[kvm-unit-tests,0/5] s390x: STFLE nested interpretation

Message

Nina Schoetterl-Glausch Dec. 13, 2023, 12:49 p.m. UTC

Add a test case that tests the interpretation of STFLE performed by a
nested guest using a snippet.
Also add some functionality to lib/, namely:
* simple pseudo random number generation (arch independent)
* exit (optionally with return code) from snippet (s390x)

Nina Schoetterl-Glausch (5):
  lib: Add pseudo random functions
  s390x: lib: Remove double include
  s390x: Add library functions for exiting from snippet
  s390x: Use library functions for snippet exit
  s390x: Add test for STFLE interpretive execution (format-0)
