+         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.
