75e0b5f010 perf scripting perl: Force to use stdbool
When building perf for arm64 I hit a warning (and be treated as an
error) like below:

 aarch64-oe-linux-gcc -o .../scripts/perl/Perf-Trace-Util/Context.o -c -Wbad-function-cast \
         ... scripts/perl/Perf-Trace-Util/Context.c

                  from Context.xs:23:

  ^

    #define bool _Bool

Looks like the failure is caused by arm64 uapi/asm/sigcontext.h, which
includes linux/types.h while other archs not.

Current perl consider this problem:

http://perl5.git.perl.org/perl.git/commit/bd31be4baa3ee68abdb92c0db3200efe0fad903b

However there are users which use old version of perl.

This patch includes stdbool.h before Context.xs and define HAS_BOOL to
prevent perl'e headers define its own 'bool'. Code is learn from perl's
git tree.

2987e32f75 perf script: Add Python script to export to postgresql
Add a Python script to export to a postgresql database.

The script requires the Python pyside module and the Qt PostgreSQL
driver.  The packages needed are probably named "python-pyside" and
"libqt4-sql-psql"

The caller of the script must be able to create postgresql databases.

The script takes the database name as a parameter.  The database and
database tables are created.  Data is written to flat files which are
then imported using SQL COPY FROM.

Example:

  $ perf record ls
  ...
  $ perf script report export-to-postgresql lsdb

My notes (which may be out-of-date) on setting up postgresql so you can
create databases:

fedora:

        $ sudo yum install postgresql postgresql-server python-pyside qt-postgresql
        $ sudo su - postgres -c initdb
        $ sudo service postgresql start
        $ sudo su - postgres
        $ createuser -s <your username>

I used the the unix user name in createuser.

If it fails, try createuser without -s and answer the following question
to allow your user to create tables:

        Shall the new role be a superuser? (y/n) y

ubuntu:

        $ sudo apt-get install postgresql
        $ sudo su - postgres
        $ createuser <your username>
        Shall the new role be a superuser? (y/n) y

You may want to disable automatic startup.  One way is to edit
/etc/postgresql/9.3/main/start.conf.  Another is to disable the init
script e.g. sudo update-rc.d postgresql disable

0076d546b4 perf scripts python: Add event_analyzing_sample.py as a sample for general event handling
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:

02f1c33f7d perf scripts python: Add a python library EventClass.py
This library defines several class types for perf events which could
help to better analyze the event samples. Currently there are just a few
classes, PerfEvent is the base class for all perf events,  PebsEvent is
a HW base Intel x86 PEBS event, and user could add more SW/HW event
classes based on requriements.

63e03724b5 perf script: Add drop monitor script
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.

359d5106a2 perf: Add a script to show packets processing
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

best the screen with CPU rectangles, but that's for later.

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.

749e507411 perf, sched migration: Handle ignored migrate out events
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.

880d22f247 perf: New migration tool overview
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.

- printing the totals and clearing the hashes in the signal handler
  eventually leads to various random and serious problems when running

  invoked frequently enough that it doesn't affect the timeliness of
  the output.
