RPi 3, Broadcom EGL library, and Chromium

Thu Dec 05, 2019 10:08 pm

Hello.

When I switching from fKMS to Legacy non-GL driver (that's providing hardware accelerated OpenGL ES but software OpenGL), the Chromium browser is now using llvmpipe, not hardware accelerated OpenGL ES. If I set --use-gl=egl parameter, nothing changes. I see that Chromium uses libGLESv2.so.2 from the Mesa package, that's becoming software if I use proprietary OpenGL ES. In my case, Chromium needs to use libGLESv2.so library, not *.so.2. Or libbrcmGLESv2.so.

If I remove libGLESv2.so.2 and make symlink to /opt/vc/lib/libbrcmGLESv2.so (and for EGL too), then I have this error:

Code: Select all

It seems that the default Chromium build is depending of Mesa EGL, and cannot work with the Broadcom EGL. Is there a build that's linked with the Broadcom OpenGL ES and EGL?
