      "message": "Merge branch \u0027perf-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull perf events changes for v3.4 from Ingo Molnar:\n\n - New \"hardware based branch profiling\" feature both on the kernel and\n   the tooling side, on CPUs that support it.  (modern x86 Intel CPUs\n   with the \u0027LBR\u0027 hardware feature currently.)\n\n   This new feature is basically a sophisticated \u0027magnifying glass\u0027 for\n   branch execution - something that is pretty difficult to extract from\n   regular, function histogram centric profiles.\n\n   The simplest mode is activated via \u0027perf record -b\u0027, and the result\n   looks like this in perf report:\n\n\t$ perf record -b any_call,u -e cycles:u branchy\n\n\t$ perf report -b --sort\u003dsymbol\n\t    52.34%  [.] main                   [.] f1\n\t    24.04%  [.] f1                     [.] f3\n\t    23.60%  [.] f1                     [.] f2\n\t     0.01%  [k] _IO_new_file_xsputn    [k] _IO_file_overflow\n\t     0.01%  [k] _IO_vfprintf_internal  [k] _IO_new_file_xsputn\n\t     0.01%  [k] _IO_vfprintf_internal  [k] strchrnul\n\t     0.01%  [k] __printf               [k] _IO_vfprintf_internal\n\t     0.01%  [k] main                   [k] __printf\n\n   This output shows from/to branch columns and shows the highest\n   percentage (from,to) jump combinations - i.e.  the most likely taken\n   branches in the system.  \"branches\" can also include function calls\n   and any other synchronous and asynchronous transitions of the\n   instruction pointer that are not \u0027next instruction\u0027 - such as system\n   calls, traps, interrupts, etc.\n\n   This feature comes with (hopefully intuitive) flat ascii and TUI\n   support in perf report.\n\n - Various \u0027perf annotate\u0027 visual improvements for us assembly junkies.\n   It will now recognize function calls in the TUI and by hitting enter\n   you can follow the call (recursively) and back, amongst other\n   improvements.\n\n - Multiple threads/processes recording support in perf record, perf\n   stat, perf top - which is activated via a comma-list of PIDs:\n\n\tperf top -p 21483,21485\n\tperf stat -p 21483,21485 -ddd\n\tperf record -p 21483,21485\n\n - Support for per UID views, via the --uid paramter to perf top, perf\n   report, etc.  For example \u0027perf top --uid mingo\u0027 will only show the\n   tasks that I am running, excluding other users, root, etc.\n\n - Jump label restructurings and improvements - this includes the\n   factoring out of the (hopefully much clearer) include/linux/static_key.h\n   generic facility:\n\n\tstruct static_key key \u003d STATIC_KEY_INIT_FALSE;\n\n\t...\n\n\tif (static_key_false(\u0026key))\n\t        do unlikely code\n\telse\n\t        do likely code\n\n\t...\n\tstatic_key_slow_inc();\n\t...\n\tstatic_key_slow_inc();\n\t...\n\n   The static_key_false() branch will be generated into the code with as\n   little impact to the likely code path as possible.  the\n   static_key_slow_*() APIs flip the branch via live kernel code patching.\n\n   This facility can now be used more widely within the kernel to\n   micro-optimize hot branches whose likelihood matches the static-key\n   usage and fast/slow cost patterns.\n\n - SW function tracer improvements: perf support and filtering support.\n\n - Various hardenings of the perf.data ABI, to make older perf.data\u0027s\n   smoother on newer tool versions, to make new features integrate more\n   smoothly, to support cross-endian recording/analyzing workflows\n   better, etc.\n\n - Restructuring of the kprobes code, the splitting out of \u0027optprobes\u0027,\n   and a corner case bugfix.\n\n - Allow the tracing of kernel console output (printk).\n\n - Improvements/fixes to user-space RDPMC support, allowing user-space\n   self-profiling code to extract PMU counts without performing any\n   system calls, while playing nice with the kernel side.\n\n - \u0027perf bench\u0027 improvements\n\n - ... and lots of internal restructurings, cleanups and fixes that made\n   these features possible.  And, as usual this list is incomplete as\n   there were also lots of other improvements\n\n* \u0027perf-core-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (120 commits)\n  perf report: Fix annotate double quit issue in branch view mode\n  perf report: Remove duplicate annotate choice in branch view mode\n  perf/x86: Prettify pmu config literals\n  perf report: Enable TUI in branch view mode\n  perf report: Auto-detect branch stack sampling mode\n  perf record: Add HEADER_BRANCH_STACK tag\n  perf record: Provide default branch stack sampling mode option\n  perf tools: Make perf able to read files from older ABIs\n  perf tools: Fix ABI compatibility bug in print_event_desc()\n  perf tools: Enable reading of perf.data files from different ABI rev\n  perf: Add ABI reference sizes\n  perf report: Add support for taken branch sampling\n  perf record: Add support for sampling taken branch\n  perf tools: Add code to support PERF_SAMPLE_BRANCH_STACK\n  x86/kprobes: Split out optprobe related code to kprobes-opt.c\n  x86/kprobes: Fix a bug which can modify kernel code permanently\n  x86/kprobes: Fix instruction recovery on optimized path\n  perf: Add callback to flush branch_stack on context switch\n  perf: Disable PERF_SAMPLE_BRANCH_* when not supported\n  perf/x86: Add LBR software filter support for Intel CPUs\n  ...\n"

      "message": "perf tools: Make perf.data more 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"

      "message": "perf: Do the big rename: Performance Counters -\u003e Performance Events\n\nBye-bye Performance Counters, welcome Performance Events!\n\nIn the past few months the perfcounters subsystem has grown out its\ninitial role of counting hardware events, and has become (and is\nbecoming) a much broader generic event enumeration, reporting, logging,\nmonitoring, analysis facility.\n\nNaming its core object \u0027perf_counter\u0027 and naming the subsystem\n\u0027perfcounters\u0027 has become more and more of a misnomer. 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. I\u0027ve undone some of that, but\n  in case there\u0027s something left where \u0027counter\u0027 would be\n  better than \u0027event\u0027 we can undo that on an individual basis\n  instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.
