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.

Replace list_entry with list_{next/prev}_entry.

I've splitted my big series between the part which actually fixes the engine reclocking bits and the part handling voltage/clock updates on temperature change, so that the more reviewed parts can be merged in faster. This series fixes a lot of Engine reclocking issues found on Fermi, Kepler and all Maxwell generation GPUs. It does _not_ fix memory reclocking on Fermi. It mostly contains of

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 v2: boost_mode can now be changed at runtime minor fixups Karol Herbst (22): bios/volt: handle voltage

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
