Hello Paulo,
Power management is made of different things:
* reclocking the memory and the engines: this is supported on some Tesla cards
(>G92), all Kepler ones and on the first generation of Maxwell (GM10x). In
that regard, the Arch Linux wiki is right, as Pascal cards do not support
reclocking.
* power- and clock-gating: there’s some ongoing work for it, but none of the
cards have upstream support for it.
* automatically suspending the card when it is not used (only for Optimus
setups): this should work for most laptops (except for MacBooks). This is
what the Fedora wiki is referring to.
There is also adjusting the voltage, changing the fan speed, and probably a few
others.
> there's no DONE stamp on the Power management row. Is this up-to-date?
I think so, as power- and clock gating are not supported yet, power management
support is not done yet. But the [power management feature matrix][1] seems to
be a bit out-of-date.
Cheers,
Pierre
