[PATCH 0/2] Fix some VID parsing in the voltage table version 0x50
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

[PATCH 00/19] Volting/Clocking improvements for Fermi and newer
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

[PATCH v3 00/29] Volting/Clocking improvements for Fermi and newer
This is an updated series for the old clocking improvement one.
I think I got everything needed in place and also a simple update mechanism for
updating the cstates/voltage on temperature changes.
If anything is unclear how I REed or got the information, please leave a note
so that I can provide additional information in the commits.
Besides that I think we are pretty close now and only some

[PATCH v5 00/20] Engine Reclocking Fixes for Fermi-Maxwell2
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

[PATCH v4 00/37] Volting/Clocking improvements for Fermi and newer
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.
