AMD "Automatic Mode Transition" Comes For Lenovo ThinkPad Laptops With Linux 6.0

Just as a note - I don't recommend testing this with the X13 as it's not supported on this generation; Please wait for the next generation of platforms

Good to know, wasn't clear from the commit message if it worked with current platforms or not... I had tried with Linux 6.0 Git the other day on the X13 Gen3 and wasn't detected, so then was guessing as much. Good to see Lenovo prepping early for next-gen!

It seems like Schedutil is great on paper but I haven't yet seen it really compete on any metric vs other schedulers. Maybe I just haven't looked at the right data or my memory is dated.

It really does sound great on paper, but in reality ... just take a look for yourself:

Hopefully this "Automatic Mode Transition" is able to make some smart choices.

But if schedutil as a "smart" CPU governor is anything to go by, I have my doubts here aswell...
