It may be disabled by writing "0" to this file, in which case all devices will be suspended and resumed synchronously. + +What: /sys/power/wakeup_count +Date: July 2010 +Contact: Rafael J. Wysocki <rjw@sisk.pl> +Description: + The /sys/power/wakeup_count file allows user space to put the + system into a sleep state while taking into account the + concurrent arrival of wakeup events. Reading from it returns + the current number of registered wakeup events and it blocks if + some wakeup events are being processed at the time the file is + read from. Writing to it will only succeed if the current + number of wakeup events is equal to the written value and, if + successful, will make the kernel abort a subsequent transition + to a sleep state if any wakeup events are reported after the + write has returned. |
