The proposed solution is to have an interface where drivers can

the current global desired maximum.
Nifty (aka "dumb") idea: would it make sense to enable drivers to register a
callback "we're going to go idle now" to e.g. let a driver refill or
service its hardware buffers the very moment before idling?
I could have sworn there was an idle call notifier already\
ah there is on x86-64 but it is architecture specific...
