AFAIK the open source kernel driver pushes a signed proprietary 500Mb firmware blob into the GPU.

The total linux-firmware-nvidia package for Archlinux uncompressed (outer, the firmware blobs are also compressed on top of that) is ~160MB (Mb would be Megabit), with the biggest individual compressed blob being ~50MB.

		You are right the firmware packages are smaller. I mixed it up with the VRAM the GSP uses after being loaded. Point was about the kernel drivers being open-source enabling hackability - they don't, the card hardware is just as closed as before.
