+	  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.
