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 #

If add a comparison by sample type to sort__sym_cmp we get the\nreal picture:\n\n...\n 57.11% [.] 0x80fbf63c\n 4.43% [k] ._spin_lock_irqsave\n 1.07% [k] ._spin_lock\n 0.65% [H] 0x33d43c\n\nSo it was almost all userspace, not hypervisor as the initial profile\nsuggested.\n\nI found another issue while adding this. Symbol sorting sometimes shows\nmultiple entries for the unknown bucket:\n\n...\n 16.65% [.] 0x6cd3a8\n 7.25% [.] 0x422460\n 5.37% [.] yylex\n 4.79% [.] malloc\n 4.78% [.] _int_malloc\n 4.03% [.] _int_free\n 3.95% [.] hash_source_code_string\n 2.82% [.] 0x532908\n 2.64% [.] 0x36b538\n 0.94% [H] 0x8000000000e132a4\n 0.82% [H] 0x800000000000e8b0\n\nThis happens because we aren\u0027t consistent with our sorting. On\none hand we check to see if both symbols match and for two unresolved\nsamples sym is NULL so we match:\n\n if (left-\u003ems.sym \u003d\u003d right-\u003ems.sym)\n return 0;\n\nOn the other hand we use sample IP for unresolved samples when\ncomparing against a symbol:\n\n ip_l \u003d left-\u003ems.sym ? left-\u003ems.sym-\u003estart : left-\u003eip;\n ip_r \u003d right-\u003ems.sym ? right-\u003ems.sym-\u003estart : right-\u003eip;\n\nThis means unresolved samples end up spread across the rbtree and we\ncan\u0027t merge them all.\n\nIf we use cmp_null all unresolved samples will end up in the one bucket\nand the output makes more sense:\n\n...\n 39.12% [.] 0x36b538\n 5.37% [.] yylex\n 4.79% [.] malloc\n 4.78% [.] _int_malloc\n 4.03% [.] _int_free\n 3.95% [.] hash_source_code_string\n 2.26% [H] 0x800000000000e8b0\n\nAcked-by: Eric B Munson \u003cemunson@mgebm.net\u003e\nCc: Eric B Munson \u003cemunson@mgebm.net\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Ian Munsie \u003cimunsie@au1.ibm.com\u003e\nLink: http://lkml.kernel.org/r/20110831115145.4f598ab2@kryten\nSigned-off-by: Anton Blanchard \u003canton@samba.org\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n" }, { "commit": "6a0e55d85babfccfd976703852ec8bab388b3a10", "tree": "965a6075c05d2600c50508b1dba4a0a7c5606614", "parents": [ "764e16a30a77a9c8346fbae6615e7c818ce9d00f" ], "author": { "name": "Anton Blanchard", "email": "anton@samba.org", "time": "Tue Aug 30 09:15:06 2011 +1000" }, "committer": { "name": "Arnaldo Carvalho de Melo", "email": "acme@redhat.com", "time": "Fri Sep 23 14:37:06 2011 -0300" }, "message": "perf symbols: Synthesize anonymous mmap events\n\nperf_event__synthesize_mmap_events does not create anonymous mmap events\neven though the kernel does.
