As previously discussed this can cause issues when an event\ntriggered another NMI but is processed in the current NMI. This causes the\nnext NMI to go unprocessed and become an \u0027unknown\u0027 NMI.\n\nTo handle this, we first have to flag whether or not the NMI handler handled\nmore than one event or not. If it did, then there exists a chance that\nthe next NMI might be already processed. Once the NMI is flagged as a\ncandidate to be swallowed, we next look for a back-to-back NMI condition.\n\nThis is determined by looking at the %rip from pt_regs. If it is the same\nas the previous NMI, it is assumed the cpu did not have a chance to jump\nback into a non-NMI context and execute code and instead handled another NMI.\n\nIf both of those conditions are true then we will swallow any unknown NMI.\n\nThere still exists a chance that we accidentally swallow a real unknown NMI,\nbut for now things seem better.\n\nAn optimization has also been added to the nmi notifier rountine. Because x86\ncan latch up to one NMI while currently processing an NMI, we don\u0027t have to\nworry about executing _all_ the handlers in a standalone NMI. The idea is\nif multiple NMIs come in, the second NMI will represent them. For those\nback-to-back NMI cases, we have the potentail to drop NMIs.

This worked\ngreat until we wanted to support handling multiple events better.\n\nOne of the key ideas to the nmi handling is to process _all_ the handlers for\neach NMI. The reason behind this switch is because NMIs are edge triggered.\nIf enough NMIs are triggered, then they could be lost because the cpu can\nonly latch at most one NMI (besides the one currently being processed).\n\nIn order to deal with this we have decided to process all the NMI handlers\nfor each NMI. This allows the handlers to determine if they recieved an\nevent or not (the ones that can not determine this will be left to fend\nfor themselves on the unknown NMI list).\n\nAs a result of this change it is now possible to have an extra NMI that\nwas destined to be received for an already processed event. Because the\nevent was processed in the previous NMI, this NMI gets dropped and becomes\nan \u0027unknown\u0027 NMI. This of course will cause printks that scare people.\n\nHowever, we prefer to have extra NMIs as opposed to losing NMIs and as such\nare have developed a basic mechanism to catch most of them. That will be\na later patch.\n\nTo accomplish this idea, I unhooked the nmi handlers from the notifier\nroutines and created a new mechanism loosely based on doIRQ. The reason\nfor this is the notifier routines have a couple of shortcomings. One we\ncould\u0027t guarantee all future NMI handlers used NOTIFY_OK instead of\nNOTIFY_STOP. Second, we couldn\u0027t keep track of the number of events being\nhandled in each routine (most only handle one, perf can handle more than one).\nThird, I wanted to eventually display which nmi handlers are registered in\nthe system in /proc/interrupts to help see who is generating NMIs.\n\nThe patch below just implements the new infrastructure but doesn\u0027t wire it up\nyet (that is the next patch). Its design is based on doIRQ structs and the\natomic notifier routines. So the rcu stuff in the patch isn\u0027t entirely untested\n(as the notifier routines have soaked it) but it should be double checked in\ncase I copied the code wrong.\n\nSigned-off-by: Don Zickus \u003cdzickus@redhat.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLink: http://lkml.kernel.org/r/1317409584-23662-3-git-send-email-dzickus@redhat.com\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "1d48922c14b6363f6d5febb12464d804bb5cc53f", "tree": "2b2745b43b5edcdf1c65d4f0f6c141104468b36b", "parents": [ "144d31e6f1902a39bc95754d820d356722697850" ], "author": { "name": "Don Zickus", "email": "dzickus@redhat.com", "time": "Fri Sep 30 15:06:19 2011 -0400" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Oct 10 06:56:47 2011 +0200" }, "message": "x86, nmi: Split out nmi from traps.c\n\nThe nmi stuff is changing a lot and adding more functionality.

Overtime,\nprofiles are captured on various machines and it becomes hard to track\nwhat was recorded, on what machine and when.\n\nThis patch provides a way to solve this by extending the perf.data file\nwith basic information about the host machine. To add those extensions,\nwe leverage the feature bits capabilities of the perf.data format. The\nchange is backward compatible with existing perf.data files.\n\nWe define the following useful new extensions:\n - HEADER_HOSTNAME: the hostname\n - HEADER_OSRELEASE: the kernel release number\n - HEADER_ARCH: the hw architecture\n - HEADER_CPUDESC: generic CPU description\n - HEADER_NRCPUS: number of online/avail cpus\n - HEADER_CMDLINE: perf command line\n - HEADER_VERSION: perf version\n - HEADER_TOPOLOGY: cpu topology\n - HEADER_EVENT_DESC: full event description (attrs)\n - HEADER_CPUID: easy-to-parse low level CPU identication\n\nThe small granularity for the entries is to make it easier to extend\nwithout breaking backward compatiblity. Many entries are provided as\nASCII strings.\n\nPerf report/script have been modified to print the basic information as\neasy-to-parse ASCII strings. Extended information about CPU and NUMA\ntopology may be requested with the -I option.\n\nThanks to David Ahern for reviewing and testing the many versions of\nthis patch.\n\n $ perf report --stdio\n #

The\nintroduction of socket queue overflow reporting [1] changed drop\nrate calculation in the normal packet socket path, but not when using a\npacket ring. As a result, the getsockopt now returns different statistics\ndepending on the reception method used. With a ring, it still returns the\ncount since the last call, as counts are incremented in tpacket_rcv and\nreset in getsockopt. Without a ring, it returns 0 if no drops occurred\nsince the last getsockopt and the total drops over the lifespan of\nthe socket otherwise. The culprit is this line in packet_rcv, executed\non a drop:\n\ndrop_n_acct:\n po-\u003estats.tp_drops \u003d atomic_inc_return(\u0026sk-\u003esk_drops);\n\nAs it shows, the new drop number it taken from the socket drop counter,\nwhich is not reset at getsockopt. I put together a small example\nthat demonstrates the issue [2]. It runs for 10 seconds and overflows\nthe queue/ring on every odd second. The reported drop rates are:\nring: 16, 0, 16, 0, 16, ...\nnon-ring: 0, 15, 0, 30, 0, 46, 0, 60, 0 , 74.\n\nNote how the even ring counts monotonically increase. Because the\ngetsockopt adds tp_drops to tp_packets, total counts are similarly\nreported cumulatively. Long story short, reinstating the original code, as\nthe below patch does, fixes the issue at the cost of additional per-packet\ncycles. Another solution that does not introduce per-packet overhead\nis be to keep the current data path, record the value of sk_drops at\ngetsockopt() at call N in a new field in struct packetsock and subtract\nthat when reporting at call N+1. I\u0027ll be happy to code that, instead,\nit\u0027s just more messy.\n\n[1] http://patchwork.ozlabs.org/patch/35665/\n[2] http://kernel.googlecode.com/files/test-packetsock-getstatistics.c\n\nSigned-off-by: Willem de Bruijn \u003cwillemb@google.com\u003e\nSigned-off-by: David S.

It turns out it\u0027s because we were doing a short write on a not\nuptodate page, which means we\u0027d fall back at one page at a time and fault the\npage in. The problem is our position is on the page boundary, so our fault in\nlogic wasn\u0027t actually reading the page, so we\u0027d just spin forever or until the\npage got read in by somebody else. This will force a readpage if we end up\ndoing a short copy. Alexandre could reproduce this easily with ceph and reports\nit fixes his problem.

This breaks graphics on those\nmachines among others.\n\nThis fixes it using a quirk which copies the node pointer from the host\nbridge for the root complex, which makes the generic code work for the\nchildren afterward.\n\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b0f84374b6ab0dc9c47975df0b02d46165d558d4", "tree": "57e9d9bee80c89c92265df75aa579222b994b38f", "parents": [ "d5767c53535ac79758084773418e0ad186aba4a2" ], "author": { "name": "wangyanqing", "email": "udknight@gmail.com", "time": "Thu Sep 29 15:09:40 2011 +0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Sep 29 19:21:01 2011 -0700" }, "message": "bootup: move \u0027usermodehelper_enable()\u0027 a little earlier\n\nCommit d5767c53535a (\"bootup: move \u0027usermodehelper_enable()\u0027 to the end\nof do_basic_setup()\") moved \u0027usermodehelper_enable()\u0027 to end of\ndo_basic_setup() to after the initcalls.

users to get\nreports of dropped frames communicated to them via a netlink socket.\n\nWhile useful, several people have now asked that I integrate the ability\nto do drop monitoring with perf, so they don\u0027t have to run additional\ntools.\n\nThis patch adds a drop monitor script to the perf suite, and provides\nthe same output that the netlink socket does.\n\nCc: Ingo Molnar
