# # 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 select HOTPLUG_PCI_POWERNV 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.
