IMX8 GPU crash

JoRadio — Tue, 13 May 2025 03:18:43 GMT

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：

BenchmarkDemo · master · public-demos / qtquick3d · GitLab

The attachment is the print information after the GPU crash.

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.

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.
