It provides a way to stop and resume execution of all tasks in\na cgroup by writing in the cgroup filesystem.\n\nThe freezer subsystem in the container filesystem defines a file named\nfreezer.state. Writing \"FROZEN\" to the state file will freeze all tasks\nin the cgroup. Subsequently writing \"RUNNING\" will unfreeze the tasks in\nthe cgroup. Reading will return the current state.\n\n* Examples of usage :\n\n # mkdir /containers/freezer\n # mount -t cgroup -ofreezer freezer /containers\n # mkdir /containers/0\n # echo $some_pid \u003e /containers/0/tasks\n\nto get status of the freezer subsystem :\n\n # cat /containers/0/freezer.state\n RUNNING\n\nto freeze all tasks in the container :\n\n # echo FROZEN \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n FREEZING\n # cat /containers/0/freezer.state\n FROZEN\n\nto unfreeze all tasks in the container :\n\n # echo RUNNING \u003e /containers/0/freezer.state\n # cat /containers/0/freezer.state\n RUNNING\n\nThis is the basic mechanism which should do the right thing for user space\ntask in a simple scenario.\n\nIt\u0027s important to note that freezing can be incomplete. In that case we\nreturn EBUSY. This means that some tasks in the cgroup are busy doing\nsomething that prevents us from completely freezing the cgroup at this\ntime. After EBUSY, the cgroup will remain partially frozen -- reflected\nby freezer.state reporting \"FREEZING\" when read. The state will remain\n\"FREEZING\" until one of these things happens:\n\n\t1) Userspace cancels the freezing operation by writing \"RUNNING\" to\n\t\tthe freezer.state file\n\t2) Userspace retries the freezing operation by writing \"FROZEN\" to\n\t\tthe freezer.state file (writing \"FREEZING\" is not legal\n\t\tand returns EIO)\n\t3) The tasks that blocked the cgroup from entering the \"FROZEN\"\n\t\tstate disappear from the cgroup\u0027s set of tasks.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: export thaw_process]\nSigned-off-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nSigned-off-by: Matt Helsley \u003cmatthltc@us.ibm.com\u003e\nAcked-by: Serge E.

Inspired from the Linux Kernel\nMarkers. Allows complete typing verification by declaring both tracing\nstatement inline functions and probe registration/unregistration static\ninline functions within the same macro \"DEFINE_TRACE\". No format string\nis required. See the tracepoint Documentation and Samples patches for\nusage examples.\n\nTaken from the documentation patch :\n\n\"A tracepoint placed in code provides a hook to call a function (probe)\nthat you can provide at runtime. A tracepoint can be \"on\" (a probe is\nconnected to it) or \"off\" (no probe is attached). When a tracepoint is\n\"off\" it has no effect, except for adding a tiny time penalty (checking\na condition for a branch) and space penalty (adding a few bytes for the\nfunction call at the end of the instrumented function and adds a data\nstructure in a separate section). When a tracepoint is \"on\", the\nfunction you provide is called each time the tracepoint is executed, in\nthe execution context of the caller. When the function provided ends its\nexecution, it returns to the caller (continuing from the tracepoint\nsite).\n\nYou can put tracepoints at important locations in the code. They are\nlightweight hooks that can pass an arbitrary number of parameters, which\nprototypes are described in a tracepoint declaration placed in a header\nfile.\"\n\nAddition and removal of tracepoints is synchronized by RCU using the\nscheduler (and preempt_disable) as guarantees to find a quiescent state\n(this is really RCU \"classic\"). The update side uses rcu_barrier_sched()\nwith call_rcu_sched() and the read/execute side uses\n\"preempt_disable()/preempt_enable()\".\n\nWe make sure the previous array containing probes, which has been\nscheduled for deletion by the rcu callback, is indeed freed before we\nproceed to the next update. It therefore limits the rate of modification\nof a single tracepoint to one update per RCU period. The objective here\nis to permit fast batch add/removal of probes on _different_\ntracepoints.\n\nChangelog :\n- Use #name \":\" #proto as string to identify the tracepoint in the\n tracepoint table. This will make sure not type mismatch happens due to\n connexion of a probe with the wrong type to a tracepoint declared with\n the same name in a different header.\n- Add tracepoint_entry_free_old.\n- Change __TO_TRACE to get rid of the \u0027i\u0027 iterator.\n\nMasami Hiramatsu \u003cmhiramat@redhat.com\u003e :\nTested on x86-64.\n\nPerformance impact of a tracepoint : same as markers, except that it\nadds about 70 bytes of instructions in an unlikely branch of each\ninstrumented function (the for loop, the stack setup and the function\ncall). It currently adds a memory read, a test and a conditional branch\nat the instrumentation site (in the hot path). Immediate values will\neventually change this into a load immediate, test and branch, which\nremoves the memory read which will make the i-cache impact smaller\n(changing the memory read for a load immediate removes 3-4 bytes per\nsite on x86_32 (depending on mov prefixes), or 7-8 bytes on x86_64, it\nalso saves the d-cache hit).\n\nAbout the performance impact of tracepoints (which is comparable to\nmarkers), even without immediate values optimizations, tests done by\nHideo Aoki on ia64 show no regression. His test case was using hackbench\non a kernel where scheduler instrumentation (about 5 events in code\nscheduler code) was added.\n\nQuoting Hideo Aoki about Markers :\n\nI evaluated overhead of kernel marker using linux-2.6-sched-fixes git\ntree, which includes several markers for LTTng, using an ia64 server.\n\nWhile the immediate trace mark feature isn\u0027t implemented on ia64, there\nis no major performance regression. So, I think that we don\u0027t have any\nissues to propose merging marker point patches into Linus\u0027s tree from\nthe viewpoint of performance impact.\n\nI prepared two kernels to evaluate. The first one was compiled without\nCONFIG_MARKERS. The second one was enabled CONFIG_MARKERS.\n\nI downloaded the original hackbench from the following URL:\nhttp://devresources.linux-foundation.org/craiger/hackbench/src/hackbench.c\n\nI ran hackbench 5 times in each condition and calculated the average and\ndifference between the kernels.\n\n The parameter of hackbench: every 50 from 50 to 800\n The number of CPUs of the server: 2, 4, and 8\n\nBelow is the results. As you can see, major performance regression\nwasn\u0027t found in any case. Even if number of processes increases,\ndifferences between marker-enabled kernel and marker- disabled kernel\ndoesn\u0027t increase. Moreover, if number of CPUs increases, the differences\ndoesn\u0027t increase either.\n\nCuriously, marker-enabled kernel is better than marker-disabled kernel\nin more than half cases, although I guess it comes from the difference\nof memory access pattern.\n\n* 2 CPUs\n\nNumber of | without | with | diff | diff |\nprocesses | Marker [Sec] | Marker [Sec] | [Sec] | [%]

When the input is an unsigned long, there is no portable\nway to do this on 64-bit platforms there is no portable way to do this\nsince it requires a 128-bit intermediate result (which gcc does support on\n64-bit platforms but may generate libgcc calls, e.g. on 64-bit s390), but\nsince the output is a 32-bit integer in the cases affected, just simplify\nthe multiply-divide (*3/10 instead of *300/1000).\n\nThe reciprocal multiply used can have off-by-one errors in the upper half\nof the valid output range. This could be avoided at the expense of having\nto deal with a potential 65-bit intermediate result. Since the intent is\nto avoid overflow problems and most of the other time conversions are only\nsemiexact, the off-by-one errors were considered an acceptable tradeoff.\n\nAt Ralf Baechle\u0027s suggestion, this version uses a Perl script to compute\nthe necessary constants. We already have dependencies on Perl for kernel\ncompiles. This does, however, require the Perl module Math::BigInt, which\nis included in the standard Perl distribution starting with version 5.8.0.\nIn order to support older versions of Perl, include a table of canned\nconstants in the script itself, and structure the script so that\nMath::BigInt isn\u0027t required if pulling values from said table.\n\nRunning the script requires that the HZ value is available from the\nMakefile. Thus, this patch also adds the Kconfig variable CONFIG_HZ to the\narchitectures which didn\u0027t already have it (alpha, cris, frv, h8300, m32r,\nm68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or\nsh64 architectures, since Paul Mundt has dealt with those separately in the\nsh tree.\n\nSigned-off-by: H.

It provides infrastructure for more than one parameter,\nand exposes a user mode interface for processes to register pm_qos\nexpectations of processes.\n\nThis interface provides a kernel and user mode interface for registering\nperformance expectations by drivers, subsystems and user space applications on\none of the parameters.\n\nCurrently we have {cpu_dma_latency, network_latency, network_throughput} as\nthe initial set of pm_qos parameters.\n\nThe infrastructure exposes multiple misc device nodes one per implemented\nparameter. The set of parameters implement is defined by pm_qos_power_init()\nand pm_qos_params.h. This is done because having the available parameters\nbeing runtime configurable or changeable from a driver was seen as too easy to\nabuse.\n\nFor each parameter a list of performance requirements is maintained along with\nan aggregated target value. The aggregated target value is updated with\nchanges to the requirement list or elements of the list. Typically the\naggregated target value is simply the max or min of the requirement values\nheld in the parameter list elements.\n\n\u003eFrom kernel mode the use of this interface is simple:\n\npm_qos_add_requirement(param_id, name, target_value):\n\n Will insert a named element in the list for that identified PM_QOS\n parameter with the target value. Upon change to this list the new target is\n recomputed and any registered notifiers are called only if the target value\n is now different.\n\npm_qos_update_requirement(param_id, name, new_target_value):\n\n Will search the list identified by the param_id for the named list element\n and then update its target value, calling the notification tree if the\n aggregated target is changed. with that name is already registered.\n\npm_qos_remove_requirement(param_id, name):\n\n Will search the identified list for the named element and remove it, after\n removal it will update the aggregate target and call the notification tree\n if the target was changed as a result of removing the named requirement.\n\n\u003eFrom user mode:\n\n Only processes can register a pm_qos requirement. To provide for\n automatic cleanup for process the interface requires the process to register\n its parameter requirements in the following way:\n\n To register the default pm_qos target for the specific parameter, the\n process must open one of /dev/[cpu_dma_latency, network_latency,\n network_throughput]\n\n As long as the device node is held open that process has a registered\n requirement on the parameter. The name of the requirement is\n \"process_\u003cPID\u003e\" derived from the current-\u003epid from within the open system\n call.\n\n To change the requested target value the process needs to write a s32\n value to the open device node. This translates to a\n pm_qos_update_requirement call.\n\n To remove the user mode request for a target value simply close the device\n node.\n\n[akpm@linux-foundation.org: fix warnings]\n[akpm@linux-foundation.org: fix build]\n[akpm@linux-foundation.org: fix build again]\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: mark gross \u003cmgross@linux.intel.com\u003e\nCc: \"John W.

The\ncode that today makes this tradeoff just does a rather simple algorithm;\nhowever this is not good enough: There are devices and use cases where a\nlower latency is required than that the higher power saving states provide.\n An example would be audio playback, but another example is the ipw2100\nwireless driver that right now has a very direct and ugly acpi hook to\ndisable some higher power states randomly when it gets certain types of\nerror.\n\nThe proposed solution is to have an interface where drivers can\n\n* announce the maximum latency (in microseconds) that they can deal with\n* modify this latency\n* give up their constraint\n\nand a function where the code that decides on power saving strategy can\nquery the current global desired maximum.\n\nThis patch has a user of each side: on the consumer side, ACPI is patched\nto use this, on the producer side the ipw2100 driver is patched.\n\nA generic maximum latency is also registered of 2 timer ticks (more and you\nlose accurate time tracking after all).\n\nWhile the existing users of the patch are x86 specific, the infrastructure\nis not.

It \"observes\" and maps all locking rules as\nthey occur dynamically (as triggered by the kernel\u0027s natural use of spinlocks,\nrwlocks, mutexes and rwsems). Whenever the lock validator subsystem detects a\nnew locking scenario, it validates this new rule against the existing set of\nrules. If this new rule is consistent with the existing set of rules then the\nnew rule is added transparently and the kernel continues as normal. If the\nnew rule could create a deadlock scenario then this condition is printed out.\n\nWhen determining validity of locking, all possible \"deadlock scenarios\" are\nconsidered: assuming arbitrary number of CPUs, arbitrary irq context and task\ncontext constellations, running arbitrary combinations of all the existing\nlocking scenarios. In a typical system this means millions of separate\nscenarios. This is why we call it a \"locking correctness\" validator - for all\nrules that are observed the lock validator proves it with mathematical\ncertainty that a deadlock could not occur (assuming that the lock validator\nimplementation itself is correct and its internal data structures are not\ncorrupted by some other kernel subsystem). [see more details and conditionals\nof this statement in include/linux/lockdep.h and\nDocumentation/lockdep-design.txt]\n\nFurthermore, this \"all possible scenarios\" property of the validator also\nenables the finding of complex, highly unlikely multi-CPU multi-context races\nvia single single-context rules, increasing the likelyhood of finding bugs\ndrastically. In practical terms: the lock validator already found a bug in\nthe upstream kernel that could only occur on systems with 3 or more CPUs, and\nwhich needed 3 very unlikely code sequences to occur at once on the 3 CPUs.\nThat bug was found and reported on a single-CPU system (!). So in essence a\nrace will be found \"piecemail-wise\", triggering all the necessary components\nfor the race, without having to reproduce the race scenario itself! In its\nshort existence the lock validator found and reported many bugs before they\nactually caused a real deadlock.\n\nTo further increase the efficiency of the validator, the mapping is not per\n\"lock instance\", but per \"lock-class\". For example, all struct inode objects\nin the kernel have inode-\u003einotify_mutex. If there are 10,000 inodes cached,\nthen there are 10,000 lock objects. But -\u003einotify_mutex is a single \"lock\ntype\", and all locking activities that occur against -\u003einotify_mutex are\n\"unified\" into this single lock-class. The advantage of the lock-class\napproach is that all historical -\u003einotify_mutex uses are mapped into a single\n(and as narrow as possible) set of locking rules - regardless of how many\ndifferent tasks or inode structures it took to build this set of rules. The\nset of rules persist during the lifetime of the kernel.\n\nTo see the rough magnitude of checking that the lock validator does, here\u0027s a\nportion of /proc/lockdep_stats, fresh after bootup:\n\n lock-classes: 694 [max: 2048]\n direct dependencies: 1598 [max: 8192]\n indirect dependencies: 17896\n all direct dependencies: 16206\n dependency chains: 1910 [max: 8192]\n in-hardirq chains: 17\n in-softirq chains: 105\n in-process chains: 1065\n stack-trace entries: 38761 [max: 131072]\n combined max dependencies: 2033928\n hardirq-safe locks: 24\n hardirq-unsafe locks: 176\n softirq-safe locks: 53\n softirq-unsafe locks: 137\n irq-safe locks: 59\n irq-unsafe locks: 176\n\nThe lock validator has observed 1598 actual single-thread locking patterns,\nand has validated all possible 2033928 distinct locking scenarios.\n\nMore details about the design of the lock validator can be found in\nDocumentation/lockdep-design.txt, which can also found at:\n\n

(previously we had one SMP debugging\nvariant per architecture, plus a separate generic one for UP builds)\n\nAlso, i\u0027ve enhanced the rwlock debugging facility, it will now track\nwrite-owners. There is new spinlock-owner/CPU-tracking on SMP builds too.\nAll locks have lockup detection now, which will work for both soft and hard\nspin/rwlock lockups.\n\nThe arch-level include files now only contain the minimally necessary\nsubset of the spinlock code - all the rest that can be generalized now\nlives in the generic headers:\n\n include/asm-i386/spinlock_types.h | 16\n include/asm-x86_64/spinlock_types.h | 16\n\nI have also split up the various spinlock variants into separate files,\nmaking it easier to see which does what.
