Video-Mixer Modetest & Kernel Call trace Issue
Hi, I created and tested the design by following your doc for the ZCU102 board using Vivado/Petalinux 2022.1. There was no problem testing bare-metal design.
In the petalinux side, there was no problem working with MIPI capture pipelines. However, there was a problem working with the Video Mixer Pipeline. While doing the modetest, I did not found any planes information. I have attached some part of it below.

I did not find any information of mixer crtc connection with DP Encoder in your system-user.dtsi. My pl.dtsi did not have that information either. So, I updated it from system-user.dtsi file
&v_mix{
crtc_mixer_portv_mix: port@0 {
reg = <0>;
mixer_crtc:endpoint{
reg=<0>;
remote-endpoint=<&dp_encoder>;
};
};
};
&zynqmp_dpsub{
dp_port: port@0 {
reg = <0>;
dp_encoder: endpoint {
remote-endpoint = <&mixer_crtc>;
};
};
};
While doing the modetest, I got some more information about the vmixer planes.

Then, I entered the following command
modetest -D a02b0000.v_mix -s 51:1920x1080@BG24
I got following issues.
