About two AGX Xaiver use PCIE connect

Hello, Nvidia
We designed a custom board, which can insert two AGX Xavier by default.
On the board,
we used PCIE to connect two AGX Xavier by default. So far, it works well.
However, we found that after configuring EP Xavier, we need to restart RP Xavier to correctly identify EP Xavier. But the normal logic of our board is to enable two AGX Xavier to start at the same time.
Do you have a way for RP Xavier to recognize EP without restarting? Maybe it’s a good idea to reset the PCIE driver? But I don’t know how to do it.

You can try to rescan the device in commndline.

Hi, Wayne
thank you, your idea is so good. I try use below commnd to rescan PCIE.
echo 1 > /sys/bus/pci/rescan

I have a new question that I would like to consult. We used X8 PCIE, but the speed of the virtual NIC in our actual test is about 5Gbps, which is far from the physical speed limit. We would like to know how to improve this transmission rate.
