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
51 'firmware' - means that the memory image will be saved to disk
55 'platform' - the memory image will be saved by the kernel and
59 'shutdown' - the memory image will be saved by the kernel and
62 'reboot' - the memory image will be saved by the kernel and
65 Additionally, /sys/power/disk can be used to turn on one of the
66 two testing modes of the suspend-to-disk mechanism: 'testproc'
67 or 'test'. If the suspend-to-disk mechanism is in the
68 'testproc' mode, writing 'disk' to /sys/power/state will cause
71 the 'test' mode, writing 'disk' to /sys/power/state will cause
78 The suspend-to-disk method may be chosen by writing to this

203 The /sys/power/autosleep file can be written one of the strings
204 returned by reads from /sys/power/state. If that happens, a

216 What: /sys/power/wake_lock
220 The /sys/power/wake_lock file allows user space to create
221 wakeup source objects and activate them on demand (if one of
223 /sys/power/wakeup_count file block or return false). When a
224 string without white space is written to /sys/power/wake_lock,
225 it will be assumed to represent a wakeup source name. If there
226 is a wakeup source object with that name, it will be activated
227 (unless active already). Otherwise, a new wakeup source object

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