A Cross-Architecture Operating-System Kernel
OMEGA is a lightweight, high-performance Unix-like operating-system kernel actively developed by COS Q Network.
It cross-compiles natively for x86_64, AArch64, and RISC-V 64, with an explicit ABI boundary, native userspace entry paths, and a QEMU-based verification workflow.
OMEGA provides architecture-specific boot and privilege transitions while maintaining a shared kernel and userspace model. x86_64 boots through long mode, AArch64 transitions from EL2 to EL1, and RISC-V 64 starts in supervisor mode through OpenSBI.
The kernel includes physical and virtual memory managers, a dynamic heap, interrupt and trap handling, preemptive scheduling foundations, Linux-compatible syscall entry paths, and a native userspace bootstrap.
Its build system uses Clang, LLVM, ld.lld, and CMake toolchain integration without requiring external GCC cross-compiler dependencies.
OMEGA includes a bitmap physical memory manager, architecture-aware page tables, a dynamic kernel heap, virtual filesystems, initrd RAM disks, ELF64 executable loading, and per-process address spaces.
Native userspace paths support x86_64 Ring 3, AArch64 EL0, and RISC-V U-mode entry. The kernel provides Linux-compatible syscall conventions, process lifecycle primitives, copy-on-write validation, credentials, groups, ownership, mode checks, and umask foundations.
Hardware foundations include PCI scanning, VirtIO networking, keyboard and HID input, display backends, cross-architecture storage abstractions, and experimental VirtIO-Block support.
The repository includes QEMU launchers, bootable disk image generation, Docker and DevContainer support, GitHub Actions CI/CD, and automated multi-architecture test workflows.
The Omega Virtual Device manager provides an Android-like interface for creating and running x86_64, AArch64, and RISC-V profiles with storage, networking, initrd, snapshots, QMP state, and an integrated VNC viewer.
