I noticed on the Dell XPS 13 9360 some devices do not have power management
enabled by default. From PowerTOP:
Bad Runtime PM for PCI Device Intel Corporation Sunrise Point-LP PCI Express Root Port #1
Bad Runtime PM for PCI Device Intel Corporation Sunrise Point-LP LPC Controller
I don't know what this "Bad" is based on, so I don't know where to
look for something Linux might be doing. I don't see any code that
mentions 9d10 or 9d58 Device IDs in relation to power.
Turns out that PowerTOP marks all devices as *Bad* where `power/control` differs from `auto`. In this case these are set to `on`, which should be good from a power
management perspective.
ok just fixed this in powertop git
thanks for the report!
