+ Select this option to enable driver support for IBM Coherent
+ Accelerators (CXL). CXL is otherwise known as Coherent Accelerator
+ Processor Interface (CAPI). CAPI allows accelerators in FPGAs to be
+ coherently attached to a CPU via an MMU. This driver enables
+ userspace programs to access these accelerators via /dev/cxl/afuM.N
+ devices.
+
+ CAPI adapters are found in POWER8 based systems.

+ If unsure, say N.
