For printing these information, the perf.data file must have been obtained by group read and using special events cycles, ref-cycles, msr/tsc/, msr/aperf/ or msr/mperf/. - Freq (MHz): The frequency during the sample interval. Needs cycles ref-cycles event. - CPU%: CPU utilization during the sample interval. Needs ref-cycles and msr/tsc/ events. - CORE_BUSY%: actual percent performance (APERF/MPERF%) during the sample interval. Needs msr/aperf/ and msr/mperf/ events. Here is an example: $ perf record -e '{cycles,ref-cycles,msr/tsc/,msr/mperf/,msr/aperf/}:S' ~/tchain_edit $ perf report --stdio --group --show-freq-perf Overhead FREQ MHz CPU% CORE_BUSY% Command Shared Object Symbol ........................................ ......... ..... .......... ........... ................ ...................... 99.54% 99.54% 99.53% 99.53% 99.53% 2301 96 99 tchain_edit tchain_edit [.] f3 0.20% 0.20% 0.20% 0.20% 0.20% 2301 98 99 tchain_edit tchain_edit [.] f2 0.05% 0.05% 0.05% 0.05% 0.05% 2300 98 99 tchain_edit [kernel.vmlinux] [k] read_tsc Changes since V1: - Save cpu max freq to header when recording - Read cpu max freq and msr type from header when reporting Changes since V2: - Introduce generic FEAT for CPU related data stored - Make cpu max freq and msr type part of perf_session_env - rename cpu_u to cpu_util - Don't save sample value in perf_sample and discards new iterator. Calculating the freq_perf_info in add_entry_cb callback - Introduce symbol_conf.freq_perf_type for related hpp column visibility Changes since V3: - add a identifier 'tag' for CPU attributes, max frequency. - add backpointers to evlist for env, and evsel for evlist. - Use bitmask for freq_perf_type - Replace macros by functions to caculate freq, cpu_util and core_busy - Move all caculation codes under symbol_conf.show_freq_perf condition. Changes since V4: - Store cpu attributes id as tag and more readable cpu_attr Changes since V5: - Rename freq to max_freq and use it - Add a loop in process_cpu_attributes to facility future extension Changes since V6: - Split rename perf_session_env and add backpointer to evlist patches Arnaldo Carvalho de Melo (1): perf evsel: Add a backpointer to the evlist a evsel is in Kan Liang (7): perf,tools: introduce generic FEAT for CPU attributes perf,tools: read msr pmu type from header. perf,tools: rename perf_session_env to perf_env perf,tools: add backpointer for perf_env to evlist perf,tools: Dump per-sample freq/CPU%/CORE_BUSY% in report -D perf,tools: caculate and save freq/CPU%/CORE_BUSY% in he_stat perf,tools: Show freq/CPU%/CORE_BUSY% in perf report --stdio tools/perf/Documentation/perf-report.txt | 12 ++++++ tools/perf/arch/common.c | 4 +- tools/perf/arch/common.h | 2 +- tools/perf/builtin-report.c | 56 +++++++++++++++++++++++++ tools/perf/ui/browser.h | 4 +- tools/perf/ui/browsers/header.c | 2 +- tools/perf/ui/browsers/hists.c | 12 +++--- tools/perf/ui/hist.c | 71 +++++++++++++++++++++++++++++--- tools/perf/util/cpumap.c | 32 ++++++++++++++ tools/perf/util/cpumap.h | 1 + tools/perf/util/evlist.c | 2 + tools/perf/util/evlist.h | 1 + tools/perf/util/evsel.c | 2 + tools/perf/util/evsel.h | 4 ++ tools/perf/util/header.c | 63 ++++++++++++++++++++++++++++ tools/perf/util/header.h | 17 +++++++- tools/perf/util/hist.h | 7 +++- tools/perf/util/session.c | 36 +++++++++++++--- tools/perf/util/session.h | 64 ++++++++++++++++++++++++++++ tools/perf/util/sort.c | 3 ++ tools/perf/util/sort.h | 3 ++ tools/perf/util/symbol.c | 4 +- tools/perf/util/symbol.h | 16 +++++-- 23 files changed, 387 insertions(+), 31 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
