Why 0xff? I mean, sure, there is a high possibility that the GPU won’t like
temperatures above 255℃, but still.

[RFC PATCH 00/13] Thermal throttling
Adds Nouveau controlled thermal throttling for Kepler+ GPUs. With this I feel
safe enough to add support for Maxwell2 reclocking later on (still hidden
behind a switch, but we can be fairly sure to not overheat hardware if a user
isn't carefull enough)
Contains all patches from my clk update series, but I thought it makes sense
to include those in this series as well for completness.
Please

[RFC PATCH 00/29] Current State of my clk patches
Just wanted to post updated versions of my last series/patches. Reviews
welcomed.
It would be also nice if we agree on features I should focus upstreaming, so
that this work can be better splitted or reordered.
Sadly most of my patches depend on the rather big clk subdev rework and I think
those patches shows best, why I think this rework is actually needed and makes
things much easier to add

[PATCH 00/32] Updated State of my clk patches
Last update here: https://lists.freedesktop.org/archives/nouveau/2017-September/028848.html
Basically big cleanup, reordering, simplifications and some renaming to make
the code easier to read and to review. I also moved some bugfixes to the front
so they can be merged prior the other patches.
There was also a bug related to the therm daemon triggering a pstate change
leading to PMU lockups,
