Subject: RFC [PATCH 0/3] Expose power budget cap via hwmon
Date: Mon, 24 Oct 2016 23:11:10 +0200 [thread overview]
Message-ID: <20161024211113.5876-1-karolherbst@gmail.com> (raw)
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 comments. Thanks.

nvbios/power_budget: Add basic power budget parsing
subdev/iccsense: Parse max and crit power level
hwmon: expose power_max and power_crit
