	  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.
