Hello,
How to config software for two jetson agx xavier’s communication using the way ep-to-ep?

3

What is the goal here?
Two PCIe EPs can’t talk to each other as per the PCIe spec.

4

We have Three xavier，one for rp mode，other two xaviers for endpoint mode. Rp xavier can commuicate with the other two ep devices now. But I want the other two ep devices can communicate by ep-to-ep. How to config the software?

5

I’m afraid that is not possible (at least through PCIe).
How about using Ethernet for that?

6

I need more higher speed, so i use pcie interface. If i use pcie switcher, the rp and two ep xaviers all connect to the switcher. Can ep-to-ep communication be possible?

7

If the PCIe switch supports ‘peer-to-peer’ feature, then, it should be possible. In that case, PCIe packets from one PCIe-EP to another PCIe-EP go via the PCIe switch (without really reaching all the way up to RP)

8

Do you have some similar design or case using pcie ep-to-ep for xavier?

9

Unfortunately no.
