[kvm-unit-tests,v1,0/5] s390x: SCLP Unit test

Message

Claudio Imbrenda Oct. 22, 2019, 10:52 a.m. UTC

This patchset contains some minor cleanup, some preparatory work and
then the SCLP unit test itself.

The unit test checks the following:
    
    * Correctly ignoring instruction bits that should be ignored
    * Privileged instruction check
    * Check for addressing exceptions
    * Specification exceptions:
      - SCCB size less than 8
      - SCCB unaligned
      - SCCB overlaps prefix or lowcore
      - SCCB address higher than 2GB
    * Return codes for
      - Invalid command
      - SCCB too short (but at least 8)
      - SCCB page boundary violation
