It is bas= ed on part 2, which is will send a pull-request for to Conny soon. Part 1: Vector Support Instructions Part 2: Vector Integer Instructions Part 3: Vector String Instructions Part 4: Vector Floating-Point Instructions The current state can be found at (kept updated): https://github.com/davidhildenbrand/qemu/tree/vx It is based on: - [PATCH v2 0/5] s390x/tcg: Vector Instruction Support Part 3 - [PATCH v1 0/2] s390x: Fix vector register alignment With the current state I can boot Linux kernel + user space compiled with SIMD support. This allows to boot distributions compiled exclusively for z13, requiring SIMD support. Also, it is now possible to build a complete kernel using rpmbuild as quite some issues have been sorted out. While the current state works fine for me with RHEL 8, I am experiencing some issues with newer userspace versions (I suspect glibc). I'll have to look into the details first - could be a BUG in !vector instruction or a BUG in a vector instruction that was until now unused. In this part, all Vector Floating-Point Instructions introduced with the "Vector Facility" are added. Also, the "qemu" model is changed to a z13 machine.
