Comparing with PC/notebook,\na mobile enters/exits suspend-2-ram (we call it s3 on Medfield) far\nmore frequently. If it can\u0027t enter suspend-2-ram in time, the power\nmight be used up soon.\n\nWe often find sometimes, a device suspend fails. Then, system retries\ns3 over and over again. As display is off, testers and developers\ndon\u0027t know what happens.\n\nSome testers and developers complain they don\u0027t know if system\ntries suspend-2-ram, and what device fails to suspend. They need\nsuch info for a quick check. The patch adds suspend_stats under\ndebugfs for users to check suspend to RAM statistics quickly.\n\nIf not using this patch, we have other methods to get info about\nwhat device fails. One is to turn on  CONFIG_PM_DEBUG, but users\nwould get too much info and testers need recompile the system.\n\nIn addition, dynamic debug is another good tool to dump debug info.\nBut it still doesn\u0027t match our utilization scenario closely.\n1) user need write a user space parser to process the syslog output;\n2) Our testing scenario is we leave the mobile for at least hours.\n   Then, check its status. No serial console available during the\n   testing. One is because console would be suspended, and the other\n   is serial console connecting with spi or HSU devices would consume\n   power. These devices are powered off at suspend-2-ram.\n\nSigned-off-by: ShuoX Liu \u003cshuox.liu@intel.com\u003e\nSigned-off-by: Rafael J. Wysocki \u003crjw@sisk.pl\u003e\n"

      "message": "PM / Suspend: Add .suspend_again() callback to suspend_ops\n\nA system or a device may need to control suspend/wakeup events. It may\nwant to wakeup the system after a predefined amount of time or at a\npredefined event decided while entering suspend for polling or delayed\nwork. Then, it may want to enter suspend again if its predefined wakeup\ncondition is the only wakeup reason and there is no outstanding events;\nthus, it does not wakeup the userspace unnecessary or unnecessary\ndevices and keeps suspended as long as possible (saving the power).\n\nEnabling a system to wakeup after a specified time can be easily\nachieved by using RTC. However, to enter suspend again immediately\nwithout invoking userland and unrelated devices, we need additional\nfeatures in the suspend framework.\n\nSuch need comes from:\n\n 1. Monitoring a critical device status without interrupts that can\nwakeup the system. (in-suspend polling)\n An example is ambient temperature monitoring that needs to shut down\nthe system or a specific device function if it is too hot or cold. The\ntemperature of a specific device may be needed to be monitored as well;\ne.g., a charger monitors battery temperature in order to stop charging\nif overheated.\n\n 2. Execute critical \"delayed work\" at suspend.\n A driver or a system/board may have a delayed work (or any similar\nthings) that it wants to execute at the requested time.\n For example, some chargers want to check the battery voltage some\ntime (e.g., 30 seconds) after the battery is fully charged and the\ncharger has stopped. Then, the charger restarts charging if the voltage\nhas dropped more than a threshold, which is smaller than \"restart-charger\"\nvoltage, which is a threshold to restart charging regardless of the\ntime passed.\n\nThis patch allows to add \"suspend_again\" callback at struct\nplatform_suspend_ops and let the \"suspend_again\" callback return true if\nthe system is required to enter suspend again after the current instance\nof wakeup. Device-wise suspend_again implemented at dev_pm_ops or\nsyscore is not done because: a) suspend_again feature is usually under\nplatform-wise decision and controls the behavior of the whole platform\nand b) There are very limited devices related to the usage cases of\nsuspend_again; chargers and temperature sensors are mentioned so far.\n\nWith suspend_again callback registered at struct platform_suspend_ops\nsuspend_ops in kernel/power/suspend.c with suspend_set_ops by the\nplatform, the suspend framework tries to enter suspend again by\nlooping suspend_enter() if suspend_again has returned true and there has\nbeen no errors in the suspending sequence or pending wakeups (by\npm_wakeup_pending).\n\nTested at Exynos4-NURI.\n\n[rjw: Fixed up kerneldoc comment for suspend_enter().]\n\nSigned-off-by: MyungJoo Ham \u003cmyungjoo.ham@samsung.com\u003e\nSigned-off-by: Kyungmin Park \u003ckyungmin.park@samsung.com\u003e\nAcked-by: Pavel Machek \u003cpavel@ucw.cz\u003e\nSigned-off-by: Rafael J.

      "message": "PM / Hibernate: Fix memory corruption related to swap\n\nThere is a problem that swap pages allocated before the creation of\na hibernation image can be released and used for storing the contents\nof different memory pages while the image is being saved.  Since the\nkernel stored in the image doesn\u0027t know of that, it causes memory\ncorruption to occur after resume from hibernation, especially on\nsystems with relatively small RAM that need to swap often.\n\nThis issue can be addressed by keeping the GFP_IOFS bits clear\nin gfp_allowed_mask during the entire hibernation, including the\nsaving of the image, until the system is finally turned off or\nthe hibernation is aborted.  Unfortunately, for this purpose\nit\u0027s necessary to rework the way in which the hibernate and\nsuspend code manipulates gfp_allowed_mask.\n\nThis change is based on an earlier patch from Hugh Dickins.\n\nSigned-off-by: Rafael J.

      "message": "PM: Make it possible to avoid races between wakeup and system sleep\n\nOne of the arguments during the suspend blockers discussion was that\nthe mainline kernel didn\u0027t contain any mechanisms making it possible\nto avoid races between wakeup and system suspend.\n\nGenerally, there are two problems in that area.  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.

      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability.  As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n  http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n  only the necessary includes are there.  ie. if only gfp is used,\n  gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n  blocks and try to put the new include such that its order conforms\n  to its surrounding.  It\u0027s put in the include block which contains\n  core kernel includes, in the same order that the rest are ordered -\n  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n  doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n  because the file doesn\u0027t have fitting include block), it prints out\n  an error message indicating which .h file needs to be added to the\n  file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n   over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n   and ~3000 slab.h inclusions.  The script emitted errors for ~400\n   files.\n\n2. Each error was manually checked.  Some didn\u0027t need the inclusion,\n   some needed manual addition while adding it to implementation .h or\n   embedding .c file was more appropriate for others.  This step added\n   inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n   from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n   e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n   APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n   editing them as sprinkling gfp.h and slab.h inclusions around .h\n   files could easily lead to inclusion dependency hell.  Most gfp.h\n   inclusion directives were ignored as stuff from gfp.h was usually\n   wildly available and often used in preprocessor macros.  Each\n   slab.h inclusion directive was examined and added manually as\n   necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my\n   distributed build env didn\u0027t work with gcov compiles) and a few\n   more options had to be turned off depending on archs to make things\n   build (like ipr on powerpc/64 which failed due to missing writeq).\n\n   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n   * powerpc and powerpc64 SMP allmodconfig\n   * sparc and sparc64 SMP allmodconfig\n   * ia64 SMP allmodconfig\n   * s390 SMP allmodconfig\n   * alpha SMP allmodconfig\n   * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n   a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n"
