Raspberry PI 4 GPU Bare Metal Examples

This repository contains examples of code using the Raspberry PI 4 GPU (V3D) on a bare-metal environment.

Most of the interesting code (related to the GPU) lies in src/kernel/examples/, the rest is mostly runtime and utilities. Currently, the code contains a single example that demonstrates how to render a triangle using the GL API commands provided by the GPU.

Examples

  • src/kernel/examples/cl_example.cpp : rainbow triangle

TODO:

  • add more GL examples (spinning cube, suzanne)
  • write a mini opengl implementation example?
  • research how to use vulkan commands
  • add other types of jobs supported by the GPU (namely CSD for Compute Shader Dispatch and TFU for Texture Formatter Unit)
  • some parts still need cleaning
  • write some documentation about the GPU
