(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.

This waiter wakes up and after a few instructions it\nattempts to acquire the cv internal lock, but that lock is still held by\nthe thread calling pthread_cond_signal. 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.

Fixing that is hard, while SYSEMU is easier to implement.\n\n* This version of the patch includes some suggestions of Jeff Dike to avoid\n adding any instructions to the syscall fast path, plus some other little\n changes, by myself, to make it work even when the syscall is executed with\n SYSENTER (but I\u0027m unsure about them). It has been widely tested for quite a\n lot of time.\n\n* Various fixed were included to handle the various switches between\n various states, i.e. when for instance a syscall entry is traced with one of\n PT_SYSCALL / _SYSEMU / _SINGLESTEP and another one is used on exit.\n Basically, this is done by remembering which one of them was used even after\n the call to ptrace_notify().\n\n* We\u0027re combining TIF_SYSCALL_EMU with TIF_SYSCALL_TRACE or TIF_SINGLESTEP\n to make do_syscall_trace() notice that the current syscall was started with\n SYSEMU on entry, so that no notification ought to be done in the exit path;\n this is a bit of a hack, so this problem is solved in another way in next\n patches.\n\n* Also, the effects of the patch:\n\"Ptrace - i386: fix Syscall Audit interaction with singlestep\"\nare cancelled; they are restored back in the last patch of this series.\n\nDetailed descriptions of the patches doing this kind of processing follow (but\nI\u0027ve already summed everything up).\n\n* Fix behaviour when changing interception kind #1.\n\n In do_syscall_trace(), we check the status of the TIF_SYSCALL_EMU flag\n only after doing the debugger notification; but the debugger might have\n changed the status of this flag because he continued execution with\n PTRACE_SYSCALL, so this is wrong. This patch fixes it by saving the flag\n status before calling ptrace_notify().\n\n* Fix behaviour when changing interception kind #2:\n avoid intercepting syscall on return when using SYSCALL again.\n\n A guest process switching from using PTRACE_SYSEMU to PTRACE_SYSCALL\n crashes.\n\n The problem is in arch/i386/kernel/entry.S. The current SYSEMU patch\n inhibits the syscall-handler to be called, but does not prevent\n do_syscall_trace() to be called after this for syscall completion\n interception.\n\n The appended patch fixes this. It reuses the flag TIF_SYSCALL_EMU to\n remember \"we come from PTRACE_SYSEMU and now are in PTRACE_SYSCALL\", since\n the flag is unused in the depicted situation.\n\n* Fix behaviour when changing interception kind #3:\n avoid intercepting syscall on return when using SINGLESTEP.\n\n When testing 2.6.9 and the skas3.v6 patch, with my latest patch and had\n problems with singlestepping on UML in SKAS with SYSEMU. It looped\n receiving SIGTRAPs without moving forward. EIP of the traced process was\n the same for all SIGTRAPs.\n\nWhat\u0027s missing is to handle switching from PTRACE_SYSCALL_EMU to\nPTRACE_SINGLESTEP in a way very similar to what is done for the change from\nPTRACE_SYSCALL_EMU to PTRACE_SYSCALL_TRACE.\n\nI.e., after calling ptrace(PTRACE_SYSEMU), on the return path, the debugger is\nnotified and then wake ups the process; the syscall is executed (or skipped,\nwhen do_syscall_trace() returns 0, i.e. when using PTRACE_SYSEMU), and\ndo_syscall_trace() is called again. Since we are on the return path of a\nSYSEMU\u0027d syscall, if the wake up is performed through ptrace(PTRACE_SYSCALL),\nwe must still avoid notifying the parent of the syscall exit. Now, this\nbehaviour is extended even to resuming with PTRACE_SINGLESTEP.\n\nSigned-off-by: Paolo \u0027Blaisorblade\u0027 Giarrusso \u003cblaisorblade@yahoo.it\u003e\nCc: Jeff Dike \u003cjdike@addtoit.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "c3c433e4f33afe255389ba3b1a003dc8deb3de9a", "tree": "071304e15e21e0a93c17050000a682f4ae1a98c1", "parents": [ "57c4ce3cbfba1bb0da7f37b9328a713cbd5d0919" ], "author": { "name": "Shaohua Li", "email": "shaohua.li@intel.com", "time": "Sat Sep 03 15:57:07 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:06:18 2005 -0700" }, "message": "[PATCH] add suspend/resume for timer\n\nThe timers lack .suspend/.resume methods.

On P4, with a PAE kernel, this saves 180\ncycles per ptep_get_and_clear, for a whopping 92160 cycles savings for a\nfull address space destruction.\n\npte_clear_full is not yet used, but is provided for future optimizations\n(in particular, when running inside of a hypervisor that queues page table\nupdates, the full hint allows us to avoid queueing unnecessary page table\nupdate for an address space in the process of being destroyed.\n\nThis is not a huge win, but it does help a bit, and sets the stage for\nfurther hypervisor optimization of the mm layer on all architectures.\n\nSigned-off-by: Zachary Amsden \u003czach@vmware.com\u003e\nCc: Christoph Lameter \u003cchristoph@lameter.com\u003e\nCc: \u003clinux-mm@kvack.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fa5b08d5f818063d18433194f20359ef2ae50254", "tree": "f2b2bc88347a618f0c4b535d57d2a5271a5eb98e", "parents": [ "0e5c9f39f64d8a55c5db37a5ea43e37d3422fd92" ], "author": { "name": "Kyle Moffett", "email": "mrmacman_g4@mac.com", "time": "Sat Sep 03 15:55:03 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:05:48 2005 -0700" }, "message": "[PATCH] sab: consolidate kmem_bufctl_t\n\nThis is used only in slab.c and each architecture gets to define whcih\nunderlying type is to be used.\n\nSeems a bit silly - move it to slab.c and use the same type for all\narchitectures: unsigned int.\n\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0e5c9f39f64d8a55c5db37a5ea43e37d3422fd92", "tree": "2b7da9a3813f1ce475d276d55243b2675b90349b", "parents": [ "02b0ccef903e85673ead74ddb7c431f2f7ce183d" ], "author": { "name": "Chen, Kenneth W", "email": "kenneth.w.chen@intel.com", "time": "Sat Sep 03 15:55:02 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@evo.osdl.org", "time": "Mon Sep 05 00:05:46 2005 -0700" }, "message": "[PATCH] remove hugetlb_clean_stale_pgtable() and fix huge_pte_alloc()\n\nI don\u0027t think we need to call hugetlb_clean_stale_pgtable() anymore\nin 2.6.13 because of the rework with free_pgtables().

There are three forms of the advice:\n\n1) Burst as much as possible, it is not necessary to end bursts\n on some particular boundary for best performance.\n\n2) Burst on some byte count multiple. A DMA burst to some multiple of\n number of bytes may be done, but it is important to end the burst\n on an exact multiple for best performance.\n\n The best example of this I am aware of are the PPC64 PCI\n controllers, where if you end a burst mid-cacheline then\n chip has to refetch the data and the IOMMU translations\n which hurts performance a lot.\n\n3) Burst on a single byte count multiple. Bursts shall end\n exactly on the next multiple boundary for best performance.\n\n Sparc64 and Alpha\u0027s PCI controllers operate this way. They\n disconnect any device which tries to burst across a cacheline\n boundary.\n\n Actually, newer sparc64 PCI controllers do not have this behavior.\n That is why the \"pdev\" is passed into the interface, so I can\n add code later to check which PCI controller the system is using\n and give advice accordingly.\n\nSigned-off-by: David S.

This enables you to establish a handler to be run when a\nfunction returns.\n\n1. API\n\nTwo new functions are added to kprobes:\n\n\tint register_kretprobe(struct kretprobe *rp);\n\tvoid unregister_kretprobe(struct kretprobe *rp);\n\n2. Registration and unregistration\n\n2.1 Register\n\n To register a function-return probe, the user populates the following\n fields in a kretprobe object and calls register_kretprobe() with the\n kretprobe address as an argument:\n\n kp.addr - the function\u0027s address\n\n handler - this function is run after the ret instruction executes, but\n before control returns to the return address in the caller.\n\n maxactive - The maximum number of instances of the probed function that\n can be active concurrently. For example, if the function is non-\n recursive and is called with a spinlock or mutex held, maxactive \u003d 1\n should be enough. If the function is non-recursive and can never\n relinquish the CPU (e.g., via a semaphore or preemption), NR_CPUS should\n be enough. maxactive is used to determine how many kretprobe_instance\n objects to allocate for this particular probed function. If maxactive \u003c\u003d\n 0, it is set to a default value (if CONFIG_PREEMPT maxactive\u003dmax(10, 2 *\n NR_CPUS) else maxactive\u003dNR_CPUS)\n\n For example:\n\n struct kretprobe rp;\n rp.kp.addr \u003d /* entrypoint address */\n rp.handler \u003d /*return probe handler */\n rp.maxactive \u003d /* e.g., 1 or NR_CPUS or 0, see the above explanation */\n register_kretprobe(\u0026rp);\n\n The following field may also be of interest:\n\n nmissed - Initialized to zero when the function-return probe is\n registered, and incremented every time the probed function is entered but\n there is no kretprobe_instance object available for establishing the\n function-return probe (i.e., because maxactive was set too low).\n\n2.2 Unregister\n\n To unregiter a function-return probe, the user calls\n unregister_kretprobe() with the same kretprobe object as registered\n previously. If a probed function is running when the return probe is\n unregistered, the function will return as expected, but the handler won\u0027t\n be run.\n\n3. Limitations\n\n3.1 This patch supports only the i386 architecture, but patches for\n x86_64 and ppc64 are anticipated soon.\n\n3.2 Return probes operates by replacing the return address in the stack\n (or in a known register, such as the lr register for ppc). This may\n cause __builtin_return_address(0), when invoked from the return-probed\n function, to return the address of the return-probes trampoline.\n\n3.3 This implementation uses the \"Multiprobes at an address\" feature in\n 2.6.12-rc3-mm3.\n\n3.4 Due to a limitation in multi-probes, you cannot currently establish\n a return probe and a jprobe on the same function.
