There is no\nprotection against entries being added to or removed from a chain while the\nchain is in use. The issues were discussed in this thread:\n\n http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113018709002036\u0026w\u003d2\n\nWe noticed that notifier chains in the kernel fall into two basic usage\nclasses:\n\n\t\"Blocking\" chains are always called from a process context\n\tand the callout routines are allowed to sleep;\n\n\t\"Atomic\" chains can be called from an atomic context and\n\tthe callout routines are not allowed to sleep.\n\nWe decided to codify this distinction and make it part of the API. Therefore\nthis set of patches introduces three new, parallel APIs: one for blocking\nnotifiers, one for atomic notifiers, and one for \"raw\" notifiers (which is\nreally just the old API under a new name). New kinds of data structures are\nused for the heads of the chains, and new routines are defined for\nregistration, unregistration, and calling a chain. The three APIs are\nexplained in include/linux/notifier.h and their implementation is in\nkernel/sys.c.\n\nWith atomic and blocking chains, the implementation guarantees that the chain\nlinks will not be corrupted and that chain callers will not get messed up by\nentries being added or removed. For raw chains the implementation provides no\nguarantees at all; users of this API must provide their own protections. (The\nidea was that situations may come up where the assumptions of the atomic and\nblocking APIs are not appropriate, so it should be possible for users to\nhandle these things in their own way.)\n\nThere are some limitations, which should not be too hard to live with. For\natomic/blocking chains, registration and unregistration must always be done in\na process context since the chain is protected by a mutex/rwsem. Also, a\ncallout routine for a non-raw chain must not try to register or unregister\nentries on its own chain. (This did happen in a couple of places and the code\nhad to be changed to avoid it.)\n\nSince atomic chains may be called from within an NMI handler, they cannot use\nspinlocks for synchronization. Instead we use RCU. The overhead falls almost\nentirely in the unregister routine, which is okay since unregistration is much\nless frequent that calling a chain.\n\nHere is the list of chains that we adjusted and their classifications. None\nof them use the raw API, so for the moment it is only a placeholder.\n\n ATOMIC CHAINS\n -------------\narch/i386/kernel/traps.c:\t\ti386die_chain\narch/ia64/kernel/traps.c:\t\tia64die_chain\narch/powerpc/kernel/traps.c:\t\tpowerpc_die_chain\narch/sparc64/kernel/traps.c:\t\tsparc64die_chain\narch/x86_64/kernel/traps.c:\t\tdie_chain\ndrivers/char/ipmi/ipmi_si_intf.c:\txaction_notifier_list\nkernel/panic.c:\t\t\t\tpanic_notifier_list\nkernel/profile.c:\t\t\ttask_free_notifier\nnet/bluetooth/hci_core.c:\t\thci_notifier\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_chain\nnet/ipv4/netfilter/ip_conntrack_core.c:\tip_conntrack_expect_chain\nnet/ipv6/addrconf.c:\t\t\tinet6addr_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_chain\nnet/netfilter/nf_conntrack_core.c:\tnf_conntrack_expect_chain\nnet/netlink/af_netlink.c:\t\tnetlink_chain\n\n BLOCKING CHAINS\n ---------------\narch/powerpc/platforms/pseries/reconfig.c:\tpSeries_reconfig_chain\narch/s390/kernel/process.c:\t\tidle_chain\narch/x86_64/kernel/process.c\t\tidle_notifier\ndrivers/base/memory.c:\t\t\tmemory_chain\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_policy_notifier_list\ndrivers/cpufreq/cpufreq.c\t\tcpufreq_transition_notifier_list\ndrivers/macintosh/adb.c:\t\tadb_client_list\ndrivers/macintosh/via-pmu.c\t\tsleep_notifier_list\ndrivers/macintosh/via-pmu68k.c\t\tsleep_notifier_list\ndrivers/macintosh/windfarm_core.c\twf_client_list\ndrivers/usb/core/notify.c\t\tusb_notifier_list\ndrivers/video/fbmem.c\t\t\tfb_notifier_list\nkernel/cpu.c\t\t\t\tcpu_chain\nkernel/module.c\t\t\t\tmodule_notify_list\nkernel/profile.c\t\t\tmunmap_notifier\nkernel/profile.c\t\t\ttask_exit_notifier\nkernel/sys.c\t\t\t\treboot_notifier_list\nnet/core/dev.c\t\t\t\tnetdev_chain\nnet/decnet/dn_dev.c:\t\t\tdnaddr_chain\nnet/ipv4/devinet.c:\t\t\tinetaddr_chain\n\nIt\u0027s possible that some of these classifications are wrong.

The current code\nwill not attempt recovery if the MCA surfaces in kernel\ncontext (privilage mode 0). This patch adds a check for cases\nwhere the user initiated the load that surfaces in kernel\ninterrupt code.\n\nAn example is a user process lauching a load from memory\nand the data in memory had bad ECC. Before the bad data\ngets to the CPU register, and interrupt comes in. The\ncode jumps to the IVT interrupt entry point and begins\nexecution in kernel context. The process of saving the\nuser registers (SAVE_REST) causes the bad data to be loaded\ninto a CPU register, triggering the MCA. The MCA surfaces in\nkernel context, even though the load was initiated from\nuser context.\n\nAs suggested by David and Tony, this patch uses an exception\ntable like approach, puting the tagged recovery addresses in\na searchable table. One difference from the exception table\nis that MCAs do not surface in precise places (such as with\na TLB miss), so instead of tagging specific instructions,\naddress ranges are registers.

it.\n\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "9d78f43d1fd3e028bfd37510ce847d0896f71f78", "tree": "0eab1902fecc563d500a3147344d6940e46171c4", "parents": [

sysfs.\n\nItems (attributes) are similar to /proc/cpuinfo.\n\n1) /sys/devices/system/cpu/cpuX/topology/physical_package_id:\n\trepresent the physical package id of cpu X;\n2) /sys/devices/system/cpu/cpuX/topology/core_id:\n\trepresent the cpu core id to cpu X;\n3) /sys/devices/system/cpu/cpuX/topology/thread_siblings:\n\trepresent the thread siblings to cpu X in the same core;\n4) /sys/devices/system/cpu/cpuX/topology/core_siblings:\n\trepresent the thread siblings to cpu X in the same physical package;\n\nTo implement it in an architecture-neutral way, a new source file,\ndriver/base/topology.c, is to export the 5 attributes.\n\nIf one architecture wants to support this feature, it just needs to\nimplement 4 defines, typically in file include/asm-XXX/topology.h.\nThe 4 defines are:\n#define topology_physical_package_id(cpu)\n#define topology_core_id(cpu)\n#define topology_thread_siblings(cpu)\n#define topology_core_siblings(cpu)\n\nThe type of **_id is int.\nThe type of siblings is cpumask_t.\n\nTo be consistent on all architectures, the 4 attributes should have\ndeafult values if their values are unavailable. Below is the rule.\n\n1) physical_package_id: If cpu has no physical package id, -1 is the\ndefault value.\n\n2) core_id: If cpu doesn\u0027t support multi-core, its core id is 0.\n\n3) thread_siblings: Just include itself, if the cpu doesn\u0027t support\nHT/multi-thread.\n\n4) core_siblings: Just include itself, if the cpu doesn\u0027t support\nmulti-core and HT/Multi-thread.\n\nSo be careful when declaring the 4 defines in include/asm-XXX/topology.h.\n\nIf an attribute isn\u0027t defined on an architecture, it won\u0027t be exported.\n\nThank Nathan, Greg, Andi, Paul and Venki.\n\nThe patch provides defines for i386/x86_64/ia64.\n\nSigned-off-by: Zhang, Yanmin \u003cyanmin.zhang@intel.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a58786917ce23c2a26c3e099c3cdba32a35eeceb", "tree": "4740de51febbe16934d24d94cb80432a7547cb26", "parents": [ "af14aca90e0cdfccd71f9947c45b6ea2cf321dcb" ], "author": { "name": "Bjorn Helgaas", "email": "bjorn.helgaas@hp.com", "time": "Mon Jan 30 16:32:31 2006 -0700" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu Feb 02 13:25:54 2006 -0800" }, "message": "[IA64] avoid broken SAL_CACHE_FLUSH implementations\n\nIf SAL_CACHE_FLUSH drops interrupts, complain about it and fall back to\nusing PAL_CACHE_FLUSH instead.\n\nThis is to work around a defect in HP rx5670 firmware: when an interrupt\noccurs during SAL_CACHE_FLUSH, SAL drops the interrupt but leaves it marked\n\"in-service\", which leaves the interrupt (and others of equal or lower\npriority) masked.\n\nSigned-off-by: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n" }, { "commit": "59ed2f59e4ea6a32f9591e378da7935f713a7000", "tree": "a1276a611dbb1bc44685ef8af363e99603e60047", "parents": [ "9ad11ab48b1ad618bf47076e9e579f267f5306c2", "b8e4d89357fc434618a59c1047cac72641191805" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Feb 01 22:06:15 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Wed Feb 01 22:06:15 2006 -0800" }, "message": "Merge branch \u0027release\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6\n" }, { "commit": "b0a06623dc4caf6dfb6a84419507643471676d20", "tree": "4808417fe23fcb3e352c0ce347abb6218fc2263e", "parents": [ "3ee68c4af3fd7228c1be63254b9f884614f9ebb2" ], "author": { "name": "Keith Owens", "email": "kaos@sgi.com", "time": "Sun Jan 22 10:55:25 2006 +1100" }, "committer": { "name": "Tony Luck", "email": "tony.luck@intel.com", "time": "Thu Jan 26 13:23:27 2006 -0800" }, "message": "[IA64] Delete MCA/INIT sigdelayed code\n\nThe only user of the MCA/INIT sigdelayed code (SGI\u0027s I/O probing) has\nmoved from the kernel into SAL.

To solve this:\n\n- I\u0027ve added a \u0027domain distance\u0027 function, which is used to cache\n measurement results. Each distance is only measured once. This means\n that e.g. on NUMA distances of 0, 1 and 2 might be measured, on HT\n distances 0 and 1, and on SMP distance 0 is measured. The code walks\n the domain tree to determine the distance, so it automatically follows\n whatever hierarchy an architecture sets up. This cuts down on the boot\n time significantly and removes the O(N^2) limit. The only assumption\n is that migration costs can be expressed as a function of domain\n distance - this covers the overwhelming majority of existing systems,\n and is a good guess even for more assymetric systems.\n\n [ People hacking systems that have assymetries that break this\n assumption (e.g. different CPU speeds) should experiment a bit with\n the cpu_distance() function. Adding a -\u003emigration_distance factor to\n the domain structure would be one possible solution - but lets first\n see the problem systems, if they exist at all. Lets not overdesign. ]\n\nAnother problem was that only a single cache-size was used for measuring\nthe cost of migration, and most architectures didnt set that variable\nup. Furthermore, a single cache-size does not fit NUMA hierarchies with\nL3 caches and does not fit HT setups, where different CPUs will often\nhave different \u0027effective cache sizes\u0027. To solve this problem:\n\n- Instead of relying on a single cache-size provided by the platform and\n sticking to it, the code now auto-detects the \u0027effective migration\n cost\u0027 between two measured CPUs, via iterating through a wide range of\n cachesizes. The code searches for the maximum migration cost, which\n occurs when the working set of the test-workload falls just below the\n \u0027effective cache size\u0027. I.e. real-life optimized search is done for\n the maximum migration cost, between two real CPUs.\n\n This, amongst other things, has the positive effect hat if e.g. two\n CPUs share a L2/L3 cache, a different (and accurate) migration cost\n will be found than between two CPUs on the same system that dont share\n any caches.\n\n(The reliable measurement of migration costs is tricky - see the source\nfor details.)\n\nFurthermore i\u0027ve added various boot-time options to override/tune\nmigration behavior.\n\nFirstly, there\u0027s a blanket override for autodetection:\n\n\tmigration_cost\u003d1000,2000,3000\n\nwill override the depth 0/1/2 values with 1msec/2msec/3msec values.\n\nSecondly, there\u0027s a global factor that can be used to increase (or\ndecrease) the autodetected values:\n\n\tmigration_factor\u003d120\n\nwill increase the autodetected values by 20%. This option is useful to\ntune things in a workload-dependent way - e.g. if a workload is\ncache-insensitive then CPU utilization can be maximized by specifying\nmigration_factor\u003d0.\n\nI\u0027ve tested the autodetection code quite extensively on x86, on 3\nP3/Xeon/2MB, and the autodetected values look pretty good:\n\nDual Celeron (128K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 131072, cpu: 467 MHz):\n ---------------------\n [00] [01]\n [00]: - 1.7(1)\n [01]: 1.7(1) -\n ---------------------\n cacheflush times [2]: 0.0 (0) 1.7 (1784008)\n ---------------------\n\nHere the slow memory subsystem dominates system performance, and even\nthough caches are small, the migration cost is 1.7 msecs.\n\nDual HT P4 (512K L2 cache):\n\n ---------------------\n migration cost matrix (max_cache_size: 524288, cpu: 2379 MHz):\n ---------------------\n [00] [01] [02] [03]\n [00]: - 0.4(1) 0.0(0) 0.4(1)\n [01]: 0.4(1) - 0.4(1) 0.0(0)\n [02]: 0.0(0) 0.4(1) - 0.4(1)\n [03]: 0.4(1) 0.0(0) 0.4(1) -\n ---------------------\n cacheflush times [2]: 0.0 (33900) 0.4 (448514)\n ---------------------\n\nHere it can be seen that there is no migration cost between two HT\nsiblings (CPU#0/2 and CPU#1/3 are separate physical CPUs).

This avoids \"attribute aliasing\", which can cause a\nmachine check.\n\nSample problem scenario:\n - Machine supports VGA, so it has uncacheable (UC) MMIO at 640K-768K\n - efi_memmap_init() discards any write-back (WB) memory in the first granule\n - Application (e.g., \"hwinfo\") mmaps /dev/mem, offset 0\n - hwinfo receives UC mapping (the default, since memmap says \"no WB here\")\n - Machine check abort (on chipsets that don\u0027t support UC access to WB\n memory, e.g., sx1000)\n\nIn the scenario above, the only choices are\n - Use WB for hwinfo mmap. Can\u0027t do this because it causes attribute\n aliasing with the UC mapping for the VGA MMIO space.\n - Use UC for hwinfo mmap. Can\u0027t do this because the chipset may not\n support UC for that region.\n - Disallow the hwinfo mmap with -EINVAL.
