[kvm-unit-tests PATCH v1 0/5] s390x: IPM/SPM and MSA tests

[David Hildenbrand <david@redhat.com>]

Developed while working on:
https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg05133.html

Only the basics for MSA instructions are tested (basically everything QEMU
also implements), but no real en/decryption.

All tests seem to pass under KVM.

For TCG, only the usual low address protection tests fail.
To run under TCG, the feature have to be enabled explicitly for now:

./s390x-run s390x/emulator.elf \
     -cpu qemu,msa-base=on,msa3-base=on,msa4-base=on,msa5-base=on,stfle=on


David Hildenbrand (5):
  s390x: add a test case for the ipm + spm instructions
  s390x: add cpacf.h from Linux
  s390x: make sure cpacf.h can be used
  s390x: query and store STFL(E) facilitites
  s390x: test for various MSA instructions
