s390x: add test for SIGP STORE_ADTL_STATUS order
Add a test for SIGP STORE_ADDITIONAL_STATUS order.
There are several cases to cover:
- when neither vector nor guarded-storage facility is available
s390x: add test for SIGP STORE_ADTL_STATUS order
Add a test for SIGP STORE_ADDITIONAL_STATUS order.
There are several cases to cover:
- when neither vector nor guarded-storage facility is available, check
the order is rejected.
- when one of the facilities is there, test the order is rejected and
adtl_status is not touched when the target CPU is running or when an
invalid CPU address is specified. Also check the order is rejected
in case of invalid alignment.
- when the vector facility is there, write some data to the CPU's
vector registers and check we get the right contents.
- when the guarded-storage facility is there, populate the CPU's
guarded-storage registers with some data and again check we get the
right contents.
To make sure we cover all these cases, adjust unittests.cfg to run the
test with both guarded-storage and vector facility off and on. In TCG, we don't
have guarded-storage support, so we just run with vector facility off and on.
