16 Select this option to enable the ocxl driver for Open
17 Coherent Accelerator Processor Interface (OpenCAPI) devices.

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 http://opencapi.org.

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.
