This feature would be\nuseful if someone wants to group tasks only for accounting purpose and doesnt\nreally want to exercise any control over their cpu consumption.\n\nThe patch below reintroduces the feature. It is based on Paul Menage\u0027s\noriginal patch (Commit 62d0df64065e7c135d0002f069444fbdfc64768f), with\nthese differences:\n\n - Removed load average information. I felt it needs more thought (esp\n\t to deal with SMP and virtualized platforms) and can be added for\n\t 2.6.25 after more discussions.\n - Convert group cpu usage to be nanosecond accurate (as rest of the cfs\n\t stats are) and invoke cpuacct_charge() from the respective scheduler\n\t classes\n\t- Make accounting scalable on SMP systems by splitting the usage\n\t counter to be per-cpu\n\t- Move the code from kernel/cpu_acct.c to kernel/sched.c (since the\n\t code is not big enough to warrant a new file and also this rightly\n\t needs to live inside the scheduler.

These all need the basic abstraction of being\nable to group together multiple processes in an aggregate, in order to\ntrack/limit the resources permitted to those processes, or control\nother behaviour of the processes, and all implement this grouping in\ndifferent ways.\n\nThis patchset provides a framework for tracking and grouping processes\ninto arbitrary \"cgroups\" and assigning arbitrary state to those\ngroupings, in order to control the behaviour of the cgroup as an\naggregate.\n\nThe intention is that the various resource management and\nvirtualization/cgroup efforts can also become task cgroup\nclients, with the result that:\n\n- the userspace APIs are (somewhat) normalised\n\n- it\u0027s easier to test e.g. the ResGroups CPU controller in\n conjunction with the BeanCounters memory controller, or use either of\nthem as the resource-control portion of a virtual server system.\n\n- the additional kernel footprint of any of the competing resource\n management systems is substantially reduced, since it doesn\u0027t need\n to provide process grouping/containment, hence improving their\n chances of getting into the kernel\n\nThis patch:\n\nAdd the main task cgroups framework - the cgroup filesystem, and the\nbasic structures for tracking membership and associating subsystem state\nobjects to tasks.\n\nSigned-off-by: Paul Menage \u003cmenage@google.com\u003e\nCc: Serge E.

It can be used instead of pipe(2) in all cases where those\nwould simply be used to signal events. Their kernel overhead is much lower\nthan pipes, and they do not consume two fds. 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 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.

It attempts to address a variety of concerns\nwith the existing implementation.\n\nA. Management of object queues\n\n A particular concern was the complex management of the numerous object\n queues in SLAB. SLUB has no such queues. Instead we dedicate a slab for\n each allocating CPU and use objects from a slab directly instead of\n queueing them up.\n\nB. Storage overhead of object queues\n\n SLAB Object queues exist per node, per CPU. The alien cache queue even\n has a queue array that contain a queue for each processor on each\n node. For very large systems the number of queues and the number of\n objects that may be caught in those queues grows exponentially. On our\n systems with 1k nodes / processors we have several gigabytes just tied up\n for storing references to objects for those queues This does not include\n the objects that could be on those queues. One fears that the whole\n memory of the machine could one day be consumed by those queues.\n\nC. SLAB meta data overhead\n\n SLAB has overhead at the beginning of each slab. This means that data\n cannot be naturally aligned at the beginning of a slab block. SLUB keeps\n all meta data in the corresponding page_struct. Objects can be naturally\n aligned in the slab. F.e. a 128 byte object will be aligned at 128 byte\n boundaries and can fit tightly into a 4k page with no bytes left over.\n SLAB cannot do this.\n\nD. SLAB has a complex cache reaper\n\n SLUB does not need a cache reaper for UP systems. On SMP systems\n the per CPU slab may be pushed back into partial list but that\n operation is simple and does not require an iteration over a list\n of objects. SLAB expires per CPU, shared and alien object queues\n during cache reaping which may cause strange hold offs.\n\nE. SLAB has complex NUMA policy layer support\n\n SLUB pushes NUMA policy handling into the page allocator. This means that\n allocation is coarser (SLUB does interleave on a page level) but that\n situation was also present before 2.6.13. SLABs application of\n policies to individual slab objects allocated in SLAB is\n certainly a performance concern due to the frequent references to\n memory policies which may lead a sequence of objects to come from\n one node after another. SLUB will get a slab full of objects\n from one node and then will switch to the next.\n\nF. Reduction of the size of partial slab lists\n\n SLAB has per node partial lists. This means that over time a large\n number of partial slabs may accumulate on those lists. These can\n only be reused if allocator occur on specific nodes. SLUB has a global\n pool of partial slabs and will consume slabs from that pool to\n decrease fragmentation.\n\nG. Tunables\n\n SLAB has sophisticated tuning abilities for each slab cache. One can\n manipulate the queue sizes in detail. However, filling the queues still\n requires the uses of the spin lock to check out slabs. SLUB has a global\n parameter (min_slab_order) for tuning. Increasing the minimum slab\n order can decrease the locking overhead. The bigger the slab order the\n less motions of pages between per CPU and partial lists occur and the\n better SLUB will be scaling.\n\nG. Slab merging\n\n We often have slab caches with similar parameters. SLUB detects those\n on boot up and merges them into the corresponding general caches. This\n leads to more effective memory use. About 50% of all caches can\n be eliminated through slab merging. This will also decrease\n slab fragmentation because partial allocated slabs can be filled\n up again. Slab merging can be switched off by specifying\n slub_nomerge on boot up.\n\n Note that merging can expose heretofore unknown bugs in the kernel\n because corrupted objects may now be placed differently and corrupt\n differing neighboring objects. Enable sanity checks to find those.\n\nH. Diagnostics\n\n The current slab diagnostics are difficult to use and require a\n recompilation of the kernel. SLUB contains debugging code that\n is always available (but is kept out of the hot code paths).\n SLUB diagnostics can be enabled via the \"slab_debug\" option.\n Parameters can be specified to select a single or a group of\n slab caches for diagnostics. This means that the system is running\n with the usual performance and it is much more likely that\n race conditions can be reproduced.\n\nI. Resiliency\n\n If basic sanity checks are on then SLUB is capable of detecting\n common error conditions and recover as best as possible to allow the\n system to continue.\n\nJ. Tracing\n\n Tracing can be enabled via the slab_debug\u003dT,\u003cslabcache\u003e option\n during boot. SLUB will then protocol all actions on that slabcache\n and dump the object contents on free.\n\nK. On demand DMA cache creation.\n\n Generally DMA caches are not needed. If a kmalloc is used with\n __GFP_DMA then just create this single slabcache that is needed.\n For systems that have no ZONE_DMA requirement the support is\n completely eliminated.\n\nL. Performance increase\n\n Some benchmarks have shown speed improvements on kernbench in the\n range of 5-10%. The locking overhead of slub is based on the\n underlying base allocation size. If we can reliably allocate\n larger order pages then it is possible to increase slub\n performance much further. The anti-fragmentation patches may\n enable further performance increases.\n\nTested on:\ni386 UP + SMP, x86_64 UP + SMP + NUMA emulation, IA64 NUMA + Simulator\n\nSLUB Boot options\n\nslub_nomerge\t\tDisable merging of slabs\nslub_min_order\u003dx\tRequire a minimum order for slab caches.
