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.
