中文摘要: RISC-V指令集架构的诞生促进了RISC-V硬件平台的快速发展, 因此, 在RISC-V架构硬件平台上运行高效且易于使用的操作系统需求日益增加. 面向分布式、开源开放的智能终端操作系统OpenHarmony技术正在不断演进, 其生态持续繁荣. 然而, 将OpenHarmony适配到RISC-V指令集架构平台上面临新的挑战, 包括软件栈和芯片移植的问题. RISC-V指令集架构平台的软件栈和芯片移植存在新的挑战. 本文提出了基于RISC-V QEMU平台的OpenHarmony标准系统移植的思路和方法, 通过对关键软件栈进行适配和在QEMU RISC-V虚拟化硬件平台上移植图形显示驱动, 成功实现了OpenHarmony标准系统在QEMU RISC-V虚拟化硬件平台上的正常启动, 并进入系统桌面. 该成果为开发者提供了在RISC-V平台上测试应用OpenHarmony标准系统的平台, 并为新的RISC-V硬件平台上移植OpenHarmony标准系统提供了参考.

Abstract:RISC-V instruction set architecture (ISA) has promoted the rapid development of the RISC-V hardware platforms, leading to growing demands for efficient and easy-to-use operating systems running on RISC-V architecture. As a distributed open-source mobile operating system, OpenHarmony continues to evolve with constant prosperous ecology. However, adapting OpenHarmony to RISC-V ISA platforms poses new challenges, including software stack and chip porting. This study presents an approach and methodology for porting the OpenHarmony standard system to the RISC-V QEMU platform. Based on adapting critical software stack components and porting the graphics display driver on the QEMU RISC-V virtualization hardware platform, the OpenHarmony standard system successfully starts on the QEMU RISC-V virtualization hardware platform and enters the system desktop. This achievement provides developers with a platform to test and apply the OpenHarmony standard system on RISC-V platforms and serves as a reference for porting the OpenHarmony standard system to new RISC-V hardware platforms.
