Does NvStreams support IPC communication crossing XavierA and XavierB on DriveAGX, for example producer on one Xavier and consumers on the other Xavier, and the interface could be 1G/10G/100M ethernet, CAN and PCIe.

If it is feasible for inter-Xavier communication using NvStreams, how to integrate NvStreams with NTB and Ethernet?

Dear @hfkou,
Nvstream does not support inter Xavier communication.

4

Regarding PCIe connection between XavierA and XavierB, besides NTB, is there another approach for Inter-Processor communication between XavierA and XavierB through PCIe?

5

Dear @hfkou,
Did you check https://docs.nvidia.com/drive/driveworks-4.0/dwx_ipc_socketclientserver_sample.html?

6

Yes, this IPC sample is using network sockets at the higher level, while NTB at lower level converts PCIe into network interface through networking stack.
At lower level, besides NTB, does NV or your parters provide any other solution, for example directly PCIe w/o going through networking stack?

No.
