- Select this option to enable driver support for IBM Coherent
- Accelerators (CXL). CXL is otherwise known as Coherent Accelerator
- Processor Interface (CAPI). CAPI allows accelerators in FPGAs to be
- coherently attached to a CPU via an MMU. This driver enables
- userspace programs to access these accelerators via /dev/cxl/afuM.N
- devices.
- CAPI adapters are found in POWER8 based systems.
- If unsure, say N.
