This is the final part of vector instruction support for s390x. It is based
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.
