There are visible glitches and when left for a longer time Nouveau seems to crash. T...

Trello: https://trello.com/c/admzDRvd/50-reduce-performance-refuse-to-boot-if-not-all-the-power-connectors-are-plugged Fixed commit messages. Mark Menzynski (4): bios/gpio: sort gpios by values gpio: fail if gpu external power is missing gpio: check the gpio function 16 in the power check as well gpio: check function 76 in the power check as well

Added config override for power checks.

Please add a config override to skip this, since we'll invariably get it wrong for some setup, and should be able to provide users with workarounds while the issue is being worked out.

...s not being able to set higher clocks. When changing this value Nvidia driver still appeared to ignore it, and I wasn't able to find out why, thus the code is ignoring the value if it is zero.

...ps we shouldn't limit this to a warning (which people tend to report) for a while first too. Also, what's NV's behaviour here? Do they refuse to load, or do they do something like force the GPU into its lowest pstate?
