16	  Select this option to enable the ocxl driver for Open
17	  Coherent Accelerator Processor Interface (OpenCAPI) devices.
18
19	  OpenCAPI allows FPGA and ASIC accelerators to be coherently
20	  attached to a CPU over an OpenCAPI link.
21
22	  The ocxl driver enables userspace programs to access these
23	  accelerators through devices in /dev/ocxl/.
24
25	  For more information, see https://opencapi.org.
26
27	  This is not to be confused with the support for IBM CAPI
28	  accelerators (CONFIG_CXL), which are PCI-based instead of a
29	  dedicated OpenCAPI link, and don't follow the same protocol.

31	  If unsure, say N.
