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

This series does some refactoring in the GK20A's volt and clk drivers (fixing a few things while we are at it) to let GM20B benefit from the GK20A's logic with which it is compatible. GM20B is capable of more sophisticated (and power-efficient) reclocking which will follow later. Even after this more fancy reclocking is merged, the present logic will remain used in the lowest speedo of

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

this series solves different issues we encounter on kepler cards while reclocking: 1. core clock doesn't change at all and produces a volting error (patch 1) this can happen when the voltage table has only 0ed values in the header so we have to parse the entries itself, which contain the right voltages 2. kepler won't clock to highest cstates (patch 2) this happens, because there are
