Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull more perf updates from Ingo Molnar: "A second (and last) round of late coming fixes and changes, almost all of them in perf tooling: User visible tooling changes: - Add period data column and make it default in 'perf script' (Jiri Olsa) - Add a visual cue for toggle zeroing of samples in 'perf top' (Taeung Song) - Improve callchains when using libunwind (Namhyung Kim) Tooling fixes and infrastructure changes: - Fix for double free in 'perf stat' when using some specific invalid command line combo (Yasser Shalabi) - Fix off-by-one bugs in map->end handling (Stephane Eranian) - Fix off-by-one bug in maps__find(), also related to map->end handling (Namhyung Kim) - Make struct symbol->end be the first addr after the symbol range, to make it match the convention used for struct map->end. (Arnaldo Carvalho de Melo) - Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat live' (Jiri Olsa) - Fix python test build by moving callchain_param to an object linked into the python binding (Jiri Olsa) - Document sysfs events/ interfaces (Cody P Schafer) - Fix typos in perf/Documentation (Masanari Iida) - Add missing 'struct option' forward declaration (Arnaldo Carvalho de Melo) - Add option to copy events when queuing for sorting across cpu buffers and enable it for 'perf kvm stat live', to avoid having events left in the queue pointing to the ring buffer be rewritten in high volume sessions. (Alexander Yarygin, improving work done by David Ahern): - Do not include a struct hists per perf_evsel, untangling the histogram code from perf_evsel, to pave the way for exporting a minimalistic tools/lib/api/perf/ library usable by tools/perf and initially by the rasd daemon being developed by Borislav Petkov, Robert Richter and Jean Pihet. (Arnaldo Carvalho de Melo) - Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and thread maps mean syswide monitoring, reducing the boilerplate for tools that only want system wide mode. (Arnaldo Carvalho de Melo) - Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete should be just a front end for exit + free (Arnaldo Carvalho de Melo) - Add support to new style format of kernel PMU event. (Kan Liang) and other misc fixes" * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (45 commits) perf script: Add period as a default output column perf script: Add period data column perf evsel: No need to drag util/cgroup.h perf evlist: Add missing 'struct option' forward declaration perf evsel: Move exit stuff from __delete to __exit kprobes/x86: Remove stale ARCH_SUPPORTS_KPROBES_ON_FTRACE define perf kvm stat live: Enable events copying perf session: Add option to copy events when queueing perf Documentation: Fix typos in perf/Documentation perf trace: Use thread_{,_set}_priv helpers perf kvm: Use thread_{,_set}_priv helpers perf callchain: Create an address space per thread perf report: Set callchain_param.record_mode for future use perf evlist: Fix for double free in tools/perf stat perf test: Add test case for pmu event new style format perf tools: Add support to new style format of kernel PMU event perf tools: Parse the pmu event prefix and suffix Revert "perf tools: Default to cpu// for events v5" perf Documentation: Remove Ruplicated docs for powerpc cpu specific events perf Documentation: sysfs events/ interfaces ...

578Date: 2013/01/08 35 Each file (except for some of those with a '.' in them, '.unit'
36 and '.scale') in the 'events' directory describes a single
37 performance monitoring event supported by the <pmu>. The name
38 of the file is the name of the event.
39
40 File contents:
41
42 <term>[=<value>][,<term>[=<value>]]...
43
44 Where <term> is one of the terms listed under
45 /sys/bus/event_source/devices/<pmu>/format/ and <value> is
46 a number is base-16 format with a '0x' prefix (lowercase only).
47 If a <term> is specified alone (without an assigned value), it
48 is implied that 0x1 is assigned to that <term>.
579 49
50 Examples (each of these lines would be in a seperate file):
51
52 event=0x2abc
53 event=0x423,inv,cmask=0x3
54 domain=0x1,offset=0x8,starting_index=0xffff
55
56 Each of the assignments indicates a value to be assigned to a
57 particular set of bits (as defined by the format file
58 corresponding to the <term>) in the perf_event structure passed
59 to the perf_open syscall.
