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