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: - x86 Intel uncore driver cleanups and enhancements (Kan Liang) - group scheduling and other fixes (Song Liu - store frame pointer in the sample traces for better profiling (Alexey Budankov) - compat fixes/enhancements (Eugene Syromiatnikov) Tooling side changes, which you can build and install in a single step via: make -C tools/perf clean install perf annotate: - Support 'perf annotate --group' for non-explicit recorded event "groups", showing multiple columns, one for each event, just like when dealing with explicit event groups (those enclosed with {}) (Jin Yao) - Record min/max LBR cycles (>= Skylake) and add 'perf annotate' TUI hotkey to show it (c) (Jin Yao) perf bpf: - Add infrastructure to help in writing eBPF C programs to be used with '-e name.c' type events in tools such as 'record' and 'trace', with headers for common constructs and an examples directory that will get populated as we add more such helpers and the 'perf bpf' (Arnaldo Carvalho de Melo) perf stat: - Display time in precision based on std deviation (Jiri Olsa) - Add --table option to display time of each run (Jiri Olsa) - Display length strings of each run for --table option (Jiri Olsa) perf buildid-cache: - Add --list and --purge-all options (Ravi Bangoria) perf test: - Let 'perf test list' display subtests (Hendrik Brueckner) perf pti: - Create extra kernel maps to help in decoding samples in x86 PTI entry trampolines (Adrian Hunter) - Copy x86 PTI entry trampoline sections in the kcore copy used for annotation and intel_pt CPU traces decoding (Adrian Hunter) ... and a lot of other fixes, enhancements and cleanups I did not list, see the shortlog and git log for details" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (111 commits) perf/x86/intel/uncore: Clean up client IMC uncore perf/x86/intel/uncore: Expose uncore_pmu_event*() functions perf/x86/intel/uncore: Support IIO free-running counters on SKX perf/x86/intel/uncore: Add infrastructure for free running counters perf/x86/intel/uncore: Add new data structures for free running counters perf/x86/intel/uncore: Correct fixed counter index check in generic code perf/x86/intel/uncore: Correct fixed counter index check for NHM perf/x86/intel/uncore: Introduce customized event_read() for client IMC uncore perf/x86: Store user space frame-pointer value on a sample perf/core: Wire up compat PERF_EVENT_IOC_QUERY_BPF, PERF_EVENT_IOC_MODIFY_ATTRIBUTES perf/core: Fix bad use of igrab() perf/core: Fix group scheduling with mixed hw and sw events perf kcore_copy: Amend the offset of sections that remap kernel text perf kcore_copy: Copy x86 PTI entry trampoline sections perf kcore_copy: Get rid of kernel_map perf kcore_copy: Iterate phdrs perf kcore_copy: Layout sections perf kcore_copy: Calculate offset from phnum perf kcore_copy: Keep a count of phdrs perf kcore_copy: Keep phdr data in a list ...
