# Open Coherent Accelerator (OCXL) compatible devices

config OCXL_BASE

	bool

	default n

	select PPC_COPRO_BASE



config OCXL

	tristate "OpenCAPI coherent accelerator support"

	depends on PPC_POWERNV && PCI && EEH

	select OCXL_BASE

	default m

	help

	  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.
