Previous blog post: https://codyho.dev/blog/hypervisor-macbook-neo/ What We Did TL;DR: Niklas and I built a fully OpenGL ES 3.0 compliant GPU driver for the M4 Mac Mini and MacBook Neo in about a month, a process which normally takes years. Here is Chrome and Firefox running WebGL on the M4 Mac Mini with working compositing: Most importantly, the driver is fast enough to run Minecraft at 200fps: Building this driver involved reverse engineering the AGX’s (Apple’s name for the GPU) incredibly complicated firmware ABI and user-space components. This was all done in a transparent, verifiably clean room manner using well established techniques. The code is not yet ready for end users, but we are looking to get it to end users as soon as possible. How We Did It Previously, I built a hypervisor to reverse engineer macOS. Now the goal became to actually do something useful with it, and what better target than writing a GPU driver.…
