In a group, either all events can be scheduled or\nnone are. To schedule each event in, the function calls event_sched_in().\nIn case of error, event_sched_out() is called on each event in the group.\n\nThe problem is that event_sched_out() does not completely cancel the\neffects of event_sched_in(). Furthermore event_sched_out() changes the\nstate of the event as if it had run which is not true is this particular\ncase.\n\nThose inconsistencies impact time tracking fields and may lead to events\nin a group not all reporting the same time_enabled and time_running values.\nThis is demonstrated with the example below:\n\n$ task -eunhalted_core_cycles,baclears,baclears -e unhalted_core_cycles,baclears,baclears sleep 5\n1946101 unhalted_core_cycles (32.85% scaling, ena\u003d829181, run\u003d556827)\n 11423 baclears (32.85% scaling, ena\u003d829181, run\u003d556827)\n 7671 baclears (0.00% scaling, ena\u003d556827, run\u003d556827)\n\n2250443 unhalted_core_cycles (57.83% scaling, ena\u003d962822, run\u003d405995)\n 11705 baclears (57.83% scaling, ena\u003d962822, run\u003d405995)\n 11705 baclears (57.83% scaling, ena\u003d962822, run\u003d405995)\n\nNotice that in the first group, the last baclears event does not\nreport the same timings as its siblings.\n\nThis issue comes from the fact that tstamp_stopped is updated\nby event_sched_out() as if the event had actually run.\n\nTo solve the issue, we must ensure that, in case of error, there is\nno change in the event state whatsoever. That means timings must\nremain as they were when entering group_sched_in().\n\nTo do this we defer updating tstamp_running until we know the\ntransaction succeeded. Therefore, we have split event_sched_in()\nin two parts separating the update to tstamp_running.\n\nSimilarly, in case of error, we do not want to update tstamp_stopped.\nTherefore, we have split event_sched_out() in two parts separating\nthe update to tstamp_stopped.\n\nWith this patch, we now get the following output:\n\n$ task -eunhalted_core_cycles,baclears,baclears -e unhalted_core_cycles,baclears,baclears sleep 5\n2492050 unhalted_core_cycles (71.75% scaling, ena\u003d1093330, run\u003d308841)\n 11243 baclears (71.75% scaling, ena\u003d1093330, run\u003d308841)\n 11243 baclears (71.75% scaling, ena\u003d1093330, run\u003d308841)\n\n1852746 unhalted_core_cycles (0.00% scaling, ena\u003d784489, run\u003d784489)\n 9253 baclears (0.00% scaling, ena\u003d784489, run\u003d784489)\n 9253 baclears (0.00% scaling, ena\u003d784489, run\u003d784489)\n\nNote that the uneven timing between groups is a side effect of\nthe process spending most of its time sleeping, i.e., not enough\nevent rotations (but that\u0027s a separate issue).\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c4cb86b4c.41e9d80a.44e9.3e19@mx.google.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "ba0cef3d149ce4db293c572bf36ed352b11ce7b9", "tree": "af811c141b19286f715d75c564f121aeda40f309", "parents": [ "c530ccd9a1864a44a7ff35826681229ce9f2357a" ], "author": { "name": "Stephane Eranian", "email": "eranian@google.com", "time": "Fri Oct 15 15:15:01 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Oct 18 19:58:48 2010 +0200" }, "message": "perf_events: Fix bogus AMD64 generic TLB events\n\nPERF_COUNT_HW_CACHE_DTLB:READ:MISS had a bogus umask value of 0 which\ncounts nothing.

module_bug_list list corruption race\n\nWith all the recent module loading cleanups, we\u0027ve minimized the code\nthat sits under module_mutex, fixing various deadlocks and making it\npossible to do most of the module loading in parallel.\n\nHowever, that whole conversion totally missed the rather obscure code\nthat adds a new module to the list for BUG() handling. That code was\ndoubly obscure because (a) the code itself lives in lib/bugs.c (for\ndubious reasons) and (b) it gets called from the architecture-specific\n\"module_finalize()\" rather than from generic code.\n\nCalling it from arch-specific code makes no sense what-so-ever to begin\nwith, and is now actively wrong since that code isn\u0027t protected by the\nmodule loading lock any more.\n\nSo this commit moves the \"module_bug_{finalize,cleanup}()\" calls away\nfrom the arch-specific code, and into the generic code - and in the\nprocess protects it with the module_mutex so that the list operations\nare now safe.\n\nFuture fixups:\n - move the module list handling code into kernel/module.c where it\n belongs.\n - get rid of \u0027module_bug_list\u0027 and just use the regular list of modules\n (called \u0027modules\u0027 - imagine that) that we already create and maintain\n for other reasons.\n\nReported-and-tested-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nCc: Adrian Bunk \u003cbunk@kernel.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: stable@kernel.org\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "31e7e931cdc27f76dc68444edc4df1c0d1bfa6cc", "tree": "5185fc3b7286c7a1f4f3eed17fbd8da233d65043", "parents": [ "a947f0f8f7012a5e8689a9cff7209ec6964ec154" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Fri Oct 01 17:35:46 2010 +0100" }, "committer": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Tue Oct 05 13:39:23 2010 +0100" }, "message": "xen: do not initialize PV timers on HVM if !xen_have_vector_callback\n\nif !xen_have_vector_callback do not initialize PV timer unconditionally\nbecause we still don\u0027t know how many cpus are available and if there is\nmore than one we won\u0027t be able to receive the timer interrupts on\ncpu \u003e 0.\n\nThis patch fixes an hang at boot when Xen does not support vector\ncallbacks and the guest has multiple vcpus.\n\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nAcked-by: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\n" }, { "commit": "a947f0f8f7012a5e8689a9cff7209ec6964ec154", "tree": "99063a2381f600fcde0c464690893449dcabb1e8", "parents": [ "899611ee7d373e5eeda08e9a8632684e1ebbbf00" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Mon Oct 04 16:10:06 2010 +0100" }, "committer": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Tue Oct 05 13:37:28 2010 +0100" }, "message": "xen: do not set xenstored_ready before xenbus_probe on hvm\n\nRegister_xenstore_notifier should guarantee that the caller gets\nnotified even if xenstore is already up.\nTherefore we revert \"do not notify callers from\nregister_xenstore_notifier\" and set xenstored_read at the right time for\nPV on HVM guests too.\nIn fact in case of PV on HVM guests xenstored is ready only after the\nplatform pci driver has completed the initialization, so do not set\nxenstored_ready before the call to xenbus_probe().\n\nThis patch fixes a shutdown_event watcher registration bug that causes\n\"xm shutdown\" not to work properly.\n\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nAcked-by: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\n" }, { "commit": "c62f981f9309486ba5546edbb5925f71e441fa65", "tree": "a552e29d26d470349fe561903a1b33d2669583b7", "parents": [ "00e8976200665eec2fa9264d61885b4d1384d4f0" ], "author": { "name": "Andi Kleen", "email": "andi@firstfloor.org", "time": "Fri Oct 01 14:18:47 2010 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 05 09:48:07 2010 +0200" }, "message": "perf, gcc-4.6: Fix set but unused variable\n\nJust dead code I believe.\n\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: andi@firstfloor.org\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "00e8976200665eec2fa9264d61885b4d1384d4f0", "tree": "5554648e4411fcd6909214f71370348567cf4b2d", "parents": [ "540804b5c52065a87d826f7714b18a3ec0b269f9", "0f940cb7d970f4fd569bb5f9f49774422f2ccbee" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 05 09:47:14 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 05 09:47:14 2010 +0200" }, "message": "Merge branch \u0027perf/urgent\u0027 into perf/core\n\nConflicts:\n\ttools/perf/util/ui/browsers/hists.c\n\nMerge reason: fix the conflict and merge in changes for dependent patch.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2f6b3aa7a563d05453c4d73ccf88191aee84333f", "tree": "25e19592cc7f969005ffe46f8d250f55c103967b", "parents": [ "3c06806e690885ce978ef180c8f8b6f8c17fb4b4", "0f69c897f378bf975c519b1d2455c03d06477dfa" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 04 13:35:48 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 04 13:35:48 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/lrg/voltage-2.6\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/lrg/voltage-2.6:\n regulator: max8649 -
