[Xen-devel] [PATCH v2 0/6] x86emul: fixes, improvements, and beginnings of AVX512 support

["Jan Beulich" <JBeulich@xxxxxxxx>]

1: fix FMA scalar operand sizes
2: extend MASKMOV{Q,DQU} tests
3: support AVX512 opmask insns
4: clean up AVX2 insn use in test harness
5: correct EVEX decoding
6: generalize vector length handling for AVX512/EVEX

While I also have ready a patch emulating the basic AVX512 moves,
its prereq to widen respective fields in HVM code to allow for 64 byte
operand sizes has a dependency on the "x86/HVM: implement memory
read caching" series, which looks to be stalled, and I prefer to avoid
posting further patches with dependencies on stalled series.

Some support beyond moves is also mostly ready, but it's not quite
enough yet to enable testing that code in the harness, and I'd rather
not post code that I haven't pushed through the harness yet. The
partial testing I've been doing means, however, that in particular the
last two patches here have been tested already, even if no such
testing would be possible for others until further patches actually get
posted.

Jan
