IMX8MP Vivante Driver Issues

alexkl — Thu, 16 Jan 2025 18:33:37 GMT

The Vivante driver for the IMX8MP (latest version, version doesn't seem to matter) seems to crash Chromium, crashes in WGPU, and doesn't support EGL_DEFAULT_DISPLAY.

> EGL: Warning: No default display support on wayland

It also throws BadAtttribute when robust access is requested on a GL surface, despite the feature being supported.

1. Is there any plan to support EGL_DEFAULT_DISPLAY on Wayland? Plenty of graphics libraries request the default display.

2. Is there any known issues with Chromium and Vivante? TorizonOS currently does not work on their latest release.

3. WebGL2/WebGPU doesn't appear to work on WGPU-RS based WASM code. It crashes, or is exceptionally slow. Try any of the examples here with a Vivante driver: https://bevyengine.org/examples/

4. Are there any known issues with the driver limitations/stability being worked on for a future release? e.g. robust access

Hello,

Make sure that you are using the latest BSP:

Since we saw this issue in previous version but now it suppose to be fixed, please check it.

Regards

Which specific issue was resolved in the latest BSP? I mentioned that I have tested the latest driver so I would like to not have to repeat all the tests.
