| 	  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.
