    Date
    From: Arnaldo Carvalho de Melo <acme@redhat.com>

    Hi Ingo,

    Please consider pulling,

    - Arnaldo

    Test results at the end.

    The following changes since commit 6a6b12e2125591e24891e6860410795ea53aed11:

    Merge tag 'perf-core-for-mingo-20161114' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core (2016-11-15 09:45:04 +0100)

    are available in the git repository at:

    git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-20161123

    for you to fetch changes up to a407b0678bc1c39d70af5fdbe6421c164b69a8c0:

    perf sched timehist: Add -V/--cpu-visual option (2016-11-23 10:44:09 -0300)

    ----------------------------------------------------------------
    perf/core improvements and fixes:

    New tool:

    - 'perf sched timehist' provides an analysis of scheduling events.

    Example usage:
    perf sched record -- sleep 1
    perf sched timehist

    By default it shows the individual schedule events, including the wait
    time (time between sched-out and next sched-in events for the task), the
    task scheduling delay (time between wakeup and actually running) and run
    time for the task:

    time cpu task name wait time sch delay run time
    [tid/pid] (msec) (msec) (msec)
    -------- ------ ---------------- --------- --------- --------
    1.874569 [0011] gcc[31949] 0.014 0.000 1.148
    1.874591 [0010] gcc[31951] 0.000 0.000 0.024
    1.874603 [0010] migration/10[59] 3.350 0.004 0.011
    1.874604 [0011] <idle> 1.148 0.000 0.035
    1.874723 [0005] <idle> 0.016 0.000 1.383
    1.874746 [0005] gcc[31949] 0.153 0.078 0.022
    ...

    Times are in msec.usec. (David Ahern, Namhyung Kim)

    Improvements:

    - Make 'perf c2c report' support -f/--force, to allow skipping the
    ownership check for root users, for instance, just like the other
    tools (Jiri Olsa)

    - Allow sorting cachelines by total number of HITMs, in addition to
    local and remote numbers (Jiri Olsa)

    Fixes:

    - Make sure errors aren't suppressed by the TUI reset at the end of
    a 'perf c2c report' session (Jiri Olsa)

    Infrastructure:

    - Initial work on having the annotate code better support multiple
    architectures, including the ability to cross-annotate, i.e. to
    annotate perf.data files collected on an ARM system on a x86_64
    workstation (Arnaldo Carvalho de Melo, Ravi Bangoria, Kim Phillips)

    - Use USECS_PER_SEC instead of hard coded number in libtraceevent (Steven Rostedt)

    - Add retrieval of preempt count and latency flags in libtraceevent (Steven Rostedt)
