With recent changes in the zcrypt device driver, the master key verifi- cation patterns of the AES master key of am APQN can be obtained by reading the sysfs attribute 'mkvps' of an APQN device of type CCA- Coprocessor. The sysfs attribute can be found under '/sys/devices/ap/cardnn/nn.mmmm/', where nn specifies the card number in hex, and mmmm specifies the domain number on hex.
