values decreasing\ndescribed in the thread:\n\n http://lkml.org/lkml/2009/11/3/522\n\nNow cputime is accounted in the following way:\n\n - {u,s}time in task_struct are increased every time when the thread\n is interrupted by a tick (timer interrupt).\n\n - When a thread exits, its {u,s}time are added to signal-\u003e{u,s}time,\n after adjusted by task_times().\n\n - When all threads in a thread_group exits, accumulated {u,s}time\n (and also c{u,s}time) in signal struct are added to c{u,s}time\n in signal struct of the group\u0027s parent.\n\nSo {u,s}time in task struct are \"raw\" tick count, while\n{u,s}time and c{u,s}time in signal struct are \"adjusted\" values.\n\nAnd accounted values are used by:\n\n - task_times(), to get cputime of a thread:\n This function returns adjusted values that originates from raw\n {u,s}time and scaled by sum_exec_runtime that accounted by CFS.\n\n - thread_group_cputime(), to get cputime of a thread group:\n This function returns sum of all {u,s}time of living threads in\n the group, plus {u,s}time in the signal struct that is sum of\n adjusted cputimes of all exited threads belonged to the group.\n\nThe problem is the return value of thread_group_cputime(),\nbecause it is mixed sum of \"raw\" value and \"adjusted\" value:\n\n group\u0027s {u,s}time \u003d foreach(thread){{u,s}time} + exited({u,s}time)\n\nThis misbehavior can break {u,s}time monotonicity.\nAssume that if there is a thread that have raw values greater\nthan adjusted values (e.g. interrupted by 1000Hz ticks 50 times\nbut only runs 45ms) and if it exits, cputime will decrease (e.g.\n-5ms).\n\nTo fix this, we could do:\n\n group\u0027s {u,s}time \u003d foreach(t){task_times(t)} + exited({u,s}time)\n\nBut task_times() contains hard divisions, so applying it for\nevery thread should be avoided.\n\nThis patch fixes the above problem in the following way:\n\n - Modify thread\u0027s exit (\u003d __exit_signal()) not to use task_times().\n It means {u,s}time in signal struct accumulates raw values instead\n of adjusted values. As the result it makes thread_group_cputime()\n to return pure sum of \"raw\" values.\n\n - Introduce a new function thread_group_times(*task, *utime, *stime)\n that converts \"raw\" values of thread_group_cputime() to \"adjusted\"\n values, in same calculation procedure as task_times().\n\n - Modify group\u0027s exit (\u003d wait_task_zombie()) to use this introduced\n thread_group_times(). It make c{u,s}time in signal struct to\n have adjusted values like before this patch.\n\n - Replace some thread_group_cputime() by thread_group_times().\n This replacements are only applied where conveys the \"adjusted\"\n cputime to users, and where already uses task_times() near by it.\n (i.e. sys_times(), getrusage(), and /proc/\u003cPID\u003e/stat.)\n\nThis patch have a positive side effect:\n\n - Before this patch, if a group contains many short-life threads\n (e.g. runs 0.9ms and not interrupted by ticks), the group\u0027s\n cputime could be invisible since thread\u0027s cputime was accumulated\n after adjusted: imagine adjustment function as adj(ticks, runtime),\n {adj(0, 0.9) + adj(0, 0.9) + ....} \u003d {0 + 0 + ....} \u003d 0.\n After this patch it will not happen because the adjustment is\n applied after accumulated.\n\nv2:\n - remove if()s, put new variables into signal_struct.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Spencer Candland \u003cspencer@bluehost.com\u003e\nCc: Americo Wang \u003cxiyou.wangcong@gmail.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Stanislaw Gruszka \u003csgruszka@redhat.com\u003e\nLKML-Reference: \u003c4B162517.8040909@jp.fujitsu.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "d99ca3b977fc5a93141304f571475c2af9e6c1c5", "tree": "7665ebdafcef46c310055021562e6629f59eafd5", "parents": [ "be8147e68625a1adb111acfd6b98a492be4b74d0" ], "author": { "name": "Hidetoshi Seto", "email": "seto.hidetoshi@jp.fujitsu.com", "time": "Wed Dec 02 17:26:47 2009 +0900" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 02 17:32:39 2009 +0100" }, "message": "sched, cputime: Cleanups related to task_times()\n\n- Remove if({u,s}t)s because no one call it with NULL now.\n- Use cputime_{add,sub}().\n- Add ifndef-endif for prev_{u,s}time since they are used\n only when !VIRT_CPU_ACCOUNTING.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Spencer Candland \u003cspencer@bluehost.com\u003e\nCc: Americo Wang \u003cxiyou.wangcong@gmail.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nCc: Stanislaw Gruszka \u003csgruszka@redhat.com\u003e\nLKML-Reference: \u003c4B1624C7.7040302@jp.fujitsu.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "bdddd2963c0264c56f18043f6fa829d3c1d3d1c0", "tree": "b3d886be91ddcf99e3b83c120aedebb840ff75df", "parents": [ "8592e6486a177a02f048567cb928bc3a1f9a86c3" ], "author": { "name": "Rusty Russell", "email": "rusty@rustcorp.com.au", "time": "Wed Dec 02 14:09:16 2009 +1030" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 02 10:27:16 2009 +0100" }, "message": "sched: Fix isolcpus boot option\n\nAnton Blanchard wrote:\n\n\u003e We allocate and zero cpu_isolated_map after the isolcpus\n\u003e __setup option has run.

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming.
