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] | [%] |\n--------------------------------------------------------------\n 50 | 4.811 | 4.872 | +0.061 | +1.27 |\n 100 | 9.854 | 10.309 | +0.454 | +4.61 |\n 150 | 15.602 | 15.040 | -0.562 | -3.6 |\n 200 | 20.489 | 20.380 | -0.109 | -0.53 |\n 250 | 25.798 | 25.652 | -0.146 | -0.56 |\n 300 | 31.260 | 30.797 | -0.463 | -1.48 |\n 350 | 36.121 | 35.770 | -0.351 | -0.97 |\n 400 | 42.288 | 42.102 | -0.186 | -0.44 |\n 450 | 47.778 | 47.253 | -0.526 | -1.1 |\n 500 | 51.953 | 52.278 | +0.325 | +0.63 |\n 550 | 58.401 | 57.700 | -0.701 | -1.2 |\n 600 | 63.334 | 63.222 | -0.112 | -0.18 |\n 650 | 68.816 | 68.511 | -0.306 | -0.44 |\n 700 | 74.667 | 74.088 | -0.579 | -0.78 |\n 750 | 78.612 | 79.582 | +0.970 | +1.23 |\n 800 | 85.431 | 85.263 | -0.168 | -0.2 |\n--------------------------------------------------------------\n\n* 4 CPUs\n\nNumber of | without | with | diff | diff |\nprocesses | Marker [Sec] | Marker [Sec] | [Sec] | [%] |\n--------------------------------------------------------------\n 50 | 2.586 | 2.584 | -0.003 | -0.1 |\n 100 | 5.254 | 5.283 | +0.030 | +0.56 |\n 150 | 8.012 | 8.074 | +0.061 | +0.76 |\n 200 | 11.172 | 11.000 | -0.172 | -1.54 |\n 250 | 13.917 | 14.036 | +0.119 | +0.86 |\n 300 | 16.905 | 16.543 | -0.362 | -2.14 |\n 350 | 19.901 | 20.036 | +0.135 | +0.68 |\n 400 | 22.908 | 23.094 | +0.186 | +0.81 |\n 450 | 26.273 | 26.101 | -0.172 | -0.66 |\n 500 | 29.554 | 29.092 | -0.461 | -1.56 |\n 550 | 32.377 | 32.274 | -0.103 | -0.32 |\n 600 | 35.855 | 35.322 | -0.533 | -1.49 |\n 650 | 39.192 | 38.388 | -0.804 | -2.05 |\n 700 | 41.744 | 41.719 | -0.025 | -0.06 |\n 750 | 45.016 | 44.496 | -0.520 | -1.16 |\n 800 | 48.212 | 47.603 | -0.609 | -1.26 |\n--------------------------------------------------------------\n\n* 8 CPUs\n\nNumber of | without | with | diff | diff |\nprocesses | Marker [Sec] | Marker [Sec] | [Sec] | [%] |\n--------------------------------------------------------------\n 50 | 2.094 | 2.072 | -0.022 | -1.07 |\n 100 | 4.162 | 4.273 | +0.111 | +2.66 |\n 150 | 6.485 | 6.540 | +0.055 | +0.84 |\n 200 | 8.556 | 8.478 | -0.078 | -0.91 |\n 250 | 10.458 | 10.258 | -0.200 | -1.91 |\n 300 | 12.425 | 12.750 | +0.325 | +2.62 |\n 350 | 14.807 | 14.839 | +0.032 | +0.22 |\n 400 | 16.801 | 16.959 | +0.158 | +0.94 |\n 450 | 19.478 | 19.009 | -0.470 | -2.41 |\n 500 | 21.296 | 21.504 | +0.208 | +0.98 |\n 550 | 23.842 | 23.979 | +0.137 | +0.57 |\n 600 | 26.309 | 26.111 | -0.198 | -0.75 |\n 650 | 28.705 | 28.446 | -0.259 | -0.9 |\n 700 | 31.233 | 31.394 | +0.161 | +0.52 |\n 750 | 34.064 | 33.720 | -0.344 | -1.01 |\n 800 | 36.320 | 36.114 | -0.206 | -0.57 |\n--------------------------------------------------------------\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@polymtl.ca\u003e\nAcked-by: Masami Hiramatsu \u003cmhiramat@redhat.com\u003e\nAcked-by: \u0027Peter Zijlstra\u0027 \u003cpeterz@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "53167a3ef23df561d898dee636f3393e9fba937c", "tree": "1619560ee2db5dc3d43e1f53dd4188fd849fd98f", "parents": [ "81324364b76eba592255d4b712e522f9fd8d25f4" ], "author": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Fri Oct 03 02:01:51 2008 +0400" }, "committer": { "name": "Alexey Dobriyan", "email": "adobriyan@gmail.com", "time": "Fri Oct 10 04:18:57 2008 +0400" }, "message": "proc: move PROC_PAGE_MONITOR to fs/proc/Kconfig\n\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\n" }, { "commit": "9e94cd325bb8ed8abe13f29b64fb54c1dec633a8", "tree": "7708f15465c092270b455c5569c2cfe24b2b340d", "parents": [ "9c0d2a20fe331946c1a65a5865faf56e93255c5c" ], "author": { "name": "Andi Kleen", "email": "ak@linux.intel.com", "time": "Sat Aug 16 07:53:05 2008 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Aug 16 17:13:43 2008 -0700" }, "message": "Move sysctl check into debugging section and don\u0027t make it default y\n\nI noticed that sysctl_check.o was the largest object file in\na allnoconfig build in kernel/*.\n\n 36243 0 0 36243 8d93 kernel/sysctl_check.o\n\nThis is because it was default y and \u0026\u0026 EMBEDDED.

Major\nand minor are either an integer or * for all. Access is a composition of r\n(read), w (write), and m (mknod).\n\nThe root device cgroup starts with rwm to \u0027all\u0027.

This choice was therefore moved to\ninit/Kconfig, which worked, but placed the choice between classic and\npreemptible RCU at the top level, a very obtuse choice indeed.\n\nThis patch changes from the Kconfig \"choice\" mechanism to a pair of booleans,\nonly one of which (CONFIG_PREEMPT_RCU) is user-visible, and is located in\nkernel/Kconfig.preempt, where one would expect it to be.

Also things like accessing\n\t rq-\u003elock while reading cpu usage becomes easier if the code lived in\n\t kernel/sched.c)\n\nThe patch also modifies the cpu controller not to provide the same accounting\ninformation.\n\nTested-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\n\n Tested the patches on top of 2.6.24-rc3. The patches work fine. Ran\n some simple tests like cpuspin (spin on the cpu), ran several tasks in\n the same group and timed them. Compared their time stamps with\n cpuacct.usage.\n\nSigned-off-by: Srivatsa Vaddagiri \u003cvatsa@linux.vnet.ibm.com\u003e\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "529a73fbaeee2f3bd932be8b54665994133be6ae", "tree": "89376052e434af5a68a4c8adfbeaf75b2e0f93c6", "parents": [ "e4e9a7adebfc01bfa2a46c76615c249a4082dfec" ], "author": { "name": "Mike Frysinger", "email": "michael.frysinger@analog.com", "time": "Fri Nov 23 14:28:44 2007 +0800" }, "committer": { "name": "Bryan Wu", "email": "bryan.wu@analog.com", "time": "Fri Nov 23 14:28:44 2007 +0800" }, "message": "Blackfin arch: punt CONFIG_BFIN -- we already have CONFIG_BLACKFIN\n\nSigned-off-by: Mike Frysinger \u003cmichael.frysinger@analog.com\u003e\nSigned-off-by: Bryan Wu \u003cbryan.wu@analog.com\u003e\n\n" }, { "commit": "57d5f66b86079efac5c9a7843cce2a9bcbe58fb8", "tree": "720942bfb200f46da6c77535a110106dce80f9eb", "parents": [ "42614fcde7bfdcbe43a7b17035c167dfebc354dd" ], "author": { "name": "Eric W.

When used in the kernel, it can\noffer an fd-bridge to enable, for example, functionalities like KAIO or\nsyslets/threadlets to signal to an fd the completion of certain operations.\nBut more in general, an eventfd can be used by the kernel to signal readiness,\nin a POSIX poll/select way, of interfaces that would otherwise be incompatible\nwith it. The API is:\n\nint eventfd(unsigned int count);\n\nThe eventfd API accepts an initial \"count\" parameter, and returns an eventfd\nfd. It supports poll(2) (POLLIN, POLLOUT, POLLERR), read(2) and write(2).\n\nThe POLLIN flag is raised when the internal counter is greater than zero.\n\nThe POLLOUT flag is raised when at least a value of \"1\" can be written to the\ninternal counter.\n\nThe POLLERR flag is raised when an overflow in the counter value is detected.\n\nThe write(2) operation can never overflow the counter, since it blocks (unless\nO_NONBLOCK is set, in which case -EAGAIN is returned).\n\nBut the eventfd_signal() function can do it, since it\u0027s supposed to not sleep\nduring its operation.\n\nThe read(2) function reads the __u64 counter value, and reset the internal\nvalue to zero. If the value read is equal to (__u64) -1, an overflow happened\non the internal counter (due to 2^64 eventfd_signal() posts that has never\nbeen retired - unlickely, but possible).\n\nThe write(2) call writes an __u64 count value, and adds it to the current\ncounter. The eventfd fd supports O_NONBLOCK also.\n\nOn the kernel side, we have:\n\nstruct file *eventfd_fget(int fd);\nint eventfd_signal(struct file *file, unsigned int n);\n\nThe eventfd_fget() should be called to get a struct file* from an eventfd fd\n(this is an fget() + check of f_op being an eventfd fops pointer).\n\nThe kernel can then call eventfd_signal() every time it wants to post an event\nto userspace.

If you want to reliably fetch signals on\nthe signalfd file, you need to block them with sigprocmask(SIG_BLOCK). This\nseems to be working fine on my Dual Opteron machine. I made a quick test\nprogram for it:\n\nhttp://www.xmailserver.org/signafd-test.c\n\nThe signalfd() system call implements signal delivery into a file descriptor\nreceiver. The signalfd file descriptor if created with the following API:\n\nint signalfd(int ufd, const sigset_t *mask, size_t masksize);\n\nThe \"ufd\" parameter allows to change an existing signalfd sigmask, w/out going\nto close/create cycle (Linus idea). Use \"ufd\" \u003d\u003d -1 if you want a brand new\nsignalfd file.\n\nThe \"mask\" allows to specify the signal mask of signals that we are interested\nin. The \"masksize\" parameter is the size of \"mask\".\n\nThe signalfd fd supports the poll(2) and read(2) system calls. The poll(2)\nwill return POLLIN when signals are available to be dequeued. As a direct\nconsequence of supporting the Linux poll subsystem, the signalfd fd can use\nused together with epoll(2) too.\n\nThe read(2) system call will return a \"struct signalfd_siginfo\" structure in\nthe userspace supplied buffer. The return value is the number of bytes copied\nin the supplied buffer, or -1 in case of error. The read(2) call can also\nreturn 0, in case the sighand structure to which the signalfd was attached,\nhas been orphaned. The O_NONBLOCK flag is also supported, and read(2) will\nreturn -EAGAIN in case no signal is available.\n\nIf the size of the buffer passed to read(2) is lower than sizeof(struct\nsignalfd_siginfo), -EINVAL is returned. A read from the signalfd can also\nreturn -ERESTARTSYS in case a signal hits the process.
