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

The temp_get() function currently returns negative error numbers or a temperature. However, the thermal sensors can (in theory) measure negative temperatures. Some implementations of temp_get() correctly clamp negative temperature readings to 0 so that users do not mistake them for errors, but some, like gp100_temp_get(), do not. Rather than relying on implementations remembering to clamp values,

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,

As you changed the return value of `temp_get()` to solely be the error code, or absence of an error, I would change all those tests that checked whether the returned value was strictly less, or greater than, 0 to now only compare against 0 (no error). For example, if (therm && therm->attr_get && nvkm_therm_temp_get(therm, &val) < 0) if

The current hwmon code doesn't check if the returned value was actually an error. Since Kepler temperature sensors are able to report negative values. Since Pascal (and maybe earlier) we have sensors with improved precision. Adjust the nvkm_get_temp method to be able to deal with those changes and let hwmon return an error properly.

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

The current hwmon code doesn't check if the returned value was actually an error. Since Kepler temperature sensors are able to report negative values. Those negative values are not for error reporting, but rather when you buried your GPU in snow somewhere in Antarctica and still want a valid temperature to be reported (unverified). Since Pascal (and maybe earlier) we have sensors with

We should simply return errors while the GPU is turned off, because the sensors aren't accessable and setting any kind of value doesn't make any sense.

Commit d32656373857 ("drm/nouveau/therm/gp100: initial implementation of new gp1xx temperature sensor") added support for reading finer-grain temperatures, but continued to report temperatures in 1 degree Celsius increments via nvkm_therm_temp_get(). Rather than altering nvkm_therm_temp_get() to report finer-grain temperatures, which would be inconvenient for other users of the
