"nohz: Fix get_next_timer_interrupt() vs cpu hotplug\n\nThis fixes a bug as seen on 2.6.32 based kernels where timers got\nenqueued on offline cpus.\n\nIf a cpu goes offline it might still have pending timers. These will\nbe migrated during CPU_DEAD handling after the cpu is offline.\nHowever while the cpu is going offline it will schedule the idle task\nwhich will then call tick_nohz_stop_sched_tick().\n\nThat function in turn will call get_next_timer_intterupt() to figure\nout if the tick of the cpu can be stopped or not. If it turns out that\nthe next tick is just one jiffy off (delta_jiffies \u003d\u003d 1)\ntick_nohz_stop_sched_tick() incorrectly assumes that the tick should\nnot stop and takes an early exit and thus it won\u0027t update the load\nbalancer cpu.\n\nJust afterwards the cpu will be killed and the load balancer cpu could\nbe the offline cpu.\n\nOn 2.6.32 based kernel get_nohz_load_balancer() gets called to decide\non which cpu a timer should be enqueued (see __mod_timer()). Which\nleads to the possibility that timers get enqueued on an offline cpu.\nThese will never expire and can cause a system hang.\n\nThis has been observed 2.6.32 kernels. On current kernels\n__mod_timer() uses get_nohz_timer_target() which doesn\u0027t have that\nproblem. However there might be other problems because of the too\nearly exit tick_nohz_stop_sched_tick() in case a cpu goes offline.\n\nThe easiest and probably safest fix seems to be to let\nget_next_timer_interrupt() just lie and let it say there isn\u0027t any\npending timer if the current cpu is offline.\n\nI also thought of moving migrate_[hr]timers() from CPU_DEAD to\nCPU_DYING, but seeing that there already have been fixes at least in\nthe hrtimer code in this area I\u0027m afraid that this could add new\nsubtle bugs.\n\nSigned-off-by: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c20101201091109.GA8984@osiris.boeblingen.de.ibm.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "0f004f5a696a9434b7214d0d3cbd0525ee77d428", "tree": "274b3bb92469789284d864314d46e902c70e8384", "parents": [ "6313e3c21743cc88bb5bd8aa72948ee1e83937b6" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Tue Nov 30 19:48:45 2010 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 08 20:15:04 2010 +0100" }, "message": "sched: Cure more NO_HZ load average woes\n\nThere\u0027s a long-running regression that proved difficult to fix and\nwhich is hitting certain people and is rather annoying in its effects.\n\nDamien reported that after 74f5187ac8 (sched: Cure load average vs\nNO_HZ woes) his load average is unnaturally high, he also noted that\neven with that patch reverted the load avgerage numbers are not\ncorrect.\n\nThe problem is that the previous patch only solved half the NO_HZ\nproblem, it addressed the part of going into NO_HZ mode, not of\ncomming out of NO_HZ mode.

unnecessary.\n\nSince an easy interface to hrtimers could lead to an undesired\nproliferation of interrupts, we provide only a \"range\" API,\nforcing the caller to think about an acceptable tolerance on\nboth ends and hopefully avoiding introducing another interrupt.\n\nINTRO\n\nAs discussed here ( http://lkml.org/lkml/2007/8/3/250 ), msleep(1) is not\nprecise enough for many drivers (yes, sleep precision is an unfair notion,\nbut consistently sleeping for ~an order of magnitude greater than requested\nis worth fixing). This patch adds a usleep API so that udelay does not have\nto be used. Obviously not every udelay can be replaced (those in atomic\ncontexts or being used for simple bitbanging come to mind), but there are\nmany, many examples of\n\nmydriver_write(...)\n/* Wait for hardware to latch */\nudelay(100)\n\nin various drivers where a busy-wait loop is neither beneficial nor\nnecessary, but msleep simply does not provide enough precision and people\nare using a busy-wait loop instead.\n\nCONCERNS FROM THE RFC\n\nWhy is udelay a problem / necessary? Most callers of udelay are in device/\ndriver initialization code, which is serial...\n\n\tAs I see it, there is only benefit to sleeping over a delay; the\n\tnotion of \"refactoring\" areas that use udelay was presented, but\n\tI see usleep as the refactoring. Consider i2c, if the bus is busy,\n\tyou need to wait a bit (say 100us) before trying again, your\n\tcurrent options are:\n\n\t\t* udelay(100)\n\t\t* msleep(1) \u003c-- As noted above, actually as high as ~20ms\n\t\t\t\ton some platforms, so not really an option\n\t\t* Manually set up an hrtimer to try again in 100us (which\n\t\t is what usleep does anyway...)\n\n\tPeople choose the udelay route because it is EASY; we need to\n\tprovide a better easy route.\n\n\tDevice / driver / boot code is *currently* serial, but every few\n\tmonths someone makes noise about parallelizing boot, and IMHO, a\n\tlittle forward-thinking now is one less thing to worry about\n\tif/when that ever happens\n\nudelay\u0027s could be preempted\n\n\tSure, but if udelay plans on looping 1000 times, and it gets\n\tpreempted on loop 200, whenever it\u0027s scheduled again, it is\n\tgoing to do the next 800 loops.\n\nIs the interruptible case needed?\n\n\tProbably not, but I see usleep as a very logical parallel to msleep,\n\tso it made sense to include the \"full\" API. Processors are getting\n\tfaster (albeit not as quickly as they are becoming more parallel),\n\tso if someone wanted to be interruptible for a few usecs, why not\n\tlet them? If this is a contentious point, I\u0027m happy to remove it.\n\nOTHER THOUGHTS\n\nI believe there is also value in exposing the usleep_range option; it gives\nthe scheduler a lot more flexibility and allows the programmer to express\nhis intent much more clearly; it\u0027s something I would hope future driver\nwriters will take advantage of.\n\nTo get the results in the NUMBERS section below, I literally s/udelay/usleep\nthe kernel tree; I had to go in and undo the changes to the USB drivers, but\neverything else booted successfully; I find that extremely telling in and\nof itself -- many people are using a delay API where a sleep will suit them\njust fine.\n\nSOME ATTEMPTS AT NUMBERS\n\nIt turns out that calculating quantifiable benefit on this is challenging,\nso instead I will simply present the current state of things, and I hope\nthis to be sufficient:\n\nHow many udelay calls are there in 2.6.35-rc5?\n\n\tudealy(ARG) \u003e\u003d\t| COUNT\n\t1000\t\t| 319\n\t500\t\t| 414\n\t100\t\t| 1146\n\t20\t\t| 1832\n\nI am working on Android, so that is my focus for this. The following table\nis a modified usleep that simply printk\u0027s the amount of time requested to\nsleep; these tests were run on a kernel with udelay \u003e\u003d 20 --\u003e usleep\n\n\"boot\" is power-on to lock screen\n\"power collapse\" is when the power button is pushed and the device suspends\n\"resume\" is when the power button is pushed and the lock screen is displayed\n (no touchscreen events or anything, just turning on the display)\n\"use device\" is from the unlock swipe to clicking around a bit; there is no\n\tsd card in this phone, so fail loading music, video, camera\n\n\tACTION\t\t| TOTAL NUMBER OF USLEEP CALLS\t| NET TIME (us)\n\tboot\t\t| 22\t\t\t\t| 1250\n\tpower-collapse\t| 9\t\t\t\t| 1200\n\tresume\t\t| 5\t\t\t\t| 500\n\tuse device\t| 59\t\t\t\t| 7700\n\nThe most interesting category to me is the \"use device\" field; 7700us of\nbusy-wait time that could be put towards better responsiveness, or at the\nleast less power usage.\n\nSigned-off-by: Patrick Pannuto \u003cppannuto@codeaurora.org\u003e\nCc: apw@canonical.com\nCc: corbet@lwn.net\nCc: arjan@linux.intel.com\nCc: Randy Dunlap \u003crdunlap@xenotime.net\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "e1b004c3ef9c59db5f013528628b51c8653155ec", "tree": "2c60763d361df84131852c3351c7fc0cd754614d", "parents": [ "af5ab277ded04bd9bc6b048c5a2f0e7d70ef0867" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Aug 04 10:53:00 2010 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Aug 04 10:53:00 2010 +0200" }, "message": "Revert \"timer: Added usleep[_range] timer\"\n\nThis reverts commit 22b8f15c2f7130bb0386f548428df2ffd4e81903 to merge\nan advanced version.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "8cadd2831bf3abc94f4530e7fdbab7bb39b6b27d", "tree": "4027798914cc3213692a4865797898a5ae0a0b49", "parents": [ "81f61484f16decba0fb68400fe0036b337b4cdc7" ], "author": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Mon May 10 14:26:20 2010 -0700" }, "committer": { "name": "Matthew Garrett", "email": "mjg@redhat.com", "time": "Tue Aug 03 09:48:45 2010 -0400" }, "message": "timer: add on-stack deferrable timer interfaces\n\nIn some cases (for instance with kernel threads) it may be desireable to\nuse on-stack deferrable timers to get their power saving benefits.

Busy CPU kicks the nohz\nbalancer when any of the nohz CPUs need idle load balancing.\nThe kickee CPU does the idle load balancing on behalf of all idle CPUs\ninstead of the normal idle balance.\n\nThis addresses the below two problems with the current nohz ilb logic:\n* the idle load balancer continued to have periodic ticks during idle and\n wokeup frequently, even though it did not have any rebalancing to do on\n behalf of any of the idle CPUs.\n* On x86 and CPUs that have APIC timer stoppage on idle CPUs, this\n periodic wakeup can result in a periodic additional interrupt on a CPU\n doing the timer broadcast.\n\nAlso currently we are migrating the unpinned timers from an idle to the cpu\ndoing idle load balancing (when all the cpus in the system are idle,\nthere is no idle load balancing cpu and timers get added to the same idle cpu\nwhere the request was made. So the existing optimization works only on semi idle\nsystem).\n\nAnd In semi idle system, we no longer have periodic ticks on the idle load\nbalancer CPU.

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" }, { "commit": "802702e0c2618465b813242d4dfee6a233ba0beb", "tree": "e21c74065e82a77c45c4f815c626fbafc7fff469", "parents": [ "576da126a6c7364d70dfd58d0bbe43d05cf5859f" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Mar 12 20:13:23 2010 +0100" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Fri Mar 12 22:40:44 2010 +0100" }, "message": "timer: Try to survive timer callback preempt_count leak\n\nIf a timer callback leaks preempt_count we currently assert a\nBUG().
