First, if a wakeup\nevent occurs exactly when /sys/power/state is being written to, it\nmay be delivered to user space right before the freezer kicks in, so\nthe user space consumer of the event may not be able to process it\nbefore the system is suspended. Second, if a wakeup event occurs\nafter user space has been frozen, it is not generally guaranteed that\nthe ongoing transition of the system into a sleep state will be\naborted.\n\nTo address these issues introduce a new global sysfs attribute,\n/sys/power/wakeup_count, associated with a running counter of wakeup\nevents and three helper functions, pm_stay_awake(), pm_relax(), and\npm_wakeup_event(), that may be used by kernel subsystems to control\nthe behavior of this attribute and to request the PM core to abort\nsystem transitions into a sleep state already in progress.\n\nThe /sys/power/wakeup_count file may be read from or written to by\nuser space. Reads will always succeed (unless interrupted by a\nsignal) and return the current value of the wakeup events counter.\nWrites, however, will only succeed if the written number is equal to\nthe current value of the wakeup events counter. If a write is\nsuccessful, it will cause the kernel to save the current value of the\nwakeup events counter and to abort the subsequent system transition\ninto a sleep state if any wakeup events are reported after the write\nhas returned.\n\n[The assumption is that before writing to /sys/power/state user space\nwill first read from /sys/power/wakeup_count. Next, user space\nconsumers of wakeup events will have a chance to acknowledge or\nveto the upcoming system transition to a sleep state. Finally, if\nthe transition is allowed to proceed, /sys/power/wakeup_count will\nbe written to and if that succeeds, /sys/power/state will be written\nto as well. Still, if any wakeup events are reported to the PM core\nby kernel subsystems after that point, the transition will be\naborted.]\n\nAdditionally, put a wakeup events counter into struct dev_pm_info and\nmake these per-device wakeup event counters available via sysfs,\nso that it\u0027s possible to check the activity of various wakeup event\nsources within the kernel.\n\nTo illustrate how subsystems can use pm_wakeup_event(), make the\nlow-level PCI runtime PM wakeup-handling code use it.\n\nSigned-off-by: Rafael J.

However,\nthere are dependencies between devices such that we\u0027re not allowed\nto suspend the parent of a device before suspending the device\nitself. Analogously, we\u0027re not allowed to resume a device before\nresuming its parent.\n\nThe most straightforward way to take these dependencies into accout\nis to start the async threads used for suspending and resuming\ndevices at the core level, so that async_schedule() is called for\neach suspend and resume callback supposed to be executed\nasynchronously.\n\nFor this purpose, introduce a new device flag, power.async_suspend,\nused to mark the devices whose suspend and resume callbacks are to be\nexecuted asynchronously (ie. in parallel with the main suspend/resume\nthread and possibly in parallel with each other) and helper function\ndevice_enable_async_suspend() allowing one to set power.async_suspend\nfor given device (power.async_suspend is unset by default for all\ndevices). For each device with the power.async_suspend flag set the\nPM core will use async_schedule() to execute its suspend and resume\ncallbacks.\n\nThe async threads started for different devices as a result of\ncalling async_schedule() are synchronized with each other and with\nthe main suspend/resume thread with the help of completions, in the\nfollowing way:\n(1) There is a completion, power.completion, for each device object.\n(2) Each device\u0027s completion is reset before calling async_schedule()\n for the device or, in the case of devices with the\n power.async_suspend flags unset, before executing the device\u0027s\n suspend and resume callbacks.\n(3) During suspend, right before running the bus type, device type\n and device class suspend callbacks for the device, the PM core\n waits for the completions of all the device\u0027s children to be\n completed.\n(4) During resume, right before running the bus type, device type and\n device class resume callbacks for the device, the PM core waits\n for the completion of the device\u0027s parent to be completed.\n(5) The PM core completes power.completion for each device right\n after the bus type, device type and device class suspend (or\n resume) callbacks executed for the device have returned.\n\nSigned-off-by: Rafael J.

This has been requested for multiple\ntimes by many people, including Linus himself, and the reason is that\nwithin the current scheme if -\u003eresume() is called, for example, it\u0027s\ndifficult to say why it\u0027s been called (ie. is it a resume from RAM or\nfrom hibernation or a suspend/hibernation failure etc.?).\n\nThe second purpose is to make the suspend/hibernation callbacks more\nflexible so that device drivers can handle more than they can within\nthe current scheme. For example, some drivers may need to prevent\nnew children of the device from being registered before their\n-\u003esuspend() callbacks are executed or they may want to carry out some\noperations requiring the availability of some other devices, not\ndirectly bound via the parent-child relationship, in order to prepare\nfor the execution of -\u003esuspend(), etc.\n\nUltimately, we\u0027d like to stop using the freezing of tasks for suspend\nand therefore the drivers\u0027 suspend/hibernation code will have to take\ncare of the handling of the user space during suspend/hibernation.\nThat, in turn, would be difficult within the current scheme, without\nthe new -\u003eprepare() and -\u003ecomplete() callbacks.\n\nSigned-off-by: Rafael J.
