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.

23 CAPI adapters are found in POWER8 based systems.
