help
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.
