The broadcast device\nserves as a backup for per cpu timers which stop in deeper\nC-states. To avoid starvation of the cpus which might be in idle and\ndepend on broadcast mode it marks the other cpus as broadcast active\nand sets the brodcast expiry value of those cpus to the next tick.\n\nThe oneshot mode broadcast bit for the other cpus is sticky and gets\nonly cleared when those cpus exit idle. If a cpu was not idle while\nthe bit got set in consequence the bit prevents that the broadcast\ndevice is armed on behalf of that cpu when it enters idle for the\nfirst time after it switched to oneshot mode.\n\nIn most cases that goes unnoticed as one of the other cpus has usually\na timer pending which keeps the broadcast device armed with a short\ntimeout. Now if the only cpu which has a short timer active has the\nbit set then the broadcast device will not be armed on behalf of that\ncpu and will fire way after the expected timer expiry. In the case of\nChristians bug report it took ~145 seconds which is about half of the\nwrap around time of HPET (the limit for that device) due to the fact\nthat all other cpus had no timers armed which expired before the 145\nseconds timeframe.\n\nThe solution is simply to clear the broadcast active bit\nunconditionally when a cpu switches to oneshot mode after the first\ncpu switched the broadcast device over. It\u0027s not idle at that point\notherwise it would not be executing that code.\n\n[ I fundamentally hate that broadcast crap.

There is\nstill the concept of idle load balancer (performing the load balancing\non behalf of all the idle cpu\u0027s in the system). 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. Using that cpu will add more delays to the timers than intended\n(as that cpu\u0027s timer base may not be uptodate wrt jiffies etc). This was\ncausing mysterious slowdowns during boot etc.\n\nFor now, in the semi idle case, use the nearest busy cpu for migrating timers\nfrom an idle cpu.

This is fixed by handling\nthe edge case in update_wall_time().\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nCc: Petr Titěra \u003cP.Titera@century.cz\u003e\nLKML-Reference: \u003c1270589451-30773-1-git-send-email-johnstul@us.ibm.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "c9494727cf293ae2ec66af57547a3e79c724fec2", "tree": "44ae197b64fa7530ee695a90ad31326dda06f1e1", "parents": [ "6427462bfa50f50dc6c088c07037264fcc73eca1", "42be79e37e264557f12860fa4cc84b4de3685954" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 02 20:02:55 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 02 20:03:08 2010 +0200" }, "message": "Merge branch \u0027linus\u0027 into sched/core\n\nMerge reason: update to latest upstream\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "5a0e3ad6af8660be21ca98a971cd00f331318c05", "tree": "5bfb7be11a03176a87296a43ac6647975c00a1d1", "parents": [ "ed391f4ebf8f701d3566423ce8f17e614cde9806" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Wed Mar 24 17:04:11 2010 +0900" }, "committer": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Tue Mar 30 22:02:32 2010 +0900" }, "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" }, { "commit": "e1292ba164742e3a236e407148e00300b7196906", "tree": "67b924190ab7a64a64dad136de45932f8af1a970", "parents": [ "12b8aeee3e51654fb95a3baff2e093f2513bb87d" ], "author": { "name": "John Stultz", "email": "johnstul@us.ibm.com", "time": "Thu Mar 18 20:19:27 2010 -0700" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Mar 23 17:19:37 2010 +0100" }, "message": "ntp: Make time_adjust static\n\nNow that no arches are accessing time_adjust directly,\nmake it static.\n\nSigned-off-by: John Stultz \u003cjohnstul@us.ibm.com\u003e\nLKML-Reference: \u003c1268968769-19209-1-git-send-email-johnstul@us.ibm.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "830ec0458c390f29c6c99e1ff7feab9e36368d12", "tree": "81a344892bd7696a42d87b76189b59f4e1af71ef", "parents": [ "15365c108ea27598e265f8c13e7051d99ca5b0b9" ], "author": { "name": "John Stultz", "email": "johnstul@us.ibm.com", "time": "Thu Mar 18 14:47:30 2010 -0700" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Tue Mar 23 16:41:01 2010 +0100" }, "message": "time: Fix accumulation bug triggered by long delay.\n\nThe logarithmic accumulation done in the timekeeping has some overflow\nprotection that limits the max shift value.
