[PATCH 0/3] Expose power budget cap via hwmon
There is an optinal header field in the power budget table we can use to
read out the power cap of the GPU.
We should have this in the kernel before actually using it to catch errors
and see how reliable this is, but as it seems it works on all GPUs as
expected on Kepler und Maxwells with the power cap field set in the vbios.
This series keeps things really simple for now until we figure out

RFC [PATCH 0/3] Expose power budget cap via hwmon
There is an optinal header field in the power budget table we can use to
read out the power cap of the GPU.
Sadly it is optional and if that field isn't sad, things beome
complicated.
Anyhow, this is good enough for most cards and we can use it later for
capping the power consumption of the GPUs, but first, just export those
values through hwmon.
First design, will change stuff, want

[PATCH v4 0/3] Expose power budget cap via hwmon
There is an optinal header field in the power budget table we can use to
read out the power cap of the GPU.
The meaning of this header field was confirmed with nvidia-smi -q:
The rows "Min Power Limit", "Power Limit" and "Max Power Limit" are set
to the "min", "avg" and "max" values from the referenced power budget
entry respectively.
