OpenCAPI allows [31mCONFIG_FPGA[0m 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 [31mCONFIG_PCI[0m-based instead of a dedicated OpenCAPI link, and don't follow the same protocol. If unsure, say N. |
