ZXFoundation™ is a DGP (Domain/Gate/Portal) experimental kernel that exclusively targets z/Architecture. A completely different design, no POSIX-compliance planned, isolated architecture, deeply integrated with z/Architecture specifics. Then project serves primarily as a PoC, and is intended for research and educational purposes. It aims to be a performant kernel that offers high stability for mainframes. And moreover a (working) proof that z/Architecture is a facinating world, not just tied to big corps and IBM themselves. Written completely in modern C++23 modules. It also implements its own IPL loader, ZXFoundationLoader™-a highly capable loader with many assistance and can be used in a kernel barebones if you are interested in the architecture.

Thank you! hope you enjoy

Hi friend, could you give me a little more information about this kernel? By the way, I'm also writing an operating system kernel called Valiantcore. If you want to take a look at its code, you can find it at https://gitHub.com/finndev62/valiantcore/. I released it for free under the GPLv2 license
