RISCV-OLK6.6 Source-Compatible Version Guide

RISCV-OLK6.6 Source-Compatible Plan

Currently, the kernel versions maintained by various RISC-V SoC manufacturers are inconsistent, while the openEuler system requires a unified kernel version. This inconsistency results in various operating system versions based on different development boards having divergent third-party kernels, increasing maintenance difficulty and causing ecosystem fragmentation. The goal of the riscv-kernel project is to establish a unified kernel ecosystem for the RISC-V architecture in openEuler, sharing the benefits of Euler's ecosystem development and influence. This project is under development, and contributions from all parties are welcome.

The project is primarily developed on the OLK-6.6 branch at https://gitee.com/openeuler/riscv-kernel and will be further integrated into OLK's source and artifact repositories.

riscv-olk6.6

The project has nearly completed the source compatibility work for SG2042 and the basic source compatibility work for TH1520.
