IMX8 GPU crash

[JoRadio]

When I run the Benchmark test of Qt5.15 on IMX8, the system crashed after running for half an hour, and the GPU printed the dump information. What causes this? The Texture Size I use is 1024x1024. I enable IBL Lighting and SkyBox. The Material used is Original Material, and the default values are selected for other configurations.

This is the download link for Benchmark：

The attachment is the print information after the GPU crash.

Hello @JoRadio,
The crash is likely due to GPU memory exhaustion. The i.MX8MP’s Vivante GC7000UL GPU has limited memory, and enabling IBL Lighting, SkyBox, and using 1024×1024 textures can overwhelm it over time. Try reducing texture size to 512×512 or disabling IBL/SkyBox incrementally to isolate the cause.

Best Regards,

Hi @JoRadio 

Sorry to reply late, Which BSP code do you use? 

The i.MX8MP uses the Vivante GC7000UL GPU, which has limited GPU memory.
Enabling Image-Based Lighting (IBL) and SkyBox with large textures (1024x1024) can consume significant GPU memory.

Here are some suggestions:

1. Reduce texture resolution:

Reduce the texture from 1024x1024 to 512x512 or 256x256 and observe if it still crashes.

2. Gradual disabling feature:

First, turn off the SkyBox or IBL lighting and gradually identify which feature is causing the problem.
