    Phoronix: Linux 4.18 Continues Onboarding Centaur x86 CPUs

    As reported a few months ago, the new Chinese x86 CPU venture formed between the government of Shanghai and VIA has been working on Linux support for these new x86 CPUs and that onboarding has continued with Linux 4.18...

    Thanks for the infos. I guess the Chinese government is capable of financing this and also interested in a less US-dependent CPU maker.

    Well, this image looks like a roadmap, but a roadmap alone doesn't make a high performance CPU. And VIA was mainly in the low power but rather efficient area when they were active, but I haven't seen much output from their side lately (for more than 5 years now?). So they will need some time to catch up.
    On the other hand, that may not be most relevant to the Chinese funders, as long as they get their design which is for them probably trusted / backdoor-free.

    Well it will be interesting to see if and what will develop there. Entry in the x86 market was long deemed impossible, but maybe with Chinese governmental funding and ... relaxed interpretation of the patent minefield... it could be possible.

    Yes and no. Zhaoxin is responsible for the development of new microarchitectures based on Centaur IP and they use their own codenames.

    However, their processors still appear as "CentaurHauls" (Processor ID):
    - ZX-C/ZX-C+ (codename "Zhangiang") = CentaurHauls Family 6 Model 15 Stepping 14
    - ZX-D (codename "WuDaoKou") = CentaurHauls Family 6 Model 31 Stepping 12

    Zhaoxin ZX-D, codename "WuDaoKou" (KaiXian KX-5000 and KaisHeng KH-20000) is a full SoC with an integrated memory controller, north bridge and graphics processor (Chrome 860 AKA C-860 iGPU, based on S3G IP).

    It can be said that this is a similar solution to Intel Sandy Bridge+ CPU or AMD APU.

    Zhaoxin processors are not available on the consumer market at all, even in China. Their clients are party and government agencies and state enterprises and institutions. However, they are considering entering the consumer market in the future.

    National security and technological independence have the highest priority here.
    However, achieving the Ryzen (1st gen) performance level in ZX-F (KX-7000/KH-40000) is not impossible.

    There are some rumors on the Anandtech forum, but I'm not sure if they are reliable.

    While they are at it, contributing code to the kernel, they might as well give Kevin Brace and handful of support.
