Worst of all it seems to vary between SLAB and SLUB.\n\nSo define a common maximum size for kmalloc. For conveniences sake we use\nthe maximum size ever supported which is 32 MB. We limit the maximum size\nto a lower limit if MAX_ORDER does not allow such large allocations.\n\nFor many architectures this patch will have the effect of adding large\nkmalloc sizes. x86_64 adds 5 new kmalloc sizes. So a small amount of\nmemory will be needed for these caches (contemporary SLAB has dynamically\nsizeable node and cpu structure so the waste is less than in the past)\n\nMost architectures will then be able to allocate object with sizes up to\nMAX_ORDER. We have had repeated breakage (in fact whenever we doubled the\nnumber of supported processors) on IA64 because one or the other struct\ngrew beyond what the slab allocators supported. This will avoid future\nissues and f.e. avoid fixes for 2k and 4k cpu support.\n\nCONFIG_LARGE_ALLOCS is no longer necessary so drop it.\n\nIt fixes sparc64 with SLAB.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: \"David S.

This never became actually\nnecessary and the related code always has been subtly broken one way\nor the other. Now that new init model is in place, there is no reason\nto make common helpers capable of handling all corner cases. Exotic\ncases can simply dealt within LLDs as necessary.\n\nThis patch removes port_mask handling in SFF init helpers. SFF init\nhelpers don\u0027t take n_ports argument and interpret it into port_mask\nanymore. All information is carried via port_info. n_ports argument\nis dropped and always two ports are allocated. LLD can tell SFF to\nskip certain port by marking it dummy. Note that SFF code has been\ntreating unuvailable ports this way for a long time until recent\nbreakage fix from Linus and is consistent with how other drivers\nhandle with unavailable ports.\n\nThis fixes 1-port legacy host handling still broken after the recent\nnative mode fix and simplifies SFF init logic. The following changes\nare made...\n\n* ata_pci_init_native_host() and ata_init_legacy_host() both now try\n to initialized whatever they can and mark failed ports dummy. They\n return 0 if any port is successfully initialized.\n\n* ata_pci_prepare_native_host() and ata_pci_init_one() now doesn\u0027t\n take n_ports argument. All info should be specified via port_info\n array. Always two ports are allocated.\n\n* ata_pci_init_bmdma() exported to be used by LLDs in exotic cases.\n\n* port_info handling in all LLDs are standardized - all port_info\n arrays are const stack variable named ppi.

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 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.

We can therefore safely use\nbi_next to link pending requests together, providing we clear it before\nmaking the real call.\n\nSo, we choose to allow each thread to only be active in one\ngeneric_make_request at a time. If a subsequent (recursive) call is made,\nthe bio is linked into a per-thread list, and is handled when the active\ncall completes.\n\nAs the list of pending bios is per-thread, there are no locking issues to\nworry about.\n\nI say above that it is \"safe to delay any call...\". There are, however,\nsome behaviours of a make_request_fn which would make it unsafe. These\ninclude any behaviour that assumes anything will have changed after a\nrecursive call to generic_make_request.\n\nThese could include:\n - waiting for that call to finish and call it\u0027s bi_end_io function.\n md use to sometimes do this (marking the superblock dirty before\n completing a write) but doesn\u0027t any more\n - inspecting the bio for fields that generic_make_request might\n change, such as bi_sector or bi_bdev. It is hard to see a good\n reason for this, and I don\u0027t think anyone actually does it.\n - inspecing the queue to see if, e.g. it is \u0027full\u0027 yet. Again, I\n think this is very unlikely to be useful, or to be done.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nCc: Jens Axboe \u003caxboe@kernel.dk\u003e\nCc: \u003cdm-devel@redhat.com\u003e\n\nAlasdair G Kergon \u003cagk@redhat.com\u003e said:\n\n I can see nothing wrong with this in principle.\n\n For device-mapper at the moment though it\u0027s essential that, while the bio\n mappings may now get delayed, they still get processed in exactly\n the same order as they were passed to generic_make_request().\n\n My main concern is whether the timing changes implicit in this patch\n will make the rare data-corrupting races in the existing snapshot code\n more likely.

This patch avoids that need by moving all free\nobjects onto a lockless_freelist. The regular freelist continues to exist\nand will be used to free objects. So while we consume the\nlockless_freelist the regular freelist may build up objects.\n\nIf we are out of objects on the lockless_freelist then we may check the\nregular freelist. If it has objects then we move those over to the\nlockless_freelist and do this again. There is a significant savings in\nterms of atomic operations that have to be performed.\n\nWe can even free directly to the lockless_freelist if we know that we are\nrunning on the same processor. So this speeds up short lived objects.\nThey may be allocated and freed without taking the slab_lock. This is\nparticular good for netperf.\n\nIn order to maximize the effect of the new faster hotpath we extract the\nhottest performance pieces into inlined functions. These are then inlined\ninto kmem_cache_alloc and kmem_cache_free. So hotpath allocation and\nfreeing no longer requires a subroutine call within SLUB.\n\n[I am not sure that it is worth doing this because it changes the easy to\nread structure of slub just to reduce atomic ops.

Unfortunately for these\ncommands no GPE events for IBF and OBF are triggered. Since nowadays\nthe EC code uses the ec_intr\u003d1 mode by default, this causes these\noperations to timeout, although they don\u0027t fail. In result, all\noperations that you can do with the msi-laptop.c driver take more or\nless 1s to complete, which is awfully slow.\n\nIn one of the more recent kernels (2.6.20?) the EC subsystem has been\nrevamped. With that change the EC timeout has been increased. before\nthat increase the MSI EC accesses were slow -- but not *that* slow,\nhence I took notice of this limitation of the MSI EC hardware only very\nrecently.\n\nThe standard EC operations on the MSI EC as defined in the ACPI spec\nsupport GPE events properly.\n\nThe following patch adds a new argument \"force_poll\" to the\nec_transaction() function (and friends). If set to 1, the function\nwill poll for IBF/OBF even if ec_intr\u003d1 is enabled. If set to 0 the\ncurrent behaviour is used. The msi-laptop driver is modified to make\nuse of this new flag, so that OBF/IBF is polled for the special MSI EC\ntransactions -- but only for them.\n\nSigned-off-by: Lennart Poettering \u003cmzxreary@0pointer.de\u003e\nAcked-by: Alexey Starikovskiy \u003caystarik@gmail.com\u003e\nSigned-off-by: Len Brown \u003clen.brown@intel.com\u003e\n" }, { "commit": "de5603748af8bf7deac403e6ba92887f8d18e812", "tree": "fd93862c70ec0eeba5fe340d7519ab33a9cb1dff", "parents": [ "b5f0adbcc4f16e378882d8f68fe3111df04911be", "225c7b1feef1b41170f7037a5b10a65cd8a42c54" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 19:40:09 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 19:40:09 2007 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of master.kernel.org:/pub/scm/linux/kernel/git/roland/infiniband\n\n* \u0027for-linus\u0027 of master.kernel.org:/pub/scm/linux/kernel/git/roland/infiniband:\n IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adapters\n IB: Put rlimit accounting struct in struct ib_umem\n IB/uverbs: Export ib_umem_get()/ib_umem_release() to modules\n" }, { "commit": "44ce6294d07555c3d313757105fd44b78208407f", "tree": "29659bee16a4d7111124c6f41289bc9c11669e70", "parents": [ "497f050c42e46a4b1f6a9bcd8827fa5d97fe1feb" ], "author": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 18:51:36 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 18:51:36 2007 -0700" }, "message": "Revert \"md: improve partition detection in md array\"\n\nThis reverts commit 5b479c91da90eef605f851508744bfe8269591a0.\n\nQuoth Neil Brown:\n\n \"It causes an oops when auto-detecting raid arrays, and it doesn\u0027t\n seem easy to fix.\n\n The array may not be \u0027open\u0027 when do_md_run is called, so\n bdev-\u003ebd_disk might be NULL, so bd_set_size can oops.\n\n This whole approach of opening an md device before it has been\n assembled just seems to get more and more painful.

This requires SLUB to have\na whole subsystem in order to be compatible with SLAB. Moving node draining\nout of the slab allocators avoids a section of code in SLUB.\n\nMove the node draining so that is is done when the vm statistics are updated.\nAt that point we are already touching all the cachelines with the pagesets of\na processor.\n\nAdd a expire counter there. If we have to update per zone or global vm\nstatistics then assume that the pageset will require subsequent draining.\n\nThe expire counter will be decremented on each vm stats update pass until it\nreaches zero. Then we will drain one batch from the pageset. The draining\nwill cause vm counter updates which will then cause another expiration until\nthe pcp is empty. So we will drain a batch every 3 seconds.\n\nNote that remote node draining is a somewhat esoteric feature that is required\non large NUMA systems because otherwise significant portions of system memory\ncan become trapped in pcp queues. The number of pcp is determined by the\nnumber of processors and nodes in a system. A system with 4 processors and 2\nnodes has 8 pcps which is okay. But a system with 1024 processors and 512\nnodes has 512k pcps with a high potential for large amount of memory being\ncaught in them.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d1187ed21026fd512b87851d0ca26d9ae16f9059", "tree": "35d77758f134f3b69d3e00ca042a5d5ca6a59373", "parents": [ "455c017ae3934797653549704c286e7bcc3a9397" ], "author": { "name": "Christoph Lameter", "email": "clameter@sgi.com", "time": "Wed May 09 02:35:12 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:56 2007 -0700" }, "message": "vmstat: use our own timer events\n\nvmstat is currently using the cache reaper to periodically bring the\nstatistics up to date. The cache reaper does only exists in SLUB as a way to\nprovide compatibility with SLAB. This patch removes the vmstat calls from the\nslab allocators and provides its own handling.\n\nThe advantage is also that we can use a different frequency for the updates.\nRefreshing vm stats is a pretty fast job so we can run this every second and\nstagger this by only one tick. This will lead to some overlap in large\nsystems. F.e a system running at 250 HZ with 1024 processors will have 4 vm\nupdates occurring at once.\n\nHowever, the vm stats update only accesses per node information. It is only\nnecessary to stagger the vm statistics updates per processor in each node. Vm\ncounter updates occurring on distant nodes will not cause cacheline\ncontention.\n\nWe could implement an alternate approach that runs the first processor on each\nnode at the second and then each of the other processor on a node on a\nsubsequent tick. That may be useful to keep a large amount of the second free\nof timer activity. Maybe the timer folks will have some feedback on this one?\n\n[jirislaby@gmail.com: add missing break]\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Jiri Slaby \u003cjirislaby@gmail.com\u003e\nCc: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "8bb7844286fb8c9fce6f65d8288aeb09d03a5e0d", "tree": "f4e305edaedbde05774bb1e4acd89a9475661d2e", "parents": [ "f37bc2712b54ec641e0c0c8634f1a4b61d9956c0" ], "author": { "name": "Rafael J.

Enabling oprofile hurts threaded\n programs because of contention on the mmap_sem cache line.\n\n- Using an atomic_inc()/atomic_dec() on inode ref counter or mm ref counter:\n It\u0027s also a cache line ping pong on SMP. It also increases mmap_sem hold time\n because of cache misses.\n\nMost of these scalability problems come from the fact that futexes are in\none global namespace. As we use a central hash table, we must make sure\nthey are all using the same reference (given by the mm subsystem). We\nchose to force all futexes be \u0027shared\u0027.

Time has come for linux\nto have better threading performance.\n\nThe goal is to permit new futex commands to avoid :\n - Taking the mmap_sem semaphore, conflicting with other subsystems.\n - Modifying a ref_count on mm or an inode, still conflicting with mm or fs.\n\nThis is possible because, for one process using PTHREAD_PROCESS_PRIVATE\nfutexes, we only need to distinguish futexes by their virtual address, no\nmatter the underlying mm storage is.\n\nIf glibc wants to exploit this new infrastructure, it should use new\n_PRIVATE futex subcommands for PTHREAD_PROCESS_PRIVATE futexes.
