[PATCH 0/9] Groundwork for clocking fixes
This series contains a lot of groundwork to finally fix reclocking issues on
Kepler+ gpus.
There shouldn't be any functional changes with the first patch being the only
exception (fixes some voltage table parsing issues with of few kepler gpus)
The most interessting thing is the tool in the last patch, which can be ran
alongside the nvidia driver to test nouveaus volting code and print the

[PATCH 00/19] Volting/Clocking improvements for Fermi and newer
This series fixes most of the issues regarding volting on GPUs with any form
of GPU Boost inside their vbios, which is mainly Kepler and newer, but we find
some boosting related tables in Fermi vbios' already
In the end reclocking should work on most Kepler cards without any issues

[PATCH v3 00/29] Volting/Clocking improvements for Fermi and newer
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

[PATCH v4 00/37] Volting/Clocking improvements for Fermi and newer
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.
