tools\n\nNow we have a very high level routine for simple tools to\nprocess IP sample events:\n\n\tint event__preprocess_sample(const event_t *self,\n\t\t\t\t struct addr_location *al,\n\t\t\t\t symbol_filter_t filter)\n\nIt receives the event itself and will insert new threads in the\nglobal threads list and resolve the map and symbol, 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 addr_location *al,\n\t\t\t\t\tsymbol_filter_t filter)\n\nThis one will, given a thread (userspace or the kernel kthread\none), will find the given type (MAP__FUNCTION now, MAP__VARIABLE\ntoo in the 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 plain function\nresolution, like \u0027kmem\u0027, can use this other one:\n\n\tstruct symbol *thread__find_function(struct thread *self, u64 addr,\n\t\t\t\t\t symbol_filter_t filter)\n\nSo, to resolve a kernel symbol, that is all the \u0027kmem\u0027 tool\nneeds, its just a matter of calling:\n\n\tsym \u003d thread__find_function(kthread, addr, NULL);\n\nThe \u0027filter\u0027 parameter is needed because we do lazy\nparsing/loading of ELF symtabs

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.
