Subject: [PATCH v2 00/26] s390x/tcg: Implement Vector enhancements facility and switch to z14
Date: Mon, 17 May 2021 16:27:13 +0200 [thread overview]
Message-ID: <20210517142739.38597-1-david@redhat.com> (raw)
This series adds support for the "Vector enhancements facility" and bumps
the qemu CPU model to a stripped-down z14.
I tested most vector FP instructions by generating random instructions
and vectors, comparing the result with results on actual hardware. I did
not test instructions/instruction variants with (partial) undeterministic
behavior and exception handling.
Linux' also seems to boot/work fine with it. Howeever, while testing this
series I noticed that Linux checks for the wrong facility bit - see [1].
I tested by temporarily faking availability of the "wrong" facility bit.
[1] https://lkml.kernel.org/r/20210503121244.25232-1-david@redhat.com
v1 -> v2:
- Too much changed to spell it out explicitly. Mostly addressed feedback
from Richard, a couple of bugfixes found while testing, and some
simplifications/cleanups.
- Rebased on top of Richard's softfloat rework
