{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": "fa1452e808732ae10e8b1267fd75fc2d028d634b", "tree": "c6c3031fa072b168fceef530f38e5166f21ed17d", "parents": [ "a49ed0bf427a8328a3296eebedc7697fe5098dbf" ], "author": { "name": "Hiroshi Shimamoto", "email": "h-shimamoto@ct.jp.nec.com", "time": "Mon Nov 30 14:59:44 2009 +0900" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 02 10:24:37 2009 +0100" }, "message": "locking, task_struct: Reduce size on TRACE_IRQFLAGS and 64bit\n\nReorder task_struct field for TRACE_IRQFLAGS to remove padding\non 64-bit.\n\nSigned-off-by: Hiroshi Shimamoto \u003ch-shimamoto@ct.jp.nec.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c4B135F50.8070302@ct.jp.nec.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "6b62fe019e39edfd1dbe3f224ecd0a87d9365223", "tree": "024a4935a646688874b579aa01e9b85f18c41c46", "parents": [ "3a9089fd78367e2c6c815129030b790a0f5c2715" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Wed Dec 02 07:23:10 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Dec 02 09:59:02 2009 +0100" }, "message": "tracing/syscalls: Make syscall events print callbacks static\n\nenter_syscall_print_##sname and exit_syscall_print_##sname don\u0027t\nneed to have a global scope.

This means that some data won\u0027t make it into the\ncache this time. To support this, a new FS-Cache function is added\nfscache_maybe_release_page() that replaces what the netfs releasepage()\nfunctions used to do with respect to the cache.\n\nThe decisions fscache_maybe_release_page() makes are counted and displayed\nthrough /proc/fs/fscache/stats on a line labelled \"VmScan\". There are four\ncounters provided: \"nos\u003dN\" - pages that weren\u0027t pending storage; \"gon\u003dN\" -\npages that were pending storage when we first looked, but weren\u0027t by the time\nwe got the object lock; \"bsy\u003dN\" - pages that we ignored as they were actively\nbeing written when we looked; and \"can\u003dN\" - pages that we cancelled the storage\nof.\n\nWhat I\u0027d really like to do is alter the behaviour of the cancellation\nheuristics, depending on how necessary it is to expel pages. If there are\nplenty of other pages that aren\u0027t waiting to be written to the cache that\ncould be ejected first, then it would be nice to hold up on immediate\ncancellation of cache writes - but I don\u0027t see a way of doing that.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "1bccf513ac49d44604ba1cddcc29f5886e70f1b6", "tree": "096ba75a3d02018c5f6e1857aaf1d41471733850", "parents": [ "6897e3df8fc37bd4a58bbcdef8306da7fc175584" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:25 2009 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:25 2009 +0000" }, "message": "FS-Cache: Fix lock misorder in fscache_write_op()\n\nFS-Cache has two structs internally for keeping track of the internal state of\na cached file: the fscache_cookie struct, which represents the netfs\u0027s state,\nand fscache_object struct, which represents the cache\u0027s state. Each has a\npointer that points to the other (when both are in existence), and each has a\nspinlock for pointer maintenance.\n\nSince netfs operations approach these structures from the cookie side, they get\nthe cookie lock first, then the object lock. Cache operations, on the other\nhand, approach from the object side, and get the object lock first. It is not\nthen permitted for a cache operation to get the cookie lock whilst it is\nholding the object lock lest deadlock occur; instead, it must do one of two\nthings:\n\n (1) increment the cookie usage counter, drop the object lock and then get both\n locks in order, or\n\n (2) simply hold the object lock as certain parts of the cookie may not be\n altered whilst the object lock is held.\n\nIt is also not permitted to follow either pointer without holding the lock at\nthe end you start with. To break the pointers between the cookie and the\nobject, both locks must be held.\n\nfscache_write_op(), however, violates the locking rules: It attempts to get the\ncookie lock without (a) checking that the cookie pointer is a valid pointer,\nand (b) holding the object lock to protect the cookie pointer whilst it follows\nit. This is so that it can access the pending page store tree without\ninterference from __fscache_write_page().\n\nThis is fixed by splitting the cookie lock, such that the page store tracking\ntree is protected by its own lock, and checking that the cookie pointer is\nnon-NULL before we attempt to follow it whilst holding the object lock.\n\nThe new lock is subordinate to both the cookie lock and the object lock, and so\nshould be taken after those.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "4fbf4291aa15926cd4fdca0ffe9122e89d0459db", "tree": "ec2195c39ef8117acea598af4a5c20c77f67aa0b", "parents": [ "440f0affe247e9990c8f8778f1861da4fd7d5e50" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:04 2009 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:11:04 2009 +0000" }, "message": "FS-Cache: Allow the current state of all objects to be dumped\n\nAllow the current state of all fscache objects to be dumped by doing:\n\n\tcat /proc/fs/fscache/objects\n\nBy default, all objects and all fields will be shown.

If another work item is queued, but the\nitem\u0027s event hasn\u0027t occurred, then the work item should requeue itself and\nyield the thread back to the slow-work facility by returning.\n\nThis can be used by CacheFiles for an object that is being created on one\nthread to wait for an object being deleted on another thread where there is\nnothing on the queue for the creation to go and wait behind. As soon as an\nitem appears on the queue that could be given thread time instead, CacheFiles\ncan stick the creating object back on the queue and return to the slow-work\nfacility - assuming the object deletion didn\u0027t also complete.\n\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\n" }, { "commit": "31ba99d304494cb28fa8671ccc769c5543e1165d", "tree": "ea2d839fb70798cf6a3b55ccc87f749e14e14f1d", "parents": [ "8fba10a42d191de612e60e7009c8f0313f90a9b3" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:10:53 2009 +0000" }, "committer": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Nov 19 18:10:53 2009 +0000" }, "message": "SLOW_WORK: Allow the owner of a work item to determine if it is queued or not\n\nAdd a function (slow_work_is_queued()) to permit the owner of a work item to\ndetermine if the item is queued or not.\n\nThe work item is counted as being queued if it is actually on the queue, not\njust if it is pending.

hw-breakpoints layer on top of perf events\n\nThis patch rebase the implementation of the breakpoints API on top of\nperf events instances.\n\nEach breakpoints are now perf events that handle the\nregister scheduling, thread/cpu attachment, etc..\n\nThe new layering is now made as follows:\n\n ptrace kgdb ftrace perf syscall\n \\ | / /\n \\ | / /\n /\n Core breakpoint API /\n /\n | /\n | /\n\n Breakpoints perf events\n\n |\n |\n\n Breakpoints PMU ---- Debug Register constraints handling\n (Part of core breakpoint API)\n |\n |\n\n Hardware debug registers\n\nReasons of this rewrite:\n\n- Use the centralized/optimized pmu registers scheduling,\n implying an easier arch integration\n- More powerful register handling: perf attributes (pinned/flexible\n events, exclusive/non-exclusive, tunable period, etc...)\n\nImpact:\n\n- New perf ABI: the hardware breakpoints counters\n- Ptrace breakpoints setting remains tricky and still needs some per\n thread breakpoints references.\n\nTodo (in the order):\n\n- Support breakpoints perf counter events for perf tools (ie: implement\n perf_bpcounter_event())\n- Support from perf tools\n\nChanges in v2:\n\n- Follow the perf \"event \" rename\n- The ptrace regression have been fixed (ptrace breakpoint perf events\n weren\u0027t released when a task ended)\n- Drop the struct hw_breakpoint and store generic fields in\n perf_event_attr.\n- Separate core and arch specific headers, drop\n asm-generic/hw_breakpoint.h and create linux/hw_breakpoint.h\n- Use new generic len/type for breakpoint\n- Handle off case: when breakpoints api is not supported by an arch\n\nChanges in v3:\n\n- Fix broken CONFIG_KVM, we need to propagate the breakpoint api\n changes to kvm when we exit the guest and restore the bp registers\n to the host.\n\nChanges in v4:\n\n- Drop the hw_breakpoint_restore() stub as it is only used by KVM\n- EXPORT_SYMBOL_GPL hw_breakpoint_restore() as KVM can be built as a\n module\n- Restore the breakpoints unconditionally on kvm guest exit:\n TIF_DEBUG_THREAD doesn\u0027t anymore cover every cases of running\n breakpoints and vcpu-\u003earch.switch_db_regs might not always be\n set when the guest used debug registers.\n (Waiting for a reliable optimization)\n\nChanges in v5:\n\n- Split-up the asm-generic/hw-breakpoint.h moving to\n linux/hw_breakpoint.h into a separate patch\n- Optimize the breakpoints restoring while switching from kvm guest\n to host. We only want to restore the state if we have active\n breakpoints to the host, otherwise we don\u0027t care about messed-up\n address registers.\n- Add asm/hw_breakpoint.h to Kbuild\n- Fix bad breakpoint type in trace_selftest.c\n\nChanges in v6:\n\n- Fix wrong header inclusion in trace.h (triggered a build\n error with CONFIG_FTRACE_SELFTEST\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Prasad \u003cprasad@linux.vnet.ibm.com\u003e\nCc: Alan Stern \u003cstern@rowland.harvard.edu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Jan Kiszka \u003cjan.kiszka@web.de\u003e\nCc: Jiri Slaby \u003cjirislaby@gmail.com\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Avi Kivity \u003cavi@redhat.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\n" }, { "commit": "444a2a3bcd6d5bed5c823136f68fcc93c0fe283f", "tree": "6a57308586b4e723238646074e79298845803520", "parents": [ "09879b99d44d701c603935ef2549004405d7f8f9" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Fri Nov 06 04:13:05 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Nov 08 10:31:42 2009 +0100" }, "message": "tracing, perf_events: Protect the buffer from recursion in perf\n\nWhile tracing using events with perf, if one enables the\nlockdep:lock_acquire event, it will infect every other perf\ntrace events.\n\nBasically, you can enable whatever set of trace events through\nperf but if this event is part of the set, the only result we\ncan get is a long list of lock_acquire events of rcu read lock,\nand only that.\n\nThis is because of a recursion inside perf.\n\n1) When a trace event is triggered, it will fill a per cpu\n buffer and submit it to perf.\n\n2) Perf will commit this event but will also protect some data\n using rcu_read_lock\n\n3) A recursion appears: rcu_read_lock triggers a lock_acquire\n event that will fill the per cpu event and then submit the\n buffer to perf.\n\n4) Perf detects a recursion and ignores it\n\n5) Perf continues its work on the previous event, but its buffer\n has been overwritten by the lock_acquire event, it has then\n been turned into a lock_acquire event of rcu read lock\n\nSuch scenario also happens with lock_release with\nrcu_read_unlock().\n\nWe could turn the rcu_read_lock() into __rcu_read_lock() to drop\nthe lock debugging from perf fast path, but that would make us\nlose the rcu debugging and that doesn\u0027t prevent from other\npossible kind of recursion from perf in the future.\n\nThis patch adds a recursion protection based on a counter on the\nperf trace per cpu buffers to solve the problem.\n\n-v2: Fixed lost whitespace, added reviewed-by tag\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nReviewed-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Jason Baron \u003cjbaron@redhat.com\u003e\nLKML-Reference: \u003c1257477185-7838-1-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" } ], "next": "afa08974fe80c198b8650f73ed8ab59135ca10d0" }
