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. | ||
