WAKE-UP ORDERING OF PROCESSING STREAMS USING SEQUENTIAL IDENTIFIERS
First Claim
Patent Images
1. A method comprising:
- assigning a first identifier of a sequence of identifiers to a processing stream in a waiting state;
receiving a wakeup signal associated with a second identifier of the sequence of identifiers;
comparing, by a processing device, the first identifier with the second identifier; and
waking the processing stream responsive to determining, in view of comparing, that the processing stream began waiting prior to an initiation of the wakeup signal.

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 a first identifier of a sequence of identifiers to a processing stream in a waiting state; receiving a wakeup signal associated with a second identifier of the sequence of identifiers; comparing, by a processing device, the first identifier with the second identifier; and waking the processing stream responsive to determining, in view of comparing, that the processing stream began waiting prior to an initiation of the wakeup signal.

13. A system comprising:
-
a memory; and a processing device communicably coupled to the memory, the processing device to execute instructions to; assign a first identifier of a sequence of identifiers to a processing stream in a waiting state; receive a wakeup signal associated with a second identifier of the sequence of identifiers; compare, by a processing device, the first identifier with the second identifier; and wake the processing stream responsive to determining, in view of comparing, that the processing stream began waiting prior to an initiation of the wakeup signal.

17. A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to execute operations comprising:
-
assign a first identifier of a sequence of identifiers to a processing stream in a waiting state; receive a wakeup signal associated with a second identifier of the sequence of identifiers; compare, by a processing device, the first identifier with the second identifier; and wake the processing stream responsive to determining, in view of comparing, that the processing stream began waiting prior to an initiation of the wakeup signal.
