Enum IdlePolicy 

pub(crate) enum IdlePolicy {
    Capacity,
    Wakee,
    Waker,
    Thread,
    Sticky,
}

Wakeup idle-CPU selection policy. Each variant maps to a value of enum idle_policy_type from src/bpf/intf.h.

Variants

Capacity

Capacity-aware waker preference (performance oriented).

Wakee

Keep the wakee on its previous CPU (cache affinity).

Waker

Move the wakee toward the waker CPU (wakeup locality).

Thread

Move the wakee toward the waker CPU only when both are threads of the same task (multi-thread locality).

Sticky

Keep the wakee on its previous CPU, even if system is busy (tail-latency).
