CeanOS

CeanOS is a UNIX-like operating system . The goal is to create a lightweight, efficient OS with a non-bloated kernel and a user-friendly interface. This project is built with C and assembly using no standard libraries .

warning -> i took rc versioning instead of alpha and beta because it sounds more professional and cooler

Kernel Status

The CeanOS kernel is a monolithic x86 one. I am also planning to port it to x86_64 and arm after im done with x86 .

Userland Status

There is no userland yet lol.

Other Information

The file vga_types.h includes macros from the Linux source code. You can find the original file here.

The files ata.c and ata.h are taken from this location(malwarepad/cavOS) with some modifications to integrate into CeanOS .

Goals

Here’s what I’m working on:

Kernel

• Basic kernel initialization
• Simple memory management (GDT, IDT, ISRs)
• Advanced memory management (paging, virtual memory, heap)
• Multitasking and process scheduling
• Inter-process communication (IPC)
• Dynamic module loading/unloading

Architecture

• x86 (Work in Progress)
• x86_64 (planned)
• ARM (planned)

Filesystems

• FAT32 boot sector support
• FAT32 read/write operations
• ext2 read/write operations
• Advanced filesystem features (journaling, metadata management)
• VFS
• tmpfs

Device Drivers

• Input/Output:
  • Keyboard
  • Mouse
  • USB devices
• Graphics:
  • VGA text mode
  • Framebuffer
  • GPU acceleration
  • CWM (Cean Window Manager)
• Storage:
  • Basic ATA/IDE driver
  • AHCI driver
  • SSD/HDD/USB device support
• Networking:
  • Basic NIC driver
  • TCP/IP stack implementation
  • DHCP and DNS support
  • HTTP support
• Power Management:
  • ACPI implementation
  • Power states (sleep, hibernate)
  • Battery management for portable devices
• Other:
  • PCI (work in progress)

Userland

• Minimal shell (interactive terminal)
• Core utilities
• Package manager (eventually)
• Multitasking user applications
• System services (e.g., logging, daemon management)

Networking

• Packet handling
• Basic firewall support
• DNS resolution
• HTTP/HTTPS client
• SSH support (long-term)

Security

• User authentication system
• Multi-user environment support
• Permissions and access control
• Encrypted filesystem support
• Kernel-level security features (ASLR, DEP)

Graphics

• VGA text mode (for kernel debugging)
• Framebuffer driver
• Basic GUI support
• cwm (Cean Window Manager)
• Theme and UI customization options

System Utilities

• Logging system (syslog)
• Debugger for kernel and userland
• Performance monitoring tools (CPU, memory usage)
• Disk partitioning and formatting tools

Development Tools

• In-system compiler for C (eventually)
• Debugging tools for applications and kernel
• Cross-compilation support

Long-Term Vision

• Support for virtualized environments
• Distributed computing capabilities
• Experimental features
• Self-hosting

Compiling
