SexOS · Strategic Planning

Roadmap to Daily Driver

The strategic progression from microkernel architectural prototype to production-ready, AI-native, high-performance operating system.

🏁 Completed Milestones

Step 1: "Hello World" Userland — COMPLETE ✅
  • PMM: Robust BitmapFrameAllocator for physical memory recycling.
  • Paging: Dynamic 64-bit Single Address Space (SASOS) management.
  • Binary Execution: Real ELF64 loader mapping segments into memory.
  • Privilege Levels: Ring 3 support via GDT expansion and iretq context switching.
  • Scheduling: Preemptive APIC-timer-driven round-robin scheduler with Wait Queues.
Step 2: Basic I/O and Storage — COMPLETE ✅
  • Hardware Discovery: Functional PCI/PCIe enumeration engine.
  • Storage Drivers: Real PIO-based IDE/ATA driver.
  • Filesystems: Functional FAT32 and Ext2 parsing (BPB and Inode logic).
  • VFS: Client-Side Path Resolution (CSPR) and Hurd-style active translators.
Step 3: Interactive Shell & Libc — COMPLETE ✅
  • Drivers: Real PS/2 keyboard/mouse scancode decoding in sexinput wired to TTY.
  • Libc: relibc (Rust-native) ported to SexOS sexc PDX interface with real file ops.
  • CoreUtils: Mature sexc bridge unblocks GNU bash, ls, cat, and grep.
  • Milestone: Boot into a blinking cursor, type ls, and see files on a real physical disk.

🚀 Current & Future Milestones

Step 4: Networking & Display — IN PROGRESS 🏗️
  • Driver: Real Intel e1000 Gigabit driver with DMA ring initialization.
  • Network Stack: Asynchronous Zero-Copy sexnet stack (sDDF model) with ARP and IPv4 logic.
  • Graphics: sexdrm with real VESA/GOP framebuffer mapping and GEM buffer management.
  • Milestone: The system can ping an IP address and render high-resolution 32bpp graphics.
Step 5: The Desktop Environment — PLANNED 📅
  • Inter-Domain SHM: Implement mmap shared memory for zero-copy pixel transfer between App and Compositor.
  • Wayland Lifting: Use sex-lift-ai to port a Wayland compositor and the Mesa library.
  • Input Translation: Connect sexinput event rings to the Wayland server.
  • Milestone: A graphical desktop with a functional terminal emulator and window management.
Step 6: Self-Hosting & Ecosystem — PLANNED 📅
  • Toolchain: Port rustc and gcc to the sexc layer.
  • Package Management: Full-scale deployment of the Sex-Store graphical manager.
  • Mass Driver Lifting: Achieve hardware parity via the sex-lift-ai pipeline.
  • Apps: Native ports of modern browser engines, text editors, and Git.
  • Milestone: DAILY DRIVER. Use SexOS to write, compile, and commit the next version of SexOS.

💎 The "SexOS Advantage"

AdvantageMechanism
1. AI-Native BootstrappingGemini AI embedded in early-boot shell for hardware discovery and driver lifting.
2. SASOS PerformanceSingle Address Space eliminates page table swapping overhead during IPC.
3. sDDF Zero-CopyHigh-throughput storage and networking via lock-free descriptor rings.
4. Hardware-Enforced IsolationIntel PKU ensures zero-cost context switching between drivers and apps.
5. Runit-Style StabilityMinimalist, dependency-aware service management with automated reincarnation.
