3 tristate "Non-Transparent Bridge support"
4 depends on PCI
5 help
6 The PCI-E Non-transparent bridge hardware is a point-to-point PCI-E bus
7 connecting 2 systems. When configured, writes to the device's PCI
8 mapped memory will be mirrored to a buffer on the remote system. The
9 ntb Linux driver uses this point-to-point communication as a method to
10 transfer data from one system to the other.

19 Support using MSI interrupt forwarding instead of (or in addition to)
20 hardware doorbells. MSI interrupts typically offer lower latency
21 than doorbells and more MSI interrupts can be made available to
22 clients. However this requires an extra memory window and support
23 in the hardware driver for creating the MSI interrupts.
