original focus of innovating diversified computing architectures. On March 30, 2020, the Long Term Support (LTS) version openEuler 20.03 was officially released, which was a new Linux distribution with for All Scenarios openEuler supports multiple processor architectures (x86, ARM, RISC-V) and will support other brands (PowerPC, SW64) in the future, as part of a focus to continuously improve the ecosystem Contribution to the Linux Kernel As a major contributor to the Linux kernel, the kernel development team is responsible for enhancing the processor architectures, Advanced Configuration and Power Interface

was initiated for diversified computing architectures. On March 30, 2020, the first Long Term Support (LTS) version openEuler 20.03 was released, which was a new Linux distribution with independent inspection: strengthens protection against Return Oriented Programming (ROP) attacks. 15. ILP32 support: The Kunpeng 920 ARM64 environment supports 32-bit applications. 16. Memory System Resource Partitioning Enhanced ARM64 kdump: Memory reservation for addresses greater than 4 GB enables kdump to support machines with larger memory. 20. Raspberry PI: The openEuler 21.03 kernel natively supports the
