As KVM supports passing Adjunct Processor (AP) crypto devices to
guests, we should make sure that the interface works as expected.
Three instructions provide the interface to the AP devices:
- nqap: Enqueues a crypto request
- dqap: Dequeues a crypto request
- pqap: Provides information and processes support functions
nqap & dqap work on crypto requests for which we currently don't want
to add tests due to their sheer complexity.
Which leaves us with pqap which is partly emulated for a guest 2 and
hence is a prime target for testing.
v2:
- Re-worked the ap_check() function to test for stfle 12 since
we rely on PQAP QCI in the library functions
- Re-worked APQN management
- Fixed faulty loop variable initializers in ap.c
- Fixed report messages
- Extended clobber lists
- Extended length bit checks for nqap
- Now using ARRAY_SIZE where applicabale
- NIB is now allocated as IO memory
