Select this option if you want to enable support for
s390 cryptographic adapters like:
- + PCI-X Cryptographic Coprocessor (PCIXCC)
- + Crypto Express 2,3,4 or 5 Coprocessor (CEXxC)
- + Crypto Express 2,3,4 or 5 Accelerator (CEXxA)
- + Crypto Express 4 or 5 EP11 Coprocessor (CEXxP)
+ + Crypto Express 2 up to 7 Coprocessor (CEXxC)
+ + Crypto Express 2 up to 7 Accelerator (CEXxA)
+ + Crypto Express 4 up to 7 EP11 Coprocessor (CEXxP)
+
+config ZCRYPT_DEBUG
+ bool "Enable debug features for s390 cryptographic adapters"
+ default n
+ depends on DEBUG_KERNEL
+ depends on ZCRYPT
+ help
+ Say 'Y' here to enable some additional debug features on the
+ s390 cryptographic adapters driver.
+
+ There will be some more sysfs attributes displayed for ap cards
+ and queues and some flags on crypto requests are interpreted as
+ debugging messages to force error injection.
+
+ Do not enable on production level kernel build.
+
+ If unsure, say N.
