Requesting the shared irq line from another driver result in a\nspurious interrupt storm which finally disables the interrupt line.\n\nI have seen similar behaviour on resume before (the hardware does not\nwork anymore so I can not verify).\n\nChange the spurious disable logic to increment the disable depth and\nmark the interrupt with an extra flag which allows us to reenable the\ninterrupt when a new driver arrives which requests the same irq\nline. In the worst case this will disable the irq again via the\nspurious trap, but there is a decent chance that the new driver is the\none which can handle the already asserted interrupt and makes the box\nusable again.\n\nEric Biederman said further: This case also happens on a regular basis\nin kdump kernels where we deliberately don\u0027t shutdown the hardware\nbefore starting the new kernel.

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

On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. 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. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386. I\u0027ve runtested the\nmain part of the code on FRV and i386, though I can\u0027t test most of the drivers.\nI\u0027ve also done partial conversion for powerpc and MIPS - these at least compile\nwith minimal configurations.\n\nThis will affect all archs. Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely.

First it allocates a\nplatform dependent routing value for an interrupt the ``vector\u0027\u0027 and then it\nfigures out from the vector which irq you are on.\n\nThis msi backwards allocator suffers from two basic problems. The allocator\nsuffers because it is trying to do something that is architecture specific in\na generic way making it brittle, inflexible, and tied to tightly to the\narchitecture implementation. The alloctor also suffers from it\u0027s very\nbackwards nature as it has tied things together that should have no\ndependencies.\n\nTo solve the basic dynamic irq allocation problem two new architecture\nspecific functions are added: create_irq and destroy_irq.\n\ncreate_irq takes no input and returns an unused irq number, that won\u0027t be\nreused until it is returned to the free poll with destroy_irq. The irq then\ncan be used for any purpose although the only initial consumer is the msi\ncode.\n\ndestroy_irq takes an irq number allocated with create_irq and returns it to\nthe free pool.\n\nMaking this functionality per architecture increases the simplicity of the irq\nallocation code and increases it\u0027s flexibility.\n\ndynamic_irq_init() and dynamic_irq_cleanup() are added to automate the\nirq_desc initializtion that should happen for dynamic irqs.\n\nSigned-off-by: Eric W.

My\nprimary focus is on x86_64 but I have touched other architectures where\nnecessary to keep them from breaking.\n\n- To increase the number of irqs I modify the code to look at the (cpu,\n vector) pair instead of just looking at the vector.\n\n With a large number of irqs available systems with a large irq count no\n longer need to compress their irq numbers to fit.

But\nright now they _don\u0027t have_ that refcounting ... which means sharing a\nwakeup-capable IRQ can\u0027t work correctly in some configurations.\n\nThis patch adds the refcount and flag mechanisms to set_irq_wake() -- which\nis what {en,dis}able_irq_wake() call -- and minimal documentation of what\nthe irq wake mechanism does.\n\nDrivers relying on the older (broken) \"toggle\" semantics will trigger a\nwarning; that\u0027ll be a handful of drivers on ARM systems.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "912b2539e1e062cec73e2e61448e507f7719bd08", "tree": "233807569ee5e0ab3118dd54c0ae9164fec8343e", "parents": [ "70b97a7f0b19cf1f2619deb5cc41e8b78c591aa7", "39ab9c212aac48f2744f2fd7722fa639ec048eb7" ], "author": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:28:34 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:28:34 2006 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc:\n powerpc: add defconfig for Freescale MPC8349E-mITX board\n powerpc: Add base support for the Freescale MPC8349E-mITX eval board\n Documentation: correct values in MPC8548E SEC example node\n [POWERPC] Actually copy over i8259.c to arch/ppc/syslib this time\n [POWERPC] Add new interrupt mapping core and change platforms to use it\n [POWERPC] Copy i8259 code back to arch/ppc\n [POWERPC] New device-tree interrupt parsing code\n [POWERPC] Use the genirq framework\n [PATCH] genirq: Allow fasteoi handler to retrigger disabled interrupts\n [POWERPC] Update the SWIM3 (powermac) floppy driver\n [POWERPC] Fix error handling in detecting legacy serial ports\n [POWERPC] Fix booting on Momentum \"Apache\" board (a Maple derivative)\n [POWERPC] Fix various offb and BootX-related issues\n [POWERPC] Add a default config for 32-bit CHRP machines\n [POWERPC] fix implicit declaration on cell.\n [POWERPC] change get_property to return void *\n" }, { "commit": "366c7f554e888e51b8395f9b07b273fe775c7ff3", "tree": "324fab660758f1c5be4585ca2fcdb313feb53cef", "parents": [ "0a9da4bd8eb30fb3f36e841c2cc72e426a17bbe2" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 03 00:25:25 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:27:09 2006 -0700" }, "message": "[PATCH] lockdep: annotate enable_in_hardirq()\n\nMake use of local_irq_enable_in_hardirq() API to annotate places that enable\nhardirqs in hardirq context.\n\nHas no effect on non-lockdep kernels.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "243c7621aac4ed1aa79524c9a1cecf7c05a28124", "tree": "d8f7a1fce57c9349183bfd9ab6738a763078db85", "parents": [ "8b8f319fc7f4ab59f567d6a401a62659b3d37007" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Jul 03 00:25:06 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 03 15:27:06 2006 -0700" }, "message": "[PATCH] lockdep: annotate genirq\n\nTeach special (recursive) locking code to the lock validator.

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.
