The default when just tracepoint events are found in a perf.data file is to format it like ftrace, using the libtraceevent formatters, plugins, etc (Namhyung Kim) - Add support in 'perf script' to process 'perf stat record' generated files, culminating in a python perf script that calculates CPI (Cycles per Instruction) (Jiri Olsa) - Show random perf tool tips in the 'perf report' bottom line (Namhyung Kim) - perf report now defaults to --group if the perf.data file has grouped events, try it with: # perf record -e '{cycles,instructions}' -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.093 MB perf.data (1247 samples) ] # perf report # Samples: 1K of event 'anon group { cycles, instructions }' # Event count (approx.): 1955219195 # # Overhead Command Shared Object Symbol 2.86% 0.22% swapper [kernel.kallsyms] [k] intel_idle 1.05% 0.33% firefox libxul.so [.] js::SetObjectElement 1.05% 0.00% kworker/0:3 [kernel.kallsyms] [k] gen6_ring_get_seqno 0.88% 0.17% chrome chrome [.] 0x0000000000ee27ab 0.65% 0.86% firefox libxul.so [.] js::ValueToId<(js::AllowGC)1> 0.64% 0.23% JS Helper libxul.so [.] js::SplayTree::splay 0.62% 1.27% firefox libxul.so [.] js::GetIterator 0.61% 1.74% firefox libxul.so [.] js::NativeSetProperty 0.61% 0.31% firefox libxul.so [.] js::SetPropertyByDefining User visible fixes: - Coect data mmaps so that the DWARF unwinder can handle usecases needing them, like softice (Jiri Olsa) - Decay callchains in fractal mode, fixing up cases where 'perf top -g' would show entries with more than 100% (Namhyung Kim) Infrastructure: - Sync tools/lib with the lib/ in the kernel sources for find_bit.c and move bitmap.[ch] from tools/perf/util/ to tools/lib/ (Arnaldo Carvalho de Melo) - No need to set attr.sample_freq in some 'perf test' entries that only want to deal with PERF_RECORD_ meta-events, improve a bit error output for CQM test (Arnaldo Carvalho de Melo) - Fix python binding build, adding some missing object files now required due to cpumap using find_bit stuff (Arnaldo Carvalho de Melo) - tools/build improvemnts (Jiri Olsa) - Add more files to cscope/ctags databases (Jiri Olsa) - Do not show 'trace' in 'perf help' if it is not compiled in (Jiri Olsa) - Make perf_evlist__open() open evsels with their cpus and threads, like perf record does, making them consistent (Adrian Hunter) - Fix pmu snapshot initialization bug (Stephane Eranian) - Add missing headers in perf's MANIFEST (Wang Nan) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Adrian Hunter (1): perf evlist: Make perf_evlist__open() open evsels with their cpus and threads (like perf record does) Arnaldo Carvalho de Melo (10): perf tests: No need to set attr.sample_freq in the perf time to TSC test perf evlist: Introduce perf_evlist__new_dummy constructor perf test: Use "dummy" events in the PERF_RECORD_ test perf test: No need for setting attr.sample_freq on the RECORD test perf python: Add missing files to binding link list perf tests: No need to set attr.sample_freq for tracking !PERF_RECORD_SAMPLE perf tests: Give a bit more information on the CQM test failure path tools lib: Move find_next_bit.c to tools/lib/ tools lib: Sync tools/lib/find_bit.c with the kernel tools lib: Move bitmap.[ch] from tools/perf/ to tools/{lib,include}/ Jiri Olsa (25): tools build feature: Fix feature_check_display_code typo tools build feature: Move dwarf post unwind choice output into perf tools build feature: Introduce feature_assign macro tools build feature: Use value assignment form for FEATURE-DUMP file perf build: Use FEATURE-DUMP in bpf subproject perf stat record: Keep sample_type 0 for pipe session perf script: Process cpu/threads maps perf script: Process stat config event perf script: Add process_stat/process_stat_interval scripting interface perf script: Add stat default handlers perf script: Add python support for stat events perf cpumap: Fix cpu conversion in cpu_map__from_entries perf script: Display stat events by default perf script: Add stat-cpi.py script perf tools: Do not show trace command if it's not compiled in perf script: Align event name properly perf tools: Include all tools/lib directory for tags/cscope/TAGS targets perf tools: Remove list entry from struct sort_entry perf tools: Add overhead/overhead_children keys defaults via string perf diff: Use perf_hpp__register_sort_field interface perf evlist: Remove perf_evlist__(enable|disable)_event functions perf unwind: Use find_map function in access_dso_mem perf unwind: Check for mmaps also in MAP__VARIABLE tree perf libdw: Check for mmaps also in MAP__VARIABLE tree perf record: Store data mmaps for dwarf unwind Namhyung Kim (21): perf hist: Pass struct sample to __hists__add_entry() perf hist: Save raw_data/size for tracepoint events tools lib traceevent: Factor out and export print_event_field[s]() perf top: Create the evlist sooner perf tools: Pass evlist to setup_sorting() perf tools: Add dynamic sort key for tracepoint events perf tools: Try to show pretty printed output for dynamic sort keys perf tools: Add 'trace' sort key perf report/top: Add --raw-trace option perf tools: Support shortcuts for events in dynamic sort keys perf tools: Support '.*' dynamic sort key perf tools: Skip dynamic fields not defined for current event perf tools: Add 'trace_fields' dynamic sort key perf tools: Make 'trace' or 'trace_fields' sort key default for tracepoint events perf tools: Add all matching dynamic sort keys for field name perf report: Add documentation for dynamic sort keys perf top: Decay periods in callchains perf report: Change default to use event group view perf hists: Export a couple of hist functions perf report: Show random usage tip on the help line perf evlist: Add --trace-fields option to show trace fields Stephane Eranian (1): perf pmu: fix alias->snapshot missing initialization bug Wang Nan (1): perf tools: Add missing headers in perf's MANIFEST tools/build/Makefile.feature | 41 +- tools/{perf/util => }/include/linux/bitmap.h | 2 + tools/{perf/util => lib}/bitmap.c | 0 tools/lib/bpf/Makefile | 4 + tools/lib/find_bit.c | 84 +++ tools/lib/traceevent/event-parse.c | 129 ++--- tools/lib/traceevent/event-parse.h | 4 + tools/lib/util/find_next_bit.c | 89 --- tools/perf/Build | 1 + tools/perf/Documentation/perf-evlist.txt | 3 + tools/perf/Documentation/perf-report.txt | 27 + tools/perf/Documentation/perf-top.txt | 3 + tools/perf/Documentation/tips.txt | 14 + tools/perf/MANIFEST | 4 +- tools/perf/Makefile.perf | 7 +- tools/perf/arch/x86/tests/intel-cqm.c | 2 +- tools/perf/arch/x86/tests/perf-time-to-tsc.c | 1 -
