I understand that tegra186_gpio_irq can be caused by many factors.
I understand that you want to separate the various issues.
This Plugin/Out issue may not be related to the irq issue that occurs when entering suspend mode.
However, I think this Plugin/Out issue is related to the irq issue with stopping gdm and unplugging the HDMI cable.
The reason is that the trigger is ultimately triggered by unplugging the HDMI cable.
Also, This problem is already reproduced in EVK, not CustomBoard.
I understand that it is difficult to check and debug each customer’s HW design individually.
I think xavier nx carrier board may not hit this issue. But I need double confirm on your side, so please do this test on this side as well.
What we need to do here is focus on how to reproduce this issue on devkit. What setup… How to trigger.
Sorry that what you are doing here is not logical.
You said, “What we need to do here is focus on how to reproduce this issue on devkit.”
Therefore, at your own request, We purchased EVK, Spend time and money, finally found a way to reproduce it with EVK.
And if EVK finally has a problem, will they further ask the user to Debug it?
You don’t even try to see if it occurs in your Display?
If it occurs in EVK, NVIDIA should be a little more proactive and take the initiative to resolve it.
I don’t think disabling gdm is an abonormal action.
For example, if the user wanted to use EVK in clamshell mode, would disable gdm and unplug the HDMI cable.
