- 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.
