[PATCH 5/9] drm/nouveau/bios/power_budget: Move an expression into a macro call parameter in nvbios_power_budget_header()
Date: Sat, 15 Apr 2023 22:30:30 +0200
The address of a data structure member was determined before
a corresponding null pointer check in the implementation of
the function ?nvbios_power_budget_header?.
Thus avoid the risk for undefined behaviour by moving the usage
of an expression into a parameter for a macro call in one if branch.
This issue was detected by using the Coccinelle software.

[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

[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.
