22 select CXL_AFU_DRIVER_OPS
26 Select this option to enable driver support for IBM Coherent
27 Accelerators (CXL). CXL is otherwise known as Coherent Accelerator
28 Processor Interface (CAPI). CAPI allows accelerators in FPGAs to be
29 coherently attached to a CPU via an MMU. This driver enables
30 userspace programs to access these accelerators via /dev/cxl/afuM.N
33 CAPI adapters are found in POWER8 based systems.
