[35.4.1] LAN Tx performace is getting lower when HDMI is plug out

Hi,
we used Xavier NX devkit with the official image: JP512-xnx-sd-card-image.zip.
We found that without HDMI connection, the TX performance of LAN will be lower than that with HDMI connection.
With HDMI, the TX performance can be above 949 Mbits/sec.
Without HDMI, the TX performance will reach to about 788 Mbits/sec.

The command I used on the Xavier NX devkit: iperf3 -s
The command I used on my PC side: iperf3.exe -c 192.168.100.100 -B 192.168.100.101 -t 12000 -R

We have tested Intel I210 and Asix Ax88179 and both of them will have the same issue.

The following shows the iperf logs.
0.00-14.00 sec: HDMI is plug in.
14.00-100.00 sec: HDMI is plug out.
100.00-137.00 sec: HDMI is plug in.

你之前不是問過了嗎…?

Didn’t you ask same question before?

3

Hi @WayneWWW ,
之前問的是RX，且是在4.6.1。
這次問的是TX，是在Jetpack 5.1.2。

4

請問你關掉EEE測試了嗎

Have you tried to disable EEE?

5

Hi @WayneWWW ,
關掉EEE還是會發生問題，TX在沒有接HDMI下，會掉到780多Mbits/sec。

謝謝。

6

Are you able to reproduce this issue with on board ethernet instead of PCIe LAN?

7

Hi @WayneWWW ,
我是用Nvidia Xavier NX devkit公版複製到問題的。devkit只有一個on board LAN。謝謝。
I used Nvidia Xavier NX devkit, which has onboard ethernet LAN.

8

厄… 我當然知道devkit上只有一個on board LAN.

我的問題是你前面提到 I210跟ax88179. 我是想請問這個問題能不能透過devkit上的on board LAN複製到…
意思是先不管什麼i210, ax88179這些第三方的PCIe/USB LAN.

We have tested Intel I210 and Asix Ax88179 and both of them will have the same issue.

9

Hi @WayneWWW ,
不好意思耶。我還是不太清楚您的問題。
您是說我要找一個on board LAN然後與devkit的on board LAN對接做測試嗎?

10

對, 比方說兩個devkit的on board LAN對接 然後有一邊插HDMI進行你說的實驗.

另外, 進行實驗的時候麻煩確認jetson_clocks都有在跑

11

Hi @WayneWWW ,
我使用兩個on board LAN對接，如下log，performance有到 0 bits/sec。

請問能確認一下這個行為跟HDMI真的有直接關聯嗎?

Could you confirm if this behavior is really related to HDMI?

14

Hi @WayneWWW ,
是的，目前看起來 Xavier NX devkit在沒有HDMI時，TX performance會較差。

15

請問你能提供一下devkit on board LAN 在 HDMI有接著的時候的數據嗎？

17

Hi @WayneWWW ,
0.00-61.00 sec: HDMI plug in
61.00-125.00 sec: HDMI plug out
125.00-141.00 sec: HDMI plug in

Hi,

我會再進行測試. 謝謝提供數據

Hi,

We are still not able to reproduce your issue with both host/client side has no monitor connected.

Hi,
我們使用您的command於Xavier NX devkit，還是會發生問題耶。
