the problem was the nouveau would do this before when firmware was easy to intercept from the driver (and could be extracted easily). the newer driver uses different methods of firmware upload and it's a real chore to do so now.

so nouveau gave up on it. they also expected nvidia to drop some firmware.

now that newer cards have GSP.bin firmware, which can be interfaced with easily - things are different. i would wager a guess that it's similar to atombios from amd. you just call a function in GSP and it knows what registers to poke with the right values to achieve what you need.
