13 The /sys/power/state file controls system sleep states.
15 labels, which may be "mem" (suspend), "standby" (power-on
16 suspend), "freeze" (suspend-to-idle) and "disk" (hibernation).

42 What: /sys/power/disk
46 The /sys/power/disk file controls the operating mode of the
47 suspend-to-disk mechanism. Reading from this file returns
50 'firmware' - means that the memory image will be saved to disk
53 'platform' - the memory image will be saved by the kernel and
56 'shutdown' - the memory image will be saved by the kernel and
58 'reboot' - the memory image will be saved by the kernel and
61 Additionally, /sys/power/disk can be used to turn on one of the
62 two testing modes of the suspend-to-disk mechanism: 'testproc'
63 or 'test'. If the suspend-to-disk mechanism is in the
64 'testproc' mode, writing 'disk' to /sys/power/state will cause
67 the 'test' mode, writing 'disk' to /sys/power/state will cause
74 The suspend-to-disk method may be chosen by writing to this
87 What: /sys/power/image_size
91 The /sys/power/image_size file controls the size of the image
92 created by the suspend-to-disk mechanism. It can be written a
93 string representing a non-negative integer that will be used
95 suspend-to-disk code will do its best to ensure the image size

195 What: /sys/power/autosleep
199 The /sys/power/autosleep file can be written one of the strings
200 returned by reads from /sys/power/state. If that happens, a
207 writes "off" to /sys/power/autosleep.
212 What: /sys/power/wake_lock
216 The /sys/power/wake_lock file allows user space to create
217 wakeup source objects and activate them on demand (if one of
219 /sys/power/wakeup_count file block or return false). When a
220 string without white space is written to /sys/power/wake_lock,
221 it will be assumed to represent a wakeup source name. If there
222 is a wakeup source object with that name, it will be activated
223 (unless active already). Otherwise, a new wakeup source object

231 set regardless of the current state of the wakeup source object
239 What: /sys/power/wake_unlock
243 The /sys/power/wake_unlock file allows user space to deactivate
244 wakeup sources created with the help of /sys/power/wake_lock.
245 When a string is written to /sys/power/wake_unlock, it will be
246 assumed to represent the name of a wakeup source to deactivate.
