Optimizing Preemptible Read-Copy Update for Low-Power Usage by Avoiding Unnecessary Wakeups |
摘要 |
A technique for low-power detection of a grace period for deferring the destruction of a shared data element until pre-existing references to the data element have been removed. A grace period processing action is implemented that requires a response from a processor that may be running a preemptible reader of said shared data element before further grace period processing can proceed. A power and reader status of the processor is also determined. Grace period processing may proceed despite the absence of a response from the processor if the power and reader status indicates that an actual response from the processor is unnecessary.
