Configurations created for real time applications mostly disable power management completely to avoid any impact on latency. It is however, possible to enable power management to a degree to which the impact on latency is tolerable based on application requirements. This presentation addresses how CPU idle states can be enabled and tuned to allow power savings while running real time applications.

The presentation will give a background of the issues faced by real-time applications when CPU power management is enabled. It will then explain tools, configurations and methods that can be used to tune applications and CPU power management in the kernel to be able to save power without impacting the deterministic latency tolerance requirements.
