How Vivo’s Rust‑Based BlueOS Kernel Redefines Security and Performance

On July 23, the 2025 Open Atom Open‑Source Ecosystem Conference launched, gathering government, industry, academia, and research forces to discuss open‑source trends.

During the opening, Vivo’s Vice President Zhou Wei shared the company’s exploration of open‑source and intelligent operating systems, announcing that the BlueOS kernel is now officially open‑sourced.

BlueOS: A Rust‑Based Smart OS for the AGI Era

BlueOS is Vivo’s self‑developed intelligent OS designed for the general‑AI era. Its architecture deepens AI integration, supporting multiple algorithms and multimodal inputs for enhanced intelligence, while high‑performance techniques ensure smooth operation across computing, storage, and display.

Security is a core focus: industry data shows about 70% of OS vulnerabilities stem from improper memory use. To address this, Vivo built BlueOS entirely in Rust, leveraging compile‑time ownership, borrowing, and lifetime checks to guarantee memory safety and eliminate many classes of bugs.

BlueOS Kernel: Secure, Lightweight, General‑Purpose

The Rust‑written BlueOS kernel offers three key traits: security, lightweight, and generality. It is the first open‑source Rust kernel for embedded platforms and mobile devices, using Rust’s ownership system to ensure memory safety at compile time and smart pointers at runtime without extra garbage‑collection overhead. The minimal kernel footprint is only 13 KB of RAM.

It supports multiple architectures such as RISC‑V and ARM, and provides POSIX‑compatible libraries for ecosystem integration.

Core Kernel Capabilities

The kernel includes full system scheduling, memory management, file system, networking, and device driver support. Scheduling covers time‑slice round‑robin and priority‑based real‑time algorithms. Memory management combines Rust safety with various allocation strategies. The file system uses a hierarchical design with inode abstraction. Networking implements a basic TCP/IP stack with both blocking and non‑blocking modes and a zero‑copy design. Device management abstracts hardware, allowing Rust driver development and compatibility with existing C drivers.

Embracing Open Source for Domestic OS Growth

Vivo’s leadership expressed a commitment to contribute this high‑security kernel to the industry, collaborate openly, and advance foundational software. The company will continue partnering with the Open Atom Open‑Source Foundation to promote Rust in China and launch the third Vivo BlueOS Innovation Competition, fostering Rust talent.
