+ Select this option to enable the ocxl driver for Open
+ Coherent Accelerator Processor Interface (OpenCAPI) devices.
+
+ OpenCAPI allows FPGA and ASIC accelerators to be coherently
+ attached to a CPU over an OpenCAPI link.
+
+ The ocxl driver enables userspace programs to access these
+ accelerators through devices in /dev/ocxl/.
+
+ For more information, see http://opencapi.org.
+
+ This is not to be confused with the support for IBM CAPI
+ accelerators (CONFIG_CXL), which are PCI-based instead of a
+ dedicated OpenCAPI link, and don't follow the same protocol.
+
+ If unsure, say N.
