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 https://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.
