Abstract
Systems and methods for waking up waiting processing streams in a manner that reduces the number of spurious wakeups. An example method may comprise: assigning identifiers of a sequence of identifiers to wakeup signals and to processing streams, the sequence of identifiers representing a chronological order that the wakeup signals are initiated and the processing streams begin waiting, wherein each of the identifiers is exclusively assigned to either a wakeup signal or a processing stream and the sequence of identifiers comprises a first identifier associated with a wakeup signal; and responsive to receiving the wakeup signal, avoiding waking a processing stream associated with an identifier greater than the first identifier.
