i.MX8MP NXP BSP 6.6.3 with QtWebEngine 6.9.1 and Chromium 130.0.6723.192

Martin Pfister

I successfully build and can run an image for i.MX8mp, based on NXP's Yocto Linux Guide with BSP 6.6.3 and with QtWebEngine 6.9.1, Chromium 130.0.6723.192.

However when starting the QT Webapplication with Debug flags:

export QT_LOGGING_RULES="qt.webenginecontext.debug=true"
export QT_DEBUG_PLUGINS=1

I get the following output:

qt.core.library: "/usr/lib/qml/QtWebEngine/libqtwebenginequickplugin.so" loaded library
Unable to detect GPU vendor.
Only --use-gl=angle is supported on this platform.
qt.webenginecontext:

Chromium ANGLE Backend: disabled
Chromium Vulkan Backend: disabled

QSG RHI Backend: OpenGL
QSG RHI Backend Supported: yes
QSG RHI Device: Vivante Corporation Vivante GC7000UL OpenGL ES 3.1 V6.4.11.p2.745085
QSG RHI GPU Vendor: Unknown

Using GLX: no

I tried several qtwebengine configure options through qtwebengine_git.bbappend, but for some reasons, qtwebengine Chromium 130.0.6723.192 always expects/allows: [(gl=egl-angle,angle=default),(gl=disabled,angle=none)].

Latest qtwebengine_git.bbappend

Does anybody can help in finding out Chromium 130.0.6723.192 to recognize (gl=egl-gles2,angle=none) to fully support i.MX8 GPU with HW-accelleration.

Previous Release with QTWebEngine 6.5.0, Chromium 108.0.5359.181 and applied patches works but the reason we have to upgrade to QtWebEngine 6.9.1 with Chromium 130.0.6723.192 is to support Angular Applications > Version 16.
