in perf\n\nWhile tracing using events with perf, if one enables the\nlockdep:lock_acquire event, it will infect every other perf\ntrace events.\n\nBasically, you can enable whatever set of trace events through\nperf but if this event is part of the set, the only result we\ncan get is a long list of lock_acquire events of rcu read lock,\nand only that.\n\nThis is because of a recursion inside perf.\n\n1) When a trace event is triggered, it will fill a per cpu\n buffer and submit it to perf.\n\n2) Perf will commit this event but will also protect some data\n using rcu_read_lock\n\n3) A recursion appears: rcu_read_lock triggers a lock_acquire\n event that will fill the per cpu event and then submit the\n buffer to perf.\n\n4) Perf detects a recursion and ignores it\n\n5) Perf continues its work on the previous event, but its buffer\n has been overwritten by the lock_acquire event, it has then\n been turned into a lock_acquire event of rcu read lock\n\nSuch scenario also happens with lock_release with\nrcu_read_unlock().\n\nWe could turn the rcu_read_lock() into __rcu_read_lock() to drop\nthe lock debugging from perf fast path, but that would make us\nlose the rcu

$ perf record -R -f -a -e irq:irq_handler_entry --filter handler\u003dtimer sleep 1\n Error: failed to set filter with 22 (Invalid argument)\n\nThe problem is that while an \u0027irq\u0027 field exists and is recognized\nas a filter field - \u0027handler\u0027 does not exist - its name is \u0027name\u0027\nin the output.\n\nTo solve this, we need to synchronize the printout and the field\nnames, wherever possible.\n\nIn cases where the printout prints a non-field, we enclose\nthat information in square brackets, such as:\n\n perf-1380 [013] 724.903505: softirq_exit: vec\u003d9 [action\u003dRCU]\n perf-1380 [013] 724.904482: softirq_exit: vec\u003d1 [action\u003dTIMER]\n\nThis way users can use filter expressions more intuitively: all\nfields that show up as \u0027primary\u0027 (non-bracketed) information is\nfilterable.\n\nThis patch harmonizes the field names for all irq, bkl, power,\nsched and timer events.\n\nWe might in fact think about dropping the print format bit of\ngeneric tracepoints altogether, and just print the fields that\nare being recorded.\n\nCc: Li Zefan \u003clizf@cn.fujitsu.com\u003e\nCc: Tom Zanussi

Fields are being reused for multiple purposes, and\n the whole message structure is limited and x86 specific to begin\n with.\n\nAll in one, the x86 tree would like to move away from this private\nimplementation of an event logging facility to a broader framework.\n\nBy using perf events we gain the following advantages:\n\n - Multiple user-space agents can access MCE events. We can have an\n mcelog daemon running but also a system-wide tracer capturing\n important events in flight-recorder mode.\n\n - Sampling support: the kernel and the user-space call-chain of MCE\n events can be stored and analyzed as well. This way actual patterns\n of bad behavior can be matched to precisely what kind of activity\n happened in the kernel (and/or in the app) around that moment in\n time.\n\n - Coupling with other hardware and software events: the PMU can track a\n number of other anomalies - monitoring software might chose to\n monitor those plus the MCE events as well - in one coherent stream of\n events.\n\n - Discovery of MCE sources - tracepoints are enumerated and tools can\n act upon the existence (or non-existence) of various channels of MCE\n information.\n\n - Filtering support: we just subscribe to and act upon the events we\n are interested in. Then even on a per event source basis there\u0027s\n in-kernel filter expressions available that can restrict the amount\n of data that hits the event channel.\n\n - Arbitrary deep per cpu buffering of events - we can buffer 32\n entries or we can buffer as much as we want, as long as we have\n the RAM.\n\n - An NMI-safe ring-buffer implementation - mappable to user-space.\n\n - Built-in support for timestamping of events, PID markers, CPU\n markers, etc.\n\n - A rich ABI accessible over system call interface. Per cpu, per task\n and per workload monitoring of MCE events can be done this way. The\n ABI itself has a nice, meaningful structure.\n\n - Extensible ABI: new fields can be added without breaking tooling.\n New tracepoints can be added as the hardware side evolves. There\u0027s\n various parsers that can be used.\n\n - Lots of scheduling/buffering/batching modes of operandi for MCE\n events. poll() support. mmap() support. read() support. You name it.\n\n - Rich tooling support: even without any MCE specific extensions added\n the \u0027perf\u0027 tool today offers various views of MCE data: perf report,\n perf stat, perf trace can all be used to view logged MCE events and\n perhaps correlate them to certain user-space usage patterns. But it\n can be used directly as well, for user-space agents and policy action\n in mcelog, etc.\n\nWith this we hope to achieve significant code cleanup and feature\nimprovements in the MCE code, and we hope to be able to drop the\n/dev/mcelog facility in the end.\n\nThis patch is just a plain dumb dump of mce_log() records to\nthe tracepoints / perf events framework - a first proof of\nconcept step.\n\nSigned-off-by: Hidetoshi Seto \u003cseto.hidetoshi@jp.fujitsu.com\u003e\nCc: Huang Ying \u003cying.huang@intel.com\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nLKML-Reference: \u003c4AD42A0D.7050104@jp.fujitsu.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "9dbdd6c41c12fb42ee7188eafa7e1917b192af3a", "tree": "06a9eb894bc976c5c20e84ccd74fd82b9b71aed4", "parents": [ "7a693d3f0d10f978ebdf3082c41404ab97106567", "161291396e76e0832c08f617eb9bd364d1648148" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 13 09:31:28 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 13 09:31:34 2009 +0200" }, "message": "Merge commit \u0027v2.6.32-rc4\u0027 into perf/core\n\nMerge reason: we were on an -rc1 base, merge up to -rc4.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "26a50744b21fff65bd754874072857bee8967f4d", "tree": "4819820f0841090232fcd2525f496f787fd411c7", "parents": [ "d9b2002c406011164f245de7a81304625989f1c9" ], "author": { "name": "Tom Zanussi", "email": "tzanussi@gmail.com", "time": "Tue Oct 06 01:09:50 2009 -0500" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Oct 06 15:04:45 2009 +0200" }, "message": "tracing/events: Add \u0027signed\u0027 field to format files\n\nThe sign info used for filters in the kernel is also useful to\napplications that process the trace stream.

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them.
