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 contains a lot of groundwork to finally fix reclocking issues on Kepler+ gpus. There shouldn't be any functional changes with the first patch being the only exception (fixes some voltage table parsing issues with of few kepler gpus) The most interessting thing is the tool in the last patch, which can be ran alongside the nvidia driver to test nouveaus volting code and print 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
