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