Module cpu 

Pinned CPU capabilities and scheduler observations.

Structs

CpuLoadSummary

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

CpuLocal

Scheduler state that is created explicitly and mutated only by its owner CPU.

CpuLocalOwnerBorrow

Exclusive owner borrow of one pinned CpuLocal.

CpuRemote

Stable cross-CPU publication endpoint for one scheduler owner.

CpuRemoteHandle

Opaque pointer-sized handle to one Arc-backed remote CPU endpoint.

CpuSnapshot

Stable, allocation-free scheduler state used by deterministic model tests.

CurrentCpuLocalHandle

Opaque address of the current CPU’s pinned owner-only scheduler object.

CurrentCpuOwnerHandles

Runtime-owned capability snapshot for one pinned scheduler CPU.

IrqGuardToken

Token returned by the nested IRQ guard service.

LocalIrqState

Runtime-defined raw local-IRQ state saved by a synchronization guard.

OwnerControlDrain

Result of one bounded owner-control drain.

PreemptGuardToken

Token returned by the nested task-preemption guard service.

RqClockSample

One Linux-style runqueue-clock observation for a target CPU.

RuntimeCpuId

Logical CPU identifier exchanged with the operating-system runtime.

SchedulerDeadlineUpdate

One generation-ordered publication from a CPU’s scheduler owner.

Enums

CpuLifecycleState

Placement and remote-publication state of one logical CPU.

SchedulerRuntimeDeadline

Owner-local update for the current scheduling class’s hrtick.

Functions

current_cpu_needs_resched

Tests the sticky reschedule state of the calling CPU.

current_needs_immediate_scheduler_work_pinned^⚠

Tests only scheduler work consumed by kernel preempt-enable/IRQ return.

current_needs_reschedule_pinned^⚠

Tests the current CPU’s sticky reschedule request while migration is pinned.

idle_current_cpu_once

Executes one lossless idle publication/recheck/WFI iteration.
