info.min and info.max doesn't always represent the actual voltage range we can use. Do the same as with the entry based volting. Fixes "ERROR: Can't get value of subfeature in0_min: Can't read" errors in sensors.

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

With these both patches, most of the kepler cards should be able to reclock their core clock without issues. These patches should be tested carefully among nouveau devs, so that these don't break reclocking on other cards (especially Teslas). Particularly the second one might break reclocking here and there. Karol Herbst (2): bios/volt: handle voltage table version 0x50 with 0ed header

Some Tegra drivers might be compiled as kernel modules, and they need the fuse information for initialization. One example is the GK20A Nouveau driver. It needs the GPU speedo value to calculate frequency-voltage table. So export the tegra_sku_info.

On a very few GPUs with the voltage table version 0x50 we have to read out the VIDs out of the entries of the table, where all the other gpus are either PWM based or get a base and a step voltage out of the table header. Currently nouveau tried to autodetect this and actually doesn't parse the entries. This Series adds two things: 1. It parses the entries 2. It decides upon a field in the

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.
