Can anyone provide any information on getting the GPU driver working with a Banana Pi M2 Zero? It supposedly has a Mali 400 GPU.
In my tests, it seems I am stuck with Mesa software rendering with OpenGL. When I write a program that creates an OpenGL 2.0 ES context, the vendor and renderer both list Mesa and performance is terrible (2-10 fps and GLSL shaders are incorrect) when rendering even the simplest scenes. I am using DRM (Direct Rendering Manager) with boots straight to a CLI and no desktop environment if that makes any difference. With the same code and same conditions on a Raspberry Pi Zero 2 W, OpenGL works perfectly in my tests.
I am using the most recent Armbian linked on the banana pi wiki page for the product.
I tried to build the Mali driver for the Mali 400 GPU from source using this command:
KDIR=/lib/modules/`uname -r`/build USING_UMP=0 BUILD=release make
But receive this error:
Makefile:122: CONFIG_TRACEPOINTS required for profiling
Makefile:92: /lib/modules/6.0.9-sunxi/build/.config: No such file or directory
make: *** No rule to make target '/lib/modules/6.0.9-sunxi/build/.config'. Stop.
When I think means I don't have header sources for my kernel. I looked through apt cache and it doesn't have the source for my kernel listed.
What can I do to get actual OpenGL ES 2.0 GPU hardware support (or even OpenGL 3.0 core profile) working on this hardware with Armbian?
