Struct CpuLoadSummary 

pub struct CpuLoadSummary { /* private fields */ }

Allocation-free lockless hints used by remote placement and balancing.

Implementations

impl CpuLoadSummary

pub const fn queued_count(self) -> usize

Returns candidates available to pick_next_task(), excluding current.

pub const fn nr_running(self) -> usize

Returns Linux rq->nr_running, including a non-idle current task.

pub const fn fair_demand(self) -> u64

Returns the Linux nice-weighted Fair demand owned by this CPU.

pub const fn workload_demand(self) -> u64

Returns instantaneous scheduling demand in normal-nice weight units.

Fair work contributes its exact nice weight. RT and Deadline work each contribute one normal-nice capacity unit until class-specific utilization tracking is available.

pub const fn current_workload_demand(self) -> u64

Returns the demand contributed by this CPU’s non-idle current task.

pub const fn has_pushable_fair(self) -> bool

Reports whether this CPU has migratable Fair work.

RT and Deadline overload are deliberately absent from this load snapshot. Their sole remote authority is the root-domain rto/dlo index, matching Linux’s separation between sched-domain load and priority-class overload state.

pub const fn fair_idle_only(self) -> bool

Reports whether every runnable task on this CPU uses SCHED_IDLE.

Mirrors Linux sched_idle_rq(): a non-idle Fair wakee may treat this rq as an idle placement target.

pub const fn fair_delayed_count(self) -> usize

Returns Linux cfs_rq->h_nr_delayed for this flat runqueue.
