Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens Wu Yanzu in South China for the delivery of clues! CTOnews.com August 14 news, in June this year, Linus incorporated most of the code of the Godson LoongArch CPU architecture into Linux 5.19, including the final system call interface and all core functions, which is considered to have completed the initial support.

The latest Linux 5.20 (or named Linux 6.0) commit request includes more support for the Loongson LoongArch architecture, such as PCI, stack remover and stack trace, optimizing getcpu () with vDSO, bug fixes, build bug fixes, and updates to its default kernel configuration file.

CTOnews.com learned that in 2020, based on 20 years of CPU development and ecological construction, Godson launched the Godson autonomous instruction system architecture LoongArch, which maintains compatibility with MIPS, X86 and ARM, and has 2000 proprietary instructions, including infrastructure and extension parts such as vector instruction, virtualization, binary translation, etc.

Previously, Linus, the father of Linux, said he planned to give up the 5.x series and change it to the Linux 6.0version number because the number of the small version was too large.

At present, Godson LoongArch architecture has been supported by GO language and GCC compiler. In addition, the SMBIOS specification has supported the Godson LoongArch architecture, and since then the basic hardware information developed based on the dragon architecture platform will be standardized and uniformly displayed, and the dragon architecture has become another independent CPU instruction system architecture supported by SMBIOS after x86, ARM, and RISC-V.
