Method and apparatus for enhancing a hibernate and resume process using user space synchronization

摘要: Before hibernating a computing device (102), system software components (116) are notified of an upcoming hibernation process. The notifications conveyed through application program interface (API) (114). At least portion the can perform one or more pre-hibernation activities to place that component in ready-to-resume state. Each indicates when it is ready for hibernation. Responsive receiving indication from each (116), process complete. completed creates snapshot (122) nonvolatile memory. saves state information (124) (116). (102) be restored after using resume (130), which reads (122).
