    765532c8 (perf script: Finish the rename from trace to script,
    2010-12-23) made a mistake during find-and-replace replacing
    "../../../util/trace-event.h" with "../../../util/script-event.h", a
    non-existent file. Fix this include.

  • b22e79395   perf perl scripts: Fix SIGALRM and pipe read race for rwtop ... Browse Code »

    Fixing rwtop script race. The issue is caused by rwtop script triggering
    SIGALRM and underneath pipe reading layer reporting error when
    interrupted.

    Fixing this by setting SA_RESTART for rwtop SIGALRM handler, which
    avoids interruption of the pipe reading layer.

    The discussion for this issue & fix is here:

  • 1de7b7e89   perf script: Remove workqueue-stats script ... Browse Code »

    The tracepoints used by the workqueue-stats script no longer exist so
    trying to run the script results in:

    # perf script record workqueue-stats
    invalid or unsupported event: 'workqueue:workqueue_creation'
    Run 'perf list' for a list of valid events

    So remove the script until it can be reworked using the new workqueue
    tracepoints.

  • 0076d546b   perf scripts python: Add event_analyzing_sample.py as a sample for general event handling ... Browse Code »

    Currently only trace point events are supported in perf/python script,
    the first 3 patches of this serie add the support for all types of
    events. This script is just a simple sample to show how to gather the
    basic information of the events and analyze them.

    This script will create one object for each event sample and insert them
    into a table in a database, then leverage the simple SQL commands to
    sort/group them. User can modify or write their brand new functions
    according to their specific requirment.

    Here is the sample of how to use the script:

    $ perf record -a tree
    $ perf script -s process_event.py

    There is 100 records in gen_events table
    Statistics about the general events grouped by thread/symbol/dso:

  • 63e03724b   perf script: Add drop monitor script ... Browse Code »

    A while back I created the dropmonitor protocol, which allowed users to get
    reports of dropped frames communicated to them via a netlink socket.

    While useful, several people have now asked that I integrate the ability
    to do drop monitoring with perf, so they don't have to run additional
    tools.

    This patch adds a drop monitor script to the perf suite, and provides
    the same output that the netlink socket does.

  • 359d5106a   perf: Add a script to show packets processing ... Browse Code »

    Add a perf script which shows packets processing and processed
    time. It helps us to investigate networking or network devices.

    If you want to use it, install perf and record perf.data like
    following.

    If you set script, perf gathers records until it ends.
    If not, you must Ctrl-C to stop recording.

    And if you want a report from record,

    If you use some options, you can limit the output.
    Option is below.

    tx: show only tx packets processing
    rx: show only rx packets processing
    dev=: show processing on this device
    debug: work with debug mode. It shows buffer status.

    For example, if you want to show received packets processing
    associated with eth4,

    106133.171439sec cpu=0
    irq_entry(+0.000msec irq=24:eth4)
    |
    softirq_entry(+0.006msec)
    |
    |---netif_receive_skb(+0.010msec skb=f2d15900 len=100)
    | |
    | skb_copy_datagram_iovec(+0.039msec 10291::10291)
    |
    napi_poll_exit(+0.022msec eth4)

    This perf script helps us to analyze the processing time of a
    transmit/receive sequence.

    This makes the vertical navigation scrollable so that all of the

    Without vertical zoom, it is not possible to see all CPUs in a trace
    taken on a larger machine. This patch parameterizes the height and
    spacing of CPUs so that you can fit more cpus into the screen.

    Ideally we should dynamically size/space the CPU rectangles with some
    minimum threshold. Until then, this patch is a stop-gap.

    EVT_KEY_DOWN and EVT_LEFT_DOWN events are not bound to the RootFrame
    event handler. As a result, zoom/scroll via keyboard events do not
    work. This patch adds the missing bindings.

    Stop printing an error message when we don't have the letter
    for a given task state. All we need to know is if the task is
    in the TASK_RUNNING state.

  • 749e50741   perf, sched migration: Handle ignored migrate out events ... Browse Code »

    Migrate out events may happen on tasks that are not in the
    runqueue, for example this is the case for tasks that are
    sleeping. In this case, we don't want to log the migrate out
    event in the source runqueue because the task is not eventually
    in the runqueue and we have already logged its sleep event.

    This fixes timeslices that spuriously propagate a sleep event
    from the previous timeslice.

  • 880d22f24   perf: New migration tool overview ... Browse Code »

    This brings a GUI tool that displays an overview of the load
    of tasks proportion in each CPUs.

    The CPUs forward progress is cut in timeslices. A new timeslice
    is created for every runqueue event: a task gets pushed out or
    pulled in the runqueue.

    For each timeslice, every CPUs rectangle is colored with a red
    power that describes the local load against the total load.
    This more red is the rectangle, the higher is the given CPU load.
    This load is the number of tasks running on the CPU, without
    any distinction against the scheduler policy of the tasks, for
    now.

    Also for each timeslice, the event origin is depicted on the
    CPUs that triggered it using a thin colored line on top of the
    rectangle timeslice.

    These events are:

    * sleep: a task went to sleep and has then been pulled out the
    runqueue. The origin color in the thin line is dark blue.

    * wake up: a task woke up and has then been pushed in the
    runqueue. The origin color is yellow.

    * wake up new: a new task woke up and has then been pushed in the
    runqueue. The origin color is green.

    * migrate in: a task migrated in the runqueue due to a load
    balancing operation. The origin color is violet.

    * migrate out: reverse of the previous one. Migrate in events
    usually have paired migrate out events in another runqueue.
    The origin color is light blue.

    Clicking on a timeslice provides the runqueue event details
    and the runqueue state.

    The CPU rectangles can be navigated using the usual arrow
    controls. Horizontal zooming in/out is possible with the
    "+" and "-" buttons.

  • c02514850   perf scripts python: Give field dict to unhandled callback ... Browse Code »

    trace_unhandled() callback does not allow to access event fields, this patch
    resolves the problem.

    It can also been used as a more pythonic and flexible way for script writters
    to demux event types

    This will for example greatly simplify pytimechart event demux.
