When configured, writes to the device's PCI 7 mapped memory will be mirrored to a buffer on the remote system. The 8 ntb Linux driver uses this point-to-point communication as a method to 9 transfer data from one system to the other. 10 11 If unsure, say N. 12 13if NTB 14 15config NTB_MSI 16 bool "MSI Interrupt Support" 17 depends on PCI_MSI 18 help 19 Support using MSI interrupt forwarding instead of (or in addition to) 20 hardware doorbells.
