I built a baremetal RustOS (O(1)allocator NVMeDMA ZeroTrust sandbox for AIAgents

PolymorphOS is a fully custom bare-metal Rust kernel designed as a secure, zero-trust sandbox for AI agents. It features an O(1) memory allocator, a custom NVMe driver with DMA, a 3D Gaussian splat UI, and lock-free async execution, booting in 300ms.

Key points

  • PolymorphOS boots in 300ms and is a #![no_std] bare-metal kernel built from scratch in Rust.
  • MICT Elastic Memory Allocator provides deterministic O(1) allocation, avoiding latency spikes.
  • Custom PCIe NVMe driver with zero dependencies performs DMA directly to flash controller.
  • 3D Gaussian splat UI replaces traditional window manager for tear-free rendering.
