Session information has not yet been published for this event.
One Line Summary
Can we, and should we unify idle management of CPUs and IO devices
Idle CPUs are managed by the CPUidle framework. Idle IO devices are managed by runtime PM and genpd. Can we unify them?
The goal of this topic is to discuss goals and challenges of using runtime PM and genpd for CPU and cluster idle management.
