In early 2026, the openEuler community, together with the Institute of Software, Chinese Academy of Sciences (ISCAS) and industry partners, released the openEuler 24.03 LTS SP3 for RISC-V server bring-up. The release aligns with ongoing RISC-V Server Platform efforts and adds practical support for RVA23-related vector and virtualization features across toolchains, user-space components, and the kernel. A central part of this work is RVCK (RISC-V Common Kernel), a shared kernel baseline designed to reduce duplicated per-vendor enablement work and improve reuse across platforms. This talk presents the engineering lessons behind that effort, including cross-vendor coordination, upstream collaboration, and the challenges of building a reusable software baseline for server-class RISC-V systems.
