The Open Graphics Stack
summary
Open source graphics is the status quo and is production ready for embedded Linux with concrete pieces that work together: Mesa provides user‑space drivers and implements OpenGL Vulkan and OpenCL, using NIR and SPIR‑V front ends; the Panfrost driver targets Arm Mali hardware and runs on mainline kernels; kernel subsystems DRM/GEM handle memory mapping, unified memory and GPU scheduling; Vulkan lowers CPU overhead by removing the GLSL parser; credible reverse‑engineered stacks exist for Qualcomm and Apple.
