  • eddaef889   perf annotate: Add -q/--quiet option ... Browse Code »

    The -q/--quiet option is to suppress any message. Sometimes users just
    want to see the numbers and it can be used for that case.

  • 53fe4ba1d   perf annotate: Introduce --stdio-color to setup the color output mode selection ... Browse Code »

    'perf annotate --stdio' will colorize entries with most hits and
    possibly some other aspects of its output, but those colors gets
    suppressed if we redirect the output to a non-tty, allow keeping the
    colors by adding a new option, --stdio-color, now this use case will
    also output escape sequences for colors:

    $ perf annotate --stdio-color | more

    Add --group option to enable event grouping. When enabled, all the
    group members information will be shown with the leader so skip
    non-leader events.

    It only supports --stdio output currently. Later patches will extend
    additional features.

  • 7a4ec9388   perf tools: Allow user to indicate path to objdump in command line ... Browse Code »

    When analyzing perf data from hosts of other architecture than one of
    the local host it's useful to call objdump that is part of a toolchain
    for that architecture. Instead of calling regular objdump, call one that
    user specified in command line.

  • efad14150   perf report: Accept fifos as input file ... Browse Code »

    The default input file for perf report is not handled the same way as
    perf record does it for its output file. This leads to unexpected
    behavior of perf report, etc. E.g.:

    # perf record -a -e cpu-cycles sleep 2 | perf report | cat
    failed to open perf.data: No such file or directory (try 'perf record' first)

    While perf record writes to a fifo, perf report expects perf.data to be
    read. This patch changes this to accept fifos as input file.

    Applies to the following commands:

    perf annotate
    perf buildid-list
    perf evlist
    perf kmem
    perf lock
    perf report
    perf sched
    perf script
    perf timechart

    Also fixes char const* -> const char* type declaration for filename
    strings.

    v2:
    * Prevent potential null pointer access to input_name in
    builtin-report.c. Needed due to removal of patch "perf report: Setup
    browser if stdout is a pipe"

  • c8e667203   perf tools: make -C consistent across commands (for cpu list arg) ... Browse Code »

    Currently the meaning of -C varies by perf command: for perf-top,
    perf-stat, perf-record it means cpu list. For perf-report it means comm
    list. Then perf-annotate, perf-report and perf-script use -c for cpu
    list.

    Fix annotate, report and script to use -C for cpu list to be consistent
    with top, stat and record. This means report needs to use -c for comm
    list which does introduce a backward compatibility change.

    v1 -> v2
    - update perf-script.txt too

    If you have --symfs in perf report, then you also need it for perf

  • 3e6a2a7f3   perf annotate: Make output more readable ... Browse Code »

    This patch adds two new options to perf annotate:
    - --no-asm-raw : Do not display raw instruction encodings
    - --no-source : Do not interleave source code with assembly code

    We believe those options make the output of annotate more readable.

    Systematically displaying source can make it hard to follow code and
    especially optimized code.

    Raw encodings are not useful in most cases.

  • 5d67be97f   perf report/annotate/script: Add option to specify a CPU range ... Browse Code »

    Add an option to perf report/annotate/script to specify which
    CPUs to operate on. This enables us to take a single system wide
    profile and analyse each CPU (or group of CPUs) in isolation.

    This was useful when profiling a multiprocess workload where the
    bottleneck was on one CPU but this was hidden in the overall
    profile. Per process and per thread breakdowns didn't help
    because multiple processes were running on each CPU and no
    single process consumed an entire CPU.

    The patch converts the list of CPUs returned by cpu_map__new
    into a bitmap for fast lookup. I wanted to use -C to be
    consistent with perf top/record/stat, but unfortunately perf
    report already uses -C .

    v2: Incorporate suggestions from David Ahern:
    - Added -c to perf script
    - Check that SAMPLE_CPU is set when -c is used
    - Update documentation

    v3: Create perf_session__cpu_bitmap()
