Question Regarding SystemZ Implementation Missing Instructions
...ve also done cursory searching, here's a random selection of 12 (out of
525) more instructions that I've confirmed aren't implemented:
- ALSI Add Logical with Signed Immediate
- BAKR Branch and Stack
- BAL Branch and Link
- BALR Branch and Link
- CEGR Convert from Fixed (SH <- 64)
- LFPC Load FPC
- MDR Multiply (LH)
- STCMY Store Characters under Mask (low)
- STMY Store Multiple (32)
- TAR Test Access
- VACCC Vector Add With Carry Compute Carry (NEW!)
- VFENE Vector Find Element Not Equal (NEW!)

[RFC/PATCH 00/15] kvm on big iron
This patch series introduces a backend for kvm to run on IBM System z
machines that uses the mainframe's sie virtualization capability. This
work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with
a 64bit linux host. Userspace will follow once we're done brushing it
over.
The patch queue consists of the following patches, which can be applied
in sequence on top of kvm.git
