Currently nouveau does no power management, meaning that
* voltage control
* clock control
* clock gating
* ASPM

are all running on default (set by bios) settings. It's has been worked on
for
a while now and there is still more work needed

This is not the appropriate forum to track "power management not
supported"
issues. This is something that's being worked on, when it's supported,
should
it not work, feel free to file bugs then.

Do you really understand that Nvidia-based 1500-3000$ laptop may be really
killed by overheat with pretty non-binary / no-blob / GPL-friendly opensource
driver? Are you kidding? :)

It seems Linus Torvalds was right about Nvidia and their (Optimus) hardware.


OK, Ilia. Where do yo recommend to post such report about  "power
management
not supported" issues?

The temperatures you've mentioned will not kill your laptop.

There is not much of a benefit in (re-)posting "power management does not
work", most people are aware about this and working on it one way or the
other.
If you really want to help, be more understanding and work with the nouveau
team rather than posting annoying replies.

Btw have you realised the _massive_ amount of work that PM is ? The AMD/ATI DPM
code that landed in linux 3.11 is over 50kloc and all of it was done by the
vendor.

Thanks

I really understand. But no amount of understanding will make it a good idea to
file bugs about it. [Also note that most CPU/GPU chips have overheat
protection.]

I would recommend sitting tight and waiting for this functionality to be
released. The Nouveau project's devs are well aware of the lack of power
management support. You can also come to #nouveau and see if some devs are
willing to share their reclocking scripts with you, although it's more than
likely that the answer will be "no" or that they won't work at all
for you.
