  16           Select this option to enable driver support for IBM Coherent
  17           Accelerators (CXL).  CXL is otherwise known as Coherent Accelerator
  18           Processor Interface (CAPI).  CAPI allows accelerators in FPGAs to be
  19           coherently attached to a CPU via an MMU.  This driver enables
  20           userspace programs to access these accelerators via /dev/cxl/afuM.N
  21           devices.
  22
  23           CAPI adapters are found in POWER8 based systems.
