IRQ_PER_CPU is set\n\nIn __do_IRQ(), the normal case is that IRQ_DISABLED is checked and if set\nthe handler (handle_IRQ_event()) is not called.\n\nEarlier in __do_IRQ(), if IRQ_PER_CPU is set the code does not check\nIRQ_DISABLED and calls the handler even though IRQ_DISABLED is set. This\nbehavior seems unintentional.\n\nOne user encountering this behavior is the CPE handler (in\narch/ia64/kernel/mca.c). When the CPE handler encounters too many CPEs\n(such as a solid single bit error), it sets up a polling timer and disables\nthe CPE interrupt (to avoid excessive overhead logging the stream of single\nbit errors). disable_irq_nosync() is called which sets IRQ_DISABLED. The\nIRQ_PER_CPU flag was previously set (in ia64_mca_late_init()). The net\nresult is the CPE handler gets called even though it is marked disabled.\n\nIf the behavior of not checking IRQ_DISABLED when IRQ_PER_CPU is set is\nintentional, it would be worthy of a comment describing the intended\nbehavior. disable_irq_nosync() does call chip-\u003edisable() to provide a\nchipset specifiec interface for disabling the interrupt, which avoids this\nissue when used.\n\nSigned-off-by: Russ Anderson \u003crja@sgi.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "cb0c78cc94a63871cad051674516b38e4a8aef95", "tree": "2f90ad36bcfebf29caa3bc38cc5775e53ac58a54", "parents": [ "231f7e9d029a710c14352bff3b8d3753cb9bfde8" ], "author": { "name": "Jeff Dike", "email": "jdike@addtoit.com", "time": "Wed May 09 02:33:22 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed May 09 12:30:48 2007 -0700" }, "message": "Fix Linuxdoc comment\n\nA linuxdoc comment had fallen out of date - it refers to an argument which no\nlonger exists.\n\nSigned-off-by: Jeff Dike \u003cjdike@linux.intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d85a60d85ea5b7c597508c1510c88e657773d378", "tree": "2b5d1a5311074de8c12811e7ddf26e3cda4a41a0", "parents": [ "951744fea0aea9adbd7c8cacb3605f2d69a66f96" ], "author": { "name": "Bernhard Walle", "email": "bwalle@suse.de", "time": "Tue May 08 00:35:24 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Tue May 08 11:15:22 2007 -0700" }, "message": "Add IRQF_IRQPOLL flag (common code)\n\nirqpoll is broken on some architectures that don\u0027t use the IRQ 0 for the timer\ninterrupt like IA64.

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.

genirq: rename desc-\u003ehandler to desc-\u003echip\n\nThis patch-queue improves the generic IRQ layer to be truly generic, by adding\nvarious abstractions and features to it, without impacting existing\nfunctionality.\n\nWhile the queue can be best described as \"fix and improve everything in the\ngeneric IRQ layer that we could think of\", and thus it consists of many\nsmaller features and lots of cleanups, the one feature that stands out most is\nthe new \u0027irq chip\u0027 abstraction.\n\nThe irq-chip abstraction is about describing and coding and IRQ controller\ndriver by mapping its raw hardware capabilities [and quirks, if needed] in a\nstraightforward way, without having to think about \"IRQ flow\"\n(level/edge/etc.) type of details.\n\nThis stands in contrast with the current \u0027irq-type\u0027 model of genirq\narchitectures, which \u0027mixes\u0027 raw hardware capabilities with \u0027flow\u0027 details.\nThe patchset supports both types of irq controller designs at once, and\nconverts i386 and x86_64 to the new irq-chip design.\n\nAs a bonus side-effect of the irq-chip approach, chained interrupt controllers\n(master/slave PIC constructs, etc.) are now supported by design as well.\n\nThe end result of this patchset intends to be simpler architecture-level code\nand more consolidation between architectures.\n\nWe reused many bits of code and many concepts from Russell King\u0027s ARM IRQ\nlayer, the merging of which was one of the motivations for this patchset.\n\nThis patch:\n\nrename desc-\u003ehandler to desc-\u003echip.\n\nOriginally i did not want to do this, because it\u0027s a big patch. 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.
