This\nrequeuing is carried out by rcu_preempt_offline_tasks().\nHowever, it is possible that these queued tasks are the only\nthing preventing the leaf rcu_node structure from reporting a\nquiescent state up the rcu_node hierarchy. Unfortunately, the\nold code would fail to do this reporting, resulting in a\ngrace-period stall given the following sequence of events:\n\n1.\tKernel built for more than 32 CPUs on 32-bit systems or for more\n\tthan 64 CPUs on 64-bit systems, so that there is more than one\n\trcu_node structure. (Or CONFIG_RCU_FANOUT is artificially set\n\tto a number smaller than CONFIG_NR_CPUS.)\n\n2.\tThe kernel is built with CONFIG_TREE_PREEMPT_RCU.\n\n3.\tA task running on a CPU associated with a given leaf rcu_node\n\tstructure blocks while in an RCU read-side critical section\n\t-and- that CPU has not yet passed through a quiescent state\n\tfor the current RCU grace period. This will cause the task\n\tto be queued on the leaf rcu_node\u0027s blocked_tasks[] array, in\n\tparticular, on the element of this array corresponding to the\n\tcurrent grace period.\n\n4.\tEach of the remaining CPUs corresponding to this same leaf rcu_node\n\tstructure pass through a quiescent state. However, the task is\n\tstill in its RCU read-side critical section, so these quiescent\n\tstates cannot be reported further up the rcu_node hierarchy.\n\tNevertheless, all bits in the leaf rcu_node structure\u0027s -\u003eqsmask\n\tfield are now zero.\n\n5.\tEach of the remaining CPUs go offline. (The events in step\n\t#4 and #5 can happen in any order as long as each CPU passes\n\tthrough a quiescent state before going offline.)\n\n6.\tWhen the last CPU goes offline, __rcu_offline_cpu() will invoke\n\trcu_preempt_offline_tasks(), which will move the task to the\n\troot rcu_node structure, but without reporting a quiescent state\n\tup the rcu_node hierarchy (and this failure to report a quiescent\n\tstate is the bug).\n\n\tBut because this leaf rcu_node structure\u0027s -\u003eqsmask field is\n\talready zero and its -\u003eblock_tasks[] entries are all empty,\n\tforce_quiescent_state() will skip this rcu_node structure.\n\n\tTherefore, grace periods are now hung.\n\nThis patch abstracts some code out of rcu_read_unlock_special(),\ncalling the result task_quiet() by analogy with cpu_quiet(), and\ninvokes task_quiet() from both rcu_read_lock_special() and\n__rcu_offline_cpu(). Invoking task_quiet() from\n__rcu_offline_cpu() reports the quiescent state up the rcu_node\nhierarchy, fixing the bug. This ends up requiring a separate\nlock_class_key per level of the rcu_node hierarchy, which this\npatch also provides.\n\nSigned-off-by: Paul E.

If CPU 0\u0027s\n\tupdate prevails, later calls to force_quiescent_state() can\n\tcount old quiescent states against the new grace period, which\n\tcan in turn result in premature ending of grace periods.\n\n\tNot good.\n\nThis patch adds an RCU_GP_IDLE state for rsp-\u003esignaled that is\nset initially at boot time and any time a grace period ends.\nThis prevents CPU 0 from getting into the workings of\nforce_quiescent_state() in step 4. Additional locking and\nchecks prevent the concurrent update of rsp-\u003esignaled in step 6.\n\nSigned-off-by: Paul E.

timers: Check for pending timers after (device) interrupts\n\nNow that range timers and deferred timers are common, I found a\nproblem with these using the \"perf timechart\" tool. Frans Pop also\nreported high scheduler latencies via LatencyTop, when using\niwlagn.\n\nIt turns out that on x86, these two \u0027opportunistic\u0027 timers only get\nchecked when another \"real\" timer happens. These opportunistic\ntimers have the objective to save power by hitchhiking on other\nwakeups, as to avoid CPU wakeups by themselves as much as possible.\n\nThe change in this patch runs this check not only at timer\ninterrupts, but at all (device) interrupts. The effect is that:\n\n 1) the deferred timers/range timers get delayed less\n\n 2) the range timers cause less wakeups by themselves because\n the percentage of hitchhiking on existing wakeup events goes up.\n\nI\u0027ve verified the working of the patch using \"perf timechart\", the\noriginal exposed bug is gone with this patch. Frans also reported\nsuccess - the latencies are now down in the expected ~10 msec\nrange.\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nTested-by: Frans Pop \u003celendil@planet.nl\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nLKML-Reference: \u003c20091008064041.67219b13@infradead.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "2dca6999eed58d44b67e9de7d6ec230f6250553d", "tree": "6b6f1e2c07291fba968e6a72c095ca6526be88d5", "parents": [ "906010b2134e14a2e377decbadd357b3d0ab9c6a" ], "author": { "name": "David Miller", "email": "davem@davemloft.net", "time": "Mon Sep 21 12:22:34 2009 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Oct 08 17:02:31 2009 +0200" }, "message": "mm, perf_event: Make vmalloc_user() align base kernel virtual address to SHMLBA\n\nWhen a vmalloc\u0027d area is mmap\u0027d into userspace, some kind of\nco-ordination is necessary for this to work on platforms with cpu\nD-caches which can have aliases.\n\nOtherwise kernel side writes won\u0027t be seen properly in userspace\nand vice versa.\n\nIf the kernel side mapping and the user side one have the same\nalignment, modulo SHMLBA, this can work as long as VM_SHARED is\nshared of VMA and for all current users this is true. VM_SHARED\nwill force SHMLBA alignment of the user side mmap on platforms with\nD-cache aliasing matters.\n\nThe bulk of this patch is just making it so that a specific\nalignment can be passed down into __get_vm_area_node().
