CONFIG_NTB: Non-Transparent Bridge support

General informations

The Linux kernel configuration item CONFIG_NTB has multiple definitions:

Non-Transparent Bridge support found in drivers/ntb/Kconfig

The configuration item CONFIG_NTB:

• prompt: Non-Transparent Bridge support
• type: tristate
• depends on: CONFIG_PCI
• defined in drivers/ntb/Kconfig
• found in Linux kernels: 4.2–4.20, 5.0–5.19, 6.0–6.11, 6.12-rc+HEAD
• modules built: ntb

Help text

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.

If unsure, say N.
