Banana Pi BPI-F3 RISC-V OpenGL problem

Hello!

We recently bought a Banana Pi BPI-F3 RISC-V board with the intention of using it as a platform for running a graphics application written in Qt6.

However, both on Minimal (with X11 installed) and on Desktop versions of Bianbu 2.0.1, even the simplest graphics in FullHD work with 40-42 FPS maximum. At the same time, when using OpenGL, the FPS drops to 1 frame every 5-10 seconds.

The glmark2 tests showed 7 FPS, and also that softpipe is used as the GL_renderer. Although when running WebGL Aquarium, the web browser gives 30 FPS.

Can someone tell me what we did wrong? Because when opening several windows with graphics, everything works much faster than in one large one.

Just got the board and used the Bianbu 2.0.4 image and same here. No HW accelerated OpenGL or Vulkan (vulkainfo just segfaults), only softpipe. Are the graphic drivers missing from the image or are there no proper GPU drivers at all?
