the cutekit build system.
• The project uses limine as a bootloader.

Roadmap (OS)

• Boot
• x86 basic support (interrupt, paging, ...)
• SMP support (apic, ...)
• Scheduler (with SMP support, priority, and cpu affinity support)
• Loading user space app
• User space (ring 3)
• Syscalls
• Spaces and handles
• Userspace objects (Virtual and Physical Memory, IPC, Task...)
• Services and IPC (inter process communication)
• PCI support (scan, devices, ...) (in userspace)
• Hello File! (NVME + GPT + Ext4 + VFS)
• Blocking IPC
• Graphics support (VESA, framebuffer, ...)
• Input support (keyboard, mouse, ...)
  • Interrupt handling in userspace
• Port DOOM
• Signals
• Create a shell
• Above and beyond

Roadmap (UI)

• Basic Render
• Render fill
• Render text
• Transform
• Shader

Building the project

For now I don't have a complete dependency list, but you will need:

• cutekit
• Clang cross compiler for x86_64
• Everything needed to build a cross compiler

Run bash meta/build/make_cross_compiler.sh to build the Wingos specific version of gcc.

Now do ck s to start the build and run.

Do ck p to build ports (now no ports are buildable, do a git clone recursive to get all ports).

Made by human

WingOS is made by Humans, and not by a generative AI.
