Hello Samarth,
Thank you for reaching out with your question about GPU acceleration on the iMX8MP using wxWidgets. It sounds like you’re encountering an issue with the Vivante drivers. Let’s go through some steps to help resolve this:
-
Verify Driver Installation: First, ensure that the Vivante GPU drivers are installed in your container. These drivers are crucial for enabling hardware acceleration on the iMX8MP. Check if the package
libgal-vivante1
or a similar package is installed in your container. -
Container Configuration: Make sure your Wayland-Vivante container is configured to access the GPU. This typically involves ensuring that the
/dev/galcore
device is accessible within the container. You can achieve this by adding the following to your Docker run command:--device=/dev/galcore
-
Weston Configuration: Since you are using a Weston container for the GUI, ensure it is correctly set up to communicate with your application container. This involves sharing the Wayland socket between the containers. You can do this by bind-mounting the
/tmp
directory:-v /tmp:/tmp
This allows the Wayland client (your application) to communicate with the Weston compositor.
-
Check Permissions: The error message about the runtime directory suggests a permissions issue. Ensure that the UID and GID used in your container match those expected by the Weston container. You might need to adjust the user running the application to match the UID 1000.
-
Troubleshooting: If the Vivante drivers are still not found, verify the library paths in your container. The error indicates that the library is being searched in
/usr/lib/dri
. Ensure that the Vivante driver files are present in the expected directories or adjust theLD_LIBRARY_PATH
to include the correct path.
By following these steps, you should be able to resolve the issue with the Vivante drivers and ensure that your application can utilize GPU acceleration effectively on the iMX8MP with Torizon.
If you have any further questions, feel free to ask.
