      "message": "perf tools: Fix sparse CPU numbering related bugs\n\nAt present, the perf subcommands that do system-wide monitoring\n(perf stat, perf record and perf top) don\u0027t work properly unless\nthe online cpus are numbered 0, 1, ..., N-1.  These tools ask\nfor the number of online cpus with sysconf(_SC_NPROCESSORS_ONLN)\nand then try to create events for cpus 0, 1, ..., N-1.\n\nThis creates problems for systems where the online cpus are\nnumbered sparsely.  For example, a POWER6 system in\nsingle-threaded mode (i.e. only running 1 hardware thread per\ncore) will have only even-numbered cpus online.\n\nThis fixes the problem by reading the /sys/devices/system/cpu/online\nfile to find out which cpus are online.  The code that does that is in\ntools/perf/util/cpumap.[ch], and consists of a read_cpu_map()\nfunction that sets up a cpumap[] array and returns the number of\nonline cpus.  If /sys/devices/system/cpu/online can\u0027t be read or\ncan\u0027t be parsed successfully, it falls back to using sysconf to\nask how many cpus are online and sets up an identity map in cpumap[].\n\nThe perf record, perf stat and perf top code then calls\nread_cpu_map() in the system-wide monitoring case (instead of\nsysconf) and uses cpumap[] to get the cpu numbers to pass to\nperf_event_open.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Anton Blanchard \u003canton@samba.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@infradead.org\u003e\nLKML-Reference: \u003c20100310093609.GA3959@brick.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\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.

      "message": "perf: Enable more compiler warnings\n\nRelated to a shadowed variable bug fix Valdis Kletnieks noticed\nthat perf does not get built with -Wshadow, which could have\nhelped us avoid the bug.\n\nSo enable -Wshadow and also enable the following warnings on\nperf builds, in addition to the already enabled -Wall -Wextra\n-std\u003dgnu99 warnings:\n\n -Wcast-align\n -Wformat\u003d2\n -Wshadow\n -Winit-self\n -Wpacked\n -Wredundant-decls\n -Wstack-protector\n -Wstrict-aliasing\u003d3\n -Wswitch-default\n -Wswitch-enum\n -Wno-system-headers\n -Wundef\n -Wvolatile-register-var\n -Wwrite-strings\n -Wbad-function-cast\n -Wmissing-declarations\n -Wmissing-prototypes\n -Wnested-externs\n -Wold-style-definition\n -Wstrict-prototypes\n -Wdeclaration-after-statement\n\nAnd change/fix the perf code to build cleanly under GCC 4.3.2.\n\nThe list of warnings enablement is rather arbitrary: it\u0027s based\non my (quick) reading of the GCC manpages and trying them on\nperf.\n\nI categorized the warnings based on individually enabling them\nand looking whether they trigger something in the perf build.\nIf i liked those warnings (i.e. if they trigger for something\nthat arguably could be improved) i enabled the warning.\n\nIf the warnings seemed to come from language laywers spamming\nthe build with tons of nuisance warnings i generally kept them\noff. Most of the sign conversion related warnings were in\nthis category. (A second patch enabling some of the sign\nwarnings might be welcome - sign bugs can be nasty.)\n\nI also kept warnings that seem to make sense from their manpage\ndescription and which produced no actual warnings on our code\nbase. These warnings might still be turned off if they end up\nbeing a nuisance.\n\nI also left out a few warnings that are not supported in older\ncompilers.\n\n[ Note that these changes might break the build on older\n  compilers i did not test, or on non-x86 architectures that\n  produce different warnings, so more testing would be welcome. ]\n\nReported-by: Valdis.Kletnieks@vt.edu\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nLKML-Reference: \u003cnew-submission\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
