Banana Pi BPI-F3 RISC-V OpenGL problem

Banana PI RISC-V Design BPI-F3/BPI-CM6(SpacemiT K1)
1

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?

Hi, same issue here: A Qt6 application, even without OpenGL, renders so slowly that it freezes and causes one CPU core to stay at 100% usage continuously. I managed to run OpenGL programs and games, but they only work with softpipe and run at very low FPS. However, the WebGL Aquarium on Chromium runs smoothly at 30 FPS, so there must be some drivers available, but it seems like there’s a missing porting or something similar for OpenGL.

I’m on bianbu 2.2 is there any news regarding this issue?
