      "message": "[PATCH] spinlock consolidation\n\nThis patch (written by me and also containing many suggestions of Arjan van\nde Ven) does a major cleanup of the spinlock code.  It does the following\nthings:\n\n - consolidates and enhances the spinlock/rwlock debugging code\n\n - simplifies the asm/spinlock.h files\n\n - encapsulates the raw spinlock type and moves generic spinlock\n   features (such as -\u003ebreak_lock) into the generic code.\n\n - cleans up the spinlock code hierarchy to get rid of the spaghetti.\n\nMost notably there\u0027s now only a single variant of the debugging code,\nlocated in lib/spinlock_debug.c.  (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. The new layout is:\n\n   SMP                         |  UP\n   ----------------------------|-----------------------------------\n   asm/spinlock_types_smp.h    |  linux/spinlock_types_up.h\n   linux/spinlock_types.h      |  linux/spinlock_types.h\n   asm/spinlock_smp.h          |  linux/spinlock_up.h\n   linux/spinlock_api_smp.h    |  linux/spinlock_api_up.h\n   linux/spinlock.h            |  linux/spinlock.h\n\n/*\n * here\u0027s the role of the various spinlock/rwlock related include files:\n *\n * on SMP builds:\n *\n *  asm/spinlock_types.h: contains the raw_spinlock_t/raw_rwlock_t and the\n *                        initializers\n *\n *  linux/spinlock_types.h:\n *                        defines the generic type and initializers\n *\n *  asm/spinlock.h:       contains the __raw_spin_*()/etc. lowlevel\n *                        implementations, mostly inline assembly code\n *\n *   (also included on UP-debug builds:)\n *\n *  linux/spinlock_api_smp.h:\n *                        contains the prototypes for the _spin_*() APIs.\n *\n *  linux/spinlock.h:     builds the final spin_*() APIs.\n *\n * on UP builds:\n *\n *  linux/spinlock_type_up.h:\n *                        contains the generic, simplified UP spinlock type.\n *                        (which is an empty structure on non-debug builds)\n *\n *  linux/spinlock_types.h:\n *                        defines the generic type and initializers\n *\n *  linux/spinlock_up.h:\n *                        contains the __raw_spin_*()/etc. version of UP\n *                        builds.

I did not try to build\n  non-SMP kernels.  That should be trivial to fix up later if necessary.\n\n  I converted bit ops atomic_hash lock to raw_spinlock_t.  Doing so avoids\n  some ugly nesting of linux/*.h and asm/*.h files.  Those particular locks\n  are well tested and contained entirely inside arch specific code.  I do NOT\n  expect any new issues to arise with them.\n\n If someone does ever need to use debug/metrics with them, then they will\n  need to unravel this hairball between spinlocks, atomic ops, and bit ops\n  that exist only because parisc has exactly one atomic instruction: LDCW\n  (load and clear word).\n\nFrom: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\n\n   ia64 fix\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjanv@infradead.org\u003e\nSigned-off-by: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: Matthew Wilcox \u003cwilly@debian.org\u003e\nSigned-off-by: Hirokazu Takata \u003ctakata@linux-m32r.org\u003e\nSigned-off-by: Mikael Pettersson \u003cmikpe@csd.uu.se\u003e\nSigned-off-by: Benoit Boissinot \u003cbenoit.boissinot@ens-lyon.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

So it goes to sleep and eventually\nthe signalling thread is scheduled in, unlocks the internal lock and wakes\nthe waiter again.\n\nNow, before 2003-09-21 NPTL was using FUTEX_REQUEUE in pthread_cond_signal\nto avoid this performance issue, but it was removed when locks were\nredesigned to the 3 state scheme (unlocked, locked uncontended, locked\ncontended).\n\nFollowing scenario shows why simply using FUTEX_REQUEUE in\npthread_cond_signal together with using lll_mutex_unlock_force in place of\nlll_mutex_unlock is not enough and probably why it has been disabled at\nthat time:\n\nThe number is value in cv-\u003e__data.__lock.\n        thr1            thr2            thr3\n0       pthread_cond_wait\n1       lll_mutex_lock (cv-\u003e__data.__lock)\n0       lll_mutex_unlock (cv-\u003e__data.__lock)\n0       lll_futex_wait (\u0026cv-\u003e__data.__futex, futexval)\n0                       pthread_cond_signal\n1                       lll_mutex_lock (cv-\u003e__data.__lock)\n1                                       pthread_cond_signal\n2                                       lll_mutex_lock (cv-\u003e__data.__lock)\n2                                         lll_futex_wait (\u0026cv-\u003e__data.__lock, 2)\n2                       lll_futex_requeue (\u0026cv-\u003e__data.__futex, 0, 1, \u0026cv-\u003e__data.__lock)\n                          # FUTEX_REQUEUE, not FUTEX_CMP_REQUEUE\n2                       lll_mutex_unlock_force (cv-\u003e__data.__lock)\n0                         cv-\u003e__data.__lock \u003d 0\n0                         lll_futex_wake (\u0026cv-\u003e__data.__lock, 1)\n1       lll_mutex_lock (cv-\u003e__data.__lock)\n0       lll_mutex_unlock (cv-\u003e__data.__lock)\n          # Here, lll_mutex_unlock doesn\u0027t know there are threads waiting\n          # on the internal cv\u0027s lock\n\nNow, I believe it is possible to use FUTEX_REQUEUE in pthread_cond_signal,\nbut it will cost us not one, but 2 extra syscalls and, what\u0027s worse, one of\nthese extra syscalls will be done for every single waiting loop in\npthread_cond_*wait.\n\nWe would need to use lll_mutex_unlock_force in pthread_cond_signal after\nrequeue and lll_mutex_cond_lock in pthread_cond_*wait after lll_futex_wait.\n\nAnother alternative is to do the unlocking pthread_cond_signal needs to do\n(the lock can\u0027t be unlocked before lll_futex_wake, as that is racy) in the\nkernel.\n\nI have implemented both variants, futex-requeue-glibc.patch is the first\none and futex-wake_op{,-glibc}.patch is the unlocking inside of the kernel.\n The kernel interface allows userland to specify how exactly an unlocking\noperation should look like (some atomic arithmetic operation with optional\nconstant argument and comparison of the previous futex value with another\nconstant).\n\nIt has been implemented just for ppc*, x86_64 and i?86, for other\narchitectures I\u0027m including just a stub header which can be used as a\nstarting point by maintainers to write support for their arches and ATM\nwill just return -ENOSYS for FUTEX_WAKE_OP.  The requeue patch has been\n(lightly) tested just on x86_64, the wake_op patch on ppc64 kernel running\n32-bit and 64-bit NPTL and x86_64 kernel running 32-bit and 64-bit NPTL.\n\nWith the following benchmark on UP x86-64 I get:\n\nfor i in nptl-orig nptl-requeue nptl-wake_op; do echo time elf/ld.so --library-path .:$i /tmp/bench; \\\nfor j in 1 2; do echo ( time elf/ld.so --library-path .:$i /tmp/bench ) 2\u003e\u00261; done; done\ntime elf/ld.so --library-path .:nptl-orig /tmp/bench\nreal 0m0.655s user 0m0.253s sys 0m0.403s\nreal 0m0.657s user 0m0.269s sys 0m0.388s\ntime elf/ld.so --library-path .:nptl-requeue /tmp/bench\nreal 0m0.496s user 0m0.225s sys 0m0.271s\nreal 0m0.531s user 0m0.242s sys 0m0.288s\ntime elf/ld.so --library-path .:nptl-wake_op /tmp/bench\nreal 0m0.380s user 0m0.176s sys 0m0.204s\nreal 0m0.382s user 0m0.175s sys 0m0.207s\n\nThe benchmark is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00001.txt\nOlder futex-requeue-glibc.patch version is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00002.txt\nOlder futex-wake_op-glibc.patch version is at:\nhttp://sourceware.org/ml/libc-alpha/2005-03/txt00003.txt\nWill post a new version (just x86-64 fixes so that the patch\napplies against pthread_cond_signal.S) to libc-hacker ml soon.\n\nAttached is the kernel FUTEX_WAKE_OP patch as well as a simple-minded\ntestcase that will not test the atomicity of the operation, but at least\ncheck if the threads that should have been woken up are woken up and\nwhether the arithmetic operation in the kernel gave the expected results.\n\nAcked-by: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Ulrich Drepper \u003cdrepper@redhat.com\u003e\nCc: Jamie Lokier \u003cjamie@shareable.org\u003e\nCc: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Yoichi Yuasa \u003cyuasa@hh.iij4u.or.jp\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Add a system control to set the number of\nretries before a cpu is yielded.\n\nThe reason for the spin lock retry is that the diagnose 0x44 that is used to\ngive up the virtual cpu is quite expensive.  For spin locks that are held only\nfor a short period of time the costs of the diagnoses outweights the savings\nfor spin locks that are held for a longer timer.

Now the trace buffers are subdivided into several\nsubbuffers with pagesize.  Therefore it is now possible to allocate more\nmemory for the trace buffers and more trace records can be written.\n\nIn addition to that, dynamic specification of the size of the trace buffers is\nimplemented.  It is now possible to change the size of a trace buffer using a\nnew debugfs file instance.  When writing a number into this file, the trace\nbuffer size is changed to \u0027number * pagesize\u0027.\n\nIn the past all the traces could be obtained from userspace by accessing files\nin the \"proc\" filesystem.  Now with debugfs we have a new filesystem which\nshould be used for debugging purposes.  This patch moves the debug feature\nfrom procfs to debugfs.\n\nSince the interface of debug_register() changed, all device drivers, which use\nthe debug feature had to be adjusted.\n\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This looks like a left-over after the irq-handling code\nwas consolidated.  The code was moved to kernel/irq/*, but the flags are\nstill left per-arch.\n\nRight now, adding a new IRQ flag to the arch-specific header, like this\npatch does:\nhttp://cvs.sourceforge.net/viewcvs.py/*checkout*/alsa/alsa-driver/utils/patches/pcsp-kernel-2.6.10-03.diff?rev\u003d1.1\nno longer works, it breaks the compilation for all other arches, unless you\nadd that flag to all the other arch-specific headers too.
