This was the first step of the secure boot refactoring - as Ben asked for some fixes, I now submit it as its own series to make it easier to review (and also because rebasing secure boot on top of this takes time and I don't want to do it until this is validated!). This series attempts to factorize the duplicate falcon-related code into a single library, using the existing nvkm_falcon

Two trivial PMU-related fixes for Tegra: - Add a dummy func member to GK20A, since nvkm_pmmu_pgob() unconditionally dereferences it - Check whether a PMU actually exists before calling nvkm_pmmu_pgob(). During early bringup we are likely to not have a PMU Alexandre Courbot (2): pmu/gk20a: add dummy func gr/gf100: do not assume a PMU is present drm/nouveau/nvkm/engine/gr/gf100.c | 3 ++-

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

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 3. racy reclocking while GPU is suspending and leading to hangs Some of the patches were part of the bigger reclocking series I sent months ago, some things have changed though.

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 3. nouveau always does full reclocks even if only a change of the voltage is required Some of the patches were part of the bigger reclocking series I sent months ago, some things have changed though.

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,

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.
