Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf update from Ingo Molnar: "Lots of changes in this cycle as well, with hundreds of commits from over 30 contributors. Most of the activity was on the tooling side. Higher level changes: - New 'perf kvm' analysis tool, from Xiao Guangrong. - New 'perf trace' system-wide tracing tool - uprobes fixes + cleanups from Oleg Nesterov. - Lots of patches to make perf build on Android out of box, from Irina Tirdea - Extend ftrace function tracing utility to be more dynamic for its users. It allows for data passing to the callback functions, as well as reading regs as if a breakpoint were to trigger at function entry. The main goal of this patch series was to allow kprobes to use ftrace as an optimized probe point when a probe is placed on an ftrace nop. With lots of help from Masami Hiramatsu, and going through lots of iterations, we finally came up with a good solution. - Add cpumask for uncore pmu, use it in 'stat', from Yan, Zheng. - Various tracing updates from Steve Rostedt - Clean up and improve 'perf sched' performance by elliminating lots of needless calls to libtraceevent. - Event group parsing support, from Jiri Olsa - UI/gtk refactorings and improvements from Namhyung Kim - Add support for non-tracepoint events in perf script python, from Feng Tang - Add --symbols to 'script', similar to the one in 'report', from Feng Tang. Infrastructure enhancements and fixes: - Convert the trace builtins to use the growing evsel/evlist tracepoint infrastructure, removing several open coded constructs like switch like series of strcmp to dispatch events, etc. Basically what had already been showcased in 'perf sched'. - Add evsel constructor for tracepoints, that uses libtraceevent just to parse the /format events file, use it in a new 'perf test' to make sure the libtraceevent format parsing regressions can be more readily caught. - Some strange errors were happening in some builds, but not on the next, reported by several people, problem was some parser related files, generated during the build, didn't had proper make deps, fix from Eric Sandeen. - Introduce struct and cache information about the environment where a perf.data file was captured, from Namhyung Kim. - Fix handling of unresolved samples when --symbols is used in 'report', from Feng Tang. - Add union member access support to 'probe', from Hyeoncheol Lee. - Fixups to die() removal, from Namhyung Kim. - Render fixes for the TUI, from Namhyung Kim. - Don't enable annotation in non symbolic view, from Namhyung Kim. - Fix pipe mode in 'report', from Namhyung Kim. - Move related stats code from stat to util/, will be used by the 'stat' kvm tool, from Xiao Guangrong. - Remove die()/exit() calls from several tools. - Resolve vdso callchains, from Jiri Olsa - Don't pass const char pointers to basename, so that we can unconditionally use libgen.h and thus avoid ifdef BIONIC lines, from David Ahern - Refactor hist formatting so that it can be reused with the GTK browser, From Namhyung Kim - Fix build for another rbtree.c change, from Adrian Hunter. - Make 'perf diff' command work with evsel hists, from Jiri Olsa. - Use the only field_sep var that is set up: symbol_conf.field_sep, fix from Jiri Olsa. - .gitignore compiled python binaries, from Namhyung Kim. - Get rid of die() in more libtraceevent places, from Namhyung Kim. - Rename libtraceevent 'private' struct member to 'priv' so that it works in C++, from Steven Rostedt - Remove lots of exit()/die() calls from tools so that the main perf exit routine can take place, from David Ahern - Fix x86 build on x86-64, from David Ahern. - {int,str,rb}list fixes from Suzuki K Poulose - perf.data header fixes from Namhyung Kim - Allow user to indicate objdump path, needed in cross environments, from Maciek Borzecki - Fix hardware cache event name generation, fix from Jiri Olsa - Add round trip test for sw, hw and cache event names, catching the problem Jiri fixed, after Jiri's patch, the test passes successfully. - Clean target should do clean for lib/traceevent too, fix from David Ahern - Check the right variable for allocation failure, fix from Namhyung Kim - Set up evsel->tp_format regardless of evsel->name being set already, fix from Namhyung Kim - Oprofile fixes from Robert Richter. - Remove perf_event_attr needless version inflation, from Jiri Olsa - Introduce libtraceevent strerror like error reporting facility, from Namhyung Kim - Add pmu mappings to perf.data header and use event names from cmd line, from Robert Richter - Fix include order for bison/flex-generated C files, from Ben Hutchings - Build fixes and documentation corrections from David Ahern - Assorted cleanups from Robert Richter - Let O= makes handle relative paths, from Steven Rostedt - perf script python fixes, from Feng Tang. - Initial bash completion support, from Frederic Weisbecker - Allow building without libelf, from Namhyung Kim. - Support DWARF CFI based unwind to have callchains when %bp based unwinding is not possible, from Jiri Olsa. - Symbol resolution fixes, while fixing support PPC64 files with an .opt ELF section was the end goal, several fixes for code that handles all architectures and cleanups are included, from Cody Schafer. - Assorted fixes for Documentation and build in 32 bit, from Robert Richter - Cache the libtraceevent event_format associated to each evsel early, so that we avoid relookups, i.e. calling pevent_find_event repeatedly when processing tracepoint events. [ This is to reduce the surface contact with libtraceevents and make clear what is that the perf tools needs from that lib: so far parsing the common and per event fields. ] - Don't stop the build if the audit libraries are not installed, fix from Namhyung Kim. - Fix bfd.h/libbfd detection with recent binutils, from Markus Trippelsdorf. - Improve warning message when libunwind devel packages not present, from Jiri Olsa" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (282 commits) perf trace: Add aliases for some syscalls perf probe: Print an enum type variable in "enum variable-name" format when showing accessible variables perf tools: Check libaudit availability for perf-trace builtin perf hists: Add missing period_* fields when collapsing a hist entry perf trace: New tool perf evsel: Export the event_format constructor perf evsel: Introduce rawptr() method perf tools: Use perf_evsel__newtp in the event parser perf evsel: The tracepoint constructor should store sys:name perf evlist: Introduce set_filter() method perf evlist: Renane set_filters method to apply_filters perf test: Add test to check we correctly parse and match syscall open parms perf evsel: Handle endianity in intval method perf evsel: Know if byte swap is needed perf tools: Allow handling a NULL cpu_map as meaning "all cpus" perf evsel: Improve tracepoint constructor setup tools lib traceevent: Fix error path on pevent_parse_event perf test: Fix build failure trace: Move trace event enable from fs_initcall to core_initcall tracing: Add an option for disabling markers ...
