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. Why the heck thought some\n folks that when going into deep idle it\u0027s a brilliant concept to\n switch off the last device which brings the cpu back from that\n state? ]\n\nThanks to Christian for providing all the valuable debug information!\n\nReported-and-tested-by: Christian Hoffmann \u003cemail@christianhoffmann.info\u003e\nCc: John Stultz \u003cjohnstul@us.ibm.com\u003e\nLink: http://lkml.kernel.org/r/%3Calpine.LFD.2.02.1105161105170.3078%40ionos%3E\nCc: stable@kernel.org\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "47a150edc2ae734c0f4bf50aa19499e23b9a46f8", "tree": "beeba9befd531285f663559a76f6f0f7378a6c2b", "parents": [ "381e7863d94891035a1a6b7836e9db72f9f1cba1" ], "author": { "name": "Serge E.

While not entirely correct this\nworked because hrtimer_init() only accessed statically initialized\ndata (hrtimer_bases.clock_base[CLOCK_MONOTONIC])\n\nCommit e06383db9 (hrtimers: extend hrtimer base code to handle more\nthen 2 clockids) added an indirection to the hrtimer_bases.clock_base\nlookup to avoid gap handling in the hot path. The table which is used\nfor the translataion from CLOCK_ID to HRTIMER_BASE index is\ninitialized at runtime in hrtimers_init(). So the early call of the\nscheduler code translates CLOCK_MONOTONIC to HRTIMER_BASE_REALTIME.\n\nThus the rt_bandwith timer ends up on CLOCK_REALTIME. If the timer is\narmed and the wall clock time is set (e.g. ntpdate in the early boot\nprocess - which also gives the problem deterministic behaviour\ni.e. magic recovery after N hours), then the timer ends up with an\nexpiry time far into the future. That breaks the RT throttler\nmechanism as rt runtime is accumulated and never cleared, so the rt\nthrottler detects a false cpu hog condition and blocks all RT tasks\nuntil the timer finally expires.

This\nwill cause erroneous imbalance calculation.\n\nThe reason is that calculate_imbalance() sees sds-\u003eavg_load \u003d 0 and it\nwill dump entire sds-\u003emax_load into imbalance variable, which is used\nlater on to migrate entire load from busiest CPU to the puller CPU.\n\nThis has two really bad effect:\n\n1. stampede of task migration, and they won\u0027t be able to break out\n of the bad state because of positive feedback loop: large load\n delta -\u003e heavier load migration -\u003e larger imbalance and the cycle\n goes on.\n\n2. severe imbalance in CPU queue depth. This causes really long\n scheduling latency blip which affects badly on application that\n has tight latency requirement.\n\nThe fix is to have kernel calculate domain avg_load in both cases. This\nwill ensure that imbalance calculation is always sensible and the target\nis usually half way between busiest and puller CPU.\n\nSigned-off-by: Ken Chen \u003ckenchen@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: \u003cstable@kernel.org\u003e\nLink: http://lkml.kernel.org/r/20110408002322.3A0D812217F@elm.corp.google.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "e566b76ed30768140df8f0023904aed5a41244f7", "tree": "5d8fa756453cb6f60554c6c253a3cf2a01945628", "parents": [ "621d26567fd0c222f419e3b5ddf39e529e0fdcb3" ], "author": { "name": "Stephane Eranian", "email": "eranian@google.com", "time": "Wed Apr 06 02:54:54 2011 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Apr 11 11:07:55 2011 +0200" }, "message": "perf_event: Fix cgrp event scheduling bug in perf_enable_on_exec()\n\nThere is a bug in perf_event_enable_on_exec() when cgroup events are\nactive on a CPU: the cgroup events may be scheduled twice causing event\nstate corruptions which eventually may lead to kernel panics.\n\nThe reason is that the function needs to first schedule out the cgroup\nevents, just like for the per-thread events.
