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 complexity. Which leaves us with pqap which is partly emulated for a guest 2 and hence is a prime target for testing.
