This series addresses various issues inside the reclocking code: 1. after resume the set clocks are reset 2. reclocking not possible while GPU is suspended Some of the patches were part of the bigger reclocking series I sent months ago, some things have changed though. This is also preparation work of changing the clock state due to temperature changes and dynamic reclocking. v2: remove commits

I made a little changes in this series: 1. merge the two last patches together 2. unify the private data interface with the drm debugfs one now it should be very obvious for a new dev on how to add new files to debugfs and how to get access to the nouveau structs Karol Herbst (5): debugfs: add infrastructure to add files with other fops than only read debugfs: rename functions to

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

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

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,
