A long time ago, in the &os; 5 times, there was an initial + port of &os; to s390 (32bit) and s390x (64bit) + which booted past init on good days in an emulator.

+ +

As an attempt to revive the s390x/systemz efforts I started + to get &os; s390x to build with clang/llvm 3.90. + At this time it is possible to build world and a GENERIC kernel + skeleton (not doing anything yet) using external binutils.

+ +

The primary idea of this initial work was to allow to + incrementally add the neccessary architecture-specific code. + Having the build framework done will allow third-party + developers to simply type make, as they are willing + to contribute to the port without having to know &os; build + specifics. After some cleanup and further updates to a more + recent HEAD I am planning to push the current work to a public + repo to allow collaboration.

+ + + + Write a wiki page with per-architecture specific tasks + that need to be done based on the current work and the experience + from arm64 and riscv. + + Implement both the user space and kernel per-architecture + gaps. + + Figure out a way to get access to IBM's zPDT or better + emulators to ease implementation, testing, and debugging. + +
