Description

This extension exposes power constraints to the application, allowing it to provide hints for influencing the device’s clock frequency.

These hints are VkQueue state and are persistent across the life of the queue until the app updates or removes the constraint. The kernel combines the constraints across the active queues from all processes to determine the actual clock frequency levels.
