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.

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

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

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.
