Looking at the poll function cpu_idle_poll(), and\nthe implementation of trace_cpu_idle_rcuidle(), the problem becomes very clear:\ncpu_idle_poll() lacks calls to rcu_idle_enter/exit(), and trace_cpu_idle_rcuidle()\ncalls them in the reverse order - first rcu_idle_exit(), and then rcu_idle_enter().\nHence the even/odd alternative sequencing of rdtp-\u003edynticks goes for a toss.\n\nAnd powertop readily triggers this because powertop uses the idle-tracing\ninfrastructure extensively.\n\nSo, to fix this, wrap the code in cpu_idle_poll() within rcu_idle_enter/exit(),\nso that it blends properly with the calls inside trace_cpu_idle_rcuidle() and\nthus get the function ordering right.\n\nReported-and-tested-by: Bjørn Mork \u003cbjorn@mork.no\u003e\nCc: Paul McKenney \u003cpaulmck@linux.vnet.ibm.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nSigned-off-by: Srivatsa S.

If only\none function is enabled, then the return code of the write is one,\nand this can confuse the user program in thinking it only wrote 1\nbyte.\n\nLink: http://lkml.kernel.org/r/20130509054413.30398.55650.stgit@mhiramat-M0-7522\n\nCc: Srikar Dronamraju \u003csrikar@linux.vnet.ibm.com\u003e\nCc: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Tom Zanussi \u003ctom.zanussi@intel.com\u003e\nSigned-off-by: Masami Hiramatsu \u003cmasami.hiramatsu.pt@hitachi.com\u003e\n[ Rewrote change log to reflect that this fixes two bugs - SR ]\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "ebb37277796269da36a8bc5d72ed1e8e1fb7d34b", "tree": "0ded627a62a5cec70b18d12825dd858855c135d3", "parents": [ "4de13d7aa8f4d02f4dc99d4609575659f92b3c5a", "f50efd2fdbd9b35b11f5778ed85beb764184bda9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 08 11:51:05 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed May 08 11:51:05 2013 -0700" }, "message": "Merge branch \u0027for-3.10/drivers\u0027 of git://git.kernel.dk/linux-block\n\nPull block driver updates from Jens Axboe:\n \"It might look big in volume, but when categorized, not a lot of\n drivers are touched.

A periodic timer tick at\n HZ\u003d1000 can cause a constant overhead of up to 1.0%. This feature\n removes that overhead - and speeds up the system by 0.5%-1.0% on\n typical distro configs even on modern systems.\n\n - Real-time workload latency reduction: CPUs running critical tasks\n should experience as little jitter as possible. The last remaining\n source of kernel-related jitter was the periodic timer tick.\n\n - A single task executing on a CPU is a pretty common situation,\n especially with an increasing number of cores/CPUs, so this feature\n helps desktop and mobile workloads as well.\n\n The cost of the feature is mainly related to increased timer\n reprogramming overhead when a CPU switches its tick period, and thus\n slightly longer to-idle and from-idle latency.\n\n Configuration-wise a third mode of operation is added to the existing\n two NOHZ kconfig modes:\n\n - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named\n as a config option. This is the traditional Linux periodic tick\n design: there\u0027s a HZ tick going on all the time, regardless of\n whether a CPU is idle or not.\n\n - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ\u003dy], this turns off the\n periodic tick when a CPU enters idle mode.\n\n - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the\n tick when a CPU is idle, also slows the tick down to 1 Hz (one\n timer interrupt per second) when only a single task is running on a\n CPU.\n\n The .config behavior is compatible: existing !CONFIG_NO_HZ and\n CONFIG_NO_HZ\u003dy settings get translated to the new values, without the\n user having to configure anything. CONFIG_NO_HZ_FULL is turned off by\n default.\n\n This feature is based on a lot of infrastructure work that has been\n steadily going upstream in the last 2-3 cycles: related RCU support\n and non-periodic cputime support in particular is upstream already.\n\n This tree adds the final pieces and activates the feature. The pull\n request is marked RFC because:\n\n - it\u0027s marked 64-bit only at the moment - the 32-bit support patch is\n small but did not get ready in time.\n\n - it has a number of fresh commits that came in after the merge\n window. The overwhelming majority of commits are from before the\n merge window, but still some aspects of the tree are fresh and so I\n marked it RFC.\n\n - it\u0027s a pretty wide-reaching feature with lots of effects - and\n while the components have been in testing for some time, the full\n combination is still not very widely used. That it\u0027s default-off\n should reduce its regression abilities and obviously there are no\n known regressions with CONFIG_NO_HZ_FULL\u003dy enabled either.\n\n - the feature is not completely idempotent: there is no 100%\n equivalent replacement for a periodic scheduler/timer tick. In\n particular there\u0027s ongoing work to map out and reduce its effects\n on scheduler load-balancing and statistics. This should not impact\n correctness though, there are no known regressions related to this\n feature at this point.\n\n - it\u0027s a pretty ambitious feature that with time will likely be\n enabled by most Linux distros, and we\u0027d like you to make input on\n its design/implementation, if you dislike some aspect we missed.\n Without flaming us to crisp! :-)\n\n Future plans:\n\n - there\u0027s ongoing work to reduce 1Hz to 0Hz, to essentially shut off\n the periodic tick altogether when there\u0027s a single busy task on a\n CPU. We\u0027d first like 1 Hz to be exposed more widely before we go\n for the 0 Hz target though.\n\n - once we reach 0 Hz we can remove the periodic tick assumption from\n nr_running\u003e\u003d2 as well, by essentially interrupting busy tasks only\n as frequently as the sched_latency constraints require us to do -\n once every 4-40 msecs, depending on nr_running.\n\n I am personally leaning towards biting the bullet and doing this in\n v3.10, like the -rt tree this effort has been going on for too long -\n but the final word is up to you as usual.\n\n More technical details can be found in Documentation/timers/NO_HZ.txt\"\n\n* \u0027timers-nohz-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (39 commits)\n sched: Keep at least 1 tick per second for active dynticks tasks\n rcu: Fix full dynticks\u0027 dependency on wide RCU nocb mode\n nohz: Protect smp_processor_id() in tick_nohz_task_switch()\n nohz_full: Add documentation.\n cputime_nsecs: use math64.h for nsec resolution conversion helpers\n nohz: Select VIRT_CPU_ACCOUNTING_GEN from full dynticks config\n nohz: Reduce overhead under high-freq idling patterns\n nohz: Remove full dynticks\u0027 superfluous dependency on RCU tree\n nohz: Fix unavailable tick_stop tracepoint in dynticks idle\n nohz: Add basic tracing\n nohz: Select wide RCU nocb for full dynticks\n nohz: Disable the tick when irq resume in full dynticks CPU\n nohz: Re-evaluate the tick for the new task after a context switch\n nohz: Prepare to stop the tick on irq exit\n nohz: Implement full dynticks kick\n nohz: Re-evaluate the tick from the scheduler IPI\n sched: New helper to prevent from stopping the tick in full dynticks\n sched: Kick full dynticks CPU that have more than one task enqueued.\n perf: New helper to prevent full dynticks CPUs from stopping tick\n perf: Kick full dynticks CPU if events rotation is needed\n ...\n" }, { "commit": "64049d1973c1735f543eb7a55653e291e108b0cb", "tree": "1b13645ee288a561feccafd9fa84951220f5f651", "parents": [ "f8ce1faf55955de62e0a12e330c6d9a526071f65", "7cc23cd6c0c7d7f4bee057607e7ce01568925717" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun May 05 11:37:16 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun May 05 11:37:16 2013 -0700" }, "message": "Merge branch \u0027perf-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull perf fixes from Ingo Molnar:\n \"Misc fixes plus a small hw-enablement patch for Intel IB model 58\n uncore events\"\n\n* \u0027perf-urgent-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:\n perf/x86/intel/lbr: Demand proper privileges for PERF_SAMPLE_BRANCH_KERNEL\n perf/x86/intel/lbr: Fix LBR filter\n perf/x86: Blacklist all MEM_*_RETIRED events for Ivy Bridge\n perf: Fix vmalloc ring buffer pages handling\n perf/x86/intel: Fix unintended variable name reuse\n perf/x86/intel: Add support for IvyBridge model 58 Uncore\n perf/x86/intel: Fix typo in perf_event_intel_uncore.c\n x86: Eliminate irq_mis_count counted in arch_irq_stat\n" }, { "commit": "f8ce1faf55955de62e0a12e330c6d9a526071f65", "tree": "a3b0ddd3f37e40d3ed0fd2cd433a2723403c8b97", "parents": [ "24d0c2542b38963ae4d5171ecc0a2c1326c656bc", "a53a11f35762ff1d5e268adedf2ab9ce313f871d" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun May 05 10:58:06 2013 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sun May 05 10:58:06 2013 -0700" }, "message": "Merge tag \u0027modules-next-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux\n\nPull mudule updates from Rusty Russell:\n \"We get rid of the general module prefix confusion with a binary config\n option, fix a remove/insert race which Never Happens, and (my\n favorite) handle the case when we have too many modules for a single\n commandline.

Restarting processes on another node after process migration.\n3. Starting duplicated copies of a running process (for reliability\n and high-availablity).\n4. Starting a process from an executable format that is not supported\n by Linux, thus requiring a \"manual execve\" by a user-level utility.\n5. Similarly, starting a process from a networked and/or crypted\n executable that, for confidentiality, licensing or other reasons,\n may not be written to the local file-systems.\n\nThe code that does that was already included in the Linux kernel by the\nCRIU group, in the form of \"prctl(PR_SET_MM)\", but prior to this was\nenclosed within their private \"#ifdef CONFIG_CHECKPOINT_RESTORE\", which is\nnormally disabled. The patch removes those ifdefs.\n\nSigned-off-by: Amnon Shiloh \u003cu3557@miso.sublimeip.com\u003e\nCc: Cyrill Gorcunov \u003cgorcunov@openvz.org\u003e\nCc: Pavel Emelyanov
