Hello,
wiki says that devices may not support PCI Runtime Power Management. (https://wiki.archlinux.org/title/Power_ … Management) However, I can't seem to find any documentation/list on what devices do and what don't.
Questions:
1. Is there such a list?
2. Is the setting worth it for power saving?
If 2):
2a. Is there a rule of things I should not turn PCIRPM on for?
2b. Is it basically experimentation?
Thank you for reading.

UPDATE: While I have not found a list, I have installed powertop and used --auto-tune to look at what powertop turns on/off by default... Turns out, powertop just makes every single optimization on my device and I seem to not have any problems. Therefore, I'll just make it persistent and wait for issues to arise.
