Description
Since last LPC in Vienna, we have continued to explore how to add support for multiple system-wide low power-states to the Linux kernel. A series [1] has been posted that suggests us to add a user-space interface, to allow a system-wakeup latency constraint to be specified. The series also includes deployment for how the latency-constraint can be taken into account during s2idle and especially in regards to CPU/CPU-cluster wakeup-latencies for low-power states.
Let's discuss and try to conclude how to move forward!
