PM_SUSPEND_FREEZE uses system suspend code path, thus we can get\n more power saving from the devices that does not have good RTPM support.\n\nThis state is useful for\n1) platforms that do not have STR, or have a broken STR.\n2) platforms that have an extremely low power idle state,\n which can be used to replace STR.\n\nThe following describes how PM_SUSPEND_FREEZE state works.\n1. echo freeze \u003e /sys/power/state\n2. the processes are frozen.\n3. all the devices are suspended.\n4. all the processors are blocked by a wait queue\n5. all the processors idles and enters (Deep) c-state.\n6. an interrupt fires.\n7. a processor is woken up and handles the irq.\n8. if it is a general event,\n a) the irq handler runs and quites.\n b) goto step 4.\n9. if it is a real wake event, say, power button pressing, keyboard touch, mouse moving,\n a) the irq handler runs and activate the wakeup source\n b) wakeup_source_activate() notifies the wait queue.\n c) system starts resuming from PM_SUSPEND_FREEZE\n10. all the devices are resumed.\n11. all the processes are unfrozen.\n12. system is back to working.\n\nKnown Issue:\nThe wakeup of this new PM_SUSPEND_FREEZE state may behave differently\nfrom the previous suspend state.\nTake ACPI platform for example, there are some GPEs that only enabled\nwhen the system is in sleep state, to wake the system backk from S3/S4.\nBut we are not touching these GPEs during transition to PM_SUSPEND_FREEZE.\nThis means we may lose some wake event.\nBut on the other hand, as we do not disable all the Interrupts during\nPM_SUSPEND_FREEZE, we may get some extra \"wakeup\" Interrupts, that are\nnot available for S3/S4.\n\nThe patches has been tested on an old Sony laptop, and here are the results:\n\nAverage Power:\n1. RPTM/idle for half an hour:\n 14.8W, 12.6W, 14.1W, 12.5W, 14.4W, 13.2W, 12.9W\n2. Freeze for half an hour:\n 11W, 10.4W, 9.4W, 11.3W 10.5W\n3. RTPM/idle for three hours:\n 11.6W\n4. Freeze for three hours:\n 10W\n5. Suspend to Memory:\n 0.5~0.9W\n\nAverage Resume Latency:\n1. RTPM/idle with a black screen: (From pressing keyboard to screen back)\n Less than 0.2s\n2. Freeze: (From pressing power button to screen back)\n 2.50s\n3. Suspend to Memory: (From pressing power button to screen back)\n 4.33s\n\n\u003eFrom the results, we can see that all the platforms should benefit from\nthis patch, even if it does not have Low Power S0.\n\nSigned-off-by: Zhang Rui \u003crui.zhang@intel.com\u003e\nSigned-off-by: Rafael J.

This\nway the potential conflitcs between .suspend_late()/.resume_early()\nand their runtime PM counterparts are still prevented from happening,\nbut the subtle ordering issues related to disabling/enabling runtime\nPM for devices during system suspend/resume are much easier to avoid.\n\nReported-and-tested-by: Jan-Matthias Braun \u003cjan_braun@gmx.net\u003e\nSigned-off-by: Rafael J.

If such a driver happens\nto call pm_runtime_get_sync() during system suspend, after the core\nhas disabled runtime PM, it will get the error code and will decide\nthat the hardware should not be accessed, although this may be a wrong\nconclusion, depending on the state of the device when runtime PM was\ndisabled.\n\nDrivers might work around this problem by using a test like:\n\n ret \u003d pm_runtime_get_sync(dev);\n if (!ret || (ret \u003d\u003d -EACCES \u0026\u0026 driver_private_data(dev)-\u003esuspended)) {\n /* access hardware */\n }\n\nwhere driver_private_data(dev)-\u003esuspended is a flag set by the\ndriver\u0027s .suspend() method (that would have to be added for this\npurpose). However, that potentially would need to be done by multiple\ndrivers which means quite a lot of duplicated code and bloat.\n\nTo avoid that we can use the observation that the core sets\ndev-\u003epower.is_suspended before disabling runtime PM and use that\ninstead of the driver\u0027s private flag. Still, potentially many drivers\nwould need to repeat that same check in quite a few places, so it\u0027s\nbetter to let the core do it.\n\nThen we can be a bit smarter and check whether or not runtime PM was\ndisabled by the core only (disable_depth \u003d\u003d 1) or by someone else in\naddition to the core (disable_depth \u003e 1). In the former case\nrpm_resume() can return 1 if the runtime PM status is RPM_ACTIVE,\nbecause it means the device was active when the core disabled runtime\nPM. In the latter case it should still return -EACCES, because it\nisn\u0027t clear why runtime PM has been disabled.\n\nTested on AM3730/Beagle-xM where a wakeup IRQ firing during the late\nsuspend phase triggers runtime PM activity in the I2C driver since the\nwakeup IRQ is on an I2C-connected PMIC.\n\n[rjw: Modified whitespace to follow the file\u0027s convention.]\n\nSigned-off-by: Kevin Hilman \u003ckhilman@ti.com\u003e\nSigned-off-by: Rafael J.

Thus instead of replicating the fix in both the idle\ndrivers, or in more platform specific idle drivers if needed, the\nmore general cpuidle infrastructure could handle this.\n\nA suspend callback in cpuidle_driver could handle this fix. But\na cpuidle_driver provides only basic functionalities like platform idle\nstate detection capability and mechanisms to support entry and exit\ninto CPU idle states. All other cpuidle functions are found in the\ncpuidle generic infrastructure for good reason that all cpuidle\ndrivers, irrepective of their platforms will support these functions.\n\nOne option therefore would be to register a suspend callback in cpuidle\nwhich handles this fix. This could be called through a PM_SUSPEND_PREPARE\nnotifier. But this is too generic a notfier for a driver to handle.\n\nAlso, ideally the job of cpuidle is not to handle side effects of suspend.\nIt should expose the interfaces which \"handle cpuidle \u0027during\u0027 suspend\"\nor any other operation, which the subsystems call during that respective\noperation.\n\nThe fix demands that during suspend, no cpus should be allowed to enter\ndeep C-states. The interface cpuidle_uninstall_idle_handler() in cpuidle\nensures that. Not just that it also kicks all the cpus which are already\nin idle out of their idle states which was being done during cpu hotplug\nthrough a CPU_DYING_FROZEN callbacks.\n\nNow the question arises about when during suspend should\ncpuidle_uninstall_idle_handler() be called. Since we are dealing with\ndrivers it seems best to call this function during dpm_suspend().\nDelaying the call till dpm_suspend_noirq() does no harm, as long as it is\nbefore cpu_hotplug_begin() to avoid race conditions with cpu hotpulg\noperations. In dpm_suspend_noirq(), it would be wise to place this call\nbefore suspend_device_irqs() to avoid ugly interactions with the same.\n\nAnanlogously, during resume.\n\nReferences:\n[1] https://bugs.launchpad.net/ubuntu/+source/linux/+bug/674075.\n[2] http://marc.info/?l\u003dlinux-pm\u0026m\u003d133958534231884\u0026w\u003d2\n\nReported-and-tested-by: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nSigned-off-by: Preeti U Murthy \u003cpreeti@linux.vnet.ibm.com\u003e\nReviewed-by: Srivatsa S.

Then, power can only be removed from the\ndomain if all I/O devices in it are not in use and the CPU core\nis idle. Add preliminary support for that to the generic PM domains\nframework.\n\nFirst, the platform is expected to provide a cpuidle driver with one\nextra state designated for use with the generic PM domains code.\nThis state should be initially disabled and its exit_latency value\nshould be set to whatever time is needed to bring up the CPU core\nitself after restoring power to it, not including the domain\u0027s\npower on latency. Its .enter() callback should point to a procedure\nthat will remove power from the domain containing the CPU core at\nthe end of the CPU power transition.\n\nThe remaining characteristics of the extra cpuidle state, referred to\nas the \"domain\" cpuidle state below, (e.g. power usage, target\nresidency) should be populated in accordance with the properties of\nthe hardware.\n\nNext, the platform should execute genpd_attach_cpuidle() on the PM\ndomain containing the CPU core. That will cause the generic PM\ndomains framework to treat that domain in a special way such that:\n\n * When all devices in the domain have been suspended and it is about\n to be turned off, the states of the devices will be saved, but\n power will not be removed from the domain. Instead, the \"domain\"\n cpuidle state will be enabled so that power can be removed from\n the domain when the CPU core is idle and the state has been chosen\n as the target by the cpuidle governor.\n\n * When the first I/O device in the domain is resumed and\n __pm_genpd_poweron(() is called for the first time after\n power has been removed from the domain, the \"domain\" cpuidle\n state will be disabled to avoid subsequent surprise power removals\n via cpuidle.\n\nThe effective exit_latency value of the \"domain\" cpuidle state\ndepends on the time needed to bring up the CPU core itself after\nrestoring power to it as well as on the power on latency of the\ndomain containing the CPU core. Thus the \"domain\" cpuidle state\u0027s\nexit_latency has to be recomputed every time the domain\u0027s power on\nlatency is updated, which may happen every time power is restored\nto the domain, if the measured power on latency is greater than\nthe latency stored in the corresponding generic_pm_domain structure.\n\nSigned-off-by: Rafael J.

First,\nintroduce new fields, constraint_changed and max_off_time_changed,\ninto struct gpd_timing_data and struct generic_pm_domain,\nrespectively, and register a PM QoS notifier function when adding\na device into a domain that will set those fields to \u0027true\u0027 whenever\nthe device\u0027s PM QoS constraint is modified. Second, make\ndefault_stop_ok() and default_power_down_ok() use those fields to\ndecide whether or not to carry out their computations from scratch.\n\nThe device and PM domain hierarchies are taken into account in that\nand the expense is that the changes of PM QoS constraints of\nsuspended devices will not be taken into account immediately, which\nisn\u0027t guaranteed anyway in general.\n\nSigned-off-by: Rafael J.
