Capacity-Aware Superset Scheduler

The CASS scheduler (Capacity-Aware Superset Scheduler) works by selecting the best CPU or CPU cluster (superset) for a task based on the performance capacity of each cluster and the current load on its CPUs. Instead of looking at individual cores alone, it evaluates entire supersets to determine which group can handle the task most efficiently, balancing performance and power consumption. It then chooses an idle CPU within that chosen superset that can execute the task immediately, aiming to improve responsiveness while avoiding inefficient task placement. This approach helps reduce UI lag and boost overall scheduling efficiency, especially on big.LITTLE or DynamIQ mobile processors.
