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 #
