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.
