Phoronix: Nouveau Gallium3D Begins Landing RTX 30 "Ampere" GPU Driver Code

Early bits of NVIDIA GeForce RTX 30 "Ampere" support were merged today into Mesa 22.2...

I don't quite understand one thing. Can't Nouveau kernel driver use GSP firmware and provide power management just like this new open source Nvidia kernel driver does? If I recall correctly even Nvidia hinted possibility of doing that. What is the blocker here? Thanks in advance for any good explanation.

It would work for Turing/Ampere, wouldn't work for Pascal/Maxwell.

I'm genuinely curious and I'm not trolling at all: are there any GPUs nouveau supports perfectly, i.e. everything works and there are no crashes, freezes, etc. etc. etc.?

Last time I tried it with my GTX 660 I stumbled upon a critical bug in less than half an hour.

Got a link to the bug report?

Never bothered to file one, since I needed my PC to work right away. Must have been fixed already.

considering chrome was blacklisting nouveau for hardware acceleration, probably that is true.

That's some reason but at least it would work for Turing and Ampere where currently it doesn't work for anything newer than Kepler (and some first gen Maxwell).

I used this gpu too until recently. Are you talking about graphic freezes?

I asked Nouveau developers about this: this is an old bug in their firmware for this card that causes hangups. They do not know how to fix it. And this is not their fault: NVidia did publish no specs or full-fledged firmware for these old cards.

There's a workaround: one can extract firmware from their propietary driver and add a parameter to kernel command line to make it load this firmware. This is illegal, though.

Freezes, crashes, all of it. I sold the card a long time ago but thank you for the input! Congrats on signing up!
