[Nouveau] Power Management under Nouveau

[Paulo Matos]

Hello,

I would like some clarity from the developers on the state of power
management for nouveau. I have recently acquired a Dell XPS 15 (2017)
9560 with:
00:02.0 VGA compatible controller [0300]: Intel Corporation Device
[8086:591b] (rev 04)
01:00.0 3D controller [0302]: NVIDIA Corporation Device [10de:1c8d] (rev a1)

There seems to be contradictory information online with Arch Wiki
mentioning:
"Note that the open source Nvidia driver Nouveau currently does not
support power management on Pascal GPUs such as the GTX 1050, so
performance is very poor with this driver."
https://wiki.archlinux.org/index.php/Dell_XPS_15_9560

and Fedora wiki saying:
"In fact, you can no longer use the bumblebee software with nouveau any
longer even if you want to. See issue 773 for further information about
this subject. You MUST USE PRIME. The nouveau driver already handles
power saving nowadays so bumblebee would just be superfluous… "
https://fedoraproject.org/wiki/Bumblebee

However when one looks at the nouveau power support matrix:
https://nouveau.freedesktop.org/wiki/FeatureMatrix/

there's no DONE stamp on the Power management row. Is this up-to-date?

Kind regards,
