tl;dr:Alyssa dives into the rabbit hole uncovered by reverse-engineering AGX to build open source graphics drivers. "The driver fails to render large amounts of geometry. Spinning a cube is fine, low polygon geometry is okay, but detailed models won’t render. Instead, the GPU renders only part of the model and then faults."
tl;dr:"A few weeks ago, I purchased a Mac Mini with an M1 GPU as a development target to study the instruction set and command stream, to understand the GPU’s architecture at a level not previously publicly understood."
