Xillybus is a generic interface for peripherals designed on
|
|
programmable logic (FPGA). The driver probes the hardware for
|
|
its capabilities, and creates device files accordingly.
|
|
|
|
If unsure, say N.

Set to M if you want Xillybus to use PCI Express for communicating
|
|
with the FPGA.

Set to M if you want Xillybus to find its resources from the

system, say M.
