With this patchset, I can boot a kernel compiled for z14 (requiring
Miscellaneous-Instruction-Extensions Facility 2) (using -cpu max).
I am currently working on "vector-enhancements facility 1", I have most
stuff in place except:
- VECTOR FP (MAXIMUM|MINIMUM): needs some manual work to cover all types of
comparisons.
Once we have that in place, we can convert the QEMU machine to a
stripped-down z14.
v1 -> v2:
- "s390x/cpu_model: S390_FEAT_MISC_INSTRUCTION_EXT ->
S390_FEAT_MISC_INSTRUCTION_EXT2"
-- Added
- "s390x/tcg: Implement BRANCH INDIRECT ON CONDITION (BIC)"
-- Use new helper instead
- "s390x/tcg: Implement MULTIPLY SINGLE (MSC, MSGC, MSGRKC, MSRKC)"
-- Tune comparisons in CC computation
