3 tristate "Non-Transparent Bridge support"
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.
17 bool "MSI Interrupt Support"
20 Support using MSI interrupt forwarding instead of (or in addition to)
21 hardware doorbells. MSI interrupts typically offer lower latency
22 than doorbells and more MSI interrupts can be made available to
23 clients. However this requires an extra memory window and support
24 in the hardware driver for creating the MSI interrupts.

32 tristate "NTB Transport Client"
34 This is a transport driver that enables connected systems to exchange
35 messages over the ntb hardware. The transport exposes a queue pair api
