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.

filling all\nthis info into the new addr_location struct, so that tools like\nannotate and report can further process the event by creating\nhist_entries in their specific way (with or without callgraphs,\netc).\n\nIt in turn uses the new next layer function:\n\n\tvoid thread__find_addr_location(struct thread *self, u8 cpumode,\n\t\t\t\t\tenum map_type type, u64 addr,\n\t\t\t\t\tstruct

near future) at the given cpumode, taking vdsos into\naccount (userspace hit, but kernel symbol) and will fill all\nthese details in the addr_location given.\n\nTools that need a more compact API for

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.

This causes compiler warnings every time we\nprint a __u64 value with %Lx.\n\nRather than changing __u64, we define our own u64 to be unsigned long\nlong on all architectures, and similarly s64 as signed long long.\nFor consistency we also define u32, s32, u16, s16, u8 and s8. These\ndefinitions are put in a new header, types.h, because these definitions\nare needed in util/string.h and util/symbol.h.\n\nThe main change here is the mechanical change of __[us]{64,32,16,8}\nto remove the \"__\". The other changes are:\n\n* Create types.h\n* Include types.h in perf.h, util/string.h and util/symbol.h\n* Add types.h to the LIB_H definition in Makefile\n* Added (u64) casts in process_overflow_event() and print_sym_table()\n to kill two remaining warnings.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: benh@kernel.crashing.org\nLKML-Reference: \u003c19003.33494.495844.956580@cargo.ozlabs.ibm.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "f4dbfa8f3131a84257223393905f7efad0ca5996", "tree": "67bb2666868c4449c2fa9ba6dc931721f60deb6c", "parents": [ "1c432d899d32d36371ee4ee310fa3609cf0e5742" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Thu Jun 11 14:06:28 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jun 11 17:54:15 2009 +0200" }, "message": "perf_counter: Standardize event names\n\nPure renames only, to PERF_COUNT_HW_* and PERF_COUNT_SW_*.\n\nSigned-off-by: 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\nLKML-Reference: \u003cnew-submission\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "729ff5e2aaf181f5d3ab849337fce406cd19b1d9", "tree": "49591d8103f05bd157c083b9392ed7f4a8b3ae17", "parents": [ "df58ab24bf26b166874bfb18b3b5a2e0a8e63179" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jun 11 14:16:15 2009 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Jun 11 16:48:38 2009 +0200" }, "message": "perf_counter tools: Clean up u64 usage\n\nA build error slipped in:\n\n builtin-report.c: In function ‘hist_entry__fprintf’:\n builtin-report.c:711: error: format ‘%12d’ expects type ‘int’, but argument 3 has type ‘uint64_t’\n\nBecause we got a bit sloppy with those types. uint64_t really sucks,\nbecause there\u0027s no printf format for it.
