Maxwell looks the same as Kepler regarding reclocking. Somebody just have to confirm there aren't any differences. And if there are some, they should be small. I was able to reclocking a 1gen Maxwell card already. And for 2gen Maxwell reclocking we need more signed firmware from Nvidia. So yeah, that's nearly done too.

Also, FYI, somewhat better power management has been around for a while for most AMD/ATI GPUs. Maybe like 5 years or maybe even more. I refer to long-obsoleted "dynpm" and "profiles", which worked for Radeons ages and ages ago, even before GCNs appeared and there were only VLIW Radeons around, not even AMD's design. Not just it switched frequencies based on vbios tables, dynpm was even able to go up and down on its own, providing automatic freq scaling. Though it had some technical issues related to poor timings and associated visual glitches. From realistic point of view, nouveau isn't on par even with this prehistoric state of Radeon things, because as far as I understand there is no automatic reclocking, not even half-broken like dynpm. Needless to say, manual reclocking is a thing of limited use and only few most hardcore users are ok with it like this. Getting automatic reclocking right took AMD a while, even when they did it like in proprietary driver does it caused a plenty of woes, due to vbios quirks, strange tables content and other fancy crap catalyst worked around "somehow", and nobody knows how, not even AMD, they do not remember it. There're still some fancy bugs. Some GPUs are running slightly downcloked on opensource driver, otherwise they lose stability, and nobody has got idea what's wrong. Not even AMD devs. Nouveau got long way before something like this would even turn into issues. You can't even face bugs when code is missing or incomplete. But its not a feature :P.
But still, great progress and impressive benchmark results. Compared to results without reclocking, difference is epic. It is expected. But still epic.

nope. Dynamic reclocking only needs stable reclocking. I already have some work in progress for gt215+ nvidia GPUs. For boosting Nouveau has to be sure to not draw too much power out of the GPU, but that will come next most likely (and then maybe dyn reclocking) anyway. I am sure we will manage to finish this also this year.
