Module service

Expand description

Scheduler timer, deferred work and reclamation services.

Structs§

ClaimedSchedulerDeadlines: Scheduler-owned deadlines claimed by one physical clockevent firing.
DeferredTaskWorkBatch: One bounded pass performed by the dedicated task-work service thread.
ExpiredTaskDeadline: Allocation-free task expiration copied into caller-owned IRQ storage.
OwnedThreadReapError: Failure returned by TaskSystem::reap_thread_handle.
SchedulerTickCpuTime: IRQ-safe tick-sampled user/system CPU time for one scheduler thread.
SchedulerTickCpuTimeSnapshot: Coherent-enough raw totals from independent monotonic tick counters.
SchedulerTickGate: Shared process or subsystem interest in scheduler-tick task work.
SchedulerTickStamp: Opaque owner-rq sample required to publish one periodic scheduler tick.
TaskClockEventOutcome: Bounded task-clockevent result consumed by the runtime clockevent owner.
TaskDeadlineExpireBatch: Result of one bounded timer-IRQ pass.
TaskDeadlineExpireRequest: Bounded timer-IRQ expiration request.
TaskDeadlineNode: Task-deadline node embedded in one generation-checked scheduler thread.
TaskDeadlineQueue: Fixed-capacity value heap created during CPU-local initialization.
TaskDeadlineRegistration: Move-only ownership of one physical task-deadline queue registration.
TaskDeadlineToken: Node identity and generation identifying one task-deadline arm operation.

SchedulerTickMode: Execution mode sampled by the periodic scheduler tick.
SchedulerTickWorkDisposition: Task-context callback selected by one scheduler-tick publication.
TaskDeadlineError: Failure returned while arming a fixed-capacity timer.
TaskDeadlineKind: Scheduler-owned meaning of one task deadline.

on_clock_event: Performs one bounded task-clockevent pass without allocation or callbacks.
publish_scheduler_tick: Samples CPU time and publishes extension work for a periodic scheduler tick already accounted by on_clock_event.
start_current_ktimer_service: Creates the current CPU’s shutdown-lifetime soft-timer worker.
start_deferred_task_work_service: Creates the shutdown-lifetime service thread for callbacks and reclamation.
