4 PCI Non-Transparent Bridge (NTB) Endpoint Function (EPF) User Guide
9 This document is a guide to help users use pci-epf-ntb function driver
10 and ntb_hw_epf host driver for NTB functionality. The list of steps to
11 be followed in the host side and EP side is given below. For the hardware

130 In order for the endpoint device to establish a link with the host, the _start_
131 field should be populated with '1'. For NTB, both the PCI endpoint controllers
132 should establish link with the host::
134 	# echo 1 > controllers/2900000.pcie-ep/start
135 	# echo 1 > controllers/2910000.pcie-ep/start
