Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "Kernel side changes mostly consist of work on x86 PMU drivers: - x86 Intel PT (hardware CPU tracer) improvements (Alexander Shishkin) - x86 Intel CQM (cache quality monitoring) improvements (Thomas Gleixner) - x86 Intel PEBSv3 support (Peter Zijlstra) - x86 Intel PEBS interrupt batching support for lower overhead sampling (Zheng Yan, Kan Liang) - x86 PMU scheduler fixes and improvements (Peter Zijlstra) There's too many tooling improvements to list them all - here are a few select highlights: 'perf bench': - Introduce new 'perf bench futex' benchmark: 'wake-parallel', to measure parallel waker threads generating contention for kernel locks (hb->lock). (Davidlohr Bueso) 'perf top', 'perf report': - Allow disabling/enabling events dynamicaly in 'perf top': a 'perf top' session can instantly become a 'perf report' one, i.e. going from dynamic analysis to a static one, returning to a dynamic one is possible, to toogle the modes, just press 'f' to 'freeze/unfreeze' the sampling. (Arnaldo Carvalho de Melo) - Make Ctrl-C stop processing on TUI, allowing interrupting the load of big perf.data files (Namhyung Kim) 'perf probe': (Masami Hiramatsu) - Support glob wildcards for function name - Support $params special probe argument: Collect all function arguments - Make --line checks validate C-style function name. - Add --no-inlines option to avoid searching inline functions - Greatly speed up 'perf probe --list' by caching debuginfo. - Improve --filter support for 'perf probe', allowing using its arguments on other commands, as --add, --del, etc. 'perf sched': - Add option in 'perf sched' to merge like comms to lat output (Josef Bacik) Plus tons of infrastructure work - in particular preparation for upcoming threaded perf report support, but also lots of other work - and fixes and other improvements. See (much) more details in the shortlog and in the git log" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (305 commits) perf tools: Configurable per thread proc map processing time out perf tools: Add time out to force stop proc map processing perf report: Fix sort__sym_cmp to also compare end of symbol perf hists browser: React to unassigned hotkey pressing perf top: Tell the user how to unfreeze events after pressing 'f' perf hists browser: Honour the help line provided by builtin-{top,report}.c perf hists browser: Do not exit when 'f' is pressed in 'report' mode perf top: Replace CTRL+z with 'f' as hotkey for enable/disable events perf annotate: Rename source_line_percent to source_line_samples perf annotate: Display total number of samples with --show-total-period perf tools: Ensure thread-stack is flushed perf top: Allow disabling/enabling events dynamicly perf evlist: Add toggle_enable() method perf trace: Fix race condition at the end of started workloads perf probe: Speed up perf probe --list by caching debuginfo perf probe: Show usage even if the last event is skipped perf tools: Move libtraceevent dynamic list to separated LDFLAGS variable perf tools: Fix a problem when opening old perf.data with different byte order perf tools: Ignore .config-detected in .gitignore perf probe: Fix to return error if no probe is added ...
