Subject: [RFC][PATCH 6/8] PM / Sleep: Implement opportunistic sleep
Date: Tue, 7 Feb 2012 02:06:01 +0100 [thread overview]
Message-ID: <201202070206.01541.rjw@sisk.pl> (raw)
In-Reply-To: <201202070200.55505.rjw@sisk.pl>
From: Rafael J. Wysocki <rjw@sisk.pl>
Introduce a mechanism by which the kernel can trigger global
transitions to a sleep state chosen by user space if there are no
active wakeup sources.
It consists of a new sysfs attribute, /sys/power/autosleep, that
can be written one of the strings returned by reads from
/sys/power/state, a freezable ordered workqueue and a work item
carrying out the "suspend" operations. If a string representing
the system's sleep state is written to /sys/power/autosleep, the
work item triggering transitions to that state is queued up and
it requeues it self after every execution until user space writes
"off" to /sys/power/autosleep. That work item enables the detection
of wakeup events using the functions already defined in
drivers/base/power/wakeup.c (with one small modification) and calls
either pm_suspend(), or hibernate() to put the system into a sleep
state. If a wakeup event is reported while the transition is in
progress, it will abort the transition and the "system suspend" work
item will be queued up again.
