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)
-------- ------ ---------------- --------- --------- --------

1.874746 [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)
