Core Viewpoint - The article discusses vivo's development of the Blue River operating system, emphasizing its transition from self-research to open-source, and the use of Rust programming language to address the challenges posed by the AI era in operating systems [2][7][19]. Group 1: Operating System Evolution - The operating system has become a crucial bridge in the AI era, managing hardware resources and ensuring data security [4]. - Traditional operating systems, primarily built on C language, face structural limitations in adapting to modern demands for lightweight, secure, and cross-platform solutions [5][6]. - The emergence of Rust as a programming language aims to overcome the security vulnerabilities and inefficiencies of C/C++ in system-level programming [10][12]. Group 2: Blue River Operating System Features - The Blue River kernel, built using Rust, offers three core advantages: security, lightweight design, and universality [14]. - The kernel ensures memory safety and stability, requiring minimal hardware resources, with a memory footprint as low as 13KB [14]. - It supports various chip architectures, including RISC-V and ARM, and is compatible with POSIX interfaces, enhancing its adaptability across different platforms [14]. Group 3: Strategic Importance of Open Source - vivo's decision to open-source the Blue River kernel is aimed at fostering an ecosystem around Rust, enhancing its adoption and influence in the industry [20][21]. - The company is committed to building a developer community through initiatives like the Blue River operating system innovation competition, which has seen participation from over 400 teams from more than 90 top universities [21]. - This open-source strategy is part of vivo's broader vision to drive innovation in the operating system space and contribute to the development of the Rust programming language ecosystem in China [20][21].
