So NVIDIA "released" their kernel driver as open source. By which they mean, they moved most of it to firmware and made the open source driver call into it. There are almost 900 functions implemented in the 34MB firmware, give or take, from what I can see. Broadcom vibes...

For reference, Apple's GPU firmware is ~400kB. Apple's display controller, which is a similarly insane RPC mess, is ~7MB, but most of it is data tables (~1.5MB is code). Don't get me wrong, less blobs in the kernel is great... but open source their "driver" they did not.
