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.
