[Qemu-devel] [PATCH v3 0/3] Implement basic MSA functions

[David Hildenbrand]

Some leftover from "target/s390x: tcg improvments + MSA functions".

Implement all basic MSA (cpacf/crypto) instructions <= z13. Only provide
the query subfunction (to query available subfunctions), no actual
de/encryption yet. Good enough to unlock the STFL bits.

I have written kvm-unit-tests for MSA functions and for SPM/IPM. Will
send them out soon. I use the following cpu model to test with an upstream
kernel compiled for z10:

... -cpu qemu,mvcos=on,stfle=on,ldisp=on,ldisphp=on,\
              eimm=on,stckf=on,csst=on,csst2=on,ginste=on,\
              exrl=on,msa-base=on,msa3-base=on,msa4-base=on,msa5-base=on ...

v2 -> v3:
 - "s390x/tcg: add basic MSA features"
 -- drop one check (fc >= 128) that can due to masking never happen

v1 -> v2:
 - "s390x/tcg: implement spm (SET PROGRAM MASK)"
 -- use tcg_gen_extrl_i64_i32 + tcg_gen_extract_i32
 - "s390x/tcg: move wrap_address() to internal.h"
 -- internal.h instead of cpu.h
 - "s390x/tcg: add basic MSA features"
 -- minor style fixes
