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": "19d4ac3c1039fb952f4c073fd0898e9295a836c8", "tree": "56acd6c60a518297713a5392acd8813cf4ef768a", "parents": [ "ab81f3fd350c510730adb1ca40ef55c2b2952121" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Wed Oct 05 19:30:22 2011 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri Oct 07 16:59:59 2011 -0300" }, "message": "perf top: Add callgraph support\n\nJust like in \u0027perf report\u0027, but live.\n\nStill needs to decay the callchains, but already somewhat useful as-is.\n\nCc: David Ahern \u003cdsahern@gmail.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Stephane Eranian \u003ceranian@google.com\u003e\nLink: http://lkml.kernel.org/n/tip-cj3rmaf5jpsvi3v0tf7t4uvp@git.kernel.org\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "ab81f3fd350c510730adb1ca40ef55c2b2952121", "tree": "7b442d9592dd5666eb2cae6194962e545bd693a7", "parents": [ "81cce8de9437be9234f651be1f03e596c1b1a79a" ], "author": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Wed Oct 05 19:16:15 2011 -0300" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri Oct 07 16:56:44 2011 -0300" }, "message": "perf top: Reuse the \u0027report\u0027 hist_entry/hists classes\n\nThis actually fixes several problems we had in the old \u0027perf top\u0027:\n\n1.

This makes it very easy\nto import counts directly into your favorite spreadsheet without having to\nwrite scripts.\n\nExample:\n$ perf stat --field-separator\u003d, -a -- sleep 1\n4009.961740,task-clock-msecs\n13,context-switches\n2,CPU-migrations\n189,page-faults\n9596385684,cycles\n3493659441,instructions\n872897069,branches\n41562,branch-misses\n22424,cache-references\n1289,cache-misses\n\nWorks also in non-aggregated mode:\n\n$ perf stat -x , -a -A -- sleep 1\nCPU0,1002.526168,task-clock-msecs\nCPU1,1002.528365,task-clock-msecs\nCPU2,1002.523360,task-clock-msecs\nCPU3,1002.519878,task-clock-msecs\nCPU0,1,context-switches\nCPU1,5,context-switches\nCPU2,5,context-switches\nCPU3,6,context-switches\nCPU0,0,CPU-migrations\nCPU1,1,CPU-migrations\nCPU2,0,CPU-migrations\nCPU3,1,CPU-migrations\nCPU0,2,page-faults\nCPU1,6,page-faults\nCPU2,9,page-faults\nCPU3,174,page-faults\nCPU0,2399439771,cycles\nCPU1,2380369063,cycles\nCPU2,2399142710,cycles\nCPU3,2373161192,cycles\nCPU0,872900618,instructions\nCPU1,873030960,instructions\nCPU2,872714525,instructions\nCPU3,874460580,instructions\nCPU0,221556839,branches\nCPU1,218134342,branches\nCPU2,218161730,branches\nCPU3,218284093,branches\nCPU0,18556,branch-misses\nCPU1,1449,branch-misses\nCPU2,3447,branch-misses\nCPU3,12714,branch-misses\nCPU0,8330,cache-references\nCPU1,313844,cache-references\nCPU2,47993728,cache-references\nCPU3,826481,cache-references\nCPU0,272,cache-misses\nCPU1,5360,cache-misses\nCPU2,1342193,cache-misses\nCPU3,13992,cache-misses\n\nThis second version adds the ability to name a separator and uses\nfield-separator as the long option to be consistent with perf report.\n\nCommiter note: Since we enabled --big-num by default in 201e0b0 and -x can\u0027t be\nused with it, we need to notice if the user explicitely enabled or disabled -B,\nadd code to disable big_num if the user didn\u0027t explicitely set --big_num when\n-x is used.\n\nCc: David S.

This option is not supported in per-thread mode.\n\nBeing able to get a per-cpu breakdown is useful to detect imbalances between\nCPUs when running a uniform workload than spans all monitored CPUs.\n\nThe second version corrects the missing cpumap[] support, so that it works when\nthe -C option is used.\n\nThe third version fixes a missing cpumap[] in print_counter() and removes a\nstray patch in builtin-trace.c.\n\nExamples on a 4-way system:\n\n# perf stat -a -e cycles,instructions -- sleep 1\n Performance counter stats for \u0027sleep 1\u0027:\n 9592808135 cycles\n 3490380006 instructions # 0.364 IPC\n 1.001584632 seconds time elapsed\n\n# perf stat -a -A -e cycles,instructions -- sleep 1\n Performance counter stats for \u0027sleep 1\u0027:\nCPU0 2398163767 cycles\nCPU1 2398180817 cycles\nCPU2 2398217115 cycles\nCPU3 2398247483 cycles\nCPU0 872282046 instructions # 0.364 IPC\nCPU1 873481776 instructions # 0.364 IPC\nCPU2 872638127 instructions # 0.364 IPC\nCPU3 872437789 instructions # 0.364 IPC\n 1.001556052 seconds time elapsed\n\nCc: David S.
