If we do fallback, this will print\nout a warning if report -D was invoked.\n\nThis patch adds the test in perf_session__new so that we only need to\ntest once per session.

For example, running \u0027perf probe --list\u0027 on a\nPowerPC machine would fail to properly set the list_events bool\nand would therefore print out the usage information and\nterminate.\n\nThis patch makes OPT_BOOLEAN work as expected with a bool\ndatatype. For cases where the original OPT_BOOLEAN was\nintentionally being used to increment an int each time it was\npassed in on the command line, this patch introduces OPT_INCR\nwith the old behaviour of OPT_BOOLEAN (the verbose variable is\ncurrently the only such example of this).\n\nI have reviewed every use of OPT_BOOLEAN to verify that a true\nC99 bool was passed. Where integers were used, I verified that\nthey were only being used for boolean logic and changed them to\nbools to ensure that they would not be mistakenly used as ints.\nThe major exception was the verbose variable which now uses\nOPT_INCR instead of OPT_BOOLEAN.\n\nSigned-off-by: Ian Munsie \u003cimunsie@au.ibm.com\u003e\nAcked-by: David S.

      "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.
