| 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 | |
| 31 | devices. | |
| 32 | ||
| 33 | CAPI adapters are found in POWER8 based systems. | |

| 35 | If unsure, say N. |
