Bug Description
PCI Express non-transparent bridge (NTB) acts as a gateway that enables high performance, low overhead communication between two intelligent subsystems, the local and the remote subsystems. The NTB allows a local processor to independently configure and control the local subsystem, provides isolation of the local host memory domain from the remote host memory domain while enabling status and data exchange between the two domains.
