OPTIMIZING NON-PREEMPTIBLE READ-COPY UPDATE FOR LOW-POWER USAGE BY AVOIDING UNNECESSARY WAKEUPS |
摘要 |
A technique for low-power detection of a grace period following a shared dat a element update operation that affects non-preemptible data readers. A grace period processing action is implemented that requires a processor that may be running a non-preemptible reader of the shared data element to pass through a quiescent state before further grace period processing can proceed. A power status of the processor is also determined. Further grace period processing may proceed without requiring the processor to pass through a quiescent stat e if the power status indicates that quiescent state processing by the processor is unnecessary.
