depends on PCI

help
|
|
The PCI-E Non-transparent bridge hardware is a point-to-point PCI-E bus
|
|
connecting 2 systems. When configured, writes to the device's PCI
|
|
mapped memory will be mirrored to a buffer on the remote system. The
|
|
ntb Linux driver uses this point-to-point communication as a method to
|
|
transfer data from one system to the other.
