That\u0027s why.\n\nCPEI(Corrected Platform Error Interrupt) is ia64 specific irq, is\nallowed to pin to particular processor which selected by the platform, and\neven it is PER_CPU but it has set_affinity handler (\u003diosapic_set_affinity)\nas same as other IO-SAPIC-level interrupts. (I don\u0027t know why, but\nI guess that there would be typical situation where the handler for\nmigration is needed, such as hotplug - the processor going to be\noffline/hot-removed.)\n\nTo shut up this warning, there are 2 way at least:\n a) fix CPEI stuff\n b) prohibit setting affinity to PER_CPU irq\n\nI\u0027m not sure what stuff of CPEI need to be fixed, but I think that\nreturning error to attempting move PER_CPU irq is useful for all\napplications since it will never work.\n\nFollowing small patch takes b) style.\nIt works, the warning disappeared and irqbalance still runs well.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nCc: Arjan van de Ven \u003carjan@infradead.org\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by:

Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller.

It \"observes\" and maps all locking rules as\nthey occur dynamically (as triggered by the kernel\u0027s natural use of spinlocks,\nrwlocks, mutexes and rwsems). Whenever the lock validator subsystem detects a\nnew locking scenario, it validates this new rule against the existing set of\nrules. If this new rule is consistent with the existing set of rules then the\nnew rule is added transparently and the kernel continues as normal. If the\nnew rule could create a deadlock scenario then this condition is printed out.\n\nWhen determining validity of locking, all possible \"deadlock scenarios\" are\nconsidered: assuming arbitrary number of CPUs, arbitrary irq context and task\ncontext constellations, running arbitrary combinations of all the existing\nlocking scenarios. In a typical system this means millions of separate\nscenarios. This is why we call it a \"locking correctness\" validator - for all\nrules that are observed the lock validator proves it with mathematical\ncertainty that a deadlock could not occur (assuming that the lock validator\nimplementation itself is correct and its internal data structures are not\ncorrupted by some other kernel subsystem). [see more details and conditionals\nof this statement in include/linux/lockdep.h and\nDocumentation/lockdep-design.txt]\n\nFurthermore, this \"all possible scenarios\" property of the validator also\nenables the finding of complex, highly unlikely multi-CPU multi-context races\nvia single single-context rules, increasing the likelyhood of finding bugs\ndrastically. In practical terms: the lock validator already found a bug in\nthe upstream kernel that could only occur on systems with 3 or more CPUs, and\nwhich needed 3 very unlikely code sequences to occur at once on the 3 CPUs.\nThat bug was found and reported on a single-CPU system (!). So in essence a\nrace will be found \"piecemail-wise\", triggering all the necessary components\nfor the race, without having to reproduce the race scenario itself! In its\nshort existence the lock validator found and reported many bugs before they\nactually caused a real deadlock.\n\nTo further increase the efficiency of the validator, the mapping is not per\n\"lock instance\", but per \"lock-class\". For example, all struct inode objects\nin the kernel have inode-\u003einotify_mutex. If there are 10,000 inodes cached,\nthen there are 10,000 lock objects. But -\u003einotify_mutex is a single \"lock\ntype\", and all locking activities that occur against -\u003einotify_mutex are\n\"unified\" into this single lock-class. The advantage of the lock-class\napproach is that all historical -\u003einotify_mutex uses are mapped into a single\n(and as narrow as possible) set of locking rules - regardless of how many\ndifferent tasks or inode structures it took to build this set of rules. The\nset of rules persist during the lifetime of the kernel.\n\nTo see the rough magnitude of checking that the lock validator does, here\u0027s a\nportion of /proc/lockdep_stats, fresh after bootup:\n\n lock-classes: 694 [max: 2048]\n direct dependencies: 1598 [max: 8192]\n indirect dependencies: 17896\n all direct dependencies: 16206\n dependency chains: 1910 [max: 8192]\n in-hardirq chains: 17\n in-softirq chains: 105\n in-process chains: 1065\n stack-trace entries: 38761 [max: 131072]\n combined max dependencies: 2033928\n hardirq-safe locks: 24\n hardirq-unsafe locks: 176\n softirq-safe locks: 53\n softirq-unsafe locks: 137\n irq-safe locks: 59\n irq-unsafe locks: 176\n\nThe lock validator has observed 1598 actual single-thread locking patterns,\nand has validated all possible 2033928 distinct locking scenarios.\n\nMore details about the design of the lock validator can be found in\nDocumentation/lockdep-design.txt, which can also found at:\n\n http://redhat.com/~mingo/lockdep-patches/lockdep-design.txt\n\n[bunk@stusta.de: cleanups]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Adrian Bunk \u003cbunk@stusta.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "5a43a066b11ac2fe84cf67307f20b83bea390f83", "tree": "d4770958575f4e7592620d9a0d36c431ecceefc9", "parents": [ "3e9a69275f23baec86b54febc5dad0b2fc7fb200" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Mon Jul 03 19:54:59 2006 +1000" }, "committer": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Mon Jul 03 19:54:59 2006 +1000" }, "message": "[PATCH] genirq: Allow fasteoi handler to retrigger disabled interrupts\n\nMake the fasteoi handler mark disabled interrupts as pending if they\nhappen anyway.

But having\nboth \"desc-\u003ehandler\", \"desc-\u003ehandle_irq\" and \"action-\u003ehandler\" caused a\nlarge degree of confusion and made the code appear alot less clean than it\ntruly is.\n\nI have also attempted a dual approach as well by introducing a\ndesc-\u003echip alias - but that just wasnt robust enough and broke\nfrequently.\n\nSo lets get over with this quickly. The conversion was done automatically\nvia scripts and converts all the code in the kernel.\n\nThis renaming patch is the first one amongst the patches, so that the\nremaining patches can stay flexible and can be merged and split up\nwithout having some big monolithic patch act as a merge barrier.\n\n[akpm@osdl.org: build fix]\n[akpm@osdl.org: another build fix]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "908dcecda1d18803b5823f30e6c47d2882dc0cf1", "tree": "2e40b7484baa65af9aa4460ae958d445725f484f", "parents": [ "a5d6839b75ca4a29b5e0a5595914a8715e8f746d" ], "author": { "name": "Jan Beulich", "email": "jbeulich@novell.com", "time": "Fri Jun 23 02:06:00 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:43:08 2006 -0700" }, "message": "[PATCH] adjust handle_IRR_event() return type\n\nCorrect the return type of handle_IRQ_event() (inconsistency noticed during\nXen development), and remove redundant declarations.
