[kvm-unit-tests,v1,0/8] s390x: Extend instruction interception tests

Message

Nico Boehr Jan. 21, 2022, 3:09 p.m. UTC

This series extends the instruction interception tests for s390x.

For most instructions, there is already coverage in existing tests, but they are
not covering some failure cases, e.g. bad alignment. In this case, the existing
tests were extended.

SCK was not under test anywhere yet, hence a new test file was added.

The EPSW test gets it's own file, too, because it requires a I/O device, more
details in the respective commit. 

The EPSW test must be fenced when running in non-QEMU. For this, we need
vm_is_kvm() from Pierre's patchset
