      "message": "rcu: Use softirq to address performance regression\n\nCommit a26ac2455ffcf3(rcu: move TREE_RCU from softirq to kthread)\nintroduced performance regression. In an AIM7 test, this commit degraded\nperformance by about 40%.\n\nThe commit runs rcu callbacks in a kthread instead of softirq. We observed\nhigh rate of context switch which is caused by this. Out test system has\n64 CPUs and HZ is 1000, so we saw more than 64k context switch per second\nwhich is caused by RCU\u0027s per-CPU kthread.  A trace showed that most of\nthe time the RCU per-CPU kthread doesn\u0027t actually handle any callbacks,\nbut instead just does a very small amount of work handling grace periods.\nThis means that RCU\u0027s per-CPU kthreads are making the scheduler do quite\na bit of work in order to allow a very small amount of RCU-related\nprocessing to be done.\n\nAlex Shi\u0027s analysis determined that this slowdown is due to lock\ncontention within the scheduler.  Unfortunately, as Peter Zijlstra points\nout, the scheduler\u0027s real-time semantics require global action, which\nmeans that this contention is inherent in real-time scheduling.  (Yes,\nperhaps someone will come up with a workaround -- otherwise, -rt is not\ngoing to do well on large SMP systems -- but this patch will work around\nthis issue in the meantime.  And \"the meantime\" might well be forever.)\n\nThis patch therefore re-introduces softirq processing to RCU, but only\nfor core RCU work.  RCU callbacks are still executed in kthread context,\nso that only a small amount of RCU work runs in softirq context in the\ncommon case.  This should minimize ksoftirqd execution, allowing us to\nskip boosting of ksoftirqd for CONFIG_RCU_BOOST\u003dy kernels.\n\nSigned-off-by: Shaohua Li \u003cshaohua.li@intel.com\u003e\nTested-by: \"Alex,Shi\" \u003calex.shi@intel.com\u003e\nSigned-off-by: Paul E.

      "message": "block: add blk-iopoll, a NAPI like approach for block devices\n\nThis borrows some code from NAPI and implements a polled completion\nmode for block devices. The idea is the same as NAPI - instead of\ndoing the command completion when the irq occurs, schedule a dedicated\nsoftirq in the hopes that we will complete more IO when the iopoll\nhandler is invoked. Devices have a budget of commands assigned, and will\nstay in polled mode as long as they continue to consume their budget\nfrom the iopoll softirq handler. If they do not, the device is set back\nto interrupt completion mode.\n\nThis patch holds the core bits for blk-iopoll, device driver support\nsold separately.\n\nSigned-off-by: Jens Axboe \u003cjens.axboe@oracle.com\u003e\n"

      "message": "genirq: Add oneshot support\n\nFor threaded interrupt handlers we expect the hard interrupt handler\npart to mask the interrupt on the originating device. 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"

      "message": "PM: Introduce functions for suspending and resuming device interrupts\n\nIntroduce helper functions allowing us to prevent device drivers from\ngetting any interrupts (without disabling interrupts on the CPU)\nduring suspend (or hibernation) and to make them start to receive\ninterrupts again during the subsequent resume.  These functions make it\npossible to keep timer interrupts enabled while the \"late\" suspend and\n\"early\" resume callbacks provided by device drivers are being\nexecuted.  In turn, this allows device drivers\u0027 \"late\" suspend and\n\"early\" resume callbacks to sleep, execute ACPI callbacks etc.\n\nThe functions introduced here will be used to rework the handling of\ninterrupts during suspend (hibernation) and resume.  Namely,\ninterrupts will only be disabled on the CPU right before suspending\nsysdevs, while device drivers will be prevented from receiving\ninterrupts, with the help of the new helper function, before their\n\"late\" suspend callbacks run (and analogously during resume).\n\nSigned-off-by: Rafael J.

      "message": "genirq: add threaded interrupt handler support\n\nAdd support for threaded interrupt handlers:\n\nA device driver can request that its main interrupt handler runs in a\nthread. To achive this the device driver requests the interrupt with\nrequest_threaded_irq() and provides additionally to the handler a\nthread function. The handler function is called in hard interrupt\ncontext and needs to check whether the interrupt originated from the\ndevice. If the interrupt originated from the device then the handler\ncan either return IRQ_HANDLED or IRQ_WAKE_THREAD. IRQ_HANDLED is\nreturned when no further action is required. IRQ_WAKE_THREAD causes\nthe genirq code to invoke the threaded (main) handler. When\nIRQ_WAKE_THREAD is returned handler must have disabled the interrupt\non the device level. This is mandatory for shared interrupt handlers,\nbut we need to do it as well for obscure x86 hardware where disabling\nan interrupt on the IO_APIC level redirects the interrupt to the\nlegacy PIC interrupt lines.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nReviewed-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n\n"

      "message": "sparse irq_desc[] array: core kernel and x86 changes\n\nImpact: new feature\n\nProblem on distro kernels: irq_desc[NR_IRQS] takes megabytes of RAM with\nNR_CPUS set to large values. The goal is to be able to scale up to much\nlarger NR_IRQS value without impacting the (important) common case.\n\nTo solve this, we generalize irq_desc[NR_IRQS] to an (optional) array of\nirq_desc pointers.\n\nWhen CONFIG_SPARSE_IRQ\u003dy is used, we use kzalloc_node to get irq_desc,\nthis also makes the IRQ descriptors NUMA-local (to the site that calls\nrequest_irq()).\n\nThis gets rid of the irq_cfg[] static array on x86 as well: irq_cfg now\nuses desc-\u003echip_data for x86 to store irq_cfg.\n\nSigned-off-by: Yinghai Lu \u003cyinghai@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

      "message": "hrtimer: removing all ur callback modes\n\nImpact: cleanup, move all hrtimer processing into hardirq context\n\nThis is an attempt at removing some of the hrtimer complexity by\nreducing the number of callback modes to 1.\n\nThis means that all hrtimer callback functions will be ran from HARD-irq\ncontext.\n\nI went through all the 30 odd hrtimer callback functions in the kernel\nand saw only one that I\u0027m not quite sure of, which is the one in\nnet/can/bcm.c - hence I\u0027m CC-ing the folks responsible for that code.\n\nFurthermore, the hrtimer core now calls callbacks directly with IRQs\ndisabled in case you try to enqueue an expired timer. If this timer is a\nperiodic timer (which should use hrtimer_forward() to advance its time)\nthen it might be possible to end up in an inf. recursive loop due to the\nfact that hrtimer_forward() doesn\u0027t round up to the next timer\ngranularity, and therefore keeps on calling the callback - obviously\nthis needs a fix.\n\nAside from that, this seems to compile and actually boot on my dual core\ntest box - although I\u0027m sure there are some bugs in, me not hitting any\nmakes me certain :-)\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

For example, I have code using stop machine to do ECC error\ninjection, used to verify operations of the ECC hardware, that sort of thing.\nIt really needs to make sure that nothing is actually writing to memory while\nthe injection happens.  Similar examples can be found in other low level bits\nand pieces.\n\nThis patch implements a generic hard_irq_disable() function which is meant to\nbe called -after- local_irq_disable() and ensures that interrupts are fully\ndisabled on that CPU.
