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. This is also preparation work of

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.
