Description

Optimizing suspend/resume time makes a significant difference for UX
and power savings. Especially for wearable devices which typically
have small CPUs and small batteries. This talk will point out all the
gaps we've found so far and what we could do to address them and some
of my TODOs to get there.

  • Optimizing global async suspend/resume
  • Using runtime PM to avoid resume/suspend work for short wakeups.
  • s2idle with older PSCI calls?
