The Design and Building of openKylin on RISC-V Architecture

The RISC-V instruction set architecture (ISA) stimulates the expeditious development of novel hardware platforms. Consequently, the need for an efficient and easy-to-use operating system on RISC-V architecture emerges. However, new challenges such as system building, hardware adaptation, and application ecosystem should be addressed as the hardware podium develops. This article explores the design and building of openKylin, an open-source operating system, on the RISC-V hardware platform to address these issues, including kernel optimization, UKUI (Ultimate Kylin User Interface) package compilation, and application compatibility. The test results show that the x86 benchmark can run in the openKylin operating system correctly and efficiently on the RISC-V platform.
