Hello,

You’ve made significant progress in exploring hardware acceleration features in Chromium on the Verdin iMX8MP with Torizon 7.1.0. Let’s address your observations and questions:

1. WebGPU and Canvas Out-of-Process Rasterization:

   • WebGPU: This is an experimental feature designed to enhance graphics performance in web applications. While enabling it with --enable-unsafe-webgpu allows testing, it may not be stable or fully supported on all hardware, so proceed with caution.
   • Canvas Out-of-Process Rasterization: This feature can improve rendering performance by offloading rasterization tasks to separate processes, potentially enhancing responsiveness and reducing main thread load. The flags you’ve used are correct for enabling this feature.

2. Testing Improvements:

   • To assess the impact of these changes, utilize performance profiling tools available in Chromium’s developer tools. Monitor rendering times and frame rates to evaluate improvements when these features are enabled.

3. MSAA Performance on Vivante GPUs:

   • The issue with MSAA (Multisample Anti-Aliasing) performance is a known limitation of the Vivante GC7000UL GPU, likely due to hardware constraints. The workaround (msaa_is_slow) is applied to mitigate performance degradation by disabling MSAA where it’s not beneficial.

4. Hardware and Software Limitations:

   • The performance limitations you’re experiencing may be inherent to the hardware capabilities of the Vivante GPU. While software optimizations can help, they cannot overcome fundamental hardware constraints. Keep an eye on updates from NXP and Toradex for any software optimizations or patches that could improve performance.

In summary, while enabling these features can potentially improve performance, the extent of improvement is constrained by the hardware. Continue experimenting with these settings to find the best configuration for your application needs.

Best regards,

GPU Monitoring on TorizonCore

Hello, I was wondering how to monitor GPU usage on TorizonCore. I am using TorizonCore 6.1.0 with a Verdin iMX8M Plus. I tried modifying the image using Yocto and following this: Install gputop on imx8mp verdin - Technical Support - Toradex Community However, this did not work as intended. No gpuProfiler seems to be there and gpuinfo.sh script returns that the platform is not supported. What is a simple way to monitor GPU usage on TorizonCore ? Thank you for your help.
