self-descriptive (v8)\n\nThe goal of this patch is to include more information about the host\nenvironment into the perf.data so it is more self-descriptive. 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 # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n # captured on : Mon Sep 26 15:22:14 2011\n # hostname : quad\n # os release : 3.1.0-rc4-tip\n # perf version : 3.1.0-rc4\n # arch : x86_64\n # nrcpus online : 4\n # nrcpus avail : 4\n # cpudesc : Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz\n # cpuid : GenuineIntel,6,15,11\n # total memory : 8105360 kB\n # cmdline : /home/eranian/perfmon/official/tip/build/tools/perf/perf record date\n # event : name \u003d cycles, type \u003d 0, config \u003d 0x0, config1 \u003d 0x0, config2 \u003d 0x0, excl_usr \u003d 0, excl_kern \u003d 0, id \u003d { 29, 30, 31,\n # HEADER_CPU_TOPOLOGY info available, use -I to display\n # HEADER_NUMA_TOPOLOGY info available, use -I to display\n # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n #\n ...\n\n $ perf report --stdio -I\n # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n # captured on : Mon Sep 26 15:22:14 2011\n # hostname : quad\n # os release : 3.1.0-rc4-tip\n # perf version : 3.1.0-rc4\n # arch : x86_64\n # nrcpus online : 4\n # nrcpus avail : 4\n # cpudesc : Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz\n # cpuid : GenuineIntel,6,15,11\n # total memory : 8105360 kB\n # cmdline : /home/eranian/perfmon/official/tip/build/tools/perf/perf record date\n # event : name \u003d cycles, type \u003d 0, config \u003d 0x0, config1 \u003d 0x0, config2 \u003d 0x0, excl_usr \u003d 0, excl_kern \u003d 0, id \u003d { 29, 30, 31,\n # sibling cores : 0-3\n # sibling threads : 0\n # sibling threads : 1\n # sibling threads : 2\n # sibling threads : 3\n # node0 meminfo : total \u003d 8320608 kB, free \u003d 7571024 kB\n # node0 cpu list : 0-3\n # \u003d\u003d\u003d\u003d\u003d\u003d\u003d\u003d\n #\n ...\n\nReviewed-by: David Ahern \u003cdsahern@gmail.com\u003e\nTested-by: David Ahern \u003cdsahern@gmail.com\u003e\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Robert Richter \u003crobert.richter@amd.com\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nLink: http://lkml.kernel.org/r/20110930134040.GA5575@quad\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\n[ committer notes: Use --show-info in the tools as was in the docs, rename\n perf_header_fprintf_info to perf_file_section__fprintf_info, fixup\n conflict with f69b64f7 \"perf: Support setting the disassembler style\" ]\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "5d67be97f8903d05ce53597fb5f3bc25a45e8026", "tree": "5ce8c2407d50570d7fee79b9c7f24e8eb89384b4", "parents": [ "9f8b6a6cf0ee78de87ebe1e87f54bec1c1741ef7" ], "author": { "name": "Anton Blanchard", "email": "anton@samba.org", "time": "Mon Jul 04 21:57:50 2011 +1000" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Tue Jul 05 10:44:44 2011 +0200" }, "message": "perf report/annotate/script: Add option to specify a CPU range\n\nAdd an option to perf report/annotate/script to specify which\nCPUs to operate on.

I wanted to use -C to be\nconsistent with perf top/record/stat, but unfortunately perf\nreport already uses -C \u003ccomms\u003e.\n\n v2: Incorporate suggestions from David Ahern:\n\t- Added -c to perf script\n\t- Check that SAMPLE_CPU is set when -c is used\n\t- Update documentation\n\n v3: Create perf_session__cpu_bitmap()\n\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nAcked-by: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nLink: http://lkml.kernel.org/r/20110704215750.11647eb9@kryten\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "7cec0922389e080d11ec43dd23aa778e136bd1e1", "tree": "0d772b32f38b4ef16e4256711e947b38baa2c2f9", "parents": [ "610723f24eeb842025178a6722fa9108c4e157b6" ], "author": { "name": "David Ahern", "email": "dsahern@gmail.com", "time": "Mon May 30 13:08:23 2011 -0600" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Jun 02 13:31:01 2011 -0300" }, "message": "perf script: Add printing of sample address\n\nResolve to a function or variable if possible and if the sym option is\nenabled.\n\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nLink: http://lkml.kernel.org/r/1306782503-22002-1-git-send-email-dsahern@gmail.com\nSigned-off-by: David Ahern \u003cdsahern@gmail.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "610723f24eeb842025178a6722fa9108c4e157b6", "tree": "e184c3b2242ba9b9da065221d4673603dd9d8e86", "parents": [ "787bef174f055343c69a9639e6e05a564980ed4c" ], "author": { "name": "David Ahern", "email": "dsahern@gmail.com", "time": "Fri May 27 14:28:44 2011 -0600" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Thu Jun 02 13:29:14 2011 -0300" }, "message": "perf script: Make printing of dso a separate field option\n\nThe \u0027sym\u0027 option displays both the function name and the DSO it comes\nfrom.

commands.\n\nThe main change it makes is to allow \u003ccommands\u003e to be run as part of\nperf trace live-mode commands, as other perf commands do, instead of\nthe system-wide traces they\u0027re currently hard-coded to by the shell\nscripts.\n\nWith this patch, the following live-mode trace now works as expected:\n\n $ perf trace rw-by-pid ls -al\n\nThe previous system-wide behavior for this command would still be\navailable by explicitly specifying -a:\n\n $ perf trace rw-by-pid -a ls -al\n\nand if no \u003ccommand\u003e is specified, the output is also system-wide:\n\n $ perf trace rw-by-pid\n\nBecause live-mode requires both record and report steps to be invoked,\nit isn\u0027t always possible to know which args to send to the report and\nwhich to send to the record steps - mainly this is the case for report\nscripts with optional args - in those cases it would be necessary to\nuse separate \u0027perf trace record\u0027 and \u0027perf trace report\u0027 steps.\n\nFor example:\n\n $ perf trace syscall-counts ls\n\nHere we can\u0027t decide whether ls should be passed as a param to the\nsyscall-counts script or whether we should invoke ls as a \u003ccommand\u003e.\nIn these cases, we just say that we\u0027ll ignore optional script params\nand always interpret the extra arguments as a \u003ccommand\u003e.\n\nIf the user instead wants the other interpretation, that can be\naccomplished by using separate record and report commands explicitly:\n\n $ perf trace record syscall-counts\n $ perf trace report syscall-counts ls\n\nSo the rules that this patch implements, which seem to make the most\nintuitive sense for live-mode commands:\n\n- for commands with optional args and commands with no args, no args\n are sent to the report script, all are sent to the record step\n\n- for \u0027top\u0027 commands i.e. that end with \u0027top\u0027, \u003ccommands\u003e can\u0027t be\n used - all extra args are send to the report script as params\n\n- for commands with required args, the n required args are taken to be\n the first n args after the script name and sent to the report\n script, and the rest are sent to the record step\n\nSigned-off-by: Tom Zanussi \u003ctom.zanussi@linux.intel.com\u003e\nAcked-by: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\n" }, { "commit":

browser, I realised that it would be\nbetter to introduce a new class, \"hists\" (short for \"histograms\"),\nrenaming the \"event_stat_id\" struct and the perf_session methods that\nwere really \"hists\" methods, as they manipulate only struct hists\nmembers, not touching anything in the other perf_session members.\n\nOther optimizations, such as calculating the maximum lenght of a symbol\nname present in an hists instance will be possible as we add them,\navoiding a re-traversal just for finding that information.\n\nThe rationale for the name \"hists\" to replace \"event_stat_id\" is that we\nmay have multiple sets of hists for the same event_stat id, as, for\ninstance, the \u0027perf diff\u0027 tool has, so event stat id is not what\ncharacterizes what this struct and the functions that manipulate it do.\n\nCc: Eric B Munson \u003cebmunson@us.ibm.com\u003e\nCc: Frédéric Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Galbraith
