From: Martin Peres <martin.peres at labri.fr> This should fix a deadlock that has been reported to us where fan_update() would hold the fan lock and try to grab the alarm_program_lock to reschedule an update. On an other CPU, the alarm_program_lock would have been taken before calling fan_update(), leading to a deadlock. We should Cc: <stable at vger.kernel.org> # 3.9+ Reported-by:

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

This is an updated series for the old clocking improvement one. I think I got everything needed in place and also a simple update mechanism for updating the cstates/voltage on temperature changes. If anything is unclear how I REed or got the information, please leave a note so that I can provide additional information in the commits. Besides that I think we are pretty close now and only some

We are slowly getting there! v4 of the series with some realy good improvements, so I am sure this is like 95% done and only needs some proper polishing and proper Reviews! I also added the NvVoltOffsetmV module parameter, so that a user is able to over and !under!-volt the GPU. Overvolting makes sense, when there are still some reclocking issues left, which might be solved by a higher voltage.

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,

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
