perf bench numa: Show more stats of particular threads in verbose mode (2015-04-28 09:57:26 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Add 'perf stat' metrics support for exclude_(host|guest|hv|idle) (Jiri Olsa)
- Fix 'perf stat' metrics calculation with event qualifiers (Andi Kleen)
- Improve event parsing error reporting (Jiri Olsa)
- Fix 'perf trace' --filter-pids OPTION description (Arnaldo Carvalho de Melo)
- Clarify that 'perf trace -e' is about syscalls, not perf events in general (Arnaldo Carvalho de Melo)
- Show error message when 'perf data' conversion failed (He Kuang)
- Remove all probe matches given pattern at once in 'perf probe --del' (Masami Hiramatsu)
- Make 'perf probe --funcs' option exclusive (Masami Hiramatsu)
- Document --children option (top, report) in more detail (Namhyung Kim)
- Show more stats of particular threads in verbose mode in 'perf bench numa' (Petr Holasek)
Infrastructure:
- AUX area tracing work needed for processing Intel PT data (Adrian Hunter)
- Add build tests for building perf from kernel source root and tools (Jiri Olsa)
- Enable 'perf data' stream flush within processing (Jiri Olsa)
- Add support for setting ordered_events queue size in 'perf data' (Jiri Olsa)
- Refactor the perf hists browser (top, report) to break down big function into
smaller ones, remove unused state (Namhyung Kim)
- Switch 'perf data' to libbabeltrace's multiple cpu stream files (Sebastian Andrzej Siewior)
- Fix duplicate field names and avoid reserved keywords in 'perf data' CTF support (Wang Nan)
- Fix signedness of value in 'perf data' (Wang Nan)
- Use getconf to determine number of online CPUs, making the build process to find the
right number of online CPUs on ARM (Will Deacon)
