Dear Linux folks,
I wonder what C-States I can expect, when connecting a USB-C adapter to
a laptop, like Dell DA300 to my Intel Kaby Lake laptop Dell XPS 13 9360.
My tests with Linux 6.10.0-rc4 show, that with
$ echo 8 | sudo tee /sys/kernel/debug/pmc_core/ltr_ignore
– otherwise only PC8 seems to be reached – I get:
### Dell DA300 connected (to only USB-C port on the left) with Ethernet
cable connected
PC6 is reached:

Sometimes I have reached PC10 already, but no idea if I had something
connected before.
### Dell DA300 connected (to only USB-C port on the left) with nothing
connected to the adapter
PC6 is reached:

Does it depend on the adapter, or is it not possible to reach lower
states than PC6 with something plugged in?
Kind regards,
Paul
