It is only a small piece of documentation Nouveau developers need. Looks more like a show than a genuine help. Also it is a link from 2013...

1) Those documents are no longer available (or the link is broken) 2) The contribution was actually not very helpful for nouveau, much of the information was already known. nvidia has done practically nothing since then to support nouveau in any meaningful way, with the exception of a one-off patchset to implement some support for Tegra. I suspect you just found the first link that seemed to validate the point you are trying to make, without actually understanding what is actually (not) going on.

Funny, I think the same thing when people say "nvidia never helps nouveau."

    It happened once and 5 years ago. And not a big deal anyway.

    Good thing nvidia hardware has not changed one bit since they released that limited amount of information in 2013!

      that was 1 doc out of many on http://download.nvidia.com/open-gpu-doc/ http://download.nvidia.com/open-gpu-doc/ multiple docs have been updated in this past year

      There's a reason I said "that directory" not "that file." Cutting through the sarcasm, here's some Volta info: https://download.nvidia.com/open-gpu-doc/Display-Ref-Manuals/1/gv100/ https://download.nvidia.com/open-gpu-doc/Display-Ref-Manuals... As reported on in phoronix: https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-Volta-GV100-Firmware https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-V... https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-Volta-Display-Headers https://www.phoronix.com/scan.php?page=news_item&px=NVIDIA-V...

        "Before getting too excited, this is strictly about the display hardware and not about the 3D engine, etc." - from the link you gave. So still a show but not a real help.

Isn't the current problem that modern cards will never exit a very low power boot up state with dogshit performance since that requires a signed firmware of some sort? I think that sums it up nicely. Nvidia want the opensource driver to work just well enough that you can get a picture to install the proprietary one.
