The interrupt\nline itself is reenabled after the hard interrupt handler has\nexecuted.\n\nThis requires access to the originating device from hard interrupt\ncontext which is not always possible. There are devices which can only\nbe accessed via a bus (i2c, spi, ...). The bus access requires thread\ncontext. For such devices we need to keep the interrupt line masked\nuntil the threaded handler has executed.\n\nAdd a new flag IRQF_ONESHOT which allows drivers to request that the\ninterrupt is not unmasked after the hard interrupt context handler has\nbeen executed and the thread has been woken. The interrupt line is\nunmasked after the thread handler function has been executed.\n\nNote that for now IRQF_ONESHOT cannot be used with IRQF_SHARED to\navoid complex accounting mechanisms.\n\nFor oneshot interrupts the primary handler simply returns\nIRQ_WAKE_THREAD and does nothing else. A generic implementation\nirq_default_primary_handler() is provided to avoid useless copies all\nover the place. It is automatically installed when\nrequest_threaded_irq() is called with handler\u003dNULL and\nthread_fn!\u003dNULL.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Mark Brown \u003cbroonie@opensource.wolfsonmicro.com\u003e\nCc: Dmitry Torokhov \u003cdmitry.torokhov@gmail.com\u003e\nCc: Trilok Soni \u003csoni.trilok@gmail.com\u003e\nCc: Pavel Machek \u003cpavel@ucw.cz\u003e\nCc: Brian Swetland \u003cswetland@google.com\u003e\nCc: Joonyoung Shim \u003cjy0922.shim@samsung.com\u003e\nCc: m.szyprowski@samsung.com\nCc: t.fujak@samsung.com\nCc: kyungmin.park@samsung.com,\nCc: David Brownell \u003cdavid-b@pacbell.net\u003e\nCc: Daniel Ribeiro \u003cdrwyrm@gmail.com\u003e\nCc: arve@android.com\nCc: Barry Song \u003c21cnbao@gmail.com\u003e\n\n" }, { "commit": "612e900c286a9535cc17da5171b0d8dcf8f3a12f", "tree": "f6931d0c1bc6cf8f798e04437a1a9c3d59a4eea5", "parents": [ "c57c3743784e08d8ceaaea928a8c84ad8b403aed", "9ba5f005c994ad28e266a0cd14ef29354be382c9" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 22 10:12:18 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Jul 22 10:12:18 2009 -0700" }, "message": "Merge branch \u0027core-fixes-for-linus-2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027core-fixes-for-linus-2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n softirq: introduce tasklet_hrtimer infrastructure\n" }, { "commit": "9ba5f005c994ad28e266a0cd14ef29354be382c9", "tree": "0a2ff570070afc18e7dad61a2955b94614ce9b51", "parents": [ "aea1f7964ae6cba5eb419a958956deb9016b3341" ], "author": { "name": "Peter Zijlstra", "email": "peterz@infradead.org", "time": "Wed Jul 22 14:18:35 2009 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Jul 22 17:01:17 2009 +0200" }, "message": "softirq: introduce tasklet_hrtimer infrastructure\n\ncommit ca109491f (hrtimer: removing all ur callback modes) moved all\nhrtimer callbacks into hard interrupt context when high resolution\ntimers are active.

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. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does\n something different depending on whether it\u0027s been supplied with a regs\n pointer or not.\n\n (*) Various IRQ handler function pointers have been moved to type\n irq_handler_t.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)\n" }, { "commit": "da482792a6d1a3fbaaa25fae867b343fb4db3246", "tree": "138c187e669bbaf997780a999299fbc977568e1c", "parents": [ "57a58a9435aef3e0342ba4b2c97e0ddfea6f2c7f" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Thu Oct 05 13:06:34 2006 +0100" }, "committer": { "name": "David Howells", "email": "dhowells@warthog.cambridge.redhat.com", "time": "Thu Oct 05 13:28:27 2006 +0100" }, "message": "IRQ: Typedef the IRQ handler function type\n\nTypedef the IRQ handler function type.\n\nSigned-Off-By: David Howells \u003cdhowells@redhat.com\u003e\n(cherry picked from 1356d1e5fd256997e3d3dce0777ab787d0515c7a commit)\n" }, { "commit": "e8106b941ceab68cc5ff713df7b1276484554584", "tree": "6d8ad676796f4469aa334589565e971932049bc4", "parents": [ "6ea36ddbd1abfe867f1e874a8312bfd811e5fd2c" ], "author": { "name": "Arjan van de Ven", "email": "arjan@linux.intel.com", "time": "Fri Sep 29 02:01:08 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Sep 29 09:18:20 2006 -0700" }, "message": "[PATCH] lockdep: core, add enable/disable_irq_irqsave/irqrestore() APIs\n\nIntroduce the disable_irq_nosync_lockdep_irqsave() and\nenable_irq_lockdep_irqrestore() APIs.
